I have been doing cyp and deca combined since 3-10 and have not had an issue with pain for the most part when it comes to injections. The results I am getting are finominal. Only until just recently have I styarted to experience pain after injections from 3-5 days. My buddy is doing the same amount and injections per week and is getting same pain. Never did it become uncomfortable until the 2nd to last injection. It is a home brew and are in 30cc bottles. I was told that do to the bottle size there is more alcohol in the solution and that might have something to do with it. I started alternating from quads to traps to glutes and everytime it is uncomfortable for 3-5 days. Any ideas.
