This happened to me last month and I still don’t totally know what to make of it.
Three new sellers appeared in the last six weeks with suspiciously similar site templates.
Prices moved noticeably this month across several vendors at once, which usually means something upstream changed.
If this has already been answered somewhere just point me at it.

Short answer: check that the lot number on the certificate matches the lot printed on your vial. If it does not, the document is about different material.
