Read the evidence
The cited dry-eye trial studied an ophthalmic formulation. It does not establish efficacy of systemic preparations or short TB-500 fragments.
Resolve the identity
Keep the 43-residue parent distinct from N-acetylated LKKTETQ sold as TB-500. Terminal modifications and formulation also matter.
