| Composition | GHK-Cu 25 mg + TB-500 10 mg + BPC-157 10 mg + KPV 10 mg |
| Form | Lyophilized powder blend, single vial |
| Fill per vial | 1 vial (combined blend, see composition) |
| Purity | ≥99 % per component (HPLC) |
| Storage | 2 to 8 °C, refrigerated |
Klow brings together four separately produced peptides, GHK-Cu, TB-500, BPC-157, and KPV, each of which is verified by HPLC for purity and checked for identity ahead of blending. Because the vial merges four manufacturing lots, purity is documented per underlying component rather than as one figure for the finished blend. Certificates covering the relevant lots are available from support on request.
Keep the lyophilized blend refrigerated between 2 and 8 °C and away from light until it is needed. When reconstitution is required, use a suitable sterile solvent in the laboratory and work with the resulting solution promptly rather than storing it. No volume, ratio, or concentration recommendation for any specific application is included with this reagent.
This blend is supplied for research use only (RUO); it is not intended for administration to humans or animals and is not classified as a medicine, food, or cosmetic. Regulatory compliance and safe handling remain the responsibility of the receiving institution. The literature discusses the individual peptides across inflammatory signaling, actin-binding, gastric, and connective tissue models, described here without any efficacy claim.
Reach out to Eurolabs Peptides support with the lot numbers printed on the vial label to request certificates for the component peptides used in that batch of Klow. Each certificate reports the HPLC purity chromatogram and identity confirmation for its respective lot.
Every batch is analyzed by an independent laboratory via HPLC before shipment. We document purity (avg. 99.41% in 2026), mass spectrometry identity, and sterility. Production follows GMP standards in ISO-certified laboratories.
Klow combines GHK-Cu (25 mg), TB-500 (10 mg), BPC-157 (10 mg), and KPV (10 mg) in one lyophilized vial for laboratories running combined-reagent protocols.
Every component peptide is produced and analyzed to ≥99 % purity by HPLC before blending, matching the purity level used for each peptide as a standalone reagent.
The lyophilized blend should be kept refrigerated at 2 to 8 °C, protected from light, per the storage specification listed for this product.
Yes. Support can provide certificates of analysis for the individual component lots on request, each covering HPLC purity and identity data for that specific peptide batch.
