T3 for Fat Loss

T3, or triiodothyronine, is a natural thyroid hormone with vital roles in metabolism, cognition, and immunity. It can be used as a medication, such as liothyronine (Cytomel), to treat hypothyroidism or as a fat-burning aid in bodybuilding.

Exogenous T3 enhances metabolic rate, cognitive function, and immunity while promoting fat loss and improved insulin sensitivity. However, its misuse can lead to muscle loss, anxiety, increased heart rate, and other side effects.

To use T3 as a performance-enhancing drug (PED) for fat loss, start with 25mcg/day for two weeks, gradually increasing the dosage while monitoring side effects. T3 usage should be limited to around 8 weeks to prevent thyroid hormone suppression.

T3 can disrupt metabolism after use, requiring careful dietary control. Adequate hydration and electrolyte balance can help mitigate side effects. For best results, take T3 in the morning, preferably on an empty stomach, and complement its use with proper diet, exercise, and cardio.

T2 and T4, T3 precursors, can also promote fat loss with fewer side effects but are less potent than T3. T3 is manageable when used reasonably, making it a viable option for bodybuilders seeking to reduce body fat.

Remember, responsible T3 usage should focus on reaching lower body fat percentages rather than unnecessary fat loss. When used with care, T3 can be an effective fat loss tool for bodybuilders.
