heres a little info on me. im 18 years old, 160 lbs and im 6'0''. as you can tell by that, im not a huge bastard, nor am i aiming to be. i run track and what i have for times and stats arent that bad. 20'11'' in the long jump, 11.6 in the 100m dash, 4.78 in the 40. Im looking for something to give me a quicker jump from the start and to keep me going fast. i just got some 50 mg winstrol tablets. from what ive heard they will help me with the speed, but i also already have knee problems (ligament damage from football) and i dont want these problems to worsen. im wondering if anyone knows something i can take that will make me faster without much damage to the cartilage or joints. thanks
