Ipamorelin
Ipamorelin is a selective growth-hormone secretagogue studied in laboratory research for growth-hormone release and recovery. It is a research compound and is not approved by the FDA for human use.
What is Ipamorelin?
Ipamorelin is a selective growth-hormone secretagogue. Ipamorelin functions as a growth hormone secretagogue that activates IGF-1 signaling pathways, thereby promoting tissue regeneration. It stimulates the release of growth hormone, which in turn supports satellite cell repair and cellular proliferation involved in musculoskeletal healing.
It is best referenced by its chemistry (PubChem CID 9831659, molecular formula C38H49N9O5). Ipamorelin is sold and discussed for laboratory and research use only.
