My friend is all natural,and he wants a good suppliment.He doesn't want a Prohormon,because last time he used one he lost his sex drive,and his nut hurt.I was thinking of telling him to get some Syntheteks B-12.I told him that it will give him energy,and will speed his metabolism.He is looking for energy,keeping strength(possibly gaining more),and some fat lose.What does everyone think?He doesn't like pins,but i can get him to pop a few sub-q.I told him,it's very easy and no pain.
