Apparently this moron Marcus Llewelyn is an MD. I don't know where he (allegedly) went to med school, but if seemingly lacks a basic understanding of how the liver works. Drugs are still filtered by the liver once in systemic circulation, not just when they enter circulation through the hepatic portal vein.
I also call bullshit on his firm being FDA licensed. Note that his brand is 'Enhanced Arsenal', not 'Enhanced Athlete'
