Manufacturer’s claim vendor marketing

For a proprietary cosmetic ingredient the manufacturer is the originator — there is no upstream to defer to, and this is often the only description that exists. It is reproduced as an attributed claim, with the label its source gave it. It is not graded and it is not evidence — the graded studies are under Literature.

Vendor claims quoted from fetched page: "specifically designed to condition and strengthen eyelashes and eyebrows"; "promote the appearance of longer, thicker, and healthier-looking lashes and brows". SpecialChem page contains no clinical study data (no n=, no duration).

Manufacturer: Flychem / GfN-Selco / Shenzhen Winkey Technology (per SpecialChem); no original branded eyelash active (e.g. Symrise SymPeptide) confirmed on fetched pages
Sold as: MyriLash (Flychem); SpecPed MP 17P (GfN-Selco); WKPep Pro-Lash (Shenzhen Winkey Technology)
Manufacturer’s recommended use: Vendor claim: "0.001-0.1%"

Identity

Space-filling 3D model of Myristoyl Pentapeptide-17, carbon grey, nitrogen blue, oxygen red — Built from the SMILES on this record — the atoms, bonds and stereochemistry are exact. The shape is **one computed low-energy pose**, not a measured structure: a flexible peptide in solution has no single conformation. The skeletal formula below claims connectivity and nothing more, which is what we actually know.
