Nandrolone Deca Durabolin 300mg/mL – 10mL Vial

Nandrolone Decanoate, universally recognized by its pharmaceutical brand name Deca Durabolin, is one of the most extensively researched injectable anabolic compounds in clinical and sports science literature with a documented history spanning several decades across endocrine, hematological, and muscle wasting research. CSD’s 300mg/mL formulation delivers a higher concentration than the standard 250mg/mL Deca Durabolin presentations in our range, supplied in a 10mL multi dose vial for researchers requiring a reduced injection volume per dose while maintaining equivalent compound delivery.

The decanoate ester gives Nandrolone Decanoate a half life of approximately 15 days among the longest of any injectable anabolic compound. This extended release profile requires only weekly administration in documented research protocols to maintain stable blood concentration levels, making the 10mL vial format a practical long duration supply. The 300mg/mL concentration of this formulation is particularly relevant for researchers working with higher dose protocols, where the increased concentration per millilitre meaningfully reduces the injection volume required compared to standard 250mg/mL alternatives.

As a 19-nor steroid, Nandrolone Decanoate lacks the carbon atom at the 19th position of the testosterone structure, producing a substantially reduced aromatization rate compared to testosterone esters and a distinct interaction profile with androgen receptors. Deca Durabolin has accumulated particularly significant clinical literature in areas examining anabolic activity, connective tissue, bone density, and red blood cell production research areas where its long active window and well characterized pharmacokinetics make it a frequently selected reference compound.

Every batch of CSD’s Nandrolone Decanoate 300mg/mL is third party lab tested for concentration accuracy and purity prior to release, with COA documentation available on request. Canada Steroid Depot stocks Nandrolone Decanoate across multiple concentrations and formats including 250mg/mL vial, 250mg/mL ampoules, and this 300mg/mL vial alongside NPP in both vial and ampoule formats, allowing researchers to source complete nandrolone comparison sets from a single verified Canadian supplier. All orders ship discreetly across Canada in plain, unmarked packaging with no identifying information on the exterior.
