What is it—and why does it matter?

The labeled use indicates scalp hair regrowth for a product whose active ingredients include sr-Rainbow Trout Oligopeptide-1 components. The labeled directions specify topical application (face and neck) with a measured pump amount and frequency.

This published profile is a reference in progress. Findings retain their source context; missing topics are marked below.

What is it?

A molecule, not a product name.

Identity

The intervention described as a topical recombinant epidermal growth factor (REGF) serum is explicitly labeled as oligopeptide-1 in the study aim.
