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.
