i do prop/tren ED pins, alternating front delts, medial delts, glutes, and quads. i agree quads are the most problematic of the places i have shot, nothing but a maze of veins....so far no violent blood spurts and no abcesses, i aspirate and sanitize EVERY SINGLE TIME.
8 sites in rotation for 6 weeks + 1 day, so 43 hits so far on my first cycle with 25g
havent gotten any shrinkwrap sounding weird effects yet..
delts are the most painless site thus far, only prob is shooting 2 cc each time sometimes a couple drops leak out
