Normal GH secretion, whether spontaneous or evoked by provocative stimuli, is markedly blunted in obese patients who display, as compared to normal weight subjects a reduced: half-life; frequency of secretory episodes; and daily production rate of the hormone. Scacchi, et al found that the combined administration of GHRH and GHRP-6 represented the most powerful GH releasing stimulus among obese patients, which was still less effective than in lean body mass subjects.They concluded that treatment with biosynthetic GH has been shown to improve the body composition, and the metabolic efficacy of lean body mass in obese patients undergoing therapeutic severe caloric restriction. GH and conceivably GHRPs might therefore have a place in the therapy of obesity.11
The conclusion comes down to which peptides should you use. This is going to depend on personal use and experience. Whether you are into bodybuilding, gaining an edge in sports or just looking for health and wellness and anti aging properties, peptides offer a little something for everyone. There are many peptides that are not covered below, but as an introduction into the peptide world these are the most generic and widely used. As with any supplement or drug, please do your own research before diving into using peptides.
Of particular note is the variable chemistry of GHRPs, which consist of three major chemical classes including peptides, partial peptides, and nonpeptides, all of which appear to act via the same receptor and cellular mechanisms. Generally, most GHRPs are active by all routes of administration, specifically intravenously (IV), subcutaneously (SC), orally, intranasally, and intracerebroventricularly (IVC), which supports their possible broad future clinical utility. From evolutionary studies starting with the zebrafish, the natural receptor and hormone have been present for hundreds of years, underscoring the fundamental evolutionary and functional importance of the ghrelin system. GHRPs were well established to act directly on both the hypothalamus and pituitary several years before the GHS receptor assay.23

From the examination of many studies, the saturation GHRP-6 doses have been determined to be 1mcg per kg of body weight, and an average dose of approximately 100mcg without concern for bodyweight[1] [2] [3] [4]. That is to say that a 100mcg saturation dose of GHRP-6 will fully saturate receptors, and that 200mcg will only provide 50% additional effectiveness, and a 300mcg dose will provide only 25% additional effectiveness, and so on and so forth. This is very much the case with almost all GHRPs and GHRH analogues, as it seems to be the nature of these peptides.

The response of these wounds reminds us of the pattern of healing described for MG53 protein (a membrane repair machinery member), so that the treatment facilitated wound healing along with a reduced scarring in rodent models. This antiscar effect was explained by interfering with TGF-β-dependent activation of myofibroblasts differentiation and reduction of ECM proteins accumulation [22]. Similarly, antiscarring healing properties are described for plants’ principles that downregulate the expression of fibrogenic-related molecules such as TGF-β1 and the downstream events, leading to fibrosis and scar formation [23]. In addition to a direct action of GHRP-6 on TGFB1 gene expression, we deem that the reduction of inflammatory effectors could have also contributed to enhancing the healing process and to reducing fibrosis. In an animal model of liver ischemia/reperfusion, we previously demonstrated that GHRP-6 prevented internal organs parenchymal activation and the onset of a systemic inflammatory response syndrome by downregulating proinflammatory cytokines [24]. Subsequent studies have demonstrated the ability of different GHRPs to ameliorate local and systemic inflammatory processes in a variety of experimental scenarios by suppressing the activation of NF-κB, the consequent expression of proinflammatory cytokines, and acting as chemokine receptor antagonist [25–27]. Differentiation to myofibroblasts, collagen fibrillogenesis, and matrix accumulation are controlled by opposing forces: proinflammatory and profibrogenic, that require a fine tuning to ensure a proper esthetic healing and effective mechanical properties of the ECM [28, 29]. The overall interpretation of the data from (i) the rate of closure, (ii) microscopic appearance of the collagen fibrils alignment/organization, (iii) impact of the treatment on the transcriptional expression of cytoskeleton filamentous proteins (smooth muscle α-actin (α-SMA), desmin, and vimentin) supports the hypothesis that, in this context, GHRP-6 has shifted the balance toward “a more regenerative” rather than a reparative phenotype.
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?

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.

Another major difference between GHRP 2 and GHRP 6 is that the former is a bit stronger and releases a lot more Growth Hormone as compared to GHRP 6. Therefore, if increasing Growth Hormone in you is of prime importance then consider choosing GHRP 2 makes a lot of sense. But the importance of the latter in stimulating appetite cannot be ignored altogether. Though GHRP 2 can also be used for the same purpose, it is certainly not in the same level as that of GHRP 6.
Peptides are short chain amino acid monomers linked by a peptide bond. The body utilizes these short amino acids chains to secrete/pulse growth hormone (GH) that is already stored in your body. This is a very attractive option for those who are not able to utilize synthetic human growth hormone (HGH) naturally. In fact, this could even be a safer alternative for those seeking to use growth hormone for recovery, anti-aging and fat-loss. There are a multitude of peptides on the market and new ones being created almost monthly. Therefore, for the sake of an overview, let me just touch upon the ones that are most commonly used. To begin, let me start by first breaking down the two most important peptide groups for bodybuilding.
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.
Whether it is GHRP 2 or GHRP 6, it is better to get in touch with your physician before you get on with the consumptions of these peptides. In any case, when you are following an exercise regimen of extreme type coupled with special supplements and diets, a complete assessment done by a competent physician is highly recommended. Both the peptides – GHRP 2 and GHRP 6 have their own set of advantages and disadvantages, similarities and differences. It all boils down to individual choices and requirements when it comes to choosing between them.
In 1999, seven adult patients with GH deficiency and LV failure received hexarelin administrations. The GH response to hexarelin was negligible in these patients. Moreover, hexarelin administration increased their left ventricular ejection fraction (LVEF) without changing catecholamine levels, mean blood pressure (MBP), or cardiac output. For the first time, the acute administration of hexarelin proved to induce a positive inotropic effect in humans, which is GH independent and mediated by specific myocardial receptors for a GH secretagogue peptide.29 A subsequent study involving hexarelin administration to normal adults, severe GH-deficient patients (N = 7), and patients with severe ischemic DCM (N = 12) confirmed that the acute administration of hexarelin exerts a GH-independent positive inotropic effect likely mediated by specific GHRP myocardial receptors.30 This pioneering group subsequently evaluated the cardiac performances of the acute hexarelin administration (2.0 µg/kg, i.v.) in patients undergoing bypass surgery in comparison to patients given GH-releasing hormone, recombinant human GH, or placebo. The study concluded that the acute administration of hexarelin improved cardiac performance without any relevant variation in systemic vascular resistance and induced a reduction of wedge pressure and, significantly, that these cardiotropic effects were not shown by the other concurrent interventions.31
IGF-1 is the only natural hormone that can stimulate lean muscle mass gains and help the body choose to burn stored fat over simple glucose for fuel, meaning, you will burn off more fat. Studies demonstrate that only colostrum supplements containing lactoferrin can produce lean muscle gains that complement IGF-1 supplementation. That’s because it is actually the lactoferrin in some brands of colostrum that work to increase muscle mass and to burn adipose tissue. In fact, in a recent 2013 study, participants who supplemented with lactoferrin over a period of eight weeks experienced increased weight loss, reduced visceral and subcutaneous fat, reduced waist circumference, and reduced hip circumference.
When taking Ipamorelin, you want it to be pushed through your system naturally, and at the same levels. If you are constantly altering the times you take it, or increase/decrease dosages during your cycle, this is not going to be attainable. To maximize the benefits and gains you are going to experience, dosage levels should be consistent, as should the timing of the dosage you are taking each day.
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.
As both CJC1295 and Ipamorelin bind to the pituitary gland and prompt the release of GH, when used together, the production of growth hormone is over 10 times more than when used individually. As it stimulates the body’s natural growth hormone production it also causes the release of IGF-1. The advantages of the CJC peptide is that it helps increases bone density and collagen, as well as boosting the immune system. It will also produce new muscle cells which will be leaner and increases weight loss. The CJC 1295 results are part of years of scientific studies. It primarily increases the production of proteins, which leads to stable bodily functions related to the glands in the body or the endocrine system.
Taking into account the broad spectrum of TGF-β1 physiology in the fibroblasts/myofibroblasts differentiation events [33], we deem that the reduction of the local scar cellularity and perichondrial matrix accumulation in those animals receiving GHRP-6 could be attributable to TGFB1 transcriptional and functional switch-off. Since the predominant microscopic aspect of the GHRP-6-treated wounds was characterized by meagre cartilage scars, slimmer perichondrium membranes, and far less active cells, we hypothesize that the peptide somehow attenuates the perichondrial activation response to the trauma and/or a possible mesenchyme-to-mesenchyme redifferentiation process, thus lessening the surge of fibroblast and myofibroblasts. In line with this notion, we had documented that GHRP6 prevented hepatic stellate cells activation by reducing CD68, α-SMA, and vimentin local expressions. All these events could be primarily presided by the GHRP-6-related reduction of TGFB1 and CTGF expression in both parenchymal and nonparenchymal cells [7].

With a blend of peptide and GH supplements, Ipamorelin can greatly help you in your weight loss endeavours. Using it with IGF-1 which is a natural growth hormone, can help you achieve even greater results. With lower dosage, you won’t increase muscle mass, your body will naturally decrease body fat levels, and you will begin to metabolize food faster, meaning you burn more calories in less time, for greater weight loss results.
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.
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:
Light-headedness and dizziness: GHRP-6 might commonly cause what is commonly referred to as a “head rush” feeling accompanied by a tingling and “pins and needles” feeling in the extremities, as reported by many users. This can also present itself as a spell of dizziness and/or light-headedness. It is in fact a strong indication that the hormone is indeed stimulating the pituitary gland, and is a side effect indicative of almost all HGH secretagogues.
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.

This is a great option for those who are looking to promote a steady and improved release of GH to get the benefits of increases in growth hormone and subsequently Insulin Like Growth Factor -1 (IGF-1) with almost no side effects. This therapy is effectively used for anti-aging purposes as well as those with inflammatory conditions, disease or those who have low IGF-1 levels.
