DECA-DURABOLIN vs NANDROLONE DECANOATE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nandrolone decanoate is an anabolic steroid that binds to androgen receptors, increasing protein synthesis and promoting muscle growth. It also stimulates erythropoietin production, increasing red blood cell mass.
Nandrolone decanoate is an anabolic-androgenic steroid (AAS) that binds to androgen receptors (AR). Upon binding, it activates AR-mediated gene transcription, leading to increased protein synthesis, muscle growth, and bone density. It also exhibits some estrogenic activity via partial aromatization and progestogenic effects. It stimulates erythropoietin production in kidneys, increasing red blood cell mass.
Intramuscular injection of 100-200 mg every 1-3 weeks for anabolic effects; for replacement therapy, 50-100 mg every 2-4 weeks.
50-200 mg intramuscularly every 2-4 weeks

Clinical Note

Terminal half-life of nandrolone decanoate is 4.3 hours for the decanoate ester, but the active metabolite nandrolone has a prolonged half-life of 6-7 days due to slow release from intramuscular depot and enterohepatic recirculation; clinical effects persist for 3-4 weeks.
Terminal elimination half-life: approximately 6-7 days (range 4-14 days) after intramuscular injection; this long half-life supports every 2-4 week dosing intervals.
Primarily renal (90% as metabolites, 5% unchanged); fecal elimination accounts for <5%.
Renal: ~90% as metabolites (glucuronide and sulfate conjugates of 19-nortestosterone and its metabolites); fecal: ~6%; due to extensive hepatic metabolism, unchanged drug is not excreted in significant amounts.
