For your cycle, if you are using 400 tren e, I would increase the test to at least 400, if not 500mg EW. For your proviron, I would add it in for the last 30 days of the cycle at 50mg ED
And use your HCG in an insulin syringe. I would take 250iu every 3 days, taken IM with an insulin dart, into a muscle that has little fat, like a delt or tricep.
