Ive only done 2 previous cycles,both with test cyp,the 1st one was 500mg/week and the 2nd was 600mg/week both times no sides at all,except some acne was all,my upcoming cycle im going to do is test cyp and deca....thats one reason for the thread,ive never used deca before,and was just curious about when to start taking it, with my 2 previous cycles i wasnt prone to estro or water retention............thanks for the help guys
