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.
Unfortunately, as we age, the amount of growth hormone that is produced starts dropping, and into our 40’s it starts dropping off rapidly. This is where GHRP-6 can help a lot, as it mimics ghrelin in the body, which stimulates the ghrelin receptors. When this occurs, a signal is sent to the pituitary gland, increasing GH production. Another benefit of GHRP-6 is that it blocks out a hormone called somatostatin, which is the enemy of HGH secretion. Finally, there is evidence that GHRP-6 can have a positive effect on the nervous system by protecting neurons, giving the user a much higher overall wellness.

During the last 15 years, a plethora of experimental evidence supports the pharmacological benefits of the exogenous administration of synthetic growth hormone-releasing peptides (GHRPs). In parallel to their growth hormone-releasing action, these agents exert cytoprotective effects encompassing cardiac and extracardiac organs [8]. GHRP-6 is a class of peptidyl GH secretagogue, similar to met-enkephalin, that has reproducibly shown antinecrogenic and antiapoptotic properties in multiple experimental scenarios, including ischemia/reperfusion [9–11]. Globally speaking, exogenously administered GHRP-6 has broadly been shown to act as a prosurvival factor for cells and tissues threatened by otherwise lethal insults.
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”.
Both paracetamol and caffeine are regarded as being well tolerated when used at therapeutic doses and there is a low risk of serious expected or serious unexpected adverse events with these products when taken either alone or in combination. Clinical data demonstrate that paracetamol combined with caffeine significantly out performs paracetamol alone. Paracetamol/caffeine formulations are well established globally. Such formulations are marketed in over 90 countries and have been available unscheduled ranging from 14 years to 25 years. Cumulative post-marketing experience to date with the sponsor’s paracetamol/caffeine combination products is estimated to be in excess of 488 million patients and has revealed no adverse safety signals or reasons for concern with the use of this product in an open sale environment.

White male New Zealand rabbits (4.3–4.5 kg) were used in four independent and extemporaneous experiments. Three to four wounds were created on the ventral side of each ear, down to the surface of the cartilage, using a 6 mm diameter punch biotome (Acuderm) as described [20]. For the surgical procedures, rabbits were anesthetized with intramuscular ketamine (60 mg/kg) and xylazine (5 mg/kg). In order to ensure an exuberant scarring, the perichondrium was carefully scrapped with the surgical blade. The wounds were made on each side of the midline, avoiding the central ear artery and the marginal ear veins. In three experiments, rabbits were randomly assigned to either GHRP-6 (400 μg/mL) treatment or 1% CMC placebo gel. The jelly solutions were administered using 1 mL sterile disposable syringes; 250 μL was applied to each wound, which for the group of GHRP-6 represented an actual dose of 100 μg per wound. Treatments were initiated immediately after surgery and continued thereafter until day 30, when most of the wounds had already completed reepithelialization.

Because these peptides are so numerous and variable in structure, their effects are likewise varied and wide-ranging. One class of these peptides are known as growth hormone secretagogues, and cause the secretion of one’s own, natural hGH in the body. These peptides have been shown to be very useful in the treatment of age-related conditions, osteoporosis, obesity, and various chronic inflammatory diseases, and have several advantages over traditional hGH administration.

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.
CJC1295 is a 30 amino acid peptide, which primarily functions as a growth hormone releasing hormone analogue (mimicking the effect of GHRH). It was initially invented to treat deep fat deposits in people, because it is known that having an increase in our own growth hormone levels will target this. It stimulates production of our own growth hormone from the pituitary gland.
The growth hormone-releasing peptide-6 (GHRP-6) is one of several synthetic met-enkephalin analogs that include unnatural D-amino acids. They were developed for their growth hormone (GH) releasing activity, then called GH secretatogues. They lack opioid activity but are potent stimulators of GH release. These secretatogues are distinct from the growth hormone releasing hormone (GHRH or GHRF) in that they share no sequence relation and derive their function through action at a completely different receptor, the ghrelin receptor.
GHRPs bind to two different receptors (GHS-R1a and CD36), which redundantly or independently exert relevant biological effects. GHRPs’ binding to CD36 activates prosurvival pathways such as PI-3K/AKT1, thus reducing cellular death. Furthermore, GHRPs decrease reactive oxygen species (ROS) spillover, enhance the antioxidant defenses, and reduce inflammation. These cytoprotective abilities have been revealed in cardiac, neuronal, gastrointestinal, and hepatic cells, representing a comprehensive spectrum of protection of parenchymal organs. Antifibrotic effects have been attributed to some of the GHRPs by counteracting fibrogenic cytokines. In addition, GHRP family members have shown a potent myotropic effect by promoting anabolia and inhibiting catabolia. Finally, GHRPs exhibit a broad safety profile in preclinical and clinical settings. Despite these fragmented lines incite to envision multiple pharmacological uses for GHRPs, especially as a myocardial reperfusion damage-attenuating candidate, this family of “drugable” peptides awaits for a definitive clinical niche.
Finally, an exciting medical opportunity could be opened for synthetic GHRP to treat the threatening cancer-associated anorexia–cachexia syndrome in advanced-stage cancer patients. Although the mechanistic bases of this syndrome are not fully understood, it represents a major impediment for the course of chemotherapy. In a rodent model of cancer-bearing chemotherapy, GHRP-2 administration increased appetite/food intake and prolonged median survival time, which certainly suggests that GHRP-2 may improve the quality of life of cancer patients by correcting its nutritional and metabolic states.61 These data may also incite to further studies in the search for a potential niche for GHRP to counteract the catabolic states of prolonged critical illness, invasive surgeries, severe burn traumas, etc.

to amend the Standard for the Uniform Scheduling of Medicines and Poisons to include vitamin D, as a single weekly dose of up to 175 micrograms (7000IU) per recommended dose, in Schedule 3 (noting that the wording "per recommended weekly dose" in the interim decision's proposed Schedule 3 entry should have read "per recommended single weekly dose"); and


At the histological analysis, and from a qualitative perspective, these wounds appeared less inflamed and with a higher degree of ECM organization, given by far less fibrin accumulation and thinner and horizontally distributed collagen bundles. Vessels were also aligned with the collagen fibers. Thus, the treatment not only reduced the wound area but also appeared to be associated with differences in the quality of the ECM as the inflammatory infiltrate. Figure 2(a) is representative of the GHRP-6 effect on the inflammatory response, illustrating the reduction of infiltrated cells as compared to placebo-treated wounds (Figure 2(b)).
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.

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.

Our peptide therapies are also known as secretagogues – a substance that promotes secretion.  These amino acid chains communicate with the body to produce or release growth hormone.  The increased volume of human growth hormone produced by the pituitary gland causes an increase in the production of Insulin-Like Grow Factor-1 (IGF-1) by the liver and results in several health benefits such as:
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.
The other submission commented on the consideration to place AOD-9604 in Appendix D. The submission supported listing in Schedule 4, but raised concerns that listing the substance in Appendix D would limit any future development work, including clinical trials that are currently being conducted on the substance. The submitter notes that there are currently 5 clinical trials notified to the TGA using this substance , with these approved clinical trials going ahead on the basis that the substance is safe for human use. Inclusion in Appendix D may place unnecessary burden on those conducting these clinical trials.

MGF stands for mechano growth factor—a peptide derived from insulin-like growth factor-1 (IGF-1), which plays a large role in childhood development and continues to have anabolic effects throughout adulthood. MGF has the ability to encourage repair and growth of wasted tissue through the activation of muscle stem cells, thereby increasing the synthesis of proteins necessary for tissue growth. This peptide is ideal of anyone suffering from muscle loss, either due to old age or a particular condition (i.e., HIV, cancer, etc.)
Additionally and not less relevant, GHRP-6 appears as an excellent partner to combine with other molecules (ie, epidermal growth factor [EGF]) because their exclusive actions seem to achieve a kind of synergism, useful to target the multiples nodes of complex pathophysiological processes, and thus to enhance tissue repair processes.56 Garcia del Barco and coworkers in our group have opened unprecedented avenues, by combining GHRP-6 and EGF as a therapeutic approach to ameliorate the damages of multiple sclerosis,57 peripheral axonal pathology,58 and brain ischemia in animal models.59,60 They have demonstrated that in all these experimental substrates the combined action of GHRP-6 and EGF is associated with a better outcome in both clinical and pathological fields.
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.
