The potent biologic effects of GHRPs and the identification of the GHS-R suggested the existence of a natural ligand for the receptor that is involved in the physiologic regulation of GH secretion. The acylated peptide ghrelin, produced and secreted into the circulation from the stomach, is this ligand (Fig. 7-22). The effects of ghrelin on GH secretion in humans are identical to or more potent than those of the non-natural GHRPs (see Fig. 7-20). In addition, ghrelin acutely increases circulating PRL, ACTH, cortisol, and aldosterone levels. There is debate con­cerning the extent and localization of ghrelin expression in the brain that must be resolved before the implications of gastric-derived ghrelin in the regulation of pituitary hormone secretion are fully understood. Furthermore, post-translational processing of pro-ghrelin gives rise to a second neuropeptide, obestatin, which may also have functional roles in activity of the GH/IGF-1 axis and metabolism. A proposed role for pro-ghrelin peptides in appetite and the regulation of food intake is discussed in Chapter 35.

Healthy male Wistar rats (250–270 g) were purchased from the National Center for Animal Breeding (CENPALAB, Havana, Cuba). Animals were individually housed at the animals’ facility of the Center for Genetic Engineering and Biotechnology, Havana, Cuba, and maintained under controlled environmental conditions and light cycles (12/12 hrs). Rats were fed with standard laboratory rodent’s chow under no restriction. Following an acclimation week, the dorsum of the rats was conditioned to receive two controlled full-thickness wounds, under sodium pentobarbital (30 mg/kg) anesthesia. The cuts were generated with disposable 6 mm diameter punch biotomes (Acuderm, Ft. Lauderdale, USA). Two independent experiments were performed using the above described wound model. Thus, 10 rats ( wounds) were used for either GHRP-6 formulation or vehicle (1% CMC) groups in each experiment. Upon wounds induction the rats were randomly assigned to either group. The wounds were cleansed daily with saline, their contours traced on transparent plastic sheets and treated accordingly. Treatments were topically applied twice a day at the same hours during four days. Wounds closure dynamic was measured by planimetric analysis as described previously [16] using the ImageJ software, version 1.46r. Since the GHRP-6 intervention increased the rate of closure, the animals were terminated by anesthesia overdose on day five after wounding. Ulcers and a surrounding margin of intact skin (~5 mm) were collected and hemisectioned. One hemisection was preserved in RNA Later solution for further gene expression studies. The other hemisection was fixed in 10% buffered formalin, paraffin embedded, and 5-μm sectioned. The specimens were stained with hematoxylin/eosin (H/E) and Mallory trichrome to examine collagen deposit. Other slides were destined for immunohistochemistry (as described below).
By increasing our own growth hormone levels (which normally decrease as we age), there is an increase in protein synthesis which subsequently stimulates muscle growth.  It leads to an increase in muscle mass, an increase in fat metabolism (fat loss), and increase in physical strength.  It is also helpful in skin ageing, and effective in reducing wrinkles.

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].
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.
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 number of infiltrating immunoinflammatory cells and neoformed vessels was determined within the granulation tissue of each wound. For this purpose, images of at least 10 microscopic fields (10–20x magnification) were captured and photographed so that mature vascular structures and infiltrated mononuclear cells were counted along with the assistance of the ImageJ processing system, version 1.46r.
CJC-1295 is basically a peptide hormone that acts similar to growth hormone releasing hormones (GHRH). Invented by a Canadian biotechnology company called ConjuChem, it is beneficial to athletes because it can bioconjugate with circulating albumin and increase the time it can be used for medical purposes. It achieves this by preventing degradation of its amino acids. With a single dose, it can remain in the body for quite a few days and can cause the growth hormone to be released many times per day. This reduces the frequency of injections needed.

I have been using sermorelin (bioidentical growth hormone releasing hormone) for 2 months now to help heal a nasty right quad tendon rupture suffered the end of December. I’m 52 years old with 7% bodyfat and am a lifetime strength trainer and former high level bike racer. 2 months ago, in spite of months of religious rehab, I couldn’t do a single right leg bench stepup. Yesterday I was doing 20lb DB’s for repeated sets of 15. I get complete blood panels every 6 months, and my last labs in May showed my IGF-1 levels off the reference range low. I get my next bloods in a couple of weeks. I was initially afraid to try this hormone due to the cancer implications, and I didn’t need it to be lean and fit, but I was desperate and for my injury recovery, and it has made a significant difference. Plus, I believed supplementing the releasing hormone vs, IGF-1 limits the possibility of increasing the levels too much, as well as causing a negative feedback loop. By the way, I also tried TB-500 previous to the sermorelin, and it seemed to make some other achy joints in the gym go away, but didn’t seem to help the quad injury.
Depending on the intended use, and your desired results, the dosage levels are going to vary from person to person as well. So, keep this in mind when trying to determine how great the results are actually going to be when you are using Ipamorelin. So, what exactly can you expect when using this supplement? Some things you will see, for every user is:
Despite the controversies, some scientists continued with additional studies and again proved IGF-1 to actually prolong life…at least in worms.  Then, in 2001, scientists discovered that the use of IGF-1 resulted in a proliferation of cancer cells, especially throughout the breast and colon, and a 2012 study found that both too much or too little IGF-1 could contribute to dying from cancer; implying that IGF-1 actually helped patients with terminal cancer live longer.
But let’s say you’ve already implemented the IGF-1 boosting strategies of adequate calories, sufficient protein, weight training, plenty of sleep, smart supplementation, mineral intake and alcohol moderation. Should you take the next step, wander into an anti-aging clinic, find an online pharmacy, lurk in the depths of bodybuilding forums, and begin IGF-1 injections?
Boasting similar structure as CJC-1295, sermorelin is commonly used for anti-aging purposes. But it is also considered useful for muscle building. It accounts for 29 amino acids of the 44 that make up growth hormone releasing hormones. This peptide is very potent for improving HGH levels, as shown in studies. It was observed that the 1-29 amino acid chain is mainly responsible for the ability of GHRH to stimulate release of growth hormone by the pituitary. However, sermorelin has very short half-life of about 10 minutes or less.
Mostly, these peptides are sold as lyophilized powder in 2mg containers. Bacteriostatic water should be mixed with the powder in order to reconstitute it. To make the dosage of 100mcg per injection, 2ml bacteriostatic water should be mixed into 2mg of lyophilized powder. This reconstituted mixture should be then injected inside the muscles or under the skin. The mixture should be kept under refrigeration at all times otherwise it will degenerate and will not be effective anymore.
CJC-1295 and Mod GRF 1-29 are administered in micrograms (mcg) rather than milligrams (mg) – the unit of administration of other steroids and performance-enhancing drugs. It has also been found that a 100mcg dose is enough to fully saturate the receptors in the anterior pituitary. This is called the saturation dose. After a dose of 100mcg has been administered, the subsequent dosages will achieve only half the effect.
The most important initial historical time points in the development of the enlarging ghrelin system were 1973, 1976, 1982, 1984, 1990, 1996, 1998, and 1999 during which the following sequentially occurred: isolation of somatostatin; discovery of unnatural growth-hormone-releasing peptides (GHRPs); isolation of growth-hormone-releasing hormone (GHRH); hypothesis of a new natural GHRP different from GHRH; GHRP+GHRH synergism in humans; discovery of the growth hormone secretagogue GHS/GHRP receptor; cloning of the receptor; isolation; and identification of the new natural endogenous GHRP ghrelin.1
The wounds were monitored and followed from day 14 until day 30 after wounding so as to detect the nodular firm consistency that precedes the clinical exuberance. The animals remained in observation for another 20 days after GHRP-6 administration had been completed. The incidence of firm, protruded nodules with nipple-like appearance arising in resurfaced wounds was registered weekly until day 50. After euthanasia (anesthesia overdose), the samples were collected in block, longitudinally bisected along the largest point of nodular growth. One hemisection was nitrogen frozen for additional studies and the other one was fixed in 10% neutral buffered formaldehyde and processed for histology. Five-micrometer sections were stained with H/E staining. Scar overgrowth was measured using the previously described scar elevation index (SEI) based on the cross-sectional scar area to the area of tissue excised to induce the wound [21]. Blinded researchers measured the sections using the ImageJ software package, version 1.46r.
Dose-wise, studies have shown that the body will release a decent amount of natural GH with a dose of only 100mcg (termed the SATURATION DOSE) injected subcutaneously or intramuscularly. Higher doses can be used up to 300-500mcg in a single shot but double the dose does not mean double the GH; the amount of release is not directly proportional and the ratio of release diminishes as the dose climbs. I personally find 250mcg to be my sweet spot and doesn’t cost too much to run a short cycle at that dose.
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.
GHRH (Growth Hormone Releasing Hormones) cause the body to secrete a small amount of growth hormone. Depending upon the peptide, there can be short to long secreting times. Also, be aware that with most peptides there is a saturation dose (normally around 100mcg at a time). This means that going beyond the saturation dose will not produce an increase in growth hormone release. Experienced peptide users have indicated that saturation doses may actually be higher than 100mcg. However, this seems to depend on the purity of the peptides, and perhaps even based on the individual person themselves. In general, due to the nature of peptides, a lot of information has become anecdotal in nature rather than scientific.

Four submissions suggested an Appendix C entry for hydrogen peroxide and carbamide peroxide with various cut-off values. Three of these submissions supported the current Schedule 5 and Schedule 6 entries. One submission supported amending the Schedule 5 entry to capture all teeth whitening products of 3 per cent or more of hydrogen peroxide and 9 per cent or more of carbamide peroxide.
The key to your exercise recovery rests firmly on how well you behave between the sheets. No, not like that, sleep is a time when your muscles repair and a big catalyst for this is the recovery power lies in your hormones, namely GH. Research in the journal Neuroendocrinology found GHRP6 supplementation improves the quality, but not duration, of your sleep. And better sleep is a formidable gladiator in your armoury if you want to make your muscles more maximus, plus it can improve your ability to heal from injury, but it’s not all gravy. Some users do report feeling painfully ravenous, preventing them from getting quality kip. If this is the case then have a big feast after a dose, then hit the hay. Good cop for anyone looking to build, bad cop for anyone looking to lean up.
