MK-677

Q: How should MK-677 be stored?

Sealed lyophilized vials are stored cold and away from light, typically frozen for long-term storage. Once reconstituted for research, material is kept refrigerated and protected from light.

Non-peptide growth-hormone secretagogue (ibutamoren) · encapsulated research materials

MK-677 (research name ibutamoren) is a non-peptide small molecule that acts as a ghrelin-receptor (GHS-R) agonist and growth-hormone secretagogue. It is supplied in capsule form as a reference material for laboratory use.

Research context

In published literature, MK-677 is studied in the context of growth-hormone-axis and ghrelin-receptor pathway research using in-vitro and preclinical models. Glow Peptides supplies MK-677 strictly as a reference material for such in-vitro and preclinical research. It is not a therapeutic product and is not for human or veterinary use.

Handling & storage

MK-677 is supplied in capsule form as a research reference material. General laboratory handling practice for encapsulated materials of this type:

Storage: keep capsules sealed in a cool, dry place away from light and humidity; refrigeration extends shelf life.
No reconstitution: encapsulated reference materials are handled as supplied — there is no solvent or reconstitution step.
Documentation: record the lot number and its Certificate of Analysis for your records.

Quality & testing

Every lot of MK-677 we supply is independently tested at a U.S. laboratory and ships with a lot-specific Certificate of Analysis. Testing includes HPLC with UV detection for purity and mass spectrometry for identity, with our purity standard at ≥99%.

You can search any lot and view its documentation on our Quality & COA verification page, and learn what the numbers mean in how to read a Certificate of Analysis. Our published customer rating is 4.5 on Trustpilot.

MK-677 is available as an independently tested, ≥99%-purity research reference material with a per-lot Certificate of Analysis.
