Alpha Pharma's nandrolone line carries the Nandrobolin name, and this is the ampoule presentation - ten sealed glass units, one millilitre each, at 250 mg of nandrolone decanoate per millilitre.
An ampoule is snapped open and used in one go, which takes the question of a repeatedly pierced stopper off the table entirely. Inside is the long-ester form of 19-nortestosterone: a hormone whose conversion to oestrogen is markedly weaker than testosterone's, though its progestogenic side is the part that gives it a character of its own.
