What is MK-677 Ibutamoren?
MK-677 (Ibutamoren) is the only orally active non-peptide GHSR-1a agonist. Activates pituitary and hypothalamic GHSR-1a → sustained 24hr GH/IGF-1 elevation from a single daily oral dose. Research: oral GH axis, GH deficiency models, GH pulse profile vs injectable GHRH/GHRP combinations. CAS 159752-10-0.
