Frequently asked
What is in the Copper & Cosmetic research class?
3 compounds across 8 specifications, priced from $28.60. Research classes are catalog navigation groupings only and are not statements about biological activity or intended use.
Are certificates of analysis available for these materials?
Yes. A COA is available by request for the batch supplied, covering HPLC purity and mass-spectrometry identity confirmation.
What does shipping cost?
Carts of single vials and bacteriostatic water ship for $20.00. Any cart containing a kit ships for $50.00 standard or $80.00 expedited, with single vials and bacteriostatic water included free. From 4 kits upward the rate drops to $30.00 standard or $50.00 expedited. Bacteriostatic water is a diluent and never counts as a kit. Anywhere outside the United States ships for a flat $80.00, whatever the cart holds. Shipping is added at checkout and revalidated on the server before the order is accepted.
