Overview
Shorter-acting nandrolone ester. Preferred by some users for faster clearance and easier side effect management compared to decanoate. Same parent compound as Deca-Durabolin but clears the system faster, allowing quicker recovery if side effects emerge. Requires more frequent injections (EOD or 3x/week). Harm reduction: Same monitoring as nandrolone decanoate — hematocrit, prolactin, progesterone. Faster clearance means PCT can begin sooner after discontinuation.
Mechanism of Action
19-nortestosterone derivative. Same mechanism as nandrolone decanoate but shorter ester produces faster onset and shorter duration of action.
