quite honestly, 1AD was the first cycle i ever did. i gained about 12 lbs and loved it. i have now experimented with different compounds and still like what the 1ad did for me. probably because it was my 1st cycle, but it has remained in my top 3 cycles i ever tried. but to answer your question, 1ad and m1t are completely different compounds. i tried 2 cycles of M1T and will never touch it again. it made me feel like trash (mood swings, no libido), and i couldn't seem to get off my lazy ass. that was even when stacked with legal gear 4ad+ (still not sure if i wasn't ripped off on that garbage). anyways, for best results go with the tried and true. 1-test/4AD transdermal.
