Declare the composition
Powders may use drying carriers; liquids may use ethanol, water, glycerin or other agreed systems. Carrier identity and composition influence handling and application suitability. Ask for a meaningful composition statement rather than a headline strength alone.
State mass and volume clearly
Kilograms, litres, milligrams of extract and milligrams of alkaloid are not interchangeable. Use measured concentration and density when a mass-to-volume conversion is needed. An extract ratio is not a substitute for a measured final composition.
Qualification is application-specific
A carrier suitable for one oral formulation does not prove suitability for inhaled or nasal delivery. Evaluate the finished format and its route-specific evidence separately. This is a formulation and quality question as well as a sourcing question.
