Im just after some information about hgh this is the first time I've really looked into it and was wondering

How long a usual course goes for?

How much is taken per day for what result?

I've seen on other threads that hgh lowers body fat and increases lean muscle (after approx 6 months) but exactly how long until it starts to increase your actual body hieght/dimensions and at what iu?

Im 23 and 90kg, 6ft tall and have been training solid for several years now (i was a scrawny kid no more than 55kg at 17.... (sorry don't know a kg to pound conversion lol)
I've cycled on and off various times with several substances but I've always had that "i wonder what hgh would be like?" thought in my mind lol.

Am i too young for hgh?

Any advice is helpful.

Cheers!
