My nephew hit me yesterday (I’ve become the fitness Oracle, lol) and asked me about Bull Shark Testoterone! From the name alone I told him do not mess with it! From my commom knowledge, Bull Sharks are pretty aggressive animals and I thought, this is the stuff that makes Rapist out of men! Anyway after trying to research it, I found NO CREDIBLE SOURCES OF NEWS about it. It was all forum talk.
Anyhow it seems to have come to life from a Grand Theft Auto IV video game and that alone is a red flag! Anyway the best info I can find is by a self proclaimed Nerd named Christie Wilcox which you can read here. I suggest you read this before juicing!
