Is it really? Interesting lets see..after googling and searching the first time (then reading your comment were you infer that I didn't search to begin with, and doing it again) this is what I found.
Finigenix Magnum
Innovators: PharmagenX
Nomenclature: Estra-4, 9-diene-3, 17-dione
Dosages: 50-75mg
Side effects: aggrevation of gynecomastia. This is a progestin. Expect tren-like sides.
Reputation: This is a prohormone to dienolone (similar to M-diene). Decent for recomp and increases in strength.
So Estra-4, 9-diene-3, 17-dione = 19-Norandrosta-4, 9-diene-3,17-dione?
People use to make the WRONG assumption about Promagnum-25 and Halodrol 50, they assumed they were the same because they have a nomenclature that is almost IDENTICAL yet they are derivatives to of steroids. I'm not a chemist, but would you educate us and care to explain how a Estra-4, 9-diene-3, 17-dione = 19-Norandrosta-4, 9-diene-3,17-dione?
