Option C is favorable. Any specific reason you’d drop the NPP by 100mg in the 10wk.
I’ll be running very similar this winter 650 Test and 450 NPP for 10 weeks and might put 4 weeks of anadrol in at 100 mg/day at the end.
500 mg/week will be enough for your 2nd run with NPP. The least amount for effective dose. 500 mg of NPP is probably equivalent to 600 mg of Deca due to the lighter ester weight.
2nd reason is the broscience of deca dick, keeping the testosterone higher than nandrolone. I don’t know if that’s true or not but I never want to find out. Never had a problem so far.
