Whats the smallest gauge needle you guys would use for a tren/prop mix, that depending on the muscle being injected ? Im going to be doing a tren/prop cycle here soon and was wondering what the smallest gauge needle i could get away with for the follow injection sites - delts, thighs, tris, bi's. Could a slin needle work of 27g or 29g for these sites. I'll also be doing glute injections but ill just go with a 1 1/2" 23 gauge there.
