Yes you could add Masteron to your stack, it acts as an anti-e also, but because it is a DHT derivative it's hard on the Hair and the prostate, but it doesn't cause water retention so BP wouldn't be an issue. Here is something to think about, 30mg of d-bol weekly rivals 400mg of test weekly, this is striahgt out of CME. Plus you don't have to use huge doses, like for a beginner something like this: Week 1: 20mg Week 2: 25mg Week 3: 30mg Week 4: 25mg Week 6: 20mg. Even 10mg of D-bol a day is potent, their is a reason they used to call it the breakfast of Champions! lol. And the use of Femara or Aromasin would be helpful to eliminate excess water therefore lowering blood pressure. As for the more advanced athlete doses of D-bol should be 5mg per 25lbs of bodyweight, so for a 200lber that's 40mg daily. And Femara or Amromasin would be a good idea for use with the D-bol because of it's ability to aromatise into a supergirl like estrogen. And like i said get your blood work done, check your bp also, if you find your BP is sky high, i suggest you search on here for a way to lower it, i read something on here a while back, about a stack of supplements that lowered your BP significantly, so that would be very helpful. Another thing to keep inmind is that a stack of multiple compounds (3 or more) in low doses is more potent than just 1 or 2 compounds in high doses, so their is more room to play with your doses in the future. So by using Test, eq, deca and d-bol you only need to use minimal doses. I'd say run the test/eq/d-bol then drop the eq and replace it with the Deca, switching up the compounds will be more effective than just running them all at once.
