"From the 1st click, my experience with Elite Sarms was great. My order was confirmed within seconds, packed & shipped that day, & delivered so quickly! Hyper Lean was my first sarms experience, & noticed an effect within a couple days. My diet has remained constant - food groups, cals, macro ratios - all the same - & have really leaned out in a short time! My body resisted change for months of dieting, carb cycling, & various training forms - up & down, & my constant stress levels didn't help at all. But with Hyper Lean I've found it does exactly what it says it does - metabolism is up as I drop fat & increase mass. I've had no negative side effects. And the strength - I find that the metabolism boost aids my recovery & my energy output, despite being in a slight caloric deficit I'm gaining muscle, and my previous PRs are history - after 6 months of struggles I feel like an athlete again! Thanks Elite Sarms - I'm impressed! " EP
After repeated intravenous (i.v.) boluses of growth hormone-releasing peptide-6 (GHRP-6) we found recently increases of growth hormone (GH), corticotropin (ACTH) and cortisol levels and of the amount of stage 2 sleep. In clinical use, oral (p.o.), intranasal (i.n.) and sublingual (s.l.) routes of administration have advantages over i.v. administration. We compared the sleep-endocrine effects of 300 microg/kg of body weight (b.w.) GHRP-6 in enteric-coated capsules given p.o. at 21.00 h and of 30 microg/kg GHRP-6 i.n. or 30 microg/kg GHRP-6 sl. given at 22.45 h in normal young male controls with placebo conditions. After GHRP-6 p.o. secretion of GH, ACTH and cortisol remained unchanged. The only effect of GHRP-6 s.l. was a trend toward an increase in GH in the first half of the night. GHRP-6 i.n. prompted a significant increase in GH concentration during the total night and a trend toward an increase in ACTH secretion during the first half of the night, whereas cortisol secretion remained unchanged. Furthermore, after GHRP-6 i.n., sleep stage 2 increased in the second half of the night by trend, and spectral analysis of total night non-rapid eye movement (REM) sleep revealed a decrease of delta power by trend. In contrast sleep stage 2 decreased during the second half of the night after GHRP-6 p.o. Our data demonstrate that GHRP-6 is capable of modulating GH and ACTH secretion as well as sleep. However, the effects depend upon dosage, duration and route of administration.
Prolactin, or estrogen gynecomastia issues: Those that are sensitive to prolactin based gynecomastia are open to problems with GHRP-6. Luckily, this is a rare occurrence, and it can be easily combated with dostinex. However, those who stack this compound with anabolic androgenic steroids may have a greater chance of getting gynecomastia. Thats why an AI (aromatase inhibitor) should be used during this kind of cycles.

This duration is a sufficient time to allow the ghrelin peptide to work through your system, and also for it to have a long lasting effect with continued use. It will work to enhance the hormone system, increase the metabolic rate, and increase lean muscle tissue levels in this period of time. As discussed above, the proper dosage for new users is 200 to 300 mcg daily, at the same time each day. For more experienced users, you can take the same dosage, 2 to 3 times a day (remember that it is the same time each day, and is best to use your injection after a meal for the best results possible).
Melanotan II is an analogue of alpha melanocyte stimulating hormone, the hormone responsible for pigmentation in skin and hair. This peptide has been shown not only to increase skin pigmentation, resulting in a substantially tanner skin tone, but also to stimulate fat loss and increase libido. Its aphrodisiac effects were so substantial that it was the basis for the development of another peptide designed exclusively to address erectile and sexual dysfunction—Bremelanotide PT 141.
In addition, scientists have observed that those who supplemented with IGF-1 experienced a preponderance of new brain cell growth and new muscle mass and new studies confirmed this to be true, even among individuals with both brain damage and muscle-wasting sarcopenia. Furthermore, research studies have found IGF-1 to increase feelings of youthfulness, improve well-being, and even to alleviate depression.
Obviously, Increasing GH (and therefore IGF-1) levels are desirable for those looking to improve their physique in terms of increased muscle mass and loss of body fat, rejuvenation and strengthening of joints through connective tissue synthesis and bone mass density increases, as well as enhancing immune response and stimulating the immune system, particularly in those of us getting on in years (ahem). For anti-ageing purposes, GHRP-6 is normally singly dosed just before bed at night with users reporting the best night’s sleep they have ever had plus some funky dreams to match (since GH is released during REM or ‘dream sleep’ so the GHRP-6 sort of ‘forces’ us to dream). For bodybuilding purposes, users attempt to mimic pulsatile GH release for best results by administering multiple times throughout the day.
Even, if you are not a fitness enthusiast, you can benefit from using the CJC 1295 Ipamorelin blend. Australia is one of the countries using them to deal with other conditions, which can affect our everyday life. There is an abundance of anti-aging clinics across the Australia that follows strict legal guidelines to sell peptides. Based in Sydney Peptides Clinics, has a good selection of peptides, to help with many conditions that occur with age, from hair loss, depression, fat loss, low libido and tanning.

The DAC technology in the CJC-1295 enables the compound to bind itself covalently with any circulating albumin, after it has been administered through a subcutaneous injection. However, the reason why the half-life could be extended from a few minutes to several days is more profound. The reactive group in the CJC-1295 binds to a peptide through bioconjugation. The peptide then finds a neucleophilic unit within the blood and reacts with it in order to create a firmer bond.


Phenylephrine is readily eliminated by sulphate conjugation in the intestinal wall, and oxidative deamination by monoamine oxidative glucuronidation in the liver. Monoamine oxidase (MAO) inhibitors can enhance the limited potential of phenylephrine for cardiac and pressor effects, by reducing metabolism. As a largely specific alpha adrenergic drug, with very weak beta agonism, there is little direct cardiac effect. However, in higher doses, there can be increases in both systolic and diastolic blood pressure and a reflex bradycardia. As an adrenergic agonist there is the potential to interact with other sympathomimetic drugs. In overdose phenylephrine can cause hypertension, headaches seizures tachycardia, and vomiting. There has been no evidence from carcinogenicity studies in rodents of any enhanced cancer risk over prolonged exposure.
The delegates' reasons for the final decision to exempt from the proposed Appendix C entries, teeth whitening preparations containing more than18 per cent of carbamide peroxide and more than 6 per cent of hydrogen peroxide manufactured for and supplied solely by registered dental practitioners as part of their dental practice, comprise of the following.
During studies of the opioidal control of GH secretion several analogs of met-enkephalin were found to be potent GH secretagogs. Among them were GH-releasing peptide-6 (GHRP-6), and hexarelin (His-D2MeTRP-Ala-Trp-DPhe-Lys-NH2) (Laron, 1995). They act via a receptor unrelated to that of GHRH (Howard et al., 1996). The potent biologic action of the GHRPs and the identification of a specific receptor suggested the existence of a natural ligand.

Before the discovery of ghrelin, synthetic GH secretagogs were available. Several studies investigated the effects of these substances on human sleep. Oral administration of the GH secretagog MK-677 for 1 week prompts a distinct sleep-promoting effect in healthy young male volunteers, whereas a weak effect is observed in elderly subjects. This study shows that oral administration of a peptide is capable of promoting sleep. After repetitive intravenous administration of GH-releasing peptide 6 (GHRP-6), non-REM sleep stage 2 increases. Similar to the effects of ghrelin in male subjects GH, ACTH, and cortisol are elevated. In a set of studies, the intranasal, oral, and sublingual administration of GHRP-6 was tested. By these routes of administration the effects of the peptide on the sleep EEG and on hormone secretion are less distinct and partly different from those after intravenous injection. In contrast to the sleep-promoting effects of GHRP-6 and ghrelin, hexarelin prompts a decrease of SWS, whereas the pattern of endocrine effects after hexarelin resemble the endocrine changes after ghrelin and GHRP-6 in that there is a marked stimulation of GH. The decrease of SWS after hexarelin may be related to negative feedback inhibition of endogenous GHRH. After a single dose of GHRP-2 during the third period of REM sleep, sleep remains unchanged. The lack of effects in this study may be related to the method that uses only a single injection of the substance.


First of all CARDARINE is is a PPARδ agonist and NOT a SARM. However they do work in similar ways. Cardarine is the ULTIMATE endurance solution, so bad WADA even has GW 501516 on their list of banned substances due to it's insane competitive edge. Expect great levels of intensity, forget about rest times, and break plateaus like never before. Some advantages of Cardarine: See results on first dose, Shred unnatural levels of fat without going catabolic, can be stacked with anything, Increase in Muscle Growth and Endurance. GW-501516 is really the jack of all trades for those experienced researchers.
GHRP-6 directly stimulates the anterior pituitary gland which subsequently leads to an increase in the release of growth hormones in the body. As GHRP-6 directly affects the feedback loop which triggers changes in inhibition of the release of Growth Hormones, it can be used to restore the natural manufacturing of the Growth Hormone if natural secretion has been impaired because of long term artificial use. GHRP-6 also reportedly has an impact on our nervous system. They are potentially capable of protecting neurons and increasing the strength of a person. The functioning of GHRP-6 is strikingly similar to the working of several steroids in the DHT family. 
As an athlete, you can also increase your dosage cycle for a period of 12 to 16 weeks at a time, to maximize your gains. Do so gradually if you opt to go this route. Make sure you increase your daily dosage (1 to 2 doses per day, etc.) gradually. Start off with lower dosage levels as well, and see how it interacts with your body. You don’t want to experience withdrawal, nor do you want to experience negative side effects when using Ipamorelin for longer dosage cycles. So, make sure you monitor your progress, see how you feel as you go, and make notes if/when you do experience negative side effects, so you can balance down to the proper dosage levels.

Mod GRF 1-29 and CJC-1295 are still being researched. As such, they are not yet medically utilized or approved. Though some firm protocols for the use of these peptides have been developed, the dosage of the compound is not yet medically confirmed. In a study conducted by researchers on 21 to 61 year-old subjects, it was found that depending on the dose, the concentrations of the growth hormone increased to up to 10 times for at least 6 days. Also, the concentration of IGF-1 increased to up to 3 times for 9 to 11 days.
Dosing will ordinarily be at least twice per day and preferably 3x/day for best effect, taken at least 30-60 minutes before a meal and at a time of non-elevated blood sugar (in other words, after blood sugar has had time to fall since the most recent meal.) The amount taken generally will be from 50-300 mcg at a time. When using a GHRH along with GHRP-6, dosing should be reduced to 50-100 mcg at a time.

Phenylephrine is a direct alpha-1 adrenergic agonist, with weak alpha-2 adrenergic agonist activity. It also has very weak beta-adrenergic effects, but at therapeutic doses there are no significant stimulating beta-1 adrenergic effects on the heart, or on the bronchial airways, or on peripheral blood vessels. This contrasts with pseudoephedrine, which has greater beta-adrenergic activity. The effect on the alpha-adrenergic receptors leads to local vasoconstriction and shrinking of mucous membranes. There is no anti-histamine effect. The drug is readily and completely absorbed following oral administration, undergoing extensive first pass metabolism in the intestinal wall and in the liver leading to some variability in individual pharmacokinetics. Nasal decongestion is apparent within 15 to 20 minutes and persists for up to 4 hours (AHFS 2007).
Results: After a single injection of CJC 1295, there were dose dependent increases in mean plasma GH concentrations by 2- to 10-fold for 6 d or more and in mean plasma IGF-I concentrations by 1.5- to 3-fold for 9–11 d. The estimated half-life of CJC 1295 was 5.8–8.1 d. After multiple CJC 1295 doses, mean IGF-I levels remained above baseline for up to 28 d. No serious adverse reactions were reported.

IGF-1 (Insulin-like growth factor) and MGF (Mechano-growth factor) are the peptides that help with insulin-like growth of muscles. In the case of mechano growth factor, it helps stimulate the recovery of damaged muscle tissue and activate satellite cells to produce more muscle tissue. MGF should only be dosed post workout and even on recovery days to utilize the full muscle building effects.

The discovery of the role of Tβ4 in the process of immune regulation has lead to its use as a valuable therapeutic agent. Tβ4 has been used in the treatment of HIV, AIDS, Influenza, colds, and various infections. It has been utilized in the management of various inflammatory conditions, as well as part of treatment following heart attack due to its cardio and neuroprotective effects.
Although the history of some of the foremost biomedical discoveries is permeated by serendipity,4 we deem that the well-established pivotal role of the GH/insulin-like growth factor-1 (IGF-1) axis for cardiomyocyte physiology, and the subtle alterations of this axis within the pathogenicity of dilated cardiomyopathy (DCM) and left ventricular (LV) dysfunction, ignited the idea of assessing the potentiality of GHRP to alleviate cardiac pathologies.5 It was far to be anticipated on those early days, however, that the GHRP-mediated cardiotropic and cytoprotective effects are superior to those shown by the exogenous administration of GH and are not shared by GH-releasing hormone (GHRH) and that, importantly, GHRPs exert their pharmacological actions via GH-independent pathways that obviously represented another turning point in this history.3

The DAC technology in the CJC-1295 enables the compound to bind itself covalently with any circulating albumin, after it has been administered through a subcutaneous injection. However, the reason why the half-life could be extended from a few minutes to several days is more profound. The reactive group in the CJC-1295 binds to a peptide through bioconjugation. The peptide then finds a neucleophilic unit within the blood and reacts with it in order to create a firmer bond.


While GHRP-6 is capable of inducing large increases in GH production when used alone, a given dose will show markedly more effect what a GHRH (growth hormone releasing hormone) peptide is taken at the same time. Alternately, when combining a GHRH with GHRP-6, only about half or a third as much GHRP-6 is needed to obtain the same increase in GH production.
Mod GRF 1-29 and CJC-1295 are still being researched. As such, they are not yet medically utilized or approved. Though some firm protocols for the use of these peptides have been developed, the dosage of the compound is not yet medically confirmed. In a study conducted by researchers on 21 to 61 year-old subjects, it was found that depending on the dose, the concentrations of the growth hormone increased to up to 10 times for at least 6 days. Also, the concentration of IGF-1 increased to up to 3 times for 9 to 11 days.
A SARM (an acronym for "Selective Androgen Receptor Modulator") is a drug that is chemically similar to anabolic steroids but with reduced androgenic properties. The main advantages SARMs have over anabolic steroids are androgen-receptor specificity, tissue selectivity, and reduced side effects. SARMs also have the ability to differentiate between anabolic and androgenic activities, whereas steroids do not.
High testosterone at this stage will accelerate the process. The SARMs are not testosterone, and don’t get metabolised into DHT (nor estradiol). The SARMs selectively bind to the androgen receptor in muscle and bone and amplify the effect of testosterone and DHT there, while not amplifying the effect on other tissue ie skin, prostate. However, through inheritance, if you have hair androgen receptors that are similar to muscle/bone androgen receptors, then SARMs can amplify the androgen message in the hair follicles, and if the inherited androgen sensitivity is activated, it could lead to accelerated male pattern baldness. This is a very rare variation, and while possible, is uncommon. There are no tests available to determine SARMs effect on your hair follicles, nor to determine when your genetic androgen sensitivity in hair follicles will activate.
Male pattern baldness is genetically switched on at an age that varies very widely (some men in their twenties, some men never – look at the onset in males in your family). When the genetically inherited tendency turns on, then testosterone and it’s stronger (but less concentrated) metabolite, dihydrotestosterone, trigger the slow death of the hair follicles on the scalp in a male baldness pattern.
Used for muscle building, weight loss and anti-aging purposes, this is a very powerful peptide for promoting growth hormone release. GHRP-6 also helps in fighting inflammation and boosting recovery. Some professional bodybuilders are believed to use it together with steroids for greater potency. The peptide not only stimulates the pituitary to produce growth hormone, but also suppresses somatostatin which could impede release.
The best way to summarise how well SARMs (and peptides for that matter) work is to point out that they have been banned by WADA (the world anti-doping authority) for competitive sports because they give an unfair advantage to athletes. Luckily they are legal to purchase so if Sarms can do that for athletes imagine how much they can help ordinary folk.
In 2005, we undertook a porcine model of AMI via left circumflex artery occlusion for 1 hour followed by a 72-hour reperfusion period. GHRP-6 rescued ischemic myocardium from death for over 70% of the area at risk (Figure 3), and that in addition to enhance survival signaling pathways/gene expression of the PI-3K, AKT1, and BCL2 pathways, GHRP-6 decreased reactive oxygen species (ROS) spillover, the inflammatory marker CRP, and preserved the antioxidant defenses.45 These antioxidant and anti-inflammatory properties have also been attributed to GHRP-2 when its antiatherogenic potential was examined in ApoE(−/−) mice so that 12/15-lipoxygenase, interferon gamma, and macrophage migration inhibitory factor (MMF) gene expression were accounted. Furthermore, in cultured aortic smooth muscle cells, GHRP-2 prevented the generation of peroxides, the downregulation of IGF-1 receptor, and the commitment of apoptosis.46
Your level of physical activity also affects IGF-1, and heavy weight training for your legs is a particularly potent way to increase it. Some studies suggest that the effects of the popular anti-aging supplement DHEA actually arise due to this same type of increase in IGF-1 in the body that occurs with with weight training (so you choose: heavy barbell squats or a bottle of DHEA from the drugstore).
Now, you may have heard many bodybuilders saying that when you take GHRP-6 that they get a huge and very intense increase in appetite, about 20 mins after the initial injection. Well, this is caused by the GHRP-6 antagonising the peptide Ghrelin, it mimics it, but, in reality, it actually fights against it causing the signal for gastric emptying and hunger. Ghrelin is what many believes causes obesity, and insulin resistance amongst other things, and I believe this is one way by which GHRP-6 may help reduce fat, by fighting against it. However, there is always a but, if you take more than 150mcg the effects of the gastric emptying can be so strong that you may have the urge to severely stuff yourself with food, so if you're on a bulking cycle this is a great side effect, and, considering the price, it's a very cost-effective one. Therefore, during a bulking run, I rate this as the number one aid in increasing appetite, as you also get very a good anabolic effect and increased strength.
So… now we get down to the individual peptides themselves. I will not go into length with a profile for each one, but instead I will provide two charts that should help in understanding which peptides are GHRH’s and which ones are GHRP’s. Of course, IGF and MGF have their own respective spots but do not have the synergy when combined like GHRP and GHRH.
Growth Hormone Releasing Peptide 6 ( GHRP-6) is a peptide which substantially activates the pituitary gland into releasing high levels of growth hormone for a few hours. The increase in growth hormone comes from your own body, not synthetic growth hormones which can suppress your natural production. GHRP 6 is a first generation GHRP and has a few side effects which could be annoying.
I weigh 215 and i have no idea what my bodyfat is, but its pretty high and not where i want it. Im currently in the middle of a strength phase, training 4 days a week Westside style. Im in the middle of week three of that, so im gonna finish my 8 week phase, training that way and see what these peps do. I weigh and measure everything i eat and keep up with it on my phone my fitness pal. I know exactly how many calories i need everyday. Im going to keep my calories at maintenance and see what happens. Hopefully I can keep up with this and let you guys know what kind of results i am getting.
The consumption of such altered compounds may have severe consequences on the user's body and it is critical that they avoid such scenarios. The authorities need to grab the perpetrators responsible for the peddling of these illegal drugs in the market and regulate the black market. Given the many advantages this drug has for the human body and its potential as the all-round supplement, the authorities need to encourage the research and development agencies working on this drugs development. The emphasis should be on making it safer, more side-effect friendly and more compatible to mixing with other anabolic steroids.
For increasing GH levels, GHRP-6 is less effective in the presence of high blood glucose levels or high somatostatin levels, which result from high IGF-1 levels. For this reason, for best effect GHRP-6 should be taken while blood sugar is relatively low, for example about 30-60 minutes before a meal. GHRP-6 will have reduced effect if GH is being taken by injection, because GH increases IGF-1. Where GH use is limited to no more than about 14 IU per week, simultaneous GHRP-6 use probably still will increase GH somewhat further, but if GH use is greater than this then likely GHRP-6 injections will do little to nothing towards increasing GH levels any further.
The delegates made an interim decision to include teeth whitening preparations containing more than 18 per cent of carbamide peroxide and more than 6 per cent (20 volume) of hydrogen peroxide in Appendix C. The delegates also decided to exempt from the proposed Appendix C entry teeth whitening preparations containing 18 per cent or less of carbamide peroxide and 6 per cent or less of hydrogen peroxide manufactured and supplied solely for direct in-clinic use by registered dental practitioners as part of their dental practice. The proposed implementation date for this decision was 1 May 2013.

(a) Representative image of “nipple” in which, above the cartilage and the perichondrium, there is a prominent accumulation of extracellular matrix. (b) Representative image of the effect induced by the GHRP-6 intervention. Note the reduction of extracellular matrix accumulation within the injured area. The “flattening” aspect is indicated by the solid line arrow. The dotted arrows indicate that the elevation within the center of the scar is similar to the adjacent intact skin. Images suggest that GHRP-6 reduced the local hypercellularity associated with the cartilage cells response. H/E 10x magnification.

Since CD36 is implicated in angiogenesis regulation, special attention was addressed to the population of neovessels as to their general morphology. By routine staining, we ascertained that GHRP-6 treatment did not reduce the number of vessels, which also exhibited normal structure, organization, and distribution. Furthermore, CD31 expression was detected in all these vascular structures suggesting mature angiogenesis. Conclusively, GHRP-6 administration did not hinder wound angiogenesis in any respect (Figure 3(a)), as compared to placebo-treated wounds (Figure 3(b)). These histological findings support the scoring on the ECM maturation and the quantification of inflammatory cells across the wounds (Table 2).
After repeated intravenous (i.v.) boluses of growth hormone-releasing peptide-6 (GHRP-6) we found recently increases of growth hormone (GH), corticotropin (ACTH) and cortisol levels and of the amount of stage 2 sleep. In clinical use, oral (p.o.), intranasal (i.n.) and sublingual (s.l.) routes of administration have advantages over i.v. administration. We compared the sleep-endocrine effects of 300 microg/kg of body weight (b.w.) GHRP-6 in enteric-coated capsules given p.o. at 21.00 h and of 30 microg/kg GHRP-6 i.n. or 30 microg/kg GHRP-6 sl. given at 22.45 h in normal young male controls with placebo conditions. After GHRP-6 p.o. secretion of GH, ACTH and cortisol remained unchanged. The only effect of GHRP-6 s.l. was a trend toward an increase in GH in the first half of the night. GHRP-6 i.n. prompted a significant increase in GH concentration during the total night and a trend toward an increase in ACTH secretion during the first half of the night, whereas cortisol secretion remained unchanged. Furthermore, after GHRP-6 i.n., sleep stage 2 increased in the second half of the night by trend, and spectral analysis of total night non-rapid eye movement (REM) sleep revealed a decrease of delta power by trend. In contrast sleep stage 2 decreased during the second half of the night after GHRP-6 p.o. Our data demonstrate that GHRP-6 is capable of modulating GH and ACTH secretion as well as sleep. However, the effects depend upon dosage, duration and route of administration.
