never used hgh. I’m 50 years old. A buddy of mine uses it and he swears that it completely changed his life. He says that he sleeps really good on it and he’s noticed a lot of anti-aging benefits. I’m looking to go 6 months with it. I just need some advice on the best dosing for what I’m looking for, in my age. Should I go 2iu’s per day? Or should I push it to 5iu’s?
