Same formula as the ampoule presentation, different container. Alpha Pharma's testosterone propionate is offered here as a single 10 ml multidose vial at 100 mg/ml, closed with a rubber stopper under an aluminium crimp cap and drawn from repeatedly instead of snapped open once.
In practice that means fewer glass necks to break and one item to store rather than ten, against the need to wipe the stopper before each withdrawal. The hormone inside is unchanged: a short-ester testosterone, quick to release and correspondingly short-lived once it has been.
