This is my first time on primo, does primo leave the injection spot sore? So far it has been 400mg of Test E and 200mg of Primo in each glute and my glutes are sore and a little swollen. I know the Test E has little to no pain for me so it is either the Primo or a infection in each glute. I am going to go ahead and bake both bottles just incase, I dont want to walk into the ER with a abcess in both glutes, both quads, and both delts.
