PRACTICAL QUESTIONS
Before you get started
How do I find a peptide manufacturer for my project?
Start with intended use and a written specification. Ask suppliers about relevant scope, test methods, batch documentation and sample availability. Tangdou can help organize the inquiry; technical suitability must be independently assessed.
What do I need before asking for an OEM quote?
Provide the specification, quantity, destination, intended use, packaging needs and required documents. If a requirement is undecided, mark it as an open question rather than assuming a capability.
Can I use a sourced peptide in a consumer or medical product?
This depends on the substance, intended use and destination rules. Obtain qualified regulatory and technical advice before sourcing or making claims. This service does not establish approval, safety or suitability.
