Ok then, this is for sure M-diene.
Chemical name:
17a-methyl-17beta-hydroxyestra-4,9(10)dien-3-one
This is similar to methyltren, which is:
17a-methyl-17beta-hydroxyestra-4,9,11-trien-3-one
And similar to Finigenix:
estra-4,9-dien-3,17-dione
From my understanding, it's a so-so PH. Some people liked it, some noticed nothing more than a slight decrease in wallet size, and some have had NASTY side effects.
