Pharmacom Labs builds its injectable range around multi-dose vials, and this is the short-ester nandrolone entry: 10 ml of oil solution at 100 mg per millilitre under a crimped rubber stopper.
Phenylpropionate is the shortest ester commonly fitted to the nandrolone molecule. Where the decanoate form lingers for weeks after an injection, this one is measured in days, which places it among the short-acting injectables and means it is administered more frequently. Nandrolone itself is a 19-nor compound, structurally testosterone without the carbon at position 19.
