Frequently asked questions
If your question is not here, reach out through the contact page.
Are these products for human use?
No. Our products are sold strictly for laboratory and research purposes and are not for human or animal consumption. They are not drugs, supplements, or medical devices, and have not been evaluated by the FDA to diagnose, treat, cure, or prevent any disease.
What does lab-tested mean here?
Every batch is tested by an independent third-party lab for identity (mass spectrometry) and purity (HPLC). A Certificate of Analysis is available for the batch you receive.
Can I see a COA?
Yes. We are happy to share an example Certificate of Analysis on request, and you receive the COA for your specific batch when you order.
How do I buy from LNK Peptides?
Access starts with a short application. You tell us who you are and what kind of research you're completing, and our team reviews your application. It adds a layer of accountability and protects both sides. Once you're approved, you can sign in to see pricing, sizes, and COAs and place an order.
How long does approval take?
Our team reviews each application one by one. You'll usually see approval within 2 to 3 business days, and someone from our team will reach out before you're approved.
Do you sell research peptides outside of Lincoln, Nebraska?
Our base is Lincoln, Nebraska, and we serve Lincoln, Omaha, and the surrounding areas with local delivery and pickup. Shipping is available on request for researchers further out. All orders remain strictly for laboratory and research use only.
What purity standard do you hold?
We hold a high-purity standard of 99% or higher by HPLC and reject material that does not meet it.
