Description and Usage
T3, or Liothyronine Sodium, is a synthetic thyroid hormone that mimics the biological functions of triiodothyronine. It is highly effective at increasing mitochondrial activity, oxygen consumption, and nutrient utilization. This makes it a powerful tool for increasing the metabolic rate and enhancing fat loss during weight-cutting phases.
Because T3 is catabolic, it can potentially lead to muscle tissue loss if not used correctly. For optimal results, it is highly recommended to stack T3 with anabolic agents to preserve lean muscle mass. We advise a "start low, go slow" approach—begin with a minimal dose and gradually increase only as tolerance allows. To prevent long-term thyroid suppression, we recommend limiting cycles to 4 to 6 weeks and tapering the dosage down rather than stopping abruptly.
Usage Guidelines:
- Dosage: Performance use typically ranges from 25mcg to 75mcg daily.
- Precaution: Monitor your heart rate and blood pressure closely.
- Stacking: For best results, pair with an anabolic support to prevent muscle catabolism.
- Recovery: Use a tapering method when ending a cycle to support natural thyroid recovery.

FAQ
Is T3 the same as thyroid medication?
Yes, Liothyronine Sodium is a prescription-grade thyroid medication often used off-label in bodybuilding for its fat-loss properties.
Can T3 cause muscle loss?
Yes, without proper anabolic support, its catabolic effects can impact muscle tissue alongside fat loss.
How quickly do the effects become noticeable?
Users typically notice metabolic and fat-loss effects within a few days of starting their regimen.
Do I need to taper off T3?
Yes, tapering your dose gradually is essential to allow your thyroid function to recover smoothly.
Can women use T3?
Yes, however, due to higher sensitivity, it is recommended that women use lower doses, typically between 12.5mcg and 25mcg daily.
