Liothyronine 25 - Stealth Labs

Liothyronine sodium was introduced in the 1950s under the name Cytomel® as a pharmaceutical-grade T3 hormone. Designed to replace crude animal thyroid preparations, it provided more consistent and rapid metabolic stimulation. Its short half-life made it ideal for patients needing fast relief from hypothyroidism. Later, it gained widespread off-label use in bodybuilding, where it became a favored agent for fat-loss cycles. The compound’s direct action and ability to elevate basal metabolic rate allowed athletes to manipulate body composition quickly before contests or photo shoots.
