So supplements are regulated by the fda by complaint. So if I release a supliment containing live rattlesnakes that's fine. They will look into it when they get a complaint and not before. Supliments are presumed safe and innefective. They are usually innefective so that is okay. What happens with gas station boner pills is that they buy vigra byproducts and sell them in the pill. Some times they work, sometimes they have too much, sometimes they have too little. The quality controll is poor because they intented to sell them for a few months untill they get shut down and then reopen under a new lisence to avoid fines. I once saw a man have a small heart attack because they were to strong. His wife was with him in the hospital just smirking quietly right behind him.
