Order the male or female blood hormon panel, both include test and e2. Male includes igf, a full blood workup, thyroid etc so IMO worth the extra.
If estrogen is abound mid 20s it's high, bring lab work to dr and request AI. If he won't do it then many online "research" sites carry them. If is high lowering it will increase test.
Since you self pin 150mg week / 7 days = 21.41 x 4 = 85mg
Take 85-90mg every 84 hrs or once every 4 days. The end result is still your scripted 150mg week but you will have much more stable blood levels and less of a drop off at week end. I know someone that does 100mg (close to your script) every 4 days and his levels are ALWAYS 1200-1300 on the 4th day before the next pin.
So: test AI and get if needed
Pin more often
If you don't like pinning. I can explain out to backload a 29g 1/2" slin pin after you draw fron the vial with your normal 22-23g pin and then pin intermuscle in lean areas with that (what I do). Totally painless and no scar tissue build up over time.
