this question isn't as simple as it sounds, im not a newbie so dont flame...i am an NCAA athlete...i am not thinking of juicing right now because it is during my season and might get tested, but what i was wondering is the real difference in the test esters....i know that it is release time, but is there a particular chemical in the test that causes that....ex. i know that cyp has the longest release time, and prop or suspension has the shortest(im not sure which of the two)...the NCAA test for a 6:1 ratio as most of you probablly know...so, finally, here is the real question....if i were to do test and get tested, would they know which test i was doing...could they tell if i was on prop or ent...or would they just know that i have elevated test levels......hope all of that makes sense
