Nandrolone phenylpropionate is the short-ester form of nandrolone, a 19-nortestosterone androgen. The phenylpropionate ester clears the body far faster than the decanoate most people associate with nandrolone, which is why this version is classed as short-acting and calls for a more frequent injection rhythm than long-ester equivalents.
Maxtreme supplies it as an oily injectable solution at 100 mg per millilitre, boxed as ten sealed one-millilitre ampoules. Glass ampoules are single-use: nothing is left open once a dose has been drawn, which is the practical difference between this presentation and a multi-dose vial.
