ED shots with Tren/Test/Mast is a bitch if you dont have several sites to rotate. I rotate between glutes, delts, chest, quads, bi, ventro glutes. I have 3 sites in my delts, rear, middle and front. I have not tried pinning tris, traps or lats, but will definitely consider it in the future.
My left quad swelled up really bad and gave absolutely excruciating pain from a mix of test and eq. Now I don't do quads at all. Side delt, front delt, pec, pec, front delt, side delt repeat.......All those spots give minimal pip and never to point of affecting my training unlike quadd. I won't touch quads again.
I was very close to going to clinic for my quad but finally after about 8 days swelling went down....can relate to milking being nervous as a hooked in church lol didn't wanna go to clinic and explain that
