Pages on this site summarize findings from published, peer-reviewed human trials of MK-677, for example, changes in IGF-1, sleep architecture, and body composition recorded by independent researchers. Every figure is cited to its source publication on the Science page.

These summaries describe what third-party researchers reported about the compound under trial conditions. They are not claims about what any Primeletic product will do, and they are not a promise of any outcome. The cited studies were conducted on the compound independently of Primeletic and did not use Primeletic products.

Certificates of analysis published on our Lab Results page are issued by an independent analytical laboratory and describe the identity and purity of the specific batch sample tested. A certificate is a statement about chemical composition, it is not an endorsement of any use, and it does not alter the research-use terms above.
