Shelton and Rajfer (2012) noted that androgen deficiency in aging men is common, and the potential sequelae are numerous. In addition to low libido, erectile dysfunction, decreased bone density, depressed mood, and decline in cognition, studies suggest strong correlations between low testosterone, obesity, and the metabolic syndrome. Because causation and its directionality remain uncertain, the functional and cardiovascular risks associated with androgen deficiency have led to intense investigation of testosterone replacement therapy in older men. Although promising, evidence for definitive benefit or detriment is not conclusive, and treatment of LOH is complicated.
You will have to use HGH in a pulsate manner, meaning injections taken every second day gives better results than daily injections. Rather use the higher end of the dosage range on these days. For instance, instead of using 3IU's daily, rather opt for 6IU's every second day. Dosing should be at periods not close to sleep or training sessions, or close to supplement ingestion containing Arginine, OKG or GABA. It’s more effective to use it early morning and later again before lunch. Follow each dosage by ingestion of at least 50-60gr high quality hydrolyzed whey protein, taken in at temperature of about 4C this will improve gut emptying and by the time the IGF-1 is released to the gut, your whey is available for absorption. Do not use Insulin around the same time as your HGH, neither use IGF-LR3 or MGF close to HGH dosing.
Lactones contribute significantly to the flavor of fruit, and of unfermented and fermented dairy products,  and are therefore used as flavors and fragrances.  Some examples are γ-decalactone (4-decanolide), which has a characteristic peach flavor;  δ-decalactone (5-decanolide), which has a creamy coconut/peach flavour; γ-dodecalactone (4-dodecanolide), which also has a coconut/fruity flavor,  a description which also fits γ-octalactone (4-octanolide),  although it also has a herbaceous character;  γ-nonalactone , which has an intense coconut flavor of this series, despite not occurring in coconut,  and γ-undecalactone .
