Masteron

[mikey24]

Is Masteron just injectable Proviron, or just very similar?? I can't seem to find a definitive answer.

They are comparable but not similar

And they are certainly not the same thing...

Its like comparing anadrol and tbol

[jasc]

Masteron = Drostanolone propionate

Proviron = Mesterlone

[AlinSR]

I didn't even know they were similar.

Mast is 3-methyl DHT (methylated at the 3 position to resist enzymatic deactivation in skeletal muscle).
Proviron is 1-methyl DHT (which allows for some oral bioavailability while making it milder than actual DHT).
