A buddy and myself both did cycles, i did sustanon and primo, he is on test e and deca. The problem is he keeps injecting the test e in his delts, infact he injects it all in his delts where as i prefer glute injections. On his injection a few days ago the site on his delt has become swollen, red, warm to the touch and hurts to the touch. i didnt stick him like normal and i think he used a 18 gauge needle, i normally use 23. Anyone have any insight so i can help my retard buddy out before he has to get medivac'd for this shit.
