You're probably better off spending your $$$ on AS. However GH when combined w/ the proper use of insulin and an assload of AS the results can be pretty amazing-if you don't mind the risk of death if you fuck up. If trivial things like that don't matter to you, you can find out how to do it responsibly from someone here somewhere. Even then, there's risks involved where the end result could mean death.
At 2 iu's/day, you're looking at 6 months minimum to make it worth your while. Even then results won't be that dramatic. 4 iu's/day for 6 months might do you better??? But as I stated earlier you're probably better off spending your $$$ on human grade AS.
I've probably taken 600 iu's of GH in my life.
300 iu's were with insulin and approx. 2000+ mgs of AS/wk and I made incredible gains-of course the fat gains that accompanied the insulin/carbing up process required T3 and Clen to offset them. I felt like an Rx garbage can-but I grew like a weed.
With that being said, if someone offered me $4000 of HGH for free or $4000 worth of AS for free-I'd take the AS, hands down. However, I do think 2 iu's/day of GH alone for 6 months might really be great for guys 35+-but mostly for age reversal therapy, not major physique transformation.
