Methyltestosterone is a very old steroid used way back, usually preworkout. It was not known to be good for strength or hypertrophy.
I bought some off Duchaine in the Mid-80s.
M1T is not Methyltest.
And Superdrol is methyl-drostolone, a powerful oral steroid which is essentially methylzed Masterone. But as known, once you Methylze a compound it changes its actions, including the 17-aa being hepatoxic.
