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.


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.
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.
A multicenter study comparing the oral GH secretagogue macimorelin with arginine/GHRH found it to be safe, convenient, and of comparable efficacy (82% sensitivity, 92% specificity, and 87% accuracy in diagnosing adult GHD), with a GH cut-off point of 6.8 μg/L for patients with a body mass index (BMI) <30 kg/m2 and 2.7 µg/L for patients with a BMI >30 kg/m2 [268].
As a result, a general guideline for the purpose of achieving performance and physique enhancement is that of 100mcg administered three times per day. Each injection should be spaced evenly apart in order to achieve substantial HGH levels throughout the day due to the short half-life of GHRP-6 as well as the pulsatile manner of the HGH release that it causes. For greater results that would include more pronounced muscle gain and fat loss, more frequent injections would be required above the three times per day protocol. More details concerning the specific administration timing will be described shortly.
GHRH (1 μg/kg) plus GHRP-6 (1 μg/kg) is given intravenously at 0 minutes and blood drawn for GH sampling at 0 and 120 minutes [200]. GH releasing peptide-6 (GHRP-6) is an artificial hexapeptide [96] that activates the ghrelin receptor [98]. Combined administration of GHRP-6 and GHRH is the most potent stimulus to GH release, with excellent reproducibility and no serious side effects [96]. GHRH/GHRP-6 is a viable alternative to the ITT in patients with organic pituitary disease, however there is overlap between GH levels attained in the control group and severely GH-deficient patients. Since GHRH and GHRP act directly on the pituitary, it is possible that their administration restores GH secretion in patients with a deficiency of these secretagogues because of hypothalamic disease [201].

GHRP-6 and all GHRP’s are mimetics of ghrelin, a hormone produced by cells of the stomach in response to a fasted condition, including brief fasts. Ghrelin and ghrelin mimetics work by activating the ghrelin receptor, also called the growth hormone secretagogue receptor (GHS-R1a). Elevated ghrelin levels act towards increasing GH levels by stimulation of ghrelin receptors in the pituitary.


GHRH/GHRP-6 was the first of a family of synthetic peptides that enhance the release of the GH by the pituitary gland in a dose-dependent manner. Since its discovery, it has been used as a benchmark and starting point for many of the research aims to obtain new drugs, but none of its implications are more engaging than the treating of the obesity epidemic.


The delegates have decided that the relevant matters under subsection 52E(1) of the Therapeutic Goods Act 1989 are (a) the risks and benefits (b) the purpose for and the extent of use (c) the toxicity (d) the dosage, formulation, labelling, packaging and presentation (e) the potential for abuse and (f) any other matters considers necessary to protect public health.
It does not matter what your intended use it; whether it is for weight loss, muscle mass development, lean muscle mass, or simply to increase HGH to their natural levels, you should always maintain the same dosage levels throughout the entire cycle. Do not increase use if you believe you aren’t achieving the results you are hoping for, as this can result in negative side effects or lacklustre results.

Serum ghrelin levels vary as a function of energy balance. Ghrelin levels are increased in anorexia and decreased in obesity.78 Thus, it is possible that ghrelin may be an important player in food intake behavior and perhaps in chronic over- and under-nutrition as well.9 Because of its dual effects, ghrelin may be a critical hormonal signal of nutritional status to the somatotropic axis, playing a role in integrating energy balance with the growth process.10
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.
Ghrelin has been linked to inducing appetite and feeding behaviors. Circulating ghrelin levels are the highest right before a meal and the lowest right after. Injections of ghrelin in both humans and rats have been shown to increase food intake in a dose dependent manner. So the more ghrelin that is injected the more food that is consumed. However, ghrelin does not increase meal size, only meal number. Ghrelin injections also increase an animals’ motivation to seek out food, behaviors including increased sniffing, foraging for food, and hoarding food. Ghrelin also readies the body for the incoming nutrients by stimulating gastrointestinal motility and gastric acid secretions.
The topic of Growth hormone (GH) can leave you wondering: is it a good, or a really bad thing? Look into the cold science of it and you’re left with a sweet and sour aftertaste of indecision from weighing up the risk-reward ratios with each cyberspace headline swaying the balance of power like a tabloid romance. Why the fascination? Well, over the years growth hormone (GH) has garnered celebrity status, not just in the world of exercise, but on the crimson rug too, since becoming a must-have for Hollywood A-listers who need to look their best. Taking it regularly gives you a more youthful appearance, serves up more energy, burns fat and improves muscle tone. The $10,000+ per year price tag does nothing to harm its appeal with the elite either. However, a more affordable and potentially no-less effective substitute, in the form of growth hormone releasing peptide-6 (GHRP6), is offering the injectable fountain of youth option to the man on the street. Seeing the word peptide in its name, means its made up of 28 tiny amino acids – the building blocks of a complete protein – that acts like a self-inflicted punch to the kidneys to your natural supplies of this powerful health elixir. Yes, it does reside in a legal grey area, and we certainly don’t condone its use or suggest you use it. Instead, this article is about giving you scientifically sound information on the latest developments in supplements. So, caveats aside, keep reading to learn about this provocative supplement.
