Do a search & you'll find more than enough info about ara test.
Ara test is no longer manufactured, & apparently the older stuff was great, but the newer lots are way underdosed. Check the older threads for the shitty lot #'s.
But I will say i've got a friend running 500 ml. of ara test 2500 weekly, along w/ some dbol, Eq, & fina. He is in week 4 & up 21 lbs. and he said his sex drive is still good.
