I have a friend who is only 21 years old. He has done a testosterone+dbol cycle already and now wants to try HGH. His plan is to use 5iu's per day for 5 months. I told him that he won't gain a lot from the cycle like that because his natural growth hormone output is still pretty huge and he would need a much bigger dose to get any effects. Is it true or is 5iu's/day enough for a 21-year-old guy?
The best would be to not use at all until at least 30 years old, but if he is going to use it anyway then he could do it correctly as well right?
