MK-677 and PT-141 Interaction

Monitor
Mechanism-based 51% confidence

MK-677 and PT-141 have an interaction requiring monitoring for interaction with 51% confidence. Both MK-677 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

MK-677

Ghrelin Receptor Agonist | Oral Growth Hormone Secretagogue

Selectively binds GHS-R1a receptors in hypothalamus and pituitary, triggering pulsatile growth hormone release while maintaining natural circadian patterns..

Half-life: ~24 hours Typical dose: Start 12.5mg daily, increase to 25mg based on tolerance growth hormone, weight loss, sleep

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
