I have seen it mostly at around 100-150mg/ml but know it is currently being produced at 250mg/ml which seems pretty high. Have not tried it myself at that ratio.
ya I am a fane of a lot of the second generation steroids that have come out in the last few years. One of which is not m1t though. Even i have to admit this stuff is pretty damn toxic. Superdrol is avbout as much as I think anyone should push it to. After that the risks start to fare outweigh the gains.
