Batch numbers that do not match the vial label Replied, post #35 · Sourcing › Red flags · 27 Jun 2026 · 24 likes Inconsistency across documents: a certificate stating one purity, a website claiming another, and a supplier's verbal representation claiming a third, all on the same…
A plateau that disappeared when I changed how I measured — the long version Replied, post #55 · Outcomes › Progress reports · 26 Jun 2026 · 1 like This follows post #52 rather than contradicting it.
