Gyno incomming,

Hi guys, my first post here, in desperate need of some good advice.

192cm
102kg
26 Years old
I have done 3 cycle to date.

I am 5 Weeks into cycle.

I am currently running:
Test E 600mg 15 weeks
Mk677 15mg 15 weeks
Proviron 60mg 8 weeks
Superdrol 20mg 6 weeks (First and last time using SD!)

This is along with Essentiale everyday and Liv 52 support, Zinc, omega 3+6 etc..

I crashed my estrogen 2 weeks into cycle, 0,5 mg arimidex every fourth day when injecting.

Only tested for Estrogen end of week 3, doctor said it was lower than 70 which is fine apparently.

I stopped using arimidex on day 14 till now at day 30 +-.

I feel a very clear lump under left nipple growing, almost rapidly.I felt the lump before I started my cycle, was probably because of a previous cycle.Previous cycles only consisted of Test E 8 weeks and 1 oral sarm like Rad.
Nips are also puffy now, appearance still looks okayish,BF is around 14%.
What am I doing wrong for lumps to be growing with low/normal E?

Estrogen rebound because of not using Arimidex for a while?
SD causing lumps/gyno?
MK677 causing lumps to grow?

From what I have read on the forums, the brands I am using are the best in the business and highly reputable.

That is all I can think of, please inform me if you guys want more information.
Thank you everyone for reading and if applicable thank you for your responses.

well, what was your previous dosing of test e, and where there signs of gyno then? how do you know you crashed your e2? where are your blood to substantiate this, and how do you feel as if you crashed e2?

after 2 weeks yes you may have used it prematurely, but at the same time, I want to see the justification of the crashed estrogen.

you might find your test dosing is just too high for you and that is why you are getting gyno. some guys get gyno from TRT dosing, some dont.

Previous dose was 500mg a week. No signs of Gyno back then.
Extreme joint pain in elbows and in knees, some pain in hips too. And also just feeling like a zombie. A week after that started, I did my bloods, report just said my Estrogen was less than <70.
Currently all joints are fine and no more pain, so my Estrogen got back up I assume, but lumps started well before I had joint pain.
I am doing 600mg Test E a week now.

Gyno is best treated with bloods. Also probably wise to stop the superdrol. I will never try treat gyno with these crazy protocols, you land up feeling like death and achieve little to no reversal effect.
