What does the research say?
MK-677 (ibutamoren) is a non-peptidic, orally active agonist of the ghrelin receptor (GHS-R1a). In the published literature the compound is described as mimicking the action of ghrelin at its receptor and producing sustained elevation of growth hormone (GH) and IGF-1 signalling in the models studied, without the cortisol elevation reported for some other secretagogues. It is not a SARM and does not interact with androgen receptors.
The research base includes long-duration randomised, placebo-controlled studies on GH and IGF-1 profiles, work on sleep architecture (REM sleep duration), and preclinical work on bone and body composition. The peer-reviewed references are listed below and every reference can be opened and checked.
Independent lab test: batch MK677-S2-2026
The current MK-677 batch (MK677-S2-2026, 25 mg/ml solution) was analysed by an independent laboratory in July 2026 with identity confirmed and purity certified above the 96% HPLC acceptance threshold. The full report, sample photos and the link to verify the certificate in the laboratory database can be reached through our lab testing page. A certificate that can be checked directly in the lab database cannot be edited or fabricated, unlike a self-issued PDF. How to read an HPLC certificate is explained on the lab testing page.
Why does quality matter with MK-677?
MK-677 is one of the most commonly underdosed compounds on the market. Many suppliers sell products with no third-party verification, relying on self-issued "Certificates of Analysis" that anyone can create in a word processor.
At Camo Chem, every batch is tested by an independent 3rd party laboratory. The full Certificate of Analysis is published for every batch and the results can be verified directly with the lab. Camo Chem does not self-certify. Ever.
A fair question for any supplier: who tests their products?

Items reached safely. Works wonders. Highly recommend buying from this site. Proper packaging. Prompt replies. Thank you

For the past 2 years I have been researching with MK677 from what is regarded as one, if not the best company in the UK. I found myself needing to find another supplier, I came across CAMO and the transition has been flawless, I now see CAMO as equally of the highest standard and will be a returning customer throughout 2024, 100 %. If you are in the market for "The real deal" then I can confirm you can purchase from CAMO with complete peace of mind . Keep up the great work and happy new year to all .
