My personal experience with it is that it is truly an anti-aging compound. I did an 8 mo cycle, various dosages, timing schemes, etc. The most phenomenal aspect was its ability to burn/melt away bodyfat especially from personal trouble areas that ALWAYS remained despite the best of diets and other compounds. A clean diet enhanced this effect, but this ability was also there while engaging in a poor diet. The majority of positive benefits didnt start exhibiting themselves until about 3-4 weeks into the cycle, but after that is was almost literally, daily changes observed in the mirror. I didnt pay too much attention to the, for me, secondary effects of skin and hair improvements, but they were noticed by others which made me look and take note. Skin just becomes much more resilient, younger looking and yes, wrinkles become less noticeable...making them dissappear...well, definitely less noticeable. It absolutely takes years off your face. I was 41-42 when I ran this and the changes were significant and noticeable by everyone that knew me. Never revealed my secret except my wife knew, but the youth enhancing external appearance is definitely a reality of HGH. Other than "feeling" better, I cant really comment on the benefit internally, but what I can say as with most other things, if the inside is not up to par, it will show on the external features, i.e., skin tone, hair loss, etc.
My #1 priority when I finally return from Afghanistan permanently in a couple years, will be to go on a more or less permanent cycle of HGH at 1-2iu's daily after a year of higher theraputic dosages and getting the ol' body back in shape. A truly amazing substance.
