i am brand new to the gym world as of maybey about 3-4 months now.... im loving and a enjoying it greatly when i started i was slow and wasnt really into it... so looking stuff up on the internet i found tribilus labled Testo-Rex i finished the bottle in that month (90 caps or 1 months worth) im not trying to sell it... ive been told it was crappy and not strong enought but it was like it gave me a kick in the nuts and got my shit jump started (pardon my language) now i run to the gym and i love it.... havent gotten more since that first bottle though..... debating wether or not i even need one??
