KLOW Index

A gunmetal data-console reading of the four-peptide KLOW research record — KPV, GHK-Cu, BPC-157 and TB-500 logged as four channels on one dense instrument panel, the component literature tabulated and the blend's missing combination data flagged as a null row.

Return to the findings

What did the TB-500 and beta-4 papers find?

The wound test used the whole beta-4 protein, not short TB-500. A second TB-500 paper weighs the safety of unapproved peptides.

[1] Malinda KM, et al. This paper found faster wound healing with the whole beta4 protein. J Invest Dermatol. 1999;113(3):364-368. DOI: 10.1046/j.1523-1747.1999.00708.x. PMID: 10469335. https://pubmed.ncbi.nlm.nih.gov/10469335/

[7] Mendias CL, Awan TM. This review looks at approved and unapproved peptides used for muscle or joint injuries and sport. Sports Med. 2026. DOI: 10.1007/s40279-026-02437-0. PMID: 41966639. https://pubmed.ncbi.nlm.nih.gov/41966639/

What did the BPC-157 papers ask?

[2] Staresinic M, et al. This paper found that BPC 157 helped a rat Achilles tendon heal after it was cut all the way through. Tendon cells in a lab dish grew faster too. J Orthop Res. 2003;21(6):976-983. DOI: 10.1016/s0736-0266(03)00110-4. PMID: 14554208. https://pubmed.ncbi.nlm.nih.gov/14554208/

[6] Lee E, Burgess K. This small paper checked BPC157 put into a vein in people and watched for harm. Altern Ther Health Med. 2025;31(5):20-24. PMID: 40131143. https://pubmed.ncbi.nlm.nih.gov/40131143/

[8] Sikiric P, et al. This rat paper asked whether BPC 157 protected the stomach from ulcers. World J Gastroenterol. 2004;10(7):1032-1037. DOI: 10.3748/wjg.v10.i7.1032. PMID: 15052688. https://pubmed.ncbi.nlm.nih.gov/15052688/

[14] (Author group). This rat paper asked whether BPC 157 closed an unwanted hole between two parts of the bowel. It also looked for protection from tissue harm. J Physiol Pharmacol. 2024. DOI: 10.26402/jpp.2024.1.09. PMID: 38583442. https://pubmed.ncbi.nlm.nih.gov/38583442/

[15] Lee E, Walker C, Ayadi B. This small report asked whether BPC-157 eased pain and other signs from a sore bladder. Altern Ther Health Med. 2024. PMID: 39325560. https://pubmed.ncbi.nlm.nih.gov/39325560/

None of these papers proves a KLOW result for you.

What did the KPV papers ask?

Paper [3] is by Dalmasso G, Charrier-Hisamuddin L, Nguyen HT, Yan Y, Sitaraman S, and Merlin D. It found that a bowel carrier moved KPV into cells and swelling fell. Gastroenterology. 2008;134(1):166-178. DOI: 10.1053/j.gastro.2007.10.026. PMID: 18061177. https://pubmed.ncbi.nlm.nih.gov/18061177/

[9] Kannengiesser K, Maaser C, Heidemann J, et al. This mouse paper found that KPV may ease swelling in a sore bowel. Inflamm Bowel Dis. 2008;14(3):324-331. DOI: 10.1002/ibd.20334. PMID: 18092346. https://pubmed.ncbi.nlm.nih.gov/18092346/

[10] Bettenworth D, Buyse M, Bohm M, et al. This paper found that a close cousin of KPV helped the bowel wall keep harmful matter out. Am J Pathol. 2011;179(3):1230-1242. DOI: 10.1016/j.ajpath.2011.05.013. PMID: 21741932. https://pubmed.ncbi.nlm.nih.gov/21741932/

[11] Viennois E, Ingersoll SA, Ayyadurai S, et al. This mouse paper asked whether a bowel carrier helped KPV cut the long-term swelling tied to cancer. Cell Mol Gastroenterol Hepatol. 2016;2(3):340-357. DOI: 10.1016/j.jcmgh.2016.01.006. PMID: 27458604. https://pubmed.ncbi.nlm.nih.gov/27458604/

[13] Bobyntsev II, Chernysheva OI, Dolgintsev ME, Smakhtin MY, Belykh AE. This rat paper looked for less fear and worry after GHK. Bulletin of Experimental Biology and Medicine. 2015;158(6):726-728. DOI: 10.1007/s10517-015-2847-3. PMID: 25900608. https://pubmed.ncbi.nlm.nih.gov/25900608/
