Nandrolone Decanoate at 250mg/ml — the classic long-ester Deca. 19-nor derivative of testosterone with the 19th carbon removed, providing a different metabolic pathway that does not produce DHT (it converts instead to the weaker dihydronandrolone).



Deca's reputation rests on three strengths: substantial muscle mass over longer cycles, strong support for joint and connective tissue (often noticeable within 2 to 3 weeks), and faster recovery from training. Cycles are typically 12 weeks or longer given the 15-day half-life, with doses ranging 300 to 600mg per week. Stacking with testosterone is standard.



The compound is heavily suppressive of natural testosterone, and metabolites clear slowly — up to 18 months for urinalysis purposes, which matters for tested athletes. PCT is essential. Progesterone-related side effects (nipple sensitivity, mild water retention) are possible in sensitive users and may warrant a SERM or aromatase inhibitor.
