Verified batches carry manufacturer-issued HPLC purity confirmation and full lot traceability, published as a Manufacturing COA on the product page. No shortcuts. Every batch we document is backed by manufacturer testing with a Certificate of Analysis on file.

Three-Stage Verification Protocol
Before any batch receives a BioReceptor Labs lot number, it must pass all three stages of our manufacturer testing protocol. If any stage fails, the batch is rejected — regardless of supplier, cost, or demand.
HPLC Purity Analysis
High-Performance Liquid Chromatography confirms compound purity at ≥99%. Every batch must meet this minimum threshold or it is rejected from our inventory.
≥99% REQUIRED
Identity Verification
Mass spectrometry verifies molecular weight and sequence identity against reference standards as part of manufacturer-issued testing. Confirms you receive exactly what is documented.
IDENTITY VERIFIED
Batch Traceability Screening
Manufacturer batch verification ensures each batch meets quality thresholds for laboratory use, with full lot traceability documented on every COA.
SAFETY SCREENED
Certificate of Analysis (COA)
Every order ships with a downloadable Certificate of Analysis reflecting manufacturer-issued testing on the batch. A manufacturer COA is on file for every batch we document.
Each COA documents purity percentage and chromatographic profile from HPLC analysis, molecular weight confirmation, test date, and batch-specific lot numbers for full traceability.
Research Integrity Score — Batch Criteria
Every batch is evaluated against these criteria before release. All items must pass.

Storage & Handling
All lyophilized peptide compounds are stored at recommended temperatures prior to shipment. Products ship in professional packaging with appropriate thermal protection. Upon receipt, researchers should store products according to the specifications on each product page and COA — typically at -20°C for long-term storage or 2–8°C for short-term use.
Batch Release Protocol
No batch is released for sale until all documentation has been reviewed and accepted. This means the manufacturer COA is on file, HPLC purity meets the ≥99% threshold, manufacturer-verified identity matches the reference standard, analytical results fall within acceptable limits, the lot number has been assigned and entered into our tracking system, and the product has been visually inspected for packaging integrity.
This protocol applies to every batch — first order or hundredth order, regardless of supplier history or demand urgency.
