NANDROLONE DECANOATE vs NANDROLONE PHENPROPIONATE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Nandrolone phenpropionate is an anabolic steroid that binds to androgen receptors, activating gene expression leading to increased protein synthesis, nitrogen retention, and muscle growth. It also exhibits weak androgenic activity and may inhibit glucocorticoid receptors.

Clinical Note
moderateAcarbose + Nandrolone decanoate
"Acarbose may increase the hypoglycemic activities of Nandrolone decanoate."
Clinical Note
moderateSunitinib + Nandrolone decanoate
"Sunitinib may increase the hypoglycemic activities of Nandrolone decanoate."
Clinical Note
moderatePrednisolone + Nandrolone decanoate
"Prednisolone may increase the fluid retaining activities of Nandrolone decanoate."
Clinical Note
moderateDexamethasone + Nandrolone decanoate
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.
Terminal elimination half-life approximately 8-10 hours, but active metabolite 19-nortestosterone has a longer half-life (~2-4 hours), necessitating frequent dosing for stable blood levels.
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.
Primarily renal (90% as metabolites, mainly glucuronide and sulfate conjugates; 6% as unchanged drug); about 4% fecal.
