HCG 25000IU is a research grade human chorionic gonadotropin formulation supplied as 5 x 5000IU vials. Manufactured for purity, stability, and controlled laboratory applications.
Human Chorionic Gonadotropin (HCG) is a glycoprotein hormone naturally produced by syncytiotrophoblast cells of the placenta during pregnancy, with a well established pharmaceutical history spanning several decades of clinical application in fertility, endocrine, and reproductive medicine research. Hudson Science’s formulation supplies 25000IU total across five individually sealed 5000IU lyophilized vials, a high volume multi unit research supply that provides significantly greater total compound availability than the F40 Biotech 15000IU prefilled pen, designed for extended research protocols or laboratory settings requiring consistent HCG availability across multiple administration timepoints from matched batch vials.
The 5 x 5000IU vial configuration is a pharmacologically practical format for HCG research. Reconstituted HCG in solution maintains stability for approximately 30 days under refrigeration. A longer window than growth hormone but still a meaningful consideration for multi week protocols where individual sealed vials reconstituted only when required preserve compound integrity more reliably than a single large volume preparation used across an extended timeline. The 5000IU per vial unit dose is consistent with the concentrations most commonly referenced in clinical HCG research literature for gonadal stimulation and HPG axis restoration protocols, providing precise per administration compound availability without excess reconstituted solution requiring extended refrigerated storage.
HCG’s pharmacological activity operates through LH receptor binding, its shared beta subunit structure with luteinizing hormone enabling direct Leydig cell testosterone stimulation in testicular tissue, bypassing the hypothalamic pituitary axis entirely. This direct gonadal LH receptor activation distinguishes HCG from SERMs like Clomiphene and Tamoxifen which stimulate endogenous LH production indirectly through HPG axis modulation, and from HMG which delivers both FSH and LH gonadotropin activity simultaneously. Within CSD’s PCT and gonadotropin research range, HCG’s pure LH mimicking gonadal stimulation profile makes it a frequently studied reference compound for isolated Leydig cell function and endogenous testosterone restoration research.
Hudson Science formulations are stocked by Canada Steroid Depot following the same rigorous third party lab verification process applied to every product in our range. Each batch is tested for concentration accuracy and purity before being made available, with COA documentation available on request. CSD stocks HCG across multiple formats: this Hudson Science 5 x 5000IU vial kit, the F40 Biotech 15000IU prefilled pen, and the iLab Pharma HMG 75IU for complete gonadotropin research coverage, alongside the full SERM range for comprehensive HPG axis restoration research sourcing from a single verified Canadian supplier. All orders ship discreetly across Canada in plain, unmarked packaging with no identifying information on the exterior.
Reconstitute individual vials with bacteriostatic water prior to use. Store lyophilized vials at 2–8°C away from direct light. Once reconstituted refrigerate and use within 30 days. Intended for research purposes only.

havent tried it yet as i dont feel my natural test has been affected by fake sustanon
