It's an MLM, meaning multi-level-marketing thing. I have 2 friends that do it, one of them makes a good bit of cash on the side with it. Check with your doctor to make sure it is safe.
Stay away from it bro......unless its to make money. Its waaaay over priced and not worth it. My buddy got talked into it from his mom when we were in bagram. He was on it for months with zero effect. You can make some money if u have a target market but there are far better suplements for a fraction of the cost
