Featured compounds
BPC-157
A synthetic 15–amino-acid peptide derived from a protein found in gastric juice, studied predominantly in animal models for soft-tissue and gastrointestinal healing.
CJC-1295
A synthetic analog of growth hormone-releasing hormone (GHRH) designed for a longer duration of action, studied for stimulating the body's own GH release.
Epitalon
A synthetic tetrapeptide (Ala-Glu-Asp-Gly) studied in longevity research, often in connection with the pineal peptide epithalamin and telomerase activity.
GHK-Cu
A naturally occurring copper-binding tripeptide (Gly-His-Lys) with genuine topical cosmeceutical research and a wider base of anecdotal use for skin and hair.
Ipamorelin
A selective ghrelin-receptor agonist studied as a growth hormone secretagogue — it prompts the pituitary to release the body's own growth hormone.
PT-141
A melanocortin receptor agonist that acts on the nervous system rather than the vascular system; one formulation (bremelanotide / Vyleesi) is FDA-approved for a specific indication.
