Frequently asked questions

Are your peptides intended for human use?

No. All compounds sold by SMLabs are strictly for in-vitro research and laboratory use — not for human or veterinary consumption.

What purity standards do you guarantee?

Every lot is tested by reverse-phase HPLC and verified by mass spectrometry, with a standard minimum purity of >99%.

Do you provide a Certificate of Analysis?

Yes. A lot-specific COA with chromatogram, mass spec data, and purity percentage is included with every order.

How should products be stored?

Products ship lyophilized. Store at -20°C protected from light; reconstituted peptides should be refrigerated and used within 14–28 days.
