For starters nothing about masteron is going to help you bulk, tbh I try and look at masteron the same as proviron just injectable.
Next, your base is a short Easter test. Look at your base like a foundation of a building. Your building is going to be stronger if the foundation is bigger. Meaning a longer Easter. Enanthate or cypionate should do the job. I personal like Sustanon, it's a blend of short and long esters. I feel better on it. I would strip eq out of the equation. It takes to long to really see any effects from it. I would honestly just run 500-600mg of test E or 500mg or Sustanon run proviron at 50mg Ed. Proviron is great it is completely underrated. It bing to SBHG to help increase your free testosterone. That's the number you want more of. Hopefully you understand what I am talking about. If not, u probably should educate yourself more before beginning. This recommendation should get you big and lean, the amount of water you hold will be based on estrogen control and diet. Hope this helps.
If you wanted masteron because you felt that it was gonna lean you out, you are wrong. For something like that you could get some Winstrol and run it @ 50mg Ed for the last 4-6 weeks of your cycle. The nice think about Test only is that you can run it for 8-12 wks. Pull bloods after a month and if everything is in check. You are good the rest of the cycle. No need to keep pulling bloods. The more gear, the more moving pieces. If something happens, then shit gets more complicated. You don't want that.
