Nandrolone Decanoate, commonly known as Deca Durabolin, is one of the most extensively researched anabolic compounds in sports science and endocrine literature. CSD’s formulation delivers 250mg/mL in a 10mL multi dose vial using cottonseed oil as the carrier base; a well established injectable medium known for its stability, low oxidation rate, and long shelf life in oil based formulations.
The decanoate ester gives Nandrolone one of the longest half lives among injectable compounds, estimated at approximately 15 days. This extended release profile means blood concentration levels remain elevated for an extended period following administration, making it well suited to research protocols requiring infrequent injection schedules and sustained compound presence. The slow release also contributes to the compound’s reputation for gradual, stable activity in research settings.
Nandrolone Decanoate is distinct from testosterone based compounds in that it is a 19 nor steroid, meaning it lacks the carbon atom at the 19th position of the testosterone structure. This structural difference produces a notably different interaction with androgen receptors and a significantly reduced rate of aromatization compared to testosterone esters, making it a frequently studied compound in research examining anabolic activity independent of estrogenic conversion.
Every batch of CSD’s Nandrolone Decanoate is third party lab tested for concentration accuracy and purity, with COA documentation available on request. Canada Steroid Depot has supplied Canadian customers with consistently verified, accurately dosed compounds for years. Deca Durabolin remains one of our most consistently reordered injectable products. All orders ship discreetly across Canada in plain, unmarked packaging.

Nandrolone Decanoate, most widely known by the brand name Deca Durabolin is a 19-nortestosterone derivative and one of the most extensively researched anabolic compounds in the literature. It demonstrates a high anabolic to androgenic ratio, strong nitrogen retention properties, and significant collagen synthesis stimulation; making it one of the most studied compounds for lean mass accretion, joint support, and connective tissue research. It was originally developed for muscle wasting, osteoporosis, and anemia research and has one of the longest clinical research histories of any injectable anabolic compound.
Nandrolone Decanoate has a half-life of approximately 6–12 days; typically administered once or twice weekly in research protocols. Once weekly administration at 250–500mg is the most common research schedule, providing stable plasma Nandrolone levels throughout the cycle. Due to its long half-life, Nandrolone Decanoate takes longer to clear from the system than shorter acting compounds. A consideration for PCT timing, which should typically begin 3 weeks after the last Nandrolone Decanoate injection rather than the 2-week window used for testosterone enanthate.
Nandrolone Decanoate aromatizes to estrogen at approximately 20% the rate of testosterone; producing modest estrogen elevation. More significantly, Nandrolone is a progestin with moderate progesterone receptor affinity and in combination with estrogen, this progestin activity can stimulate prolactin elevation. Prolactin management with Cabergoline or Pramipexole is commonly researched alongside Nandrolone containing protocols. Estrogen management with a mild aromatase inhibitor is also recommended in most research contexts.
Nandrolone Decanoate is most commonly researched alongside a testosterone base typically Testosterone Enanthate or Cypionate as the suppression of endogenous testosterone production by Nandrolone requires exogenous testosterone for hormonal maintenance. The classic bulking stack of Testosterone Enanthate + Nandrolone Decanoate is one of the most extensively researched compound combinations in the anabolic literature, studied for synergistic lean mass and strength outcomes.
Yes! This batch has been independently HPLC tested by an accredited third party laboratory confirming concentration accuracy at 250mg/mL and compound identity as Nandrolone Decanoate. A certificate of analysis is available.
