Same hormone and the same 250 mg per millilitre as the ampoule version of Nandrobolin, presented instead as a single 10 ml vial closed with a rubber septum.
A multi-dose vial keeps all ten millilitres behind one stopper, so it contains a bacteriostatic preservative - benzyl alcohol, as a rule - that lets it be entered repeatedly; ampoules need none. Which format suits better is a question of handling rather than of what is dissolved in the oil. Alpha Pharma print a scratch-off verification panel on the carton in both cases.
