Your body stops naturally producing gh generally around the age of 25. This why bodybuilders in Arnolds generation were winning Mr. O's in their 20's and retiring around 30, but Dexter Jackson can still place top 5 at the Arnold Classic in his 40's.
My point being, there is no reason to kick start its production because there will not be any production to kick start. HGH is a miracle drug though IMO and like Whitewidow said, why stop using it?
umm not sure bro, like i said i never read much into it.. but it makes sense, now i would use logic and say that your body doesnt COMPLETELY stop producing it but it does make less, would i be right ? so basically im 18 atm and don't even need to think about hgh ? plus its expensive as fuk bro( wouldnt be when i finish uni) so thats why you stop taking it lol, anyway would you say that when you're about 25-28 you should supplement it anyway ? like 2 iu a day ?
