Vial duration math

Estimate full uses and calendar duration from an available amount, an amount per use, and a cadence you select. This tool does not apply an implicit 28-day or other discard rule.

The cadence is user-entered calculation context, not a recommendation.

Formula

full uses = floor(available mg ÷ amount per use mg) duration days = round(full uses ÷ uses per week × 7)

Calendar duration does not determine sterility, beyond-use dating, storage, or discard timing. Follow product-specific instructions and qualified professional guidance.
