2IU/day is the minimum. I am currently taking HGH at this amount. I am on week 5. So far the only thing I have noticed is a tad bit in fatloss, but this can also be from my diet, which is doing fairly well right now. But I have noticed my skin is looking nice, full, and healthy.
All in all, if you're looking to loose weight . .find something else. The price is just too much for this. Do a T3/Clen cycle, and do your best to keep focused on diet from then on. As for anti-aging . .yes, take 2IU/day and no less. Split the dose in 2. Also research more on this such as food intake and timing.
From what I see . . . HGH is only good for 2 reasons:
1) Mix with anabolics to get BIG faster
2) Anti-aging
Again . .expensive.
