Gotcha! So it in theory it will breakdown into Phera or "madol" in the body and the 2-cyano is the "legal" way to get around the previous 17a-methyl bond? I apologies for my ignorance and understand if you dont want to give a chemistry lesson.
No it is a different compound with a similar chemical structure to phera.
As far as I know when dealing with prosteroids or prohormone's there are only 2 enzyme's that do conversion.
A good majority of the steroids on the market all utilize a 3 ketone group(double bonded oxygen at the 3rd carbon in the A ring) and a 17 beta hydroxyl group(single bonded OH at the 17 beta positon in the D ring) which is a functional alcohol group.
Ketone groups are represented in chemical nomenclature as one or on, or for multiple groups dione(2) and trione(3).
Hydroxyl group's you will either see represented in the begining of the chemical nomenclasture as Hydroxy or at the end of the of it as ol, or diol(2), or triol(3).
Since were on the topic I'll throw this in. Anyway the last part of the the chemical nomenclature you see in the middle is either androstane or androsten. Ane means there are no double bonded carbon's in the structure, Ene or En specify double bonds. So like for Dihydrotestosterone based you might see it represented as 5a-androstane or Androstane which just means that there is a 5 alpha carbon instead of a 4-5 double bond, for testosterone based you would see 4-Androstene or Androst-4-en, same goes dien 2, trien 3.
Point in case prostetroids are usually either dione or diol precursers which means either 3,17 have ketone groups, or 3,17 have hydroxy groups. In which your body will either add a hydrogen to the 17th ketone to make a hydroxy, or strip a hydrogen at the 3 hydroxy to make a ketone.
Like the old tren products were actually Dienedione if you break that name down, it basically means 2 double bonds diene, 2 ketones dione, with the target active being dienolone or 2 double bonds dien, 1 hydroxy ol, 1 ketone one.
1-AD aka 1-Androstenediol is the diol precursor to 1-testosterone.
4-AD aka 4-Androstenediol is the diol precursor to testosterone.
1,4AD aka 1-4 Androstenedione/boldione is the dione precursor to Boldenone
M1,4AD is the Diol precursor to Dianabol which is just 17a methylated boldenone, hence forth the M before the 1,4AD
You get the picture.
