Bro, I have tried Biotest Androsol and Tribex500. I can tell you I liked the Tribex500. I used it when I needed to and it worked. it also stimulated my appetite. As far as the Androsol. I was not to fund of it however prohormones have really never worked for me however they do work for some people so I am not bashing it just giving you my experiences. If I was going to recommened A prohormon eit would be the topicals by Biotest because of the feedback I have heard on this board. By the way, the Tribex500 was good.
