Aromatase Questions – Feeling Low E2 on Current Protocol

[fw190jd]

Hey everyone,


I’m a heavy aromatizer and currently working with a coach, but I wanted to get some community insight.


I’m on exemestane, total 212.5 mg/week, split like this: 112.5 → 62.5 → 37.5. My most recent E2 came in at 152 last BW is promted my coach on this heavy protocol , , but I feel like this protocol might be overkill.


Since starting it, by 4 weeks lately I’ve noticed some classic low-E2 symptoms:

Just went for BW last Thursday for sensitive E2

• Joint pain
• Mood swings
• Libido issues
• Morning wood gone

For context, I’m running:

• 575 mg/week of testosterone
• 500 Primo
• 240 mg/week of NPP
• Pre-workout with ~75 mg of TNE

I feel like something like 12.5 mg every other day could have been plenty. I love my current stack, but right now I feel like I’m edging toward an E2 crash.


Has anyone with heavy aromatization experience run something more conservative like this? How did it affect E2 and symptoms?

Thank you in advance

What's your body comp look like?

E2 is not useless. You should use AIs according to bloodwork, not just symptoms.

Hi,
9% BF, weight 179 and climbing coming to the end of a bulk in 2 weeks, look good happy with the progress so far.

So I have never used an AI so I won't be any help there. But the reason I've never needed one is because I run dry compounds alongside test. I see you're running primo which should help a bit with aromatization. Have you considered lowering the test and adding something like mast or EQ?

Most people would Not need an AI on that stack given the ratio of test to primo. This is something that needs bloodwork. Can’t go by feels.

At what point did you get that first bloodwork? The primo AI effects can take weeks to materialize. I made this error also when I added primo to my test cycle and felt as if it wasn’t doing anything and then 3 weeks later my E2 was 18.

Also, are those aromasin dosages typos? 200 mg?

no typos

I don’t think I’ve ever seen anything like that in terms of AI dosing. I probably would have repeated the estrogen labs before making any intervention. It sounds like you may have crashed your estrogen with the combo of what you’re taking.

Yes, should have the latest labs in the next day or two, in the meantime I'm just holding off on any AI until I can see what the BW says.

 

[fw190jd]

well, thats that

Do you trust your source on the exemestane?

Your bloodwork looks like I'd expect just on that dose of test and primo.

200mg+ of exemestane would have it in low single digits tops.

 

[fw190jd]

yes I do trust the source as being a little underdosed which puts me exactly where I'm at. the other concerning point is my blood work has my prolactin at 57 and I asked my coach if I should introduce some caber ,. 25 mg 2week,for a couple weeks 4 to 6 weeks and then retest just to get that number down and he said don't worry about it just leave it alone. so I'm a little confused as you can understand why I would ignore my prolactin and also be on 200 mg of AI this is the second time my AI crashed with this coach

Mate i gotta tell you, that is the dumbest fucking stack I've seen and it's very obvious you haven't titrated anything.

Start over, let everything wash out and layer in your extra compounds 100mg at a time, get your blood work every 8 weeks and properly learn how you respond to this stuff.

200mg aromasin, 500 primo and you're considering caber? Really? Nobody here is gonna have a clue what's driving your shit up if you don't.

Also the total mg you're running to be 179 lbs is absolute overkill, you can achieve that natty without needing to pump a gram.

Thanks, did you read the earlier part of this thread ?
This is what my coach has me one, labs just came in and E2 is at 14 so I'm dropping the primo and raising the test c to 700 mg per week for 2x weeks to build estrogen back up as well as use TNE prework.
Check labs in 2x weeks and if prolactin is sitll elevated and E2 has normalized then I would add a lose dose caber for 2weeks and check labs. . And dropped the coach.

Fire your coach

 

[fw190jd]

yes, I mean what's the point, I'll just manage it myself with the help of the form members that's it it's not rocket science

I don't know the credentials of your coach, so I won't speak negatively. But I will say it appears you're wasting your time (priceless), and money on that coach.

Get complete labs done. Everything.

Or best drop everything but T, and wait 10-12 weeks. See if you feel better, but then still get labs.

thanks guys appreciate your help , I've already made my adjustments I have to finish up this blasting a 3 weeks left to go to my bulk and then I'm going to go into a tie right down to a cruise I just got tripped up with this E2 and prolactin keep you posted Rock on

Be warned that just because someone achieved very well personally (survivor bias) does not mean they know how to recreate it in others.

Social media is an absolute septic tank full of grifters

I want to put this into proper perspective.


When I decided to work with a coach, I looked at several options. I ultimately chose this one because of their credentials and experience, and because I had some very clear ambitions. I wasn’t dabbling — I had a real vision of where I wanted to be in 18 months to two years. I knew I was already three years into training, but I figured that with the right guidance, another two years could potentially put me in a position to be stage-ready for a Masters division. I also understood that meant I still needed to add a significant amount of size, and that timeline might be tight — but that was the goal.


Because of that, I made a conscious decision to trust someone on that journey.


Early on, some of the protocols felt aggressive, especially on the drug side. But when you put your trust in a coach, you assume they may know something you don’t — or see the bigger picture differently. So you take it step by step. The results started coming, performance improved, and the blood work, while not perfect, was generally clean. Liver enzymes were a bit elevated, HDL was a little off — but nothing at a dangerous level, and nothing unexpected given the circumstances. That always gave me some reassurance, even if some of the doses felt higher than I would’ve chosen on my own.


Where my concern really started was toward the later stages.


That’s when the question marks began to add up — specifically around AI management and the lack of adjustment despite prolactin being elevated. That part was disappointing. At that point, it felt less like fine-tuning and more like things were being overlooked.


That’s ultimately why I started this thread. I’m not here to bash anyone. I just want to hear what others think, especially from people who’ve been through similar situations or have a deeper understanding of this side of the process.


I appreciate any insight you guys have.
