Frequently asked questions
What is a secretagogue?
A compound that prompts the body's own growth hormone release rather than supplying growth hormone directly. Ipamorelin and MK-677 act at the ghrelin receptor; sermorelin and CJC-1295 act at GHRH.
Is MK-677 a peptide?
No. It is a non-peptide small molecule, which is why it is orally active where the peptide secretagogues must be injected.
How is it stored?
Lyophilised material at 2 to 8 degrees Celsius. Once reconstituted, refrigerate and never freeze.
