Ordering for universities and labs
TressVita supplies research peptides to university, hospital-research and biotech labs across the United States, with the paperwork a purchasing office needs.
How lab orders work
- Open a business account. Every lab is verified before its first order: your institution’s details, the contact’s ID and a short call. See business accounts.
- Ask for a quote. Once approved, send the products, vial sizes and quantities to members@tressvitalabs.com, or order online.
- Get a formal quote. We reply with pricing, shipping and the certificate of analysis for each lot we would ship.
- Pay the invoice. We send an invoice through Stripe. Orders ship once the invoice is paid.
- Receive and verify. Orders ship within one business day of payment. Each vial’s lot number matches its certificate, which you can also look up online.
Paperwork and pricing
- W-9: available on request for vendor setup.
- Quotes and invoices: itemized, with lot numbers available before purchase.
- Payment terms: invoices are paid before shipping. We don’t offer net terms.
- Business accounts get free 3-day shipping. See business accounts.
Documentation for your records
Every lot is tested before release. Identity is confirmed by mass spectrometry against the expected molecular weight, and purity by reversed-phase HPLC. Water content, acetate content and endotoxin are reported where the method applies. See how we test, how to read a certificate and how to verify a compound’s identity.
Research use
All products are supplied for laboratory research only and are not for human or veterinary use. Orders are subject to our terms of sale. We ship to U.S. addresses only, from South Florida.
