Summary — API requirements by study
How to use this estimate: These figures are based on standard nonclinical study designs and assume solution formulation. Actual requirements will vary based on your specific protocol, formulation complexity, CRO requirements, analytical testing, and retention samples. Use this as a planning tool for early-stage API synthesis prioritization — confirm all quantities with your nonclinical team before ordering.
