T3-Cytomel 25 – Product Overview
T3-Cytomel 25 (Liothyronine Sodium) is a synthetic equivalent of triiodothyronine (T3), one of the body’s primary thyroid hormones responsible for metabolic regulation. Provided in a bottle of 50 tablets at a potency of 25mcg each, Cytomel is commonly used in research involving metabolic function, thyroid hormone pathways, and energy expenditure.
Scientific Background
The thyroid gland naturally produces T4 (thyroxine), which is converted into the more metabolically active T3 in peripheral tissues, primarily the liver. T3 influences basal metabolic rate and plays a significant role in the metabolism of macronutrients. Synthetic Liothyronine is used in research to study metabolic acceleration, thyroid signaling, and hormonal interplay with energy balance.
Key Research-Based Characteristics
- Metabolic Regulation: T3 is a key hormone involved in controlling cellular metabolic rate and oxygen consumption.
- Fat Utilization Research: Frequently examined for its effect on energy expenditure and fat oxidation pathways.
- Thyroid Function Modeling: Used in studies exploring hypo- and hyperthyroid states and their physiological consequences.
- Crossover Pathway Analysis: T3 affects carbohydrate and lipid metabolism, making it relevant in multi-system metabolic studies.
- Performance & Physique Research: Often researched for its role in body composition, resting metabolic rate, and thermogenic signaling.
Product Composition
- Quantity: 50 tablets
- Strength: 25mcg Liothyronine Sodium per tablet
- Compound Type: Synthetic thyroid hormone (T3 analog)
- Form: Oral tablet
Research Applications
- Thyroid hormone metabolism and endocrine regulation studies
- Basal metabolic rate and energy-expenditure modeling
- Macronutrient metabolism (proteins, fats, carbohydrates)
- Body composition and thermogenic pathway research
