SUSTANON 250mg/mL – MCT Oil – 10mL Vial

Sustanon 250 is a multi ester testosterone blend formulated to deliver both rapid onset and sustained release of testosterone through a single administration, combining short, medium, and long acting testosterone esters in a single preparation. CSD’s formulation delivers 250mg/mL in a 10mL multi dose vial using MCT (medium chain triglyceride) oil as the carrier base; a notable departure from the traditional oil carriers historically associated with Sustanon formulations, with MCT oil’s ultra low viscosity providing meaningfully smoother administration characteristics than the heavier carriers typically used in multi ester testosterone blends.

The multi ester composition of Sustanon produces a broader and more complex release curve than any single ester testosterone formulation. Shorter esters elevate testosterone levels quickly following administration while longer esters sustain release over an extended period, producing a staggered concentration profile that distinguishes Sustanon from CSD’s single ester Testosterone Enanthate, Cypionate, and Decanoate offerings. MCT oil as a carrier complements this multi ester profile particularly well. Its low viscosity ensures smooth administration despite the complexity of the blended ester suspension, and its clean composition supports stable uniform dispersion of multiple ester compounds within a single solution.

CSD stocks Sustanon 250 across three formats,  this MCT oil vial, a grapeseed oil vial variant, and a 10 x 1mL ampoule presentation with the base compound, concentration, and ester blend remaining identical across all three. Carrier and packaging format represent the sole differentiating variables between listings, giving researchers the flexibility to select based on administration preference and protocol length without switching compounds or manufacturers.

Every batch of CSD’s Sustanon 250 MCT oil formulation is third party lab tested for concentration accuracy and purity prior to release, with COA documentation available on request. Canada Steroid Depot has supplied Canadian customers with consistently verified, accurately dosed compounds for years, and our Sustanon range across all formats remains among our most reordered testosterone products. All orders ship discreetly across Canada in plain, unmarked packaging with no identifying information on the exterior.
