There are 3 products I've seen that I've always been curious about and wanted to see if any of u guys have tried and had good effects from.I know its for the reduction of body fat and helps maintain muscle but how good is it and do u really not lose muscle? I've heard its an alternative to creatine for those who don't want water retention. What is it really and how good would it work for an 18 year old. I've been told it helps u naturally produce test and get better deeper sleep thus promoting growth and hgh. How good is it again on an 18 year old.
