Bitter Orange (Citrus Aurantium) contains synephrine and can give you a heart attack. It raise systolic blood pressure while not doing much else. You won’t find this in Biotest products, but this crap is in alot of “supplements” on the shelf. They take the good stuff off the shelf and make it illegal and leave the dangerous crap behind.
Good point! Throw in some creatine blockers that are so popular these days, and you’re all set!
