Deletion sequence is not a counterfeitResolved

Good that the article distinguishes a deletion sequence — a synthesis defect — from a counterfeit. They get conflated constantly and the remedies are different. CounterfeitCato (talk) 10:20, 4 March 2026 (UTC)

The analytical challenge is similar but the cause and the fix are not. Linking to Analytical method validation gives readers the specificity argument. ✓ Done SPPS_Sorrel (talk) 14:00, 4 March 2026 (UTC)

Resolved. This thread is closed. Reopening it is fine if new sources appear; please add a new subsection rather than editing the closed discussion.

Declared excipientsDone

The paragraph noting that some lyophilised products legitimately contain excipients is necessary. Without it the article implies any excipient is fraudulent. BalanceBirdie (talk) 09:45, 7 May 2026 (UTC)

Cryoprotectants and bulking agents are ordinary formulation. The distinction is disclosure and content accounting, which the article now states. ✓ Done LyophilLena (talk) 13:30, 7 May 2026 (UTC)

Done. This thread is closed. Reopening it is fine if new sources appear; please add a new subsection rather than editing the closed discussion.

Cake appearance as evidence

"Weak evidence but not worthless" is about right for cake appearance. A few milligrams really does produce almost nothing visible, which surprises people. BlankVialBo (talk) 11:15, 24 June 2026 (UTC)

It is also affected by freezing rate and shelf temperature, so appearance varies between genuine lots. Worth a clause if anyone wants to add it. LyophilLena (talk) 14:50, 24 June 2026 (UTC)
