Frequently asked questions
If your question is not here, reach out through the contact page.
Are these products for human use?
No. All products are sold strictly for laboratory and research purposes only. They are not for human consumption and are not drugs, supplements, or medical devices.
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.
Why do I need to apply?
A short application keeps sourcing accountable and confirms a legitimate research use. It protects both sides and keeps our catalog compliant.
How long does approval take?
We review each application to confirm a legitimate laboratory or research use, usually within one business day.
Do you serve researchers outside Lincoln?
Our base is Lincoln, Nebraska, and we prioritize local and regional research users. Apply and we will confirm what we can support.
What purity standard do you hold?
We hold a high-purity standard of 98% or higher by HPLC and reject material that does not meet it.
How should I store research peptides?
Keep lyophilized powder frozen and dry. Once reconstituted, aliquot and minimize freeze-thaw cycles. See our research notes for handling details.
