Growth hormone-releasing peptides (GHRPs) constitute a group of small synthetic peptides that stimulate the growth hormone secretion and the downstream axis activity. Mounting evidences since the early 1980s delineated unexpected pharmacological cardioprotective and cytoprotective properties for the GHRPs. However, despite intense basic pharmacological research, alternatives to prevent cell and tissue demise before lethal insults have remained as an empty niche in the clinical armamentarium. Here, we have rigorously reviewed the investigational development of GHRPs and their clinical niching perspectives.
Just as the name suggests, GHRH helps to stimulate secretion of growth hormone. The duration of secretion induced will depend on the specific type of peptide that you use. An important thing to note here is that these substances are effective only to a limit. Exceeding the saturation dose, which may vary between individuals, will not improve the amount of HGH that is secreted. Below are a few peptides that fall in the GHRH group.
The ACMS recommended that Growth Hormone Releasing Hormones (GHRHs), Growth Hormone Secretagogues (GHSs), Growth Hormone Releasing Peptides (GHRPs) as well as new individual substance entries for CJC-1295, ipamorelin, pralmorelin (Growth Hormone Releasing Peptide-2), Growth Hormone Releasing Peptide-6, hexarelin and AOD-9604 be included in Schedule 4.
For example, studies have shown that people deficient in IGF-1 have an increased chance of dying from a heart attack. This is because IGF-1 prevents the death of heart cells and offers protection to heart cells when the cells are stressed, such as during a heart attack or long amount of time without oxygen. IGF-1 has a similar protective effect on brain cells.
Administration of peptides is normally subcutaneous or intramuscular. Peptides come as a fine white and delicate powder that must be reconstituted with bacteriostatic water or medical grade saline. An insulin syringe should always be used to administer the dose. When targeting muscles, look for a place where the layer of skin and fat are lean. Mixing two peptides in the same syringe is totally fine but I personally would advise not drawing/mixing doses and storing pins for future use.
The search strategy was based on the PubMed/MEDLINE electronic databases including original research and review articles. The search was progressively date escalated from 1980 and included articles in English only. The search terms were as follows: growth hormone secretagogues (GHS), GHRP, growth hormone secretagogue receptor (GHS-R), CD36, cardiac ischemia/reperfusion, cardiac stunning, heart failure, cytoprotection, and cardioprotection.
In rat stomach, a second type of ghrelin peptide has been purified and identified as des-Gln14-ghrelin (). Except for the deletion of Gln14, des-Gln14-ghrelin is identical to ghrelin, even retaining the n-octanoic acid modification. Des-Gln14-ghrelin has the same potency of activities with that of ghrelin. The deletion of Gln14 in des-Gln14-ghrelin arises due to the usage of a CAG codon to encode Gin, which results in its recognition as a splicing signal. Thus, two types of active ghrelin peptide are produced in rat stomach: ghrelin and des-Gln14-ghrelin. However, des-Gln14-ghrelin is only present in low amounts in the stomach, indicating that ghrelin is the major active form. In addition, n-decenoyl (C10:l)-modified ghrelin exists in the stomach in small amounts.
It is here that Growth Hormone Releasing Peptide 6, or Growth Hormone Releasing Hexapeptide comes into the picture. Also called as GHRP-6, it is a synthetic met-enkephalin analog. It includes unnatural D amino acids. It is instrumental in releasing growth hormone that helps in muscle recovery, strengthing of joints and tendons, and fat loss. It is distinct from Growth Hormone Releasing Hormone or GHRH which causes a higher amount of growth hormone to be secreted during the body normal secretion time. GHRP-6 on the other time will target a pulse and force the pituitary to release the growth hormone that is stored there. It helps a particular muscle group to achieve maximum growth.

Exercise and sports have, in recent times gained the credit it is due. Not only are these sports a testament to the fortitude of the athletes, but they are also a science in themselves. Each sport has different exercise regimes and different dietary requirements. While some athletes face the same environment in each competition, there are those who have to face a different environment every time they compete. What remains constant however is the importance of growth hormone and the effect it has on the athlete’s body.

But for maintenance of adequate and natural IGF-1 and growth hormone, and to achieve that sweet spot of not becoming to pro-growth while also not becoming a weak, muscle-less noodle, that sweet spot of producing adequate insulin without producing too much, and that sweet spot of increasing cellular repair without letting cellular division get “out of control”, I have indeed been implementing three specific strategies: my IGF-1 “trilogy”.
GH-releasing peptides (GHRPs) are synthetic peptides that like GHRH act directly on pituitary somatotrophs to stimulate GH release. Growth hormone (GH) release is stimulated by a variety of synthetic secretagogues, of which growth hormone-releasing hexapeptide (GHRP-6) has been most thoroughly studied; it is thought to have actions at both pituitary and hypothalamic site.
There is the potential for the side effects associated with use of growth hormone when growth hormone secretagogues are used, particularly if the use is not under medical supervision. There are limited data on the safety of intravenous and subcutaneous use of AOD-9604 and on the long-term oral use of AOD-9604 in doses in excess of those used in clinical trials.
Hunger increases: All GHRP’s will increase hunger, and GHRP-6 is very potent when it comes to this undesired effect. This can become annoying, and some users complain about waking up at night, or in the morning feeling starved. Logically, those looking to boost appetite, might appreciate this side effect, but for most users (who usually expect to lose fat while on) it becomes aggravating.
On the legality issue, peptides are always classed as ‘research chemicals’, not intended for human use. This is because anything that was intended for human use and especially compounds that are meant to be injected, would have to undergo intensive human research and testing, taking many years before approval. They are classed as research chemicals for use in lab experiments ONLY, which is why on the forums you will see guys talking about injecting their rat/rabbits/guinea pigs with peptides, etc., not specifically saying they are injecting themselves, as a get out clause if any legal repercussions came about.
Increasing HGH release levels in your body naturally. It sounds too good to be true, but what if you could achieve just that by using a supplement? Using Ipamorelin alongside your exercise and diet regimen is going to help you achieve said goal. No two users are alike. For athletes or those who workout religiously, you might experience greater results than an individual who is overweight and just getting back into the gym after 10 years. So, take it with a grain of salt when detailing the results below. Dosage, your body composition, and other factors will play a role in the results you can expect to see when you incorporate Ipamorelin.

Hexarelin is a peptide that is derived from GHRP 6, but has been optimized to enhance its metabolic stability. Like the other GHSs, hexarelin increases hGH production, resulting in increased muscle mass, bone density, skin elasticity, and decreased body fat. Unlike the other GHRPs, however, hexarelin does not lead to a substantial increase in ghrelin and therefore does not cause the same appetite stimulation. This peptide has been further promoted for its cardioprotective and regenerative action as well. Hexarelin would be an ideal choice for those looking to benefit from increased growth hormone without appetite stimulation.

Peptides offer a number of health benefits and bodybuilding is a field where these peptides are useful as well. When it comes to bodybuilding and sports performance, peptides help increase number of muscle cells. They even help to reverse the generic outlook along with allowing you to increase the muscle density. Use of peptides simply means that you will be able to develop muscle density you dream of.

Peptide therapy encompasses numerous different drugs with varied effects, ranging from immune modulation and tissue repair to fat loss and muscle building. Our center has seen very positive results in patients with CFS, Hashimoto’s thyroiditis, Lyme disease, and fibromyalgia, among other conditions. Ask your physician or speak to a patient representative at (877) 508-1177 to find out if peptide therapy is right for you.
Just as the name suggests, GHRH helps to stimulate secretion of growth hormone. The duration of secretion induced will depend on the specific type of peptide that you use.

Exceeding the saturation dose, which may vary between individuals, will not improve the amount of HGH that is secreted. Below are a few peptides that fall in the GHRH group.
An intact hypothalamic-pituitary axis is required to achieve the maximal effect of GHSs on GH release. GHRH and somatostatin both influence the action of GHSs, augmenting and diminishing the magnitude of the GH pulse, respectively. When GHRH is administered in combination with GHSs, the effect is synergistic, the magnitude of the GH pulse being greater than that obtained from the sum of the two agents administered separately. GHS stimulation of GH secretion requires the presence of GHRH. In members of a family with a homozygous inactivating mutation of the GHRH receptor, hexarelin was ineffective in stimulating GH release. In addition, children who are GH-deficient as a result of pituitary stalk transsection are unresponsive to GHSs. Thus, somatotroph exposure to GHRH is necessary for GHSs to exert their action.
One submission was received, which did not support the delegate's interim decision, as available data support that the fixed dose paracetamol/caffeine combination product provides clinically meaningful efficacy over paracetamol alone; has an excellent safety profile; a very low risk of nephrotoxicity, toxicity in overdose, misuse, abuse or illicit use; and a highly favourable risk/benefit profile.

Drug discovery is an uncertain ground in which disappointments and rewards are encountered. Most of those who have been involved in GHRP research have enjoyed clear-cut data, which in most of the cases are all in with very few outs. Exceptionally, a pharmacologically active agent appears to be endowed with such a variety of useful properties as to make it highly drugable. The fact that synthetic GHRPs bind at least two different and biologically significant receptors that seem not to be redundant in nature and are largely represented in most organs and tissues broadens their biological activities and increases their pharmacological potentialities. This suggests that GHRPs may stimulate multiple cells and simultaneously trigger different signaling pathways. The information gathered so far in terms of the molecular cytoprotective mechanism of GHRPs is inconclusive and fragmentary, which has become difficult to disclose the hidden facts behind their biological effects. Nevertheless, it is reasonable that these molecules share the ability to knock life-sensitive pathways and restore critical organelle physiology at very proximal levels. Beyond their ability to enhance the survival of a diversity of cells and tissues before adverse episodes, GHRP members exert an agonistic effect of the GH/IGF-1 axis, promoting anabolia and deterring catabolism and sarcopenia.

Myocardial ischemia/reperfusion damage entails multiple molecular and biochemical mechanisms that each alone is sufficiently injurious to disturb an organ whose mechanical performance is dependent upon the stability of ionic/electrical pumps. Oxidative stress, intracellular calcium overload, pH changes, mitochondrial dysfunction, inflammation, and excessive neurohormones are part of an interactive and self-perpetuating continuum of the myocardial injury cascade (Figure 1). The evidences obtained along the years of experimental screening of the synthetic GHRP suggest that each single member of this family of peptides is able to simultaneously counteract different injurious operators in the myocardial ischemic event.

CJC-1295 is a fast-acting Growth Hormone Releasing Hormone designed to enhance the body’s natural production and release of human growth hormone and Insulin-like Growth Factor 1 (IGF-1). In doing so, CJC-1295 reverses the age-related decline, generates new muscle cells and increases fat loss. Another great trait of CJC-1295 is its ability to promote slow wave sleep, a deep sleep responsible for the highest levels of cell regeneration, muscle growth and memory retention.
Now these artificially manufactured compounds can replicate certain hormones within the human body to signal or trigger certain effects. Whereas GH (a total protein hormone of 191 amino acids), can attach to receptors at multiple sites within the body to influence different effects (say muscle cells, bone cells and fats cells, to name but three), shorter peptides have been isolated to trigger certain effects in a specific area/s. Imagine it’s like having a full tool box which you can mend a whole car with, but then you take certain tools out for different jobs and keep them apart in separate drawers which do specific jobs…sort of.
Paracetamol/caffeine formulations have a long-established safety and efficacy profile over 25 years of use as an open-sale medicine in major markets around the world. The paracetamol/caffeine combination analgesic was registered as a schedule 2 product in Australia and has been marketed since 2010. Since that time no new significant issues or potential risks have been reported.
In 1982, the natural hormone "Growth Hormone Releasing Hormone" (GHRH) was identified after a prolonged search. Soon, researchers discovered that those GH-Releasing Peptides (specifically GHRP-6 & GHRP-2) followed a mode of action which bound them to and was mediated through receptors different from those for GHRH. Furthermore, researches discovered that these GH-Releasing Peptides acted synergistically with the natural hormone Growth Hormone Releasing Hormone (GHRH), which is related to Sermorelin, in both laboratory animals and humans to produce large releases of Growth Hormone. In the 1980s, the first highly potent GH-Releasing peptide, GHRP-6, was developed. Due to a strong GH release response from the the peptide, it became the first member of a class called Growth Hormone secretagogues. GHRP-6 is a hexapeptide composed of 6 amino acids: L-Histidine, D-Tryptophan, L-Alanine, L-Tryptophan, D-Phenylalanine and L-Lysine. The "L" form of an amino acid is the naturally occurring form and often in the nomenclature the "L" is dropped. The "D" form does not occur in nature and is the isomeric form (i.e. mirror image) of the naturally occurring "L" form. GHRP-6 (His-D-Trp-Ala-Trp-D-Phe-Lys-NH2) is composed of both natural and isomeric forms of those 6 amino acids.This sequence provides a signal to the body to begin secreting Growth Hormone release while also blocking Somatostatin, a hormone that inhibits the release of Growth Hormone.

Immunohistochemical determination of CD31 expression (platelet endothelial cell adhesion molecule-1, PECAM-1) was conducted as this is a marker protein of mature vascular endothelium [19]. Sections (5 μm) were mounted on chromalum-coated slides, dewaxed, rehydrated, rinsed, and washed in PBS 1x solution for 30 min. Once endogenous peroxidase was quenched, the specimens were treated with target retrieval solution (Dako) equilibrated at 99°C. Tissue samples were then incubated for 40 min with 1/50 dilution of anti-CD31 antibody (Abcam 28364, USA) in background reducing solution (Dako). The immunohistochemical reactions were carried out using the labelled streptavidin/biotin-horseradish peroxidase conjugate method, according to the manufacturer’s instructions (Dako). The peroxidase reaction was developed with diaminobenzidine and counterstained with hematoxylin.
When using any GHRH, it should always be remembered that positive results cannot be achieved overnight. These compounds act steadily over time, and the best results can be achieved slowly, and with a nutritious diet and a proper exercise regime. Also, these peptides are not sex-specific, so they do not have any androgenic effects. They can be used by women in the same dosages that men do.

Our group has contributed to validate the potential antifibrotic abilities of GHRP-6 in animal models of liver cirrhosis38 and hypertrophic scars,39 in which via a peroxisomal proliferator-activated receptor gamma (PPARγ)-driven cascade, GHRP-6 intervention reduced TGF-β1 and connective tissue growth factor (CTGF) expression, which translated in a dramatic reduction in the accumulation of collagen and other extracellular matrix (ECM) proteins.
200 to 300 mcg is typically the daily dosage which is recommended for the typical Ipamorelin user. It can be taken anytime during the day but is advisable to be used in the morning, as it will help you achieve the best results in such cases. Regardless of when you start your dosage, it is important to ensure you are taking it at the same time each day. And, for new users, it is best to stick to a one-a-day cycle.
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.

I have not used IGF-1 but I have used a stack of Ipamorelin and CJC 1295 no DAC. I did not do any lab tests before, during or after but definitely noticed increased fat loss and better sleep. I was not trying to increase muscle so there was no change to speak of for me. But you are not recommending their use even without IGF-1, is that correct? I do not compete in anything so WADA is not a concern.

Since GHRP-6 influences natural GH release, rules for its administration are similar to those when administering GH itself, i.e. do not have the dose within a 2 hour window after a meal, and/or wait 30 minutes till eating after dosing, due to any endogenous insulin release from the meal possibly stunting the release of natural GH and its uptake by the relevant cells.

I stopped the colostrum and my ” symptoms ” subsided, seems I have a moderately enlarged prostate which doesn’t run in my family on either side, my question is could the colostrum possibly cause the prostate to enlarge due to the igf-1 at a certain age,? due to a possible decline in testosterone, or could the benefits of colostrum outweigh the prostate issue?


The peptide therapy protocols (Amino Acid Analogs) prescribed by TeleWellnessMD providers are also known as secretagogues (pronounced se-creta-gog), a substance that promotes secretion. These amino acid chains communicate with the body to produce or release growth hormone. Hence a secretagogue causes the body’s own natural processes to produce growth hormone. Secretagogues do not act as growth hormones but rather stimulate the pituitary gland to secrete your stored growth hormone. The subcutaneous injection route of growth hormone stimulation is a preferred route to help slow down age and environmental reductions in growth hormone levels.
One of the other uses for GHRP-6 is to kick start your own GH after a cycle, a dose of 200-500mcg 2x a day is sufficient to start your own GH; however, it does not mean your own GH levels will be where they were before you carried out your cycle, this is user dependent. It will certainly be a very useful addition to any hormonal cycles' PCT, as the increased IGF-1 levels it brings will greatly increase the chances of you holding on to any muscle you have gained.
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.

Observation reveals that peptides have become more and more popular in recent years among bodybuilders and those coveting a great body. This trend, perhaps, is influenced by relative difficulty in getting and using anabolic steroids. But what are these substances and are they really legal alternatives to steroids? What benefits do bodybuilders hope to get from using them? We answer these questions and more, including peptide types, in this piece.

Peptides: Are a small chain of amino acids that isn’t quite long enough to be considered a protein. In other words they are the building blocks for protein in the body. They actually have a wide range of functions with the most popular being an increase in growth hormone, increase in recovery (and by default muscle building) and even a natural tan.

Broadly speaking, it’s long been a widespread view that fasting can in many instances provide healthful effects beyond simple fat loss. It’s speculative to say that increased ghrelin levels must be a major cause of such effect (if granting the effect), but it’s entirely consistent with the scientific literature that such elevation of ghrelin levels may have health benefits. Appropriate-dosed and cycled GHRP use may at least partially provide such benefits, particularly with regard to anti-inflammatory and healing effect.

Hypertrophic scarring is a form of abnormal, exuberant healing, locally aggressive, and recurrent cutaneous fibroproliferative condition, characterized by excessive extracellular matrix (ECM) accumulation during the cutaneous healing process. Including keloids and hypertrophic scars (HTS), these aberrant processes lead to esthetically disfiguring scars, patients’ psychological stress, and functional impairment [1]. The cellular and molecular mechanisms underlying the formation of these raised dermal scars are poorly understood. Recent whole genome profiling and proteomic studies have led to the identification of regulatory elements with different expression profiles in HTS and keloid tissues [2]. The limited understanding of the pathophysiology of these processes has led to investigating a broad spectrum of potential antihypertrophic scarring candidates [3].
In more recent years, these data were further substantiated using again the TO-2 hamster DCM biomodel in which GHRP-2 reduced the progression of LV remodeling, dysfunction, and the ensued myocardial fibrosis by an antioxidant mechanism.36 The abovementioned myocardial fibrotic process amelioration reveals an additional potential use for GHRP in an unmet medical need. Chronic treatment with hexarelin in spontaneously hypertensive rats, in addition to decreasing ventricular hypertrophy, diastolic dysfunction, and high blood pressure, significantly reduced cardiac fibrosis by decreasing interstitial and perivascular myocardial collagen deposition and myocardial hydroxyproline content. Mechanistically, hexarelin treatment increased matrix metalloproteinase (MMP)-2 and MMP-9 activities and decreased myocardial mRNA expression of tissue inhibitor of metalloproteinase (TIMP)-1.37
