I wonder how many people get limp dick from alcohol, cocaine, ecstacy, etc. and instead blame it on Deca?
Yes. I know many treat their "Deca dick" with Viagra or Cialis and it works. Doesn't mean Deca is increasing their PDE5 levels.Adding test to Deca will most likely increase prolactin since the estrogen from aromatization will increase prolactin (and androgens will lower it). My guess is that Deca is just too weak an androgen to "drive" libido or it doesn't have the necessary neural effects for libido.Of course, prolactin and progesterone agonism could be part of it but who knows for sure?
