Liothyronine (T3) and PT-141 Interaction

Monitor
Mechanism-based 60% confidence

Liothyronine (T3) and PT-141 have an interaction requiring monitoring for interaction with 60% confidence. Both Liothyronine (T3) and PT-141 can raise blood pressure. Monitor BP regularly and consider adding cardiovascular support (cardarine, telmisartan, or similar). These compounds primarily affect different organ systems.

Compound Profiles

Liothyronine (T3)

Thyroid Hormone | Metabolic Optimization

Liothyronine enters target cells via monocarboxylate transporter 8 (MCT8) and other thyroid hormone transporters, then binds to nuclear thyroid hormone receptors (primarily TR-beta in metabolic tissues and TR-alpha in cardiac tissue). The T3-receptor complex forms heterodimers with retinoid X receptors (RXR) and binds to thyroid hormone response elements (TREs) on DNA, directly modulating gene transcription.

Half-life: ~1 day Typical dose: 25-75 mcg/day (replacement) metabolic, weight loss

PT-141

Melanocortin Receptor Agonist | Sexual Dysfunction Treatment

Selectively activates melanocortin receptors (MC3R/MC4R) in the central nervous system, triggering sexual arousal pathways independent of peripheral vascular mechanisms. Works within 45 minutes with effects lasting 6-12 hours.

Half-life: ~2.7 hours Typical dose: Women: 1.75mg (FDA-approved); Men: 1-2mg; Start 0.5mg test dose for tolerance sexual health
