Cytomel (T3) 25mcg – 45 Tablets

Liothyronine Sodium, marketed under the pharmaceutical brand name Cytomel, is the synthetic form of triiodothyronine (T3). The most metabolically active thyroid hormone produced by the human body. Axon Pharma Corp’s formulation delivers 25mcg per tablet in a 45 count format, a precise low dose presentation consistent with the concentrations most commonly referenced in endocrine and metabolic research literature, where thyroid hormone dose response relationships are a critical research variable.

T3 is one of two primary thyroid hormones alongside thyroxine (T4), and the distinction between the two is fundamental to understanding thyroid hormone research. T4 is the predominant hormone produced by the thyroid gland but is largely inactive in its circulating form; it must be converted to T3 by peripheral deiodinase enzymes before exerting metabolic activity at the cellular level. Liothyronine as a synthetic T3 bypasses this conversion step entirely, delivering the active form of the hormone directly and producing a faster onset and more potent metabolic response than T4 based preparations like Synthroid. This pharmacokinetic distinction makes synthetic T3 a distinctly different research subject from T4, particularly in studies examining thyroid hormone conversion pathways, metabolic rate regulation, and direct versus indirect thyroid hormone activity.

T3’s relatively short half life of approximately 24 hours compared to T4’s 7 day half life is a meaningful research variable, requiring more frequent administration to maintain stable thyroid hormone levels but offering faster adjustability and quicker washout upon discontinuation. At 25mcg per tablet this formulation supports precise titration based research protocols where incremental dose response relationships across thyroid hormone pathways are being evaluated, with the low unit dose allowing for flexible upward or downward adjustment within a single tablet supply.
