In my experience tren a is more effective. I got back on about 2 or 3 weeks ago (?) and could manage 2-3 (?) doses on time and went from avg weightlifter to bodybuilder after the 2nd dose with only an increase in bodyweight of about 7lbs. (Put on muscle and dropped bf)
*granted my "doses" were 100mg in each shoulder about 3-4days apart.
Got tren cough a lil bad on the last shot I did so I havnt done one since. Lol. Also, no test... Was waiting FOR FUCKING EVER for my reup to come in. Lol... Finally came and I've been too lazy to cook up my test's, eq, deca,npp, mast,drol,dbol,mtb(still gotta bunch though), etc... Haha. Been sittin on like 3000gs of rates for the past few days.
