Estrogen conversion rate
Can your body’s estrogen conversion rate change over time? I’ve been on 200mg/week of test for almost 2 years. 1 mg adex used to put my e2 on mid 20’s until it crashed. Then i switched to .5 and it was good for a while. Now it seems like .5 adex is too much. Nothing has really changed, BF remains the same, if anything i might have gained a little fat the last couple of months.
Could be different purity levels on the products you’re using, could be the fat gain, could be your diet, could be as little as that you took some extra vitamins.
Basically: Thousands of different factors could result in this, yes
