Two brands, one company.

The question every first-time buyer asks, answered by us rather than by a forum. More on the about page.

Are you the same company as Wholesale Peptide Supply?

Yes — same company, same facility, same people answering the phone. Wholesale Peptide Supply is built for brand owners who need private label and fulfillment; Wholesale Amino Supply is built for buyers moving volume, where cost per vial is the whole conversation. More on the about page.

Which brand should I buy from?

If you are ordering 100 or more vials and care about cost per vial, you are in the right place. If you need under 100 vials, private label, or fulfillment, Wholesale Peptide Supply is built for that. The one link to it is on the pricing page.

Where are you located?

California. Orders are held and shipped from our facility there, Monday to Friday. Contact details are on the contact page.
