I don't want to say steroids.... but...
That would make a ton of sense in this situation. Most of the time though, steroids are used to relieve cramping/soreness of an area of fatigue when injected, not the other way around
This is why you have to drink lots of fluids when you take those PED's. i have used creatine monohydrate foru work outs and the moment i dont take any fluids? Boom... It hits me! Remember those incident in florida where they said le bron's agent/manager/friend picked up some pills and signed out with the LJ innitial?
Creatine monohydrate is not anything like steroids
