Each order includes your selected Janoshik-verified research peptides in factory-sealed vials with tamper-evident caps and batch verification labels.

All Vantix Bio peptides are >99% purity, verified through comprehensive Janoshik testing:

• HPLC for chromatographic purity analysis
• LC-MS for molecular identity confirmation
• LAL Assay for endotoxin testing (<5 EU/mg standard)

All testing is conducted by Janoshik Analytical, the industry-leading independent laboratory for peptide verification.

Yes. Every batch is tested by Janoshik Analytical before being made available for purchase.

What's included in our COAs:

• Batch-specific testing: Each production batch is tested independently (not just one sample per product)
• HPLC purity: Chromatographic purity percentage
• Peptide content: Actual peptide mass as % of total powder weight
• LC-MS identity: Molecular weight confirmation
• Endotoxin levels: LAL assay results (<5 EU/mg)

COAs are accessible for every product through our verification system. This is batch-level verification, not manufacturer claims—every vial you receive has been independently tested.

Lyophilized (powder) peptides: Store in a freezer at -20°C to -80°C for long-term stability. Keep away from light and moisture.

Reconstituted peptides: Store refrigerated at 2-8°C and use within the recommended timeframe (typically 30 days). Do not freeze reconstituted solutions.

Note: These are general research storage guidelines. Consult scientific literature for specific peptide stability data.

Verifying your Certificate of Analysis is easy:

1. Browse recent COAs: Visit the Verification Portal and click on any product to view its interactive verification report
2. Verify your specific batch: Find the Batch ID on your vial label (format: VX-XXXX-XX-XXXXXX)
3. Enter at verification portal: Go to verify.html, enter your Batch ID, and view your batch-specific test results

All COAs include HPLC purity analysis + LC-MS identity confirmation, rendered with forensic watermarking for authenticity.

Due to the nature of research materials and temperature-sensitive peptides, all sales are final. Products cannot be returned once shipped, except in cases of:

• Verified shipping damage
• Manufacturer defect
• Wrong product sent

If you experience any of these issues, please contact us within 48 hours of delivery.

If your order arrives with visible damage:

• Take photos of the damaged packaging and product
• Email us at support@vantixbio.com within 48 hours
• Include your order number and photos

We will arrange a replacement shipment or refund at no additional cost.

If you received an incorrect product, please contact us immediately at support@vantixbio.com with:

• Your order number
• Photo of the product label
• Description of the issue

We will send the correct product via expedited shipping at no charge and arrange for return of the incorrect item.

We offer one permanent discount instead of rotating promotional codes:

FOUNDER — 10% off all orders (stackable with 5% Zelle discount)

• Permanent: Works forever, no expiration
• Stackable: Combine with Zelle payment for 15% total savings
• No minimum: Applies to orders of any size

Why only one code? We'd rather invest in batch-level Janoshik testing than run promotional games. Fair pricing, every day, for every researcher.

Research Kits: We also offer pre-configured kits (Tissue Repair, GH Axis, Next-Gen, Mito, Multi-System) with built-in savings for complementary compound combinations.
