Where to start...
Deca DOES NOT aromatize to Progesterone, but can to dihydronandrolone, which is a weak AR agonist. Deca is also weakend by the 5AR
Nandrolone is PR agonistic, and the PR can alter its structure. (This is where the myth of Deca>Progesterone comes from..not really, its more like a wanna be progesterone, but seems to act somewhat like progesterone). Progesterone is an E2 agonist, and believed by many also a prolactin agonist (this is why many take bromo or dostinex for deca and fina).
Both prolactin and progesteron receptors can be found in the mammary gland and can cause gyno, but it is rarer than from estrogen. IGF-1 can also cause gyno, and most AAS raise levels.
So if you take an anti-e, it can help. As I just said, Prog is an E2 agonist which could lead to gyno, lower the E2 lower the chances of that happening.
There is also the explanation (which seems rather fictional to me) that since anti-e slightly lower IGF-1, this can help fight gyno.
Since Prog may be a Prolactin agonist, Cabergoline (dostinex) may block that area.
Then there is the winstrol debate. Winny does bind with the PR and may block it. Problems is, nobody really knows wether nandrolone or winny has the highest affinity to it. Thats kinda a cross your fingers protection.
Bromo sucks. Dostinex is so much better.
Dostinex with Aromasin and you should have no worries about any gyno caused by 19nor substances.
Sorry if I dont post my sources, but this is pretty much common knowledge from the field I study and I just dont feel like it to be honest.
My advice, when lookin up answers, you have to stay away from biased sites. Especially ones on HRT...so much incorrect stuff its pathetic
