Independent laboratory verification delivers objective, impartial data that B2B can trust. Because testing is conducted by an outside facility, results are transparent and free from internal influence.

This process ensures findings cannot be modified or selectively reported, providing accurate and reliable information about the product. We appreciate your trust in us as your research partner.

Frequently Asked Questions

Everything you need to know about peptide research

What purity level are your peptides and how is it verified?
Every research peptide we ship is ≥99% pure, verified by HPLC purity testing and mass spectrometry identity confirmation at independent, accredited analytical laboratories. Each lot ships with a batch-specific Certificate of Analysis documenting the exact purity percentage, lot number, and identity verification — never a generic sample.
What is a Certificate of Analysis (CoA) and how do I read it?
A Certificate of Analysis is the third-party lab report for your specific peptide lot. Each CoA documents HPLC purity (≥99%), mass spectrometry identity, lot number, and accredited lab attribution. Browse current public CoAs at lumenpeppers.com/coa, or open any product page to view the CoA for the lot you're buying. For paperwork on a lot you already received, email hello@lumenpeppers.com with your order number.
How fast do you ship and is cold shipping required?
Lumen Peppers orders are processed and shipped within 1–3 business days from our United States facility. Lyophilized (freeze-dried) peptides don't require cold shipping — they're stable at room temperature for transit. Tracking is emailed as soon as the label is created. Full timing details: shipping policy.
Do you ship internationally?
We currently ship within the United States only, including all 50 states. International orders are not available at this time.
What if my order arrives damaged?
Every Lumen Peppers shipment includes free damage protection on the vial and packaging in transit. If your order arrives with a broken seal, cracked vial, or compromised outer packaging, email hello@lumenpeppers.com with clear photos of the issue and your order number — we'll send a replacement at no cost. Open the claim before reconstitution: once a vial is opened we can't verify the original transit condition.
How should I store the lyophilized product?
Lyophilized (freeze-dried) peptides are stable at −20°C indefinitely and remain stable at room temperature short-term for transit. Once reconstituted with bacteriostatic water, refrigerate the solution at 2–8°C and use within 30 days. Avoid repeated freeze/thaw cycles on reconstituted material — they degrade peptide integrity over time.
Do you sell bacteriostatic water for reconstitution?
Yes — bacteriostatic water (BAC water) is available in our shop as a research supply. It's sterile water containing 0.9% benzyl alcohol, which inhibits bacterial growth and is used to reconstitute lyophilized peptides for in-vitro research. Add it to your order at /product/ba-rec-water.
Are these peptides intended for human use?
No — strictly research only. Every peptide we sell is supplied for in-vitro laboratory research only. Our products are not approved by the FDA, are not drugs or supplements, and are not intended for human consumption, veterinary use, or any clinical application. By ordering you confirm you are a qualified researcher and will use the materials in accordance with all applicable laws.
