Checking out the M1T sticky at the top of this board will give you a few answers.
I personally think that sticky is in dire need of removal, as M1T was declared illegal (if memory serves me correctly around Jan of 05) and since both steriods and prohormones are in the same "banned" class, why would you mess with M1T when it is far inferior to steriods?
I'm not advocating steriods, but if you're going to purchase something illegal, why would it be M1T? Why not something "stronger"?
Anyway, read the sticky, it will give you a lot more info you may not have considered when taking M1T, such as starting slower and increasing doses, and particularly stacking it with milder prohormones to minimize sides.
