i would like to know if anybody can tell me what sort of test dose would not interfere with your nat test levels, im currently running a test and decca course, im six weeks in, got six to go, but being 39 i cant tell you how good i feel when on gear, before this course i felt crap, tired all the time, after my first week on sust i felt 15 years younger, what im looking at doing is take a low dose of test between cycles , can this be done without messing up my bodys own test production, cheers dan
