I haven't used it in many many years! I use to love it, I was in the best shape of my life back then, it helped me stay super lean, and it was amazing to have sex on! But i haven't seen nor heard of it in many years, nor would i go anywhere near it these days! That shit is bad news, I've seen bad things happen to people on it!
But back to your OP, its amazing to take in moderation before bed! AMAZING! Problem is you sleep so sound for a few hours that your up and ready to go for the day way to early! But its good when used properly , real good
