There seems to be a lot of differing opinions in regard to Tren and possible gyno from its use. Here is a quote from Bill Roberts....
"The only reference I know of discussing prolactin with regard to trenbolone administration (Res Vet Sci 1981 Jan;30(10:7-13) says that prolactin DID NOT increase on trenbolone administration.
Proof of binding to a receptor(PR) is not proof of activity. For example, ANTAGONISTS bind well to a receptor but don't have activity.
The only reference I have read discussing whether or not trenbolone(as opposed to a very different compound, "allyl trenbolone") has progestagenic activity was that it does not, in the veterinary literature.
Highly gyno-prone individuals use injectable trenbolone acetate all the time and love the stuff. I couldn't begin to count how many, and myself, have zero reports of anyone getting gyno from injectable TA." Bill Roberts
