I'm going e3d with 1.7ml into L or R quad. So the same quad doesnt get hit but once every 6 days. Is there a physical reason that it would be better for me to switch to more locations?...The gluts just arnt as convenient to hit and I feel better going into a large group like quads more than delts. I could easily switch though if it were something like receptor issues. Please lmk,
