Hi, im 21, i have been lifting for about 3 years, and I think I might have low natural test levels, because I havn't really made any progress in my lifting in awhile, and my libido has been really low like the last 6 months or so, its been hard to get erections, and when i do, they dont last very long at all unless i am getting head or something. its really frustrating when im with a girl and were doing things, and the **** won't work right. but im only 21, why in the hell would i have low test already? i have never used steroids or pro hormones or anything of that nature. is there any way to tell if u have low test? but neways guys, let me kno what u think, all advice is welcome. love the site btw, and if this thread is in the wrong place, im sorry. thanx guys. peace.
