I have a buddy who is a track athlete and is looking for something to give him a little more explosion of power when he runs... anything good out there to gain speed?
If he's a competitor I would just steer him to a running type of forum instead of supps that may get him into trouble
Sort of a broad question with nothing on his level of training, age, diet, exercise etc. Can't offer anything legal without knowing some basics.
Age is a huge consideration but i'll assume he's 22 since you are posting in the ANABOLICS section.
If he is old enough, Prostanozol (Mega-ZOL) may be something to look into. It is pretty much unmethylated winstrol. It doesn't give huge lean body mass gains but it helps lose fat and increase endurance/strength
