Tax included where applicable. Shipping calculated at checkout.
MK-677 (Ibutamoren) is an orally active non-peptidic growth hormone secretagogue that mimics the action of ghrelin at the GHS receptor. It stimulates GH and IGF-1 release without affecting cortisol levels. In a 12-month clinical trial, MK-677 restored GH and IGF-1 profiles in older adults to youthful levels. MK-677 is not a SARM and does not interact with androgen receptors.

Research Overview
About this compound
What does the research say?
MK-677 is a non-peptidic agonist of the ghrelin receptor (GHS-R1a). Unlike injectable growth hormone secretagogues, it is orally bioavailable and produces sustained elevations in circulating GH and IGF-1 without significantly affecting cortisol secretion.
In a randomised, double-blind, placebo-controlled trial involving healthy older adults, 25 mg/day for 12 months restored GH and IGF-1 profiles to levels characteristic of younger adults without significant adverse effects. Additional clinical data has explored its effects on body composition, bone mineral density, and sleep architecture. MK-677 significantly increased REM sleep duration and sleep quality in published clinical studies.

Why does quality matter with MK-677?
MK-677 is widely available but quality varies enormously. Many products are underdosed or contain impurities. Without independent lab verification, purity and concentration cannot be confirmed.
At Camo Chem, every batch is tested by an independent 3rd party laboratory. We publish the full Certificate of Analysis for every batch, and you can verify the results directly with the lab. We do not self-certify. Ever.

FAQ
Frequently asked questions
MK-677 is an orally active non-peptidic growth hormone secretagogue with CAS number 159752-10-0. It acts on the ghrelin receptor (GHS-R1a) and is NOT a SARM. It does not interact with androgen receptors. It is sold exclusively as a research compound.
No. MK-677 operates through a completely different mechanism. It is a growth hormone secretagogue acting on the ghrelin receptor, not the androgen receptor. It does not have androgenic or suppressive properties.
Every batch meets a minimum of 98% purity as verified by HPLC. Testing is performed by an independent 3rd party laboratory. The CoA is available on this page.
By an independent laboratory with no commercial relationship with our company. We do not self-certify. Our CoAs are verifiable directly with the testing lab.
