VialCheck Team 8h ago 1. First-hand experience only — say whether you handled the vial yourself or are passing something on. 2. Batch numbers, labs and dates. A vendor can't answer an adjective. 3.

Downvote what's unhelpful, report what breaks the rules. Posts are members' own views, not VialCheck's. Research discussion only — nothing here is medical advice.
