Hey Test,

This may be individual, but I was on a similar cycle of 150T/500primo/50var and I ran bloods and found my total T at 561 but my sensitive E2 extremely low at 4.8. Another time I ran bloods on test only my T was 1473 and my E2 at 36.4

It's been stated by respected members here that I may be a low E2 converter BUT i wonder...if primo has an effect on lowering E2 OTHER than the anti-estrogenic properties it is said to have. Point being, if you were me, taking an AI would not be a good plan. Interested if you've run bloods on a test/primo cycle previously.
