If Primobolan is a Methylated Compound does that mean its Liver Toxic ?

1-Methyl-5α-androst-1-en-17β-ol-3-one
Ah yes, sort of sure
Here we can see a comparative study in 38 male subjects with normal liver function showed that administration of 1-methyl-l-androstenolone in doses from 40 mg IM EOD where 3 weeks of treatment could achieve a slight increase of BSP retention, an increase of blood coagulation factors V and X, of prothrombin and progressive antithrombin III
Serum bilirubin level, activities of GOT, GPT, alkaline phosphatase, aldolase and sorbite dehydrogenase in serum, the plasma concentration of the coagulation factor VII and the thrombin time remained unchanged.
Testosterone propionate ( 40 mg IM every 2nd day) had no influence on the parameters under investigation.
The changes occurring under Primobolan treatment are considered to be symptoms of a slight disturbance of the excretory liver function; the 1-methyl substitution on the steroid nucleus seems to be responsible for this outcome however
So yes the ” needle moved” here at 140 mg a week, 100% true
Now what do we do with that data ?
1, Well we can already compare it to Testosterone
Primobolan was mildly impactful on the Liver at 140mg a week
Testosterone was not impactful here at 140mg a week
What about other Drugs ?
Boldenone ?
Remember the Boldenone study where the needle moved at 12.5mg week ?
Agreed not 100% like for like studies, they never are. But there is a big difference between BSP retention at 12.5mg a week and 140mg a week.
Takeway
Testosterone at 140mg a week = No Liver Toxicity
Primobolan at 140mg a week = some, the needle moved
Boldenone ? hell the needle moved at 12.5mg a week
Yes the overwhelming majority of Primobolan Studies are in German
and yes I go a lot further down the Rabbit Hole than anyone else I know in understanding what Drugs do what..
Maybe that interests you or not.. up to you.
