Talk to us.
TWO+DOS is the trading name of Two Plus Dos Research LLC, a United States supplier of lyophilized compounds for laboratory research use only.
Email is the fastest route and reaches the same people who handle documentation requests. We read and reply during US business hours.
What we can help with
- Certificates and documentation
- Send the lot number printed on the vial and we reply with the certificate of analysis on file for that lot. No account is needed. See how our certificates work.
- Order questions
- Status, tracking, address corrections, and anything that went wrong with a shipment.
- Wholesale and bulk
- Volume and recurring supply enquiries for laboratories and institutional buyers.
- Quality and testing
- Questions about methods, lot traceability, or what a result means. Our quality procedures page covers most of it.
What we do not provide
We do not provide dosing, administration, protocol, or use instructions, for any compound, to anyone. We are not a pharmacy and we give no advice on use in humans or animals. Requests of that kind are declined. What we do provide is documentation: identity, purity, method, and the lot number that ties a certificate to the vial in your hands.
