no delt shots. You'll want to keep all shots of sust in the ass and in the quads. Never heard of 350mg/cc (probably a typo). Here are some tips to a less painful injection...
1) fill a cup w/ warm water.
2) Drop the sust amp in the cup and let it sit for a minute.
3) When injecting, push the plunger slowly and steadily. (using a smaller needle -25g- forces you to inject slowly)
4) massage the injection spot after the injection.
5) use heating pad after injection
6) DON'T BE A PUSSY...NO PAIN, NO GAIN!!! (j/k -- you'll know if its infected, it will swell up and become red and you will start feeling real bad.)
