Liothyronine Sodium is the synthetic form of triiodothyronine (T3), the metabolically active thyroid hormone. This generic formulation delivers 25mcg per tablet in a 100 count format; the highest tablet count across CSD’s Liothyronine listings, sitting above the 50 tablet generic and Evolve Biolabs presentations, suited to extended protocols or researchers maintaining standing supply without frequent restocking.
The same fundamental risk profile applies regardless of pack size. T3’s direct activity and faster onset relative to T4 mean its effects are felt more quickly and more acutely, which is part of why it’s sometimes referenced in weight loss contexts for its immediately noticeable metabolic impact. But artificially elevating thyroid hormone without diagnosed need triggers pituitary feedback suppression of the body’s own thyroid production, commonly producing a rebound effect once use stops, alongside cardiac strain and muscle protein breakdown risk if used without adequate caloric and protein intake.
Every batch of CSD’s Liothyronine is third party lab tested for concentration accuracy and purity before being made available, with COA documentation available on request. CSD stocks Liothyronine 25mcg across 50 tablet generic, 50 tablet Evolve Biolabs, and this 100 tablet generic format for complete pack size flexibility. 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.
