# KLOW Peptide References — Peer-Reviewed Citations for KPV, GHK-Cu, BPC-157 and TB-500

> KLOW peptide references: full citations with DOIs and PubMed URLs for all peer-reviewed studies summarized on this site, covering KPV, GHK-Cu, BPC-157 and TB-500.

## KLOW references

All citations used across this site. Each maps to a numbered [N] inline marker in the body pages. Studies are attributed to the specific component they concern — no blend-level studies exist in this list, because none has been conducted. See also the [KLOW research](/research) page for context on each finding.

Full citation list is in the references_index below, including DOI and PubMed URL where available.
