High-Purity Research Peptides for Laboratories
Buy Vial supplies researchers, analytical laboratories, and academic institutions across Europe with rigorously tested peptides for in-vitro studies.
HPLC & Mass Spectrometry Verified
Every batch is analysed by independent third-party laboratories using high-performance liquid chromatography (HPLC) and mass spectrometry (MS). Batch-specific Certificates of Analysis (COAs) are available for download so you can verify identity, purity, and molecular weight before use.
Lyophilized & Stable
Products are supplied as lyophilized powders in sealed, contaminant-resistant vials. Stored at -20°C in a dry, light-protected environment, they remain suitable for long-term research programmes and repeated analytical work.
EU Shipping & Discreet Packaging
We ship from within Europe with tracked delivery. Orders are packed discreetly and handled according to cold-chain requirements where applicable, so products arrive in stable condition.
Research Use Only
All products are sold strictly for laboratory research and in-vitro use. They are not intended for human consumption, veterinary use, or any diagnostic, therapeutic, or clinical application.
Why Choose Buy Vial?
Finding a reliable peptide supplier for research can be difficult. We focus on three things: consistent purity, transparent documentation, and researcher-friendly service. Each product is manufactured under controlled conditions, tested by independent laboratories, and shipped with a batch-specific COA. You can trace what you receive and use it confidently in your research workflow.
Our catalogue is designed for laboratories that need dependable peptides for receptor binding studies, cell-culture assays, stability testing, and method development. We do not make health or performance claims — we provide well-characterised materials for scientific use.
Manufacturing Standards
Peptides are synthesised by solid-phase peptide synthesis (SPPS), purified to high purity, and lyophilised to remove residual solvents. Each vial is labelled with batch information and stored under controlled conditions until shipment.
How Purity Is Verified
Purity is quantified by HPLC against calibrated standards. Identity is confirmed by mass spectrometry. Additional data such as molecular weight, sequence, and appearance are recorded in the COA, giving you the documentation needed for reproducible research.
Storage Recommendations
Proper storage is essential for maintaining peptide integrity. Lyophilised powders should be kept at -20°C in a sealed container away from light and moisture. Reconstituted solutions should be prepared with sterile, bacteriostatic or distilled water according to your protocol and used within the stability window established by your laboratory.

Frequently Asked Questions
What are research peptides?
Research peptides are short chains of amino acids used in laboratory studies to investigate biological mechanisms, receptor interactions, and analytical methods. They are not approved for human or animal use.
Do you provide COAs?
Yes. Every product page includes a link to the batch-specific Certificate of Analysis. You can also browse all COAs by product name.
Who can order from Buy Vial?
We sell to qualified researchers, laboratories, and academic institutions. Customers must confirm that products are purchased for research purposes only and that they are at least 21 years of age.
Where do you ship?
We ship throughout the European Union and selected European non-EU countries. All shipments are tracked. SEPA bank transfer and Bitcoin payments are accepted.
