You could be looking at a lot of trouble if you don't do it right. Just do what Rick said or buy some test in Mexico and leave what you don't use there.
Yes you need it while running Tren also. It depends on the dosage and the individual. 800 mg is a shit ton of deca, especially if its the first time running it. Way too much
Good hell, this is reckless. That coach is going to get you in trouble. Why are you still running the test? I would shut this down and pct. Did you do any bloodwork? You ran 800 mg deca without caber?
