Nandrolone laurate (Laurabolin) is a very long-ester veterinary form of nandrolone used in horses, dogs and cattle to improve appetite, condition and recovery. Its slow-release laurate ester gives prolonged nandrolone exposure from infrequent injections, and it has been diverted to human PED use.

01 Overview

Laurabolin is an injectable oil of nandrolone laurate developed for veterinary use, valued for supporting body condition, appetite and recovery in debilitated animals. The 12-carbon laurate ester is one of the longest attached to nandrolone, extending action over several weeks per injection.

Because it releases the same active nandrolone as Deca-Durabolin, diversion to humans yields the familiar 19-nortestosterone profile: solid mass and joint-comfort effects offset by strong, prolonged suppression and progestogenic risk. This entry covers the veterinary laurate ester specifically; users face the same nandrolone side-effects plus veterinary sourcing and sterility risks.

02 Mechanism

Nandrolone is a moderately anabolic 19-nortestosterone androgen-receptor agonist with progestogenic activity and low aromatisation; the laurate ester provides very slow, sustained release.
