Supplement Watch I just used this to check up on Synephrine HCl (which is offered in a discounted stack with Biotek ephedrine and caffeine at 1Fast400), and I was pleased to learn it's an excellent aid in losing weight. So I bought the stack, instead of ephedrine and caffeine separately, and saved myself some money, as well as increasing the potency of my stack. In case you're shrewdly wondering if this website is just a front for the supplement industry, as I always do, they highlight this in red on their "About Us" page: In addition, we rely only on our membership fees for our operations, and do not accept advertising or funding from supplement manufacturers. Now, this doesn't mean I'm sold. After all, they only say "supplement manufacturers," but the majority of supplements sold are distributed by those who don't actually manufacture supplements themselves...but I thought I'd put this up and see if anybody knew more about this website.
