Male pattern baldness is genetically switched on at an age that varies very widely (some men in their twenties, some men never – look at the onset in males in your family). When the genetically inherited tendency turns on, then testosterone and it’s stronger (but less concentrated) metabolite, dihydrotestosterone, trigger the slow death of the hair follicles on the scalp in a male baldness pattern.
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.

Specifically, T α 1 has been shown to enhance the function of certain immune cells called T and dendritic cells. This is very important to anyone with a depressed immune system or suffering from an infection, as these white blood cells play pivotal roles in the body’s defense process. T cells, for example, come in two forms: killer and helper T cells. Killer T cells are responsible for hunting down and destroying our body’s own cells that are cancerous or infected with bacteria or viruses. Helper cells work with the other cells of the immune system to orchestrate and carry out appropriate immune responses.
Obviously, Increasing GH (and therefore IGF-1) levels are desirable for those looking to improve their physique in terms of increased muscle mass and loss of body fat, rejuvenation and strengthening of joints through connective tissue synthesis and bone mass density increases, as well as enhancing immune response and stimulating the immune system, particularly in those of us getting on in years (ahem). For anti-ageing purposes, GHRP-6 is normally singly dosed just before bed at night with users reporting the best night’s sleep they have ever had plus some funky dreams to match (since GH is released during REM or ‘dream sleep’ so the GHRP-6 sort of ‘forces’ us to dream). For bodybuilding purposes, users attempt to mimic pulsatile GH release for best results by administering multiple times throughout the day.
Hexarelin via CD36 occupation increases the expression of multiple genes involved in fatty acid mobilization in adipocytes toward the mitochondrial oxidative phosphorylation, and many of these upregulated genes are known targets of PPARγ. Consistent with this, electron microscopy of hexarelin-treated adipocytes reflects highly organized cristae formation that spans the entire width of mitochondria, with a concomitant cytochrome c oxidase activity enhancement. Although this signaling and activation cascade has not been described for myocardial cells so far, the potential existence of these phosphorylative and mitochondriogenic mechanisms in the heart, and its potential amplification by GHRP ligands, may eventually contribute to myocardial salvage during critical ischemia periods.47 In a more recent study based on a myocardial infarction model, and addressed to examine whether hexarelin treatment can compensate for ghrelin deficiency in ghrelin-knockout mice, the mortality within two weeks was significantly lower in the hexarelin (6.7%) and ghrelin groups (14.3%) than in the vehicle group (50%). Furthermore, hexarelin was more effective than ghrelin as judged by the ejection fraction and other LV-dependent physiological constants as dP/dt max and dP/dt min, which is a measure of LV global contractility.48
GH secretagogues differ from exogenous rHGH in their effects primarily because endogenous GH contains all five isoforms of growth hormone, whereas exogenous GH contains only the 20 kilodalton isoform. Different isoforms affect tissues in discreet ways that the 20 kDa isoform cannot. Administration of GH secretagogues causes a pulse-release of GH from the pituitary which is cleared from the body within a few hours. This does not significantly raise plasma insulin-like growth factor 1 (IGF-1) levels.[citation needed]
