Dianabolos is Pharmacom Labs' entry in the methandienone category, supplied as 100 tablets of 10 mg. Pharmacom built much of its standing on publishing third-party assay results for its batches, and that habit is a large part of why the brand gets discussed the way it does.
Being an oral, the compound is swallowed rather than injected - no needles, but the load moves to the liver instead. It is structurally testosterone with an extra double bond and a 17-alpha methyl group, the first change reducing conversion to dihydrotestosterone and the second making the tablet route possible.
