MK-677 Side Effects vs Ipamorelin Safety
MK-677 is a non-selective GHS-R1A agonist that causes elevated cortisol (muscle wasting, metabolic problems) and elevated prolactin (gynecomastia, sexual dysfunction, lactation). Dr. Bachmeyer positions Ipamorelin as the superior choice due to its selectivity, producing GH release without collateral hormonal disruption.
