Any time you introduce test prop, the chance of pain goes up. It is all individual. I used to get pain from prop, but not at all anymore. A lot of it has to do with how much your muscles are used to oil/hormone injections. This all being said, Adding in andromix to the end of your deca cycle is not going to be a good move. First off, it'll take a couple wks to really kick in and second, its not a great idea to mix tren and deca. Progesterone can spike up through the roof, which isnt ideal, expecially right before you start PCT. If you want to find something to run while you wait for the 3 wks of clearance, maybe consider an oral, as they act very quick and clear quickly as well. Honestly though, you wont need it. You'll still be feeling good pumps and strength from the deca, well into the start of PCT
