General Questions
What is Kynbio?
Kynbio Bio LLC is a wholesale distributor of research-grade biochemical compounds, including synthetic peptides, bioregulatory peptides, amino acids, enzyme substrates, and analytical reference standards. We supply researchers, academic institutions, and independent laboratories with rigorously sourced materials for in vitro and preclinical research.
Who can purchase from Kynbio?
Our products are sold exclusively for research purposes to qualified researchers, academic institutions, biotechnology companies, and independent laboratories. By placing an order, you confirm that you are purchasing for legitimate scientific research and that you understand all products are for in vitro or preclinical use only — not for human or veterinary consumption.
Are your products for human use?
No. All products sold by Kynbio are strictly for research use only and are not intended for human or veterinary consumption, therapeutic use, or clinical application. They have not been evaluated or approved by the FDA for any such use.
Products & Quality
What purity levels do your products meet?
Our peptides and amino acids are supplied at ≥98% purity (HPLC) as a standard. Enzyme substrates and reference standards meet their own specifications, which are detailed on each product page. Every lot is characterized by reverse-phase HPLC and ESI mass spectrometry before release.
Do you provide Certificates of Analysis (CoA)?
Yes. A lot-specific Certificate of Analysis is available for every product. CoAs include HPLC chromatograms, mass spectrometry confirmation, and purity values. They are available on the Analytical Verification (COA) page or by request at kynbio.co@gmail.com.
How are your products tested?
All products undergo third-party analytical verification including HPLC purity analysis and ESI-MS molecular weight confirmation. Reference standards additionally undergo NMR characterization and Karl Fischer water content analysis. We do not release any lot without passing our internal QC review.
Do you offer custom synthesis?
Yes. We offer custom peptide synthesis and custom enzyme substrate synthesis. Visit our Custom Synthesis catalog page or contact us at kynbio.co@gmail.com with your sequence requirements, desired purity, and quantity.
Ordering & Payment
What payment methods do you accept?
We currently accept cryptocurrency payments (Bitcoin, Ethereum, USDC) via Coinbase Commerce, and bank transfer (wire/ACH) for larger institutional orders. Additional payment methods will be added as we grow. Contact us if you have specific payment requirements.
Can I place a bulk or institutional order?
Yes. We welcome bulk orders and institutional purchase orders. Contact us at kynbio.co@gmail.com with your requirements and we will provide a quote with volume pricing.
Do you offer a researcher verification process?
Yes. We may require verification for certain products or order sizes. You can submit your research credentials through our Researcher Verification Form.
Shipping & Handling
Where do you ship?
We ship domestically within the United States and internationally. Free shipping is available on orders over $200. See our Shipping & Logistics page for full details on carriers, timelines, and cold-chain handling.
How are peptides shipped to preserve integrity?
Lyophilized peptides are stable at ambient temperature for short transit periods. For longer transit or heat-sensitive compounds, we use insulated packaging with cold packs. All products are shipped in sealed, desiccated containers with the lot number clearly labeled.
How do I track my order?
Once your order ships, you will receive a tracking number by email. You can also track your order anytime on our Order Tracking page using your order number and email address.
Returns & Refunds
What is your return policy?
Due to the nature of research biochemicals, we do not accept returns on opened products. If your order arrives damaged, mislabeled, or does not match your CoA specifications, contact us within 7 days of receipt at kynbio.co@gmail.com and we will work to resolve the issue, including replacement or credit.
