GHK-Cu 50MG

Research Peptide – Laboratory Grade

GHK-Cu is a synthetic tripeptide complex supplied for in vitro laboratory research applications.

Not intended for human or animal use, clinical use, or veterinary applications. Not for human dosing, ingestion, injection, or administration. Not intended to diagnose, treat, cure, or prevent any disease.

GHK-Cu is a copper-binding tripeptide supplied as a high-purity lyophilized powder for laboratory research and analytical applications.

Oneday Compounds 7-Point Analytical Verification

Each batch undergoes independent third-party analytical testing in the United States by a laboratory accredited to ISO/IEC 17025:2017 standards for testing competence and quality systems.

Every lot is evaluated through a structured multi-point verification protocol including:

• Identity Confirmation — Verified via compound-specific chromatographic fingerprinting (HPLC) confirming expected retention time and peak profile against reference standards
• Purity Analysis (≥99% by HPLC) — High-performance liquid chromatography profiling
• Sterility Screening — Independent sterility testing performed on multiple vials per lot (USP <71>) to confirm absence of microbial growth
• Endotoxin Assessment — Endotoxin testing (LAL) performed on multiple vials per lot to detect bacterial endotoxins beyond sterility testing alone
• Heavy Metal Analysis — Testing for trace elemental contaminants
• Conformity Verification — Confirmation of consistency in purity & content across multiple vials per lot, ensuring uniformity and reproducibility throughout each lot
• Fill Weight Confirmation — Net content verification for lot consistency

Multiple vials (8) are tested per lot across key assays to ensure results represent the entire lot, not a single sample.

Trace metals can be present at extremely low background levels during chemical synthesis. Independent ICP-MS screening verifies that any detected trace levels that remain on our COAs are well within established international pharmaceutical safety thresholds relative to the quantity of material contained in each vial.

Lot-specific Certificates of Analysis (COAs) are available here for full transparency and documentation.

This structured multi-point verification protocol supports analytical consistency and reproducibility in laboratory research applications.
