MK-677
MK-677, made simple.
MK-677 is the oral, once-daily GH secretagogue — the most clinically studied compound in its category. PepEasy gives you a clean place to understand it, track your protocol, and ask questions grounded in real research.
Educational only — not medical advice. PepEasy never recommends a dose.
MK-677, also called Ibutamoren, is an orally active, non-peptide ghrelin mimetic that raises growth hormone and IGF-1 with once-daily dosing. It is the most clinically studied compound in the GH-secretagogue category and the only one taken as a pill rather than injected. PepEasy is where you learn about MK-677 and track your protocol.
What MK-677 is
MK-677 — Ibutamoren — is a synthetic, orally bioavailable, non-peptide growth-hormone secretagogue. Its spiropiperidine structure resists gut breakdown, so unlike the injectable peptides in this category it survives oral dosing. It acts as a ghrelin mimetic, binding the same receptor as the hormone ghrelin to drive a sustained, day-long rise in GH and IGF-1. Despite living in the peptide world by association, it is a small molecule, not an amino-acid chain.
What people explore MK-677 for
- Supporting growth hormone and IGF-1 with a single daily pill
- Lean mass and body-composition goals
- Sleep support, with reported increases in REM and slow-wave sleep
- Oral convenience compared with injectable GH secretagogues
- Stacking with injectable peptides like CJC-1295 and Ipamorelin

Frequently asked
Is MK-677 a steroid or a SARM?+
Neither. MK-677 is a ghrelin mimetic and GH secretagogue. It is often grouped with SARMs in the market, but it works through a different GH and IGF-1 pathway. PepEasy helps you understand the distinction.
Is MK-677 injected or taken orally?+
Orally — that is its key distinction from the injectable peptides in this category. It is dosed once daily, often before bed, and PepEasy makes tracking a daily pill simple.
Does PepEasy recommend an MK-677 dose?+
No. PepEasy is educational and a tracker. It helps you understand MK-677 and organize your protocol; dosing decisions belong with a qualified healthcare professional.
