Clarity on every lot.
What is actually in the vial? A label, a product page and a price cannot answer that. Only a laboratory can.
An independent laboratory report for the exact lot, with identity and purity measured by HPLC and mass spectrometry, and the batch number on your vial matching the certificate in your box.

What does Retabionix supply?
Research peptides for laboratory use. Peptides are short chains of amino acids studied in laboratory settings. Everything we supply is for laboratory, analytical and educational purposes.
All Retabionix products are for laboratory research use only. They are not drugs, foods, cosmetics or medical devices. They are not for use in people or animals, and are not intended to diagnose, treat, cure or prevent any disease. These products have not been evaluated by the Food and Drug Administration.
How do I know what is in the vial?
Each lot is sent to an independent laboratory before it is listed. The laboratory confirms identity and measures purity by HPLC and mass spectrometry. The certificate of analysis (COA) for your exact lot ships in the box, and the batch number on the vial matches it.
Why can some strengths not be ordered?
A strength can be ordered only once its current lot has been checked against a laboratory report. Until then it stays listed, marked as awaiting lot verification, so you can see the specification without being sold an unverified lot.
Who can order?
Qualified researchers aged 21 or over, and people buying for a research laboratory, institution or business. We ask you to confirm this before you order and keep the confirmation on file.
Do you give guidance on preparing or using the material?
No. We publish the certificate for each lot and the storage condition on the label, and nothing beyond that. Whether a material suits your research is for you or your institution to decide.
Do you sell water or other supplies?
No. We supply research materials only. We do not sell water, consumables, or any preparation or delivery equipment, and we will not source them on request.
Where do you ship?
Within the continental United States only. Orders of $150 or more ship free; under $150, shipping is a flat $10. Order by 4pm ET on a weekday and it ships the same day, with tracking.
