I think HGH stands a better chance of being taken advantage of when it is used to retain gains kept wihile on a cycle. In other words, smaller dosages, over the entire cycle would yeild better results than mega doses in 6 weeks - 12 weeks. I have never heard of anyone putting on 10-20-30 lbs from an HGH cycle, but I have heard of people putting on 20+lbs while on an anabolic cycle, and keeping all LBM gained post cycle using HGH.
If I were using it to help keep gains, 2 iu in the morning would probably be the way I would use it.
If I were using it to gain LBM, 6-8iu a day.
With the drugs price however, I think 2 iu is the better idea. I just wish I could find it for under some $700 for a 126iu kit! IP's stuff is questionable from what I hear, but if I were to use it, I would use at least 4iu a day.
