What is DECA?
Nandrolone Decanoate (Deca-Durabolin) is a long-acting 19-nortestosterone ester and one of the most extensively studied AAS compounds. Moderate AR affinity, low aromatisation, and significant progestogenic activity. Active duration ~14–21 days. Research tool for joint/collagen biology, erythropoiesis, HPG axis suppression, and classic AAS pharmacology. Research use only.
