I think this is a uncommon stuff and it only happens for those who already have very active 5ar1 naturally(I got this confirmed), so when there is no androgen signaling due to oversupression with e2,dutasteride and bica, body tries to get androgens desperately to compensate the loss (similar stuff happens when you take bica without stopping HPG Axis with progestagens or high estradiol levels, your body tries to compensate the lost of Testosterone producing it in more quantity). How can does the body achieve androgen signaling with every androgen supressed as hell and also a supressed HPG Axis? Correct by 5ar overproduction. Since T is already supressed, 5ar2 is useless so T can't increase much the DHT. For those with very active 5ar1 all the androstenedione which is produced in higer quantites on the adrenal glands, most of that androstenedione start to convert into DHT by 5ar1. Since bica can't stop 5ar and dutas only inhibit 50% of the 5ar1 with the standard 0.5 mg dosage, the body has a room to upregulate that 50% left that is not inhibited by anything. That is why my DHT increased on the first place I'm now 100% sure after several blood test and that is why my DHT came back at 3.5 ng/dl now that I use between 4.5 to 5 mg dutasteride daily. It is not a coincidence that on december last year I had very low DHT(4.5 ng/dl) and after using daily bica my DHT on march 2024 started to rise to 18 and then 21 ng/dl in June and stayed like that till this last blood test done last week(which came back at 3.5 ng/dl) after keeping doing blood test on august, september and october to see if the DHT was lower, but it wasn't.
