Frequently Asked Questions

Everything researchers ask us before ordering.

What are research peptides?

Peptides are short chains of amino acids used as reference materials in laboratory and scientific research. Every compound we sell is intended strictly for in-vitro research and laboratory use only.

Are your products for human consumption?

No. Vertex Peptide Lab products are not for human or veterinary use, and are not intended to diagnose, treat, cure, or prevent any disease. They are sold to qualified researchers aged 18 or older.

How pure are your peptides?

Our compounds are tested to 99% purity by HPLC. Certificates of Analysis (COAs) are available on request for most catalog items.

How fast do you ship?

In-stock orders are processed within 1–2 business days and shipped from within the USA with tracking. Most domestic orders arrive in 3–5 business days.

What payment methods do you accept?

Accepted payment methods are shown at checkout. If you have any trouble completing an order, contact us and we’ll help.

How should peptides be stored?

Lyophilized (freeze-dried) peptides should be stored cold and away from light. Once reconstituted, keep refrigerated and use within the timeframe appropriate to the compound.
