Same oil, different container. This is Alpha Pharma's methenolone enanthate presented as a single 10 ml multi-dose vial at 100 mg/ml rather than as sealed ampoules, so the rubber stopper is pierced repeatedly over the life of the bottle instead of the whole contents being drawn at once.
Vials hold more product per unit and leave less glass behind; ampoules stay sterile until the moment they are opened. Neither format is better in the abstract, it is a handling preference. What is inside is identical either way - a long-estered, non-aromatising derivative of dihydrotestosterone.
