test is test, plain and simple. all that is different are the esters, which can be short or long acting esters. prop is a short ester which means the testosterone is in the body quicker but the half life is short, hence having to inject everyday. test e or c are longer acting ester, meaning they react with the body a litte later than prop would. the half life is long meaning its in reacts in the body for longer periods of time. hence, an injection e3d. with my prop i am currentyl going to run winny with it. i will run it for the last six weeks of my cycle. i am only doing this to cut up more so i can maintain a low bf% for spring break. you know how it is, gotta look good on spring break. first time to show the world how well you've worked out to get the body.
