What countries do you ship to?

How should peptides be stored?
Sealed lyophilised vials should be stored at −20°C, away from light and moisture. Once reconstituted, store at 4°C and use within 28 days — do not refreeze. Storage details are listed on each product page.
How do I reconstitute lyophilised peptides?
Inject bacteriostatic water slowly down the side of the vial — never directly onto the powder. Swirl gently to dissolve; do not shake. Allow to stand until fully clear. Each product page includes a compound-specific reconstitution guide.
Do products come with COAs?
Certificates of Analysis are not available at launch. All compounds are HPLC-verified to ≥99% purity. We will confirm COA availability as soon as it is provided by our supplier.
What payment methods are accepted?
Accepted payment methods are confirmed at checkout. For wholesale and B2B enquiries, contact us directly for available options.
Are these products for human use?
No. All Vexar Lab compounds are sold strictly for in-vitro research and laboratory use only. They are not for human consumption, are not medicines, and are not approved for therapeutic use.
What is your returns policy?
Due to the nature of research chemicals, returns are accepted only for items that arrive damaged or incorrect. Contact us within 7 days of delivery with your order number and batch details. Opened or reconstituted vials cannot be returned.
