Supervised Anti aging dosages of 1-2iu per day are pretty harmless and there's no sides with Pharma grade, Chinese yes at times mainly from the product additives to assist with shipping or they are overdosed as they know shipping will effect potency. Its more of just a metabolism booster at that low dose than anything substantial, works well alongside genuine TRT dosages, will help you move that stubborn brown fat. At higher dosages I agree with others it will grow all cells. You're mad to take high dose HGH if your not competing seriously especially if your over 40. Just an opinion I share with my genuine AA doctor. But it can be beneficial.
