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?
Good stuff, man. All I've got to say about deca and tren is to start off slow. Both are awesome steroids and if you run more test than the abovementioned, you'll likely be fine. Keep some proviron on hand if you wish. If your libido absolutely hits the floor, grab some Cialis or Viagra. The worst thing is coming off cycle, getting lethargic, depressed and having your girlfriend have to put up with getting soft dicked once a week after being ravaged on cycle.
I'm finishing up 8 weeks of tren, just 50mg EOD but damn was it good. Sweat like a pig at night, slayed the weights in the gym, no fits of rage, great body recomposition, sky high sex drive... but if my libido goes to shit, I'll pick up some Cialis for however long it lasts. Just gonna split a bottle with a buddy. I swear, my gf must be stealing my juice or something because even at the pinnacle of hornyness, my gf's sex drive is STILL higher than mine. Last thing I want to do is end up having to soft dick my nympho gf. It's one thing to put up with a bf who cycle's steroids but for it to cut into your sexual life is just too much to ask a girl to put up with. Make sure to research your compounds and plan ahead boys!!! Ain't NO girl out there who wants to get soft dicked.
