TB500 GHK-Cu Peptide Stack

Product Overview

The TB500 GHK-Cu Peptide Stack, available to order online from Direct Anti Peptide, represents one of the most sought-after dual-peptide research combinations in modern peptide science. Combining the well-documented regenerative research profile of TB500 (a synthetic fragment of Thymosin Beta-4) with the collagen-stimulating and cytoprotective research characteristics of GHK-Cu (Copper Tripeptide-1), this stack provides laboratories and research institutions with a high-purity, analytically verified tool for advanced in vitro experimentation. Both peptides are supplied at ≥98% purity, lyophilized, and quality-controlled to meet rigorous scientific standards.

Peptide Structure & Amino Acid Sequence

TB500 is a synthetic analogue of the naturally occurring Thymosin Beta-4 protein, comprising the core actin-binding domain sequence Ac-LKKTETQ and its extended variants. Its primary structural feature is an actin-sequestering motif that has made it a subject of extensive tissue and cellular repair research. GHK-Cu, formally known as Copper Tripeptide-1, is a naturally occurring tripeptide with the amino acid sequence Gly-His-Lys complexed with a copper(II) ion. This copper-binding tripeptide has been widely studied for its roles in fibroblast stimulation, extracellular matrix remodeling, and antioxidant activity in laboratory settings. Together, these two structurally distinct peptides form a complementary research stack with broad experimental utility.

Purity & Analytical Verification (HPLC & MS)

Every batch of the TB500 GHK-Cu Peptide Stack sold through Direct Anti Peptide undergoes comprehensive analytical verification. High-Performance Liquid Chromatography (HPLC) is employed to confirm purity at ≥98% for each individual peptide component, while Mass Spectrometry (MS) validates the precise molecular weight and structural integrity of both TB500 and GHK-Cu. These dual verification methods ensure that researchers receive consistent, reliable material suitable for reproducible experimental outcomes. Certificates of Analysis (CoA) are available upon request and reflect lot-specific analytical data.

Quality Control & Lyophilization Integrity

Both peptides within this stack are produced under strict quality control protocols and lyophilized using pharmaceutical-grade freeze-drying processes. Lyophilization removes residual moisture to below critical thresholds, preserving peptide structure and extending shelf stability during transit and storage. Each vial is sealed under inert conditions to prevent oxidative degradation, particularly important for the copper-chelated GHK-Cu component. Batch-to-batch consistency is maintained through standardized synthesis and QC workflows, providing researchers with dependable material across multiple experimental cycles.

Safety, Handling & Laboratory Precautions

This product is intended exclusively for trained laboratory professionals operating within a controlled research environment. Standard laboratory personal protective equipment (PPE) — including nitrile gloves, lab coat, and safety eyewear — should be worn at all times when handling lyophilized peptide material. Avoid inhalation of powder and contact with skin or mucous membranes. GHK-Cu contains a copper ion complex; appropriate chemical handling procedures for metal-chelated peptides should be observed. All waste material must be disposed of in accordance with applicable institutional and local regulatory guidelines. This product is not intended for use in humans, animals, or any consumptive application.

Reconstitution, Packaging & Storage

The TB500 GHK-Cu Peptide Stack is packaged with each peptide supplied in its own individually sealed vial to preserve integrity and prevent cross-contamination. Reconstitution should be performed using appropriate laboratory-grade solvents and buffers as determined by the principal investigator’s experimental protocol. Lyophilized vials should be stored at -20°C for long-term stability. Once reconstituted, solutions should be stored at 4°C and used within a timeframe consistent with established laboratory best practices for peptide solutions. Do not expose to repeated freeze-thaw cycles. Keep away from direct light and humidity.

Intended Research Use & Market Positioning

The TB500 GHK-Cu Peptide Stack is positioned as a premium dual-peptide research tool for scientists investigating cellular regeneration, extracellular matrix dynamics, antioxidant peptide activity, and tissue-level biological processes in vitro. TB500 has been the subject of numerous published studies examining actin dynamics and cellular motility, while GHK-Cu continues to attract significant research interest in dermatological science, wound biology, and gene expression modulation. This stack offers a cost-effective and convenient way to explore the combined or comparative effects of both peptides within a single research purchase.
