Testosterone with nothing attached to it. Every other testosterone product carries an ester — a chain bolted onto the molecule to slow its release — and this one does not, so it enters circulation and clears again far faster than any esterified version of the same hormone.
Pharmacom Labs dissolves it in oil rather than suspending it in water, which is the more usual carrier for base testosterone. An oil vehicle is less prone to crystallising or blocking a needle than an aqueous suspension.
The vial holds 10 ml at 100 mg per millilitre.
