Dosing is kind of individual, within reason, based off of your previous experiences. I have helped guys that have done cycles of 1cc test every wk. I wouldn't tell them to take 750mg test for their next cycle, but if you have been using gear around 500mg per hormone, about 2 hormones per cycle, then I could see going to 750 test, 600-700 EQ and about 30mg Dbol. If your goal is to gain mass, I would go Dbol, not Var. Var is goold for strength and good for a cutting diet, but you aren't going to get the size you will from something like Dbol. Because EQ has such a long ester, I would run your cycle a little longer, around 16 wks, along with the test, and use the dbol for about the first 6 wks. That will be a great way to kick start the mass gains and help you start pushing heavier weight.
The higher the dose of EQ, the more likely you will need to give blood. I find especially that at 800mg or above, hemoglobin can get pretty higher after a couple of months. Watch yourself.
