The Sust contains 30mg Acetate, 50mg Prop, 50mg Phenylprop, 90mg cypionate, and 105mg decanoate. I have another question though. Whenever I do cardio involving jogging or running, I think its called my Tibialis muscle really tightens on me to the point it is impossible to even walk on. Could this be from the Sust? I wouldnt think so, but it just started while I am on cylce so am curious. Thanks again!
