What is MK-677?
MK-677 (Ibutamoren) is a non-peptide oral GH secretagogue that mimics ghrelin and binds to the GHS-R receptor in the pituitary, triggering sustained growth hormone and IGF-1 release. Unlike injectable peptides, MK-677 is orally bioavailable with a half-life of approximately 24 hours, allowing once-daily dosing protocols in research models. It is one of the most studied GH-stimulating compounds in the research community.
VELTRIDE supplies MK-677 10mg for Canadian research applications with ≥98% HPLC-verified purity and a Certificate of Analysis. As an oral compound shipped discreetly from West Kelowna, BC, MK-677 is popular in Canadian research programs studying GH, IGF-1, lean mass, bone density, and sleep quality endpoints.
Research Highlights
- Oral bioavailability — no reconstitution or injection required in research protocols
- 24-hour half-life enables stable GH/IGF-1 elevation with once-daily dosing
- Significantly elevates IGF-1 levels in rodent and primate models
- Studied for lean muscle mass accretion and anti-catabolic effects
- Research shows improved slow-wave (deep) sleep quality
- Bone mineral density studies show positive outcomes in aged subjects
- Appetite stimulation effect documented — relevant for wasting disease research
MK-677 vs Injectable GHRPs
MK-677 offers oral convenience with sustained GH/IGF-1 elevation compared to short-acting injectable GHRPs like Ipamorelin or GHRP-2. It can be combined with CJC-1295 for layered GH stimulation research.
