I am 23 5'11 140lbs -145lbs I run a lot that my 5k time is 19:35 and my mile time is 5:45. I have been reading up on some of the steroids a lot lately and saw that winn50 looked like it would be best for some one who is my ideal body-style and life style it is used among sprinters sometimes as well. I have used regular pharmaceutical stuff like every young person has in the past that you would find just about everywhere like GNC and not really gotten anything out of it.
I am looking for advise, tips for me to use in my choice between so many products that are out there thank you - Newb
