Primo vs mast mental effects

Hey guys, I’m currently on test/mast/deca. I’m considering swapping out the mast for primo cus I need something with stronger anti estrogenic effects. I’ve only used primo once at a low dose and don’t really remember how it made me feel. All I recall is that it lowered my e2 and had some positive effects on mood. Mast gives me a nice boost to mood, I’m calmer, happier, highly motivated, feel sharper mentally, and have stupid high libido. Little hesitant to drop mast cus of how great it makes me feel. I’m curious about experiences with mast vs primo in terms of their mental effects.

Why do you need something with “stronger anti estrogenic effects”? Is this based on feels or verified by blood work?

If it’s the former, I would consider staying the course based on how well mast is clearly treating you. Don’t fix it if it ain’t broke.

If it’s the latter, I’d opt to run a dedicated AI, not use primo in place of one.

E2 was elevated before I added the mast, getting more bloods tomorrow. I was considering keeping everything the same and adding some asin but primo just felt more stable from what I recall in comparison to asin and adex.

What was E2? What is your current cycle?

so I was originally on 150mg test with 600mg deca and my e2 was at 55pg/ml. Was getting high e2 sides and also sides probably from lack of androgens. Now I’m currently on 300mg test, 300mg mast, 300 deca.

That E2 is fine in my book, shouldn’t be causing sides imo.

Did you check prolactin last blood work?

No I didn’t, I am getting it checked tomorrow tho. I was getting obvious high e2 sides like crying from tv shows. 19nors seem to make me more sensitive to high e2 without raising it on paper like tren or raising it a little like nand seems to do.

Nothing wrong with crying from TV shows. I've been doing that my whole life! Just started trt at 37 about 2 years ago
 
Masteron I felt neutral, slightly more balanced when it comes to hormones and estrogen.

On the other hand on primo I felt good at first and then so tired, kinda drained energy and angry for some bs too. Down and depressed. Not cool in my book.

So for me Test is best, but if there are some shit I wouldn't ever touch again it's primo.

Primo exerts more of its antiestrogenic effect by inhibiting aromatase (reflected on bloodwork) vs Mast’s more tissue-level blockade of estrogen uptake, but both do both. Note, however, that there is substantial inter- and even intra- individual variation in each drug’s potency to inhibit aromatase for reasons given in Primobolan / Equipoise Crashed my E2 – Help!

I agree that Mast is more androgenic and promotes mood, energy, and well-being better than Primo that can almost blunt it in some cases.
 
IMO if you’re trying to manage an already unmanaged e2 use an AI, the effect is very predictable and fast. If your e2 is already managed with an AI and you’d like to try swapping out the AI with primo or eq then start slow. What you don’t want to do is try to get unmanaged e2 under control without knowing the effect of primo or eq on your e2.

As far as feels, mast feels great, I don’t get that feeling with primo.

Highly interesting on how everyones "mental" experience is different. 80-90% of the time being on Test+Primo is what makes me feel the best.

On a cut I might tend to be more short tempered on Primo, less tolerant for bullshit and slightly more agitated. But Id say the caloric deficit plays the biggest role on it.

However, Test / Primo 1:1 is cutting my e2 by half on bloodwork. Thats also my red line using those two compounds together. Can be too low for the mental effects so I either up the test a little or bring down the Primo and all goes perfectly well again.

Test only a little too high makes me feel like shit (I dont experience physical e2 issues but I am aromatizing quite alot on bloodwork - low end of shbg by default also plays a role here for me).

Skin: No issues entirely. Had heavy acne during puberty (just on upper back tho, but pretty heavy). Not oily, nothing.

Never used mast so far, so I cannot contribute to that.

Didn't realize how crappy primo made me feel until I came off and all of a sudden I wasn't irritable and down all the time. Also reduces my libido.

I know people are going to say it was from lowered E2 but I had it tested multiple times and no matter what the level, the same feelings applied.
