The vial edition of Alpha Pharma's Trenbolin holds the identical trenbolone enanthate at 250 mg/ml, with all ten millilitres in one rubber-stoppered bottle rather than divided across ten ampoules.
Which format suits better comes down to handling. A vial is opened once and entered repeatedly; an ampoule stays sterile until its neck is snapped but cannot be closed again afterwards. The drug is unchanged — a long-chained, non-aromatising 19-nor androgen whose release stretches past a week. Alpha Pharma is one of the few manufacturers offering both presentations of one product.
