trenbolone precursor?

[genesis1]

After 9 years of training, I have pretty good physique, but like any typical bodybuilder, I WANT MORE! so, I decided to take my physique
to the next level.
Since i have never did any cycle and ph/steroids are banned, I did some research finding "Estra-4, 9-diene-3, 17-dione" (find in testranflex, finigenx...).

It supposed to be some kind of trenbolone precursor.
i tried to find out information about this ingredient, his anabolic potential, side effects, pct and so, but all i can find are commercial information and personal irrelevant opinions (from people that thinking that bodybuilding comes in magic pill...)

I need some established information.
help is needed.
