You absolutely can mix your compounds, id rather do one injection into one site and mix the oils, I just did a shot of test and primo today zero pip, primo has come a long way and labs have figured out how to minimize pip if you get quality primo.Ive never pinned anything other than my trt. Do yall pin primo and test together? I've been reading mixed answers about it causing pip especially if you use the 200mg/ml primo
I've run primo and test for 2 cycle straight, if u have issues you can run the barrel under hot water for a few minutes and shake it to mix the oils together, it will cujt down on pip, just make sure the syringe part has the plastic cap on it while u do it.
