T3 (Cytomel) 25mcg – 50 tablets. Pharmaceutical grade liothyronine thyroid hormone with consistent dosing.
Cytomel is the original pharmaceutical brand name for Liothyronine Sodium, the synthetic form of triiodothyronine (T3). F40 Biotech’s formulation delivers 25mcg per tablet in a 50 count format; the same compound and concentration as CSD’s generic and Evolve Biolabs Liothyronine listings, with the Cytomel brand name and F40 Biotech manufacturing representing the differentiating variables.
Cytomel’s brand history is the most clinically referenced T3 formulation in endocrine literature, having been the standard pharmaceutical T3 preparation for decades. Its pharmacology remains identical to generic Liothyronine. Direct delivery of active T3 bypassing peripheral T4 to T3 conversion, faster onset and more acute metabolic effect than T4, and the same risk of pituitary feedback suppression and rebound effect when used without diagnosed thyroid deficiency.
F40 Biotech 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 Liothyronine across generic, Evolve Biolabs, and this Cytomel branded F40 Biotech presentation, giving researchers brand and manufacturer flexibility within the same compound. All orders ship discreetly across Canada in plain, unmarked packaging with no identifying information on the exterior.
Liothyronine is a fast acting thyroid hormone medication that should only be used to treat a diagnosed thyroid condition under medical supervision with regular blood testing. Unsupervised use for weight loss carries real risks including cardiac strain, muscle loss, and suppression of natural thyroid function, and is not a safe or sustainable approach to weight management.
Store in a cool, dry place away from direct light and heat.
