im in my 13th week of a 500mg a week test cyp only cycle and its only the last month ive started to make noticeable gains. from everything ive learned i was under the assumption that it was 4-6 weeks to kick in fully. i will say that my nuts were shrunk in that time but my size and strength have taken off the last month. right after i started my cycle i caught that f*cking flu that was going around, TWICE, so my immune system was pretty suppressed, could that have anything to do with it? i was going to do 15 weeks but im thinking of going 20 since im so happy with my recent gains. ive been reading about low dose longer cycles being better lately so maybe ill guinea pig itthanks for any input.
