bro...that is an excellent idea...i was inj'ing 1.5cc in each bi and another 1.5cc in each tri.the pumps you will experience will be out of this world.strength gains come quite rapidly while on fina,so make sure you take advantage of that and force those arms to GROW.they will swell while you're on,but once the inj's stop,you WILL notice a difference...neverthless,i gained a full inch after my tren use...by i beleive that this was achieved by using heavy weight...take advantage of the strength...---fyi---GOOD LUCK w/ your cycle.
PS:i used a 23g 1" to draw and 25g 5/8" to inject...smooth like butter...
