Also known as: CAG peptide, Collagen-derived peptide, Gly-Hyp-Pro related peptide
CAG is not a standardized research-peptide designation. The letters are sometimes used loosely for collagen- or cartilage-related short sequences (for example the tripeptide Cys-Ala-Gly), but no single, vendor-sold research compound is reliably identified by "CAG," and no peer-reviewed pharmacology exists under that name.

Mechanism of Action
What "CAG" refers to
There is no consensus molecule behind the label "CAG." It is an ambiguous shorthand rather than a characterized research peptide, so this page does not assign it a fixed amino-acid sequence, molecular weight, mechanism, or dosing protocol - doing so would imply a precision that the evidence does not support.
If you arrived here looking for a specific compound:
- For a defined cartilage bioregulator, see Cartalax (Ala-Glu-Asp-Leu, AEDL).
- For collagen/skin support, see GHK-Cu (the copper tripeptide with the best cosmetic evidence).
- For general connective-tissue recovery, see BPC-157 and TB-500.
Research Use Only. We keep this entry deliberately empty of specifics because inventing a sequence or protocol for an undefined designation would be inaccurate.
Overview
CAG is not a standardized research-peptide designation. The letters are sometimes used loosely for collagen- or cartilage-related short sequences (for example the tripeptide Cys-Ala-Gly), but no single, vendor-sold research compound is reliably identified by "CAG," and no peer-reviewed pharmacology exists under that name. If you are looking for a defined cartilage-targeting peptide, see Cartalax (the Ala-Glu-Asp-Leu / AEDL Khavinson bioregulator).
