Cytomel (T3)

What is Cytomel?
Cytomel is the brand name for liothyronine sodium, a lab-made version of the thyroid hormone T3 (triiodothyronine). Your thyroid naturally produces T4 (thyroxine), which converts to T3—the active form that controls metabolism.

How It Works

• Boosts metabolism → Helps burn more calories

• Regulates energy use → Affects how your body processes fats, carbs, and proteins

• Treats hypothyroidism → Fixes low thyroid hormone levels that cause fatigue and weight gain

Common Uses
✔ Medical: Prescribed for underactive thyroid (hypothyroidism)
✔ Metabolic Support: May aid fat loss when metabolism is slow
✔ Research: Studied for metabolic disorders

Important Considerations

• Not a magic fat burner – Works best with diet and exercise

• Can cause muscle loss – High doses may break down muscle tissue

• Requires cycling – Long-term use can disrupt natural thyroid function

• Side effects – May include sweating, rapid heartbeat, or anxiety if overdosed

Safety Tips

• Always consult a doctor before use

• Never take without medical supervision

• Avoid stacking with stimulants (like Clenbuterol or caffeine) unless guided by a professional

Natural Alternatives
For healthy metabolism support, focus on:

• Balanced nutrition (enough protein, vitamins, minerals)

• Regular exercise (cardio + strength training)

• Good sleep (7–9 hours per night)
