I used what is called Black Dragon Labs Testanate 50 and it seemed to work pretty well i went up like 12 lbs in weight and my strength gain went up really well. My max bench used to be 225 and now i rep that i know its not alot but i guess it is for me and being natural (with out aas). I just used two bottles and went by the dose that was suggested at 2 pills twice a day. But it come with a warning on the cap that says to only take on pill twice a day and do NOT exceed that but i didnt listen and got pretty good effects from it my pics are on the pics page labeled before and after. I have been off it for probably a month now and ive kept almost all of my weight gains and ive stayed as strong as when i was on. To me it was a pretty good product. I think i might stack that with the havoc next time around. Or just get the real thing i already know what everyone will say. Dont waist my money and get the real shit lol.
