Testosterone 400mg/mL is an injectable androgen formulation in MCT oil supplied in a 10mL vial. Manufactured for consistency, stability, and research applications.
Testosterone 400mg/mL is a high concentration injectable testosterone formulation delivering 400mg of testosterone per milliliter in a 10mL multi dose vial using MCT (medium chain triglyceride) oil as the carrier base. At 400mg/mL this represents one of the highest concentration testosterone formulations in CSD’s injectable range, and MCT oil’s exceptionally low viscosity is a critical carrier choice at this concentration level; heavier traditional oil carriers like cottonseed or sesame oil would present significantly increased draw and administration resistance at 400mg/mL, making MCT oil the most practical carrier for a high load testosterone formulation of this concentration.
The defining characteristic of this formulation is its concentration 400mg/mL delivers a substantially higher testosterone payload per milliliter than standard single ester formulations like CSD’s 200mg/mL and 250mg/mL testosterone variants. For research protocols requiring higher dose administration, this high concentration format allows equivalent compound delivery in a significantly reduced injection volume compared to lower concentration alternatives. This volume reduction is a meaningful practical consideration in protocols involving repeated long term administration where minimizing injection volume per dose is a priority variable.
As a testosterone based formulation, this compound aromatizes to estrogen, supports androgen receptor activity, and produces the full hormonal profile associated with exogenous testosterone administration. Researchers selecting between CSD’s standard concentration single ester testosterone formulations and this high concentration variant will find the base compound pharmacology consistent concentration and carrier representing the primary selection variables for protocol planning purposes.
Every batch of CSD’s Testosterone 400mg/mL 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 high concentration testosterone range represents some of the most specialized formulations available from a verified Canadian supplier. All orders ship discreetly across Canada in plain, unmarked packaging with no identifying information on the exterior.
Store at room temperature away from direct light and heat. Do not freeze. Intended for research purposes only.
