I would not run deca and tren together. The progesterone build up will be much higher. Instead, I would opt for EQ and tren. EQ is test based instead of 19-Nor so the only thing that will directly raise proges is the tren. So your chance of side effects related to this is going to be much less and your cycle will probably be easier to recover from. If you have run a 750 test/500 deca cycle last, dosing on the EQ might work well around 500-600mg. If you want to help your recovery, you could always run some HCG through the cycle, starting at any point, taking 250-500iu 2x wk and ending it a few days before PCT
