bro i am on 1000 mg of test enanthate per week ,along with 600 mg of eq per week, and i slpit them up half on tues, half on fri, and i have no pain at all. Suck it up bro, shooting in your legs is easy, and IMO it hurts less than the glute. Maybe its your technique do u shoot really fast? that can make it hurt alot, i dont knwo what kind of gear u use, but it shouldnt be that painful. Try warming the oils up before u shoot, then massage after the injection.
Only those who will risk going too far can possibly find out how far one can go.
