KPV and KLOW80
Two related catalog entries: the single tripeptide KPV, and KLOW80, a co-lyophilized four-compound blend. Both sit in the recovery class on Compound Reference.
This page is composition and verification context only—not a protocol and not a claim of combined biological effect.
KPV — identity
Tripeptide Lys-Pro-Val, the C-terminal fragment (11-13) of alpha-melanocyte-stimulating hormone.

KLOW80 — four-compound blend
KLOW80 is not a single peptide. It is a co-lyophilized blend, 80 mg total, with stated component masses:
| Component | Amount in blend |
|---|---|
| GHK-Cu | 50 mg |
| BPC-157 | 10 mg |
| TB-500 (thymosin beta-4) | 10 mg |
| KPV | 10 mg |
| Field | Value |

| Catalog name | KLOW80 |
| Class | Recovery |
| Form | Lyophilized powder, sealed under nitrogen |
| Nominal MW (components) | 403.9 / 1419.5 / 4963.4 / 342.4 g/mol |
| Molecular formula | Four-compound blend |

The copper complex (GHK-Cu) gives the powder a blue to blue-violet tint. Product: KLOW80.
Specifications context
For single-compound KPV, read the lot COA as usual. For KLOW80, treat the certificate and label as documentation of a defined multi-component blend—confirm the lot on Certificates of Analysis and review methods on Third-Party Testing.
