BPC 157 10mg+GHK-CU 50mg+TB500 10mg+KPV 10mg

Compound Overview

KL80 is documented as a Nexus-only blend SKU. Its identity is defined by four listed peptide components and their stated component amounts: BPC-157 10mg, GHK-Cu 50mg, TB-500 10mg, and KPV 10mg. The product is classified as a multi-peptide blend rather than a single isolated chemical entity.

The structural description provided for this SKU is: blend of BPC-157, GHK-Cu, TB-500, and KPV; no single molecular formula or molecular weight applies. That distinction matters for receiving logs, internal sample tracking, research inventory systems, and any downstream documentation that separates component-level chemistry from blend-level catalog identity.

For laboratories evaluating this material, the appropriate interpretation is component-level. BPC-157 is listed in the source data as the pentadecapeptide component, GHK-Cu as the copper tripeptide component, TB-500 as the thymosin beta-4 component, and KPV as the tripeptide component. No additional mechanistic claims, efficacy claims, biological outcomes, or experimental conclusions are provided for this blend in the source record.

Research Background & Published Literature

The supplied research background for KL80 states that blend identity depends on component amount, purity, and COA data for each component, and that one CAS number, molecular formula, or molecular weight should not be assigned to the blend. No blend-specific citations are included in the provided research data, and no external peer-reviewed literature entries are supplied for this SKU.

Accordingly, this description does not infer blend-specific research outcomes from the names of the individual components. Researchers needing a literature review should treat BPC-157, GHK-Cu, TB-500, and KPV as separate component records and verify any published references through their own laboratory review process. Any discussion of mechanisms, assay models, or biological pathways should be supported by component-specific source material and should remain separate from unsupported claims about the four-component blend.

The source record identifies the raw Nexus catalog as the available source entry for this item. That catalog record supports the SKU, research size, category, component list, classification, physical form, intended use, and storage guidance. It does not support therapeutic activity, dosing, human use, veterinary use, disease treatment, diagnosis, disease prevention, or product performance claims in any biological system.

Storage, Handling & Stability Guidelines

Store lyophilized KL80 material at -20°C, desiccated, and protected from light. The source storage guidance further states that after reconstitution, material should be aliquoted and repeated freeze-thaw cycles should be avoided.

• Maintain the lyophilized material under the documented -20°C storage condition until it is needed for a validated laboratory workflow.
• Protect the material from moisture and light during storage and handling.
• After reconstitution, aliquot according to laboratory SOPs to reduce repeated freeze-thaw exposure.
• Use appropriate laboratory PPE and follow institutional chemical handling procedures for research reagents.
• Record product name, SKU, component amounts, reconstitution details, operator initials, and handling dates in internal logs where applicable.

The source record does not specify a post-reconstitution storage temperature, validated beyond-use interval, reconstitution diluent, concentration, assay-specific preparation protocol, or stability study. Those details should not be inferred from this product page.

Lab Verification

No exact COA data is provided for this Nexus-only blend in the source record. The available COA object contains no normalized purity, identity, batch, retention-time, mass, or component verification attributes. For that reason, this page does not list a purity percentage, batch number, test date, chromatographic retention time, or Mass Spectrometry result.

Nexus references lab verification records through the Lab Verified archive. Where current batch documentation is available, HPLC verification may be used in general terms to review chromatographic purity, and MS verification may be used in general terms to support molecular identity review. For KL80, any exact verification values should be taken only from the current batch COA or verified laboratory record, not inferred from the blend name or from component expectations.
