I'm running test prop and primo together for 12 weeks. I thought 10 would be enough but most on this forum think 12 is the way to go. I'll be injecting test prop EOD and primo twice a week. I will also mix the primo w/test in the same dart to minimize injects. 12 weeks of EOD is a lot of shots. How often am I going to need to rotate sites? I prefer the glutes and delt. If I'm shooting a total of 4x a week, can I hit glutes twice and delts twice each week or will I have to start looking for new spots? Thanks
