Running Primo and Mast with TRT?

I’ve been running Mast E with my Test C TRT dose for a while(150/150 week) and have been loving the results since adding it in. I like the hardness and vascularity it has added and don’t want to lose that look but my E2 is creeping again and would like to avoid the AI because my lipids are always right on the edge of being out of range. I’d like to try Primo to lower the E2 but don’t want to drop the Mast. Are Mast and Primo a one or other situation? Any disadvantages of running both? Could I split the dose and run like a 150Test/75mast/75primo or would that just limit the benefits of both?
 
If your E2 is high you can add primo without lowering or dropping your mast.

How about the Test? Does that need to be lowered, or is it advisable to keep it higher, so the mast and primo can do their thing.

I’m not an expert, but I’d say PBZ will want to keep his testosterone at the current dosage. I could be wrong.
@PBZ researching Mast, many people say you should run it at a low body fat percentage to see true results. If you don’t mind sharing, what is your current body fat percentage?

That goes for every compound if you are wanting to see the true cosmetic effects of them.

Hard to say. Somewhere between 12-15%. Arms and legs are lean, top 4 abs have good separation but the loose skin from once being 100lbs heavier keeps the lower abs from being in.

If you are worried about your lipids, adding more mg of anabolics is going to make that harder to manage.

Could try something like 150test/100primo/100 mast is a really nice trt++.
 
My favorite Summer blast is Test/Primo/Mast, and I've been running it every Summer for the last several years. Unfortunately, I just found out that I have prostate cancer, so I won't be running that this Summer lol. However, if I get my prostate removed like my urologist recommends.....it's on next Summer!

Sorry to hear that, best of luck to you!

Ive been running trt++ for about 4 months. All my labs look great ( I eat very clean and do about 200-250 minutes zone 2 cardio every week religiously). Im on 350 test c, 300 primo, 100mg mast, split twice a week. I feel amazing, no hair shedding, always ready to split my gf cheeks. I aromatize a lot despite low bf. I still have to do a out 6.25 aromasin every couple weeks.

I almost always run Mast with my primo. Just did 400mg Test, 600mg Primo 300 Mast. Had to up test, lower Primo and Mast as my E2 went down to 13.5.

I can’t let my E2 go that low. I got it back down to the 20’s for a bit and my libido really took a hit. Mid 30’s seems to be the sweet spot for where I keep my total T.

I have had it as low as 3.5. I thought I was taking Primo, but a Vendor on here had Mast E in the vial and I was doing 800 mg/week of Mast.
