Very infrequent poster, but Ive had similar issues and will tell you how Ive fixed this for myself.
1. Use TE. Short esters cause more issues since they are hard to keep levels steady. TE is best. I also feel like faster test esters cause a little more hyper tension. Ime. TNE, for instance, I can almost immediately feel that pressure go up in my face and around my neck. At first I thought it was an allergic reaction.
2. This is the most important part. You gotta pin daily. I went from doing 2 pins/wk at 150mg with 1-1.5mg of Adex/week, to about 200mg TE with 1500HCG/wk with the very occassional Adex dose. HCG for fertility. E2 tested at 32.
3. Primo will definitely lower your E2. I was using 500TE/wk and my E2 came in over 200. Added 300 primo and it brought it down to normal range, BP was only slightly elevated there. 5/3 test/primo ratio has kept me AI free at every dose Ive tried. That 500T was my very first time using primo. Ive kept the same ratio basically for some time.
4. Mast will not lower E2, but it does act SERMish in that you may still have high E2, but wont get gyno or limp dick if the dose is right. Also seems to reduce the increased aldosterone effect that elevated test has, which is why its considered a 'dry' steroid. Ive not noticed Primo do this. Primo isnt 'dry', its just not as wet as test is, since it drops thr E2 water retention, but aldosterone also raises intramuscular water retention, which helps with strength and fullness.
Agree with the above comment about the body getting used to this stuff. Youll find your base dose and learn to go up from there.
