TRT Advice Please: High Oestrogen and Possible Gyno

[Sebonacci]

Hi guys, hope everyone is well.


I’m looking for some advice regarding my TRT protocol, high oestrogen and possible gyno.


I started TRT at the end of March 2026. Im now 46 years old, 6ft tall and 190lb at approx 15-20% body fat

Blood results​

Marker	Before TRT 4 Feb	On TRT 15 June
Total Testosterone	12.5 nmol/L	26.0 nmol/L
Free Testosterone	0.26 nmol/L	0.6036 nmol/L
Oestradiol E2	Not tested	297 pmol/L HIGH
SHBG	28 nmol/L	28.9 nmol/L
Prolactin	Not tested	247 mIU/L
Haematocrit	Not tested	48.5%
Haemoglobin	Not tested	159 g/L

My June E2 was 297 pmol/L, with the male reference range being 41.4 to 159 pmol/L. My testosterone and free testosterone had also increased considerably.


At that point I didn't have nipple pain or sensitivity, although I had developed acne across my shoulders.


I already had some fat around my chest before TRT. Despite losing weight and gaining muscle, my chest hasn't really leaned out and the area around my nipples actually looks a little puffier.


At the time of my June blood test I was taking approximately 128 mg testosterone cypionate per week, split into two injections.


On 10 August 2026, I changed to more frequent injections because I wanted to reduce the hormonal peaks to hopefully reduce the high estrogen


I also started taking DIM and reduced my overall testosterone dose.

Current protocol​

Monday: 0.12 mL which is 24 mg
Wednesday: 0.16 mL which is 32 mg
Friday: 0.16 mL which is 32 mg
Sunday: 0.12 mL which is 24 mg


Total: 112 mg per week


Testosterone concentration is 200 mg per mL.


I use slightly smaller injections on Sunday and Monday because those injections fall on consecutive days.


Since making these changes, my shoulder acne has cleared up, which makes me think the lower dose and more frequent injections are helping to some extent.


I was also planning to switch from testosterone cypionate to testosterone enanthate soon.


The reason I'm asking for advice now is that today I noticed sensitivity in one nipple for the first time.


Considering my E2 was already 297 pmol/L in June, I'm concerned that this could now be early gyno rather than simply the chest fat and puffiness I already had.

What would you guys do?​

1. Would you give the current 112 mg protocol more time considering I've been using the more frequent injections since 10 August?
2. Would you get another blood test now rather than waiting until my planned test on 5 October?
3. With nipple sensitivity now appearing, would you consider a low dose aromatase inhibitor or wait for another E2 result first?
4. If this is very early gyno, can getting the oestrogen under control cause the sensitivity and puffiness to regress or will it just stop it getting worse?
5. Would you hold off switching from Test C to Test E for now so I'm not changing several things at once?

I'm not looking to crash my oestrogen or start taking unnecessary medication. I just want to get my TRT balanced and deal with this early if it genuinely is the start of gyno.


I know many people here must have dealt with this situation before, and I’d love to hear what you did about it. Any help and advice would be truly appreciated.


Thanks guys.

My e2 was pretty high last labs, but not as high as yours. I did end up starting an AI, very low dose. I'm taking .25mg arimidex twice weekly. Only 1/4 pill each dose. I will need to recheck bloods soon, but i can tell you i definitely have not crashed my e2. I feel great. Just the trick is that you start very low and see how it affects you. Maybe I'll need to up the dose, maybe not, but not crashing it is key. Even if i do need to up it at some point, it's still an improvement over what it was at

Make sure you order the sensitive estradiol test by mass spectrometry. The eclia one is really not accurate at all. It your levels are real you could add a small dose of an ai but you don't want to crash it. That would suck worse than being hypogonadal. You could use one while you try to clean up your diet and drop some body fat. Those will naturally drop your E2 significantly. But retest using the sensitive test. Sounds like your E2 is high based on side effects. If you want to stay away from AIs (I do) then nolvadex would work without starving most of your tissues of E2.

get bloods sooner rather than waiting until Oct 5. Look into tamoxifen to stop tissue progression

Your body didn't make enough testosterone so you added some, your body makes too much estrogen so add something to lower it, use an aromatase inhibitor, don't be scared. The poison is in the dose

Thanks guys.

Youre at 81 pg/ml E2...thats not insanely high but if youre having sides or gyno flair you need to reign it in. You do that with an AI, its not "unnecessary" medication if youre treating a condition and the medicine is necessary to do that. So get over the stigma and take an AI. I see ppl telling you to take Tamoxifen since you don't want to take an AI which is ridiculous being as how tamoxifen is more harsh and doesnt treat the root cause of the issue. You need 12.5mg of Aromasin 2x a week until you get e2 within range or stop having symptoms. Only take Nolvadex if you have a palpable nodule under the nipple. Sensitive nips is a warning sign of gyno not gyno itself. Since you have nothing on hand, foolish tbh, but since you don't ordering a bandaid isnt the answer. Buy the medicine to treat the root cause. Aromasin 25mg available from almost all sponsors here. Take it for 2 weeks and retest ultrasensitive estradiol. You wont crash your e2 at that dose of aromasin its forgiving. Youre obviously a high aromatizer so youre going to have to take something for it. If youre genuinely at 15% bodyfat then thats not to blame you just aromatize heavily. So your choices are an AI, grow tits, or drop the test. I would take the damn AI

To be clear, you'll be able to drop the aromasin dose down after the flare/sides are gone. You may even be able to drop it to 12.5mg every other week after implementing daily injections, sharpening diet and losing more bf. Only BW can say for sure... But for now you need it. It would benefit you from now on to preemptively mitigate potential sides by having things like Nolvadex(tamoxifen) and other ancillaries on hand. Especially if you plan on ever upping the dose or running a cycle. Dont let yourself get in this position again over a $30 bottle of pills.

Bro thanks for this,
my diet is super clean so ill continue with that and get some Aromasin, ill order it right now, ill start with the 12.5mg 2x a week. ill take for 2 weeks and retest ultrasensitive estradiol

should I order some Nolvadex aswell to keep on hand? what scenario is it used in?

Yes it would be smart. Nolvadex nukes gyno, its a serm. (Selective estrogen receptor modulator) it stops estrogen effect on breast tissue in its tracks. But it doesn't directly lower serum e2 levels. Which is why its not the answer to your issue since you dint have gyno, just early warning signs. But yes grab some, if for no other reason then piece of mind youll never grow tits. Gyno from high e2 shows as a pea sized nodule behind the nipple. Thats when you take nolva. Or if you KNOW the sensitivity is bad enough that a nodule is imminent. Or if youre juggling compounds on a large cycle but thats not your problem atm. To check FOR a nodule lift your arm elbow bent and behind your head, stretching the pec/chest flat then use your other hand to palpate the area behind the nipple. A nodule will feel like a rubbery pea. If you have that, take nolvadex. Idk where youre at in the world but if youre in the states @GYMnTONIC has what you need and has no minimum order and is very fast. When you search search by Exemestane (aromasins other name)

I cant feel anything when arm is in normal position but ive just done the lift my arm check you described and i can feel a little something in the most sensitive part

Do I take Nolva and then switch to Aromasin or take both at the same time?

You can take both concurrently. But be sure its a nodule. Like I said pea sized rubbery nodule. Its not going to hurt you to do a short run of tamoxifen while you lower the estrogen either way. Just take 20mg ed of the tamoxifen for a couple weeks it doesn't work overnight. If you dont see improvement in shrinking what you feel in 2 weeks its either not gyno or its already permanent(possibly even from puberty). Dont be alarmed either way, if you can't feel it normally its likely not visible or going to be a real issue. I have a very tiny permanent nodule in my right side that isnt visible and only palpable with my arm lifted.

 

[Sebonacci]

Ok ive just ordered from GenLabs as im in the uk - ill start with the 12.5mg Aromasin 2x a week and 20mg Nolvadex

Thanks so much for your help I really apreciate it

im really happy with my body and gains thus far its just these tits man, I gotta get them off me

Lol that sounds like a good goal. Good luck

as a pea sized nodule behind the nipple

As in literally behind the nipple or within the areola range?

I'm not sure if I'm having the same issue and reading posts and comments is giving me hypochondria that I might have this, overthinking it. Nips aren't sensitive, as in when I wear clothing or anything rubs up against them, I don't feel anything. When I press them, feels more sensitive, the good kind (heh) than usual, however not painful. I did the arm test and feel something lumpy but in the areola range, not directly behind the nipple. Not sure if that's legit or just something I've had.
