I think they are worthless, youd get more out of eating slightly better or taking an extra protein shake a day then with that crap, a few people I know got gyno from that shit and it never seems to help gain any muscle. my .02
Prohormones will fuck you up. I believe there more dangerious then AS use. I took prohormones about 2 years ago and that shit gave me the same thing deca will give you which is deca dick. I had to go to the doc and get a shot to regulate my hormones. Prohormones are worthless just wait untill you can get the real thing,
