I am currently doing a cycle of sus 250 2x week and my first 2 shots went in each deltoid. My 3rd shot went in my right thigh and it was a bit more painful but tollerable. Now its 3 days later and its still painful. Not excruciating or anything but just enough to know its there. After my delt shots it only hurt for a couple hours. Whats going on? Are the thighs more sensitive or something?
