Very interesting, Magician! I knew Nandrolone upregulates Aromatase but I never knew it was by as much as 40% increase in rate of aromatisation!! Crazy!

I'm dropping deca now, replaced it with tri bold

As for OP, it really could be estrogen. I have never had issues with deca dick and I have blasted deca as high as gram with 300 test no AI no problems with penis.


My friends have run deca solo, no issues either with sex drive or penis
