Well I have experience with hgh for several reasons. I've been on it for few years before and currently.
First it was for recovery from injuries which I can tell you it worked like magic.
Second, the last few years I've been on it for overall well being, youthfulness and fat burning capabilities as well as recovery.
I've been taking 1iu a day and I know it works well... my own hairdresser and nail girl noticed changes in my skin, nails and hair... her exact words were that they grow healthier, my skin tone even and glowing (I barely ever wear any make up and people ask me if I do or what I do to get such good skin) plus I look way younger than I am. I'm in my late 30's and look like early 20's in person.
Plus I had surgery recently which I recovered pretty fast. It took me out of the gym for few months but I haven't set myself back at all.
So yes I highly recommend it!
