but it makes sense, ppl hold water on test..ppl hold more water on test + deca..but deca solo is little water like eq
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
U mentioned that u used letro
I can say 100% that too low estrogen makes your dick not respond no any sexual stimulation, maybe u lwoered it too much
do you have any low estro symptoms? it could be not problem from deca but from estrogen (too low or too high)
too many things bad about letro
I would drop it and use calcium d glucirate itll give you normal estrogen balance,
"Also ever took letro and still had nipple sentivity? Wonder why? Letro lowers shgb dramatically this allows free testosterone to spike and as a result free estrogen, this is the reason the letro gyno reversal protocol doesn?t work"
drop test and use more deca. keep estro in check and you wont have prolactin issues. test is the problem maker
