I think pre determining doses is a little foolish. Or unnecessary. Say you went with option number 1 and on week 8 everything was working perfectly, why would you change it? Also you been on 250mg of total gear, why are you going straight to 1000 with 500test and 500 something else?
Pick the compound that works better for you, in my case it would be test/eq. 250 each for a couple weeks while you increase your calories. When the scale stops moving go to 500/500, when the scale stops moving it's time to increase your calories again, then maybe twords the end bump it again.
But trust me 16 weeks on 500 test/ 500eq
Or 16 weeks on 500 test/500deca
Or 750 test 500 whatever,
There's all gonna produce similar results. Doesn't matter what you pick it all, what matters is what you do with your food
