Frequently asked

How do I check a lot?

Enter the lot code printed on the vial — or the compound name — in the verification widget. It returns the compound, the net content, the published purity, and the report number for that exact lot.

Why does each size have its own lot?

Because each fill size is a separate production run. A 5 mg vial and a 10 mg vial of the same compound are tested separately and carry different reports. Selecting a size on a product page switches the lot, the certificate, and the batch history with it.

What happens when a lot sells out?

It stops being orderable but its report stays published, and it stays searchable in the verification widget. Past reports are part of the record, not marketing material to be removed.

How fast do orders ship?

Stocked references dispatch within 24 hours on business days. Made-to-order references take 10 to 15 business days. Everything ships insulated with a cold-pack; express adds dry ice.

Do you ship outside the EU?

Checkout currently covers France, Belgium, Luxembourg, Germany, and Switzerland. VAT is applied at the destination country's rate.

Can I order at wholesale pricing?

Wholesale terms start at a minimum order quantity per product. Ask us for the current line sheet — retail prices shown on this site already include the standard markup.
