it seems to be the concensus the 2iu for basic maintenance and well being, i got this right from the gen-sci website:
Result of well being, some lipolysis,improved skin appearance: 2iu daily
Moderate lipolysis, better sleep, more energy: 3iu daily
Begin to see fullness in the muscle,advanced lipolysis: 4iu daily
Muscular hypertrophy, feeling like a king, full as hell: 5iu daily
i know it will vary from person to person, as weight and fitness will play a role. would it be better to work up to a high amount, say 4 or 5 iu then when you get to where you want back down? what does anyone that has experience with hgh think?
