Every market development we have covered, newest first.

Short answer

3 dated market items. Most recent: Compounded GLP-1 access consolidates toward smaller operators (2026-06-15).

Market items track who is actually selling, which has changed more than the medicine has.

Why market developments matter here

The large consumer platforms have largely left compounded GLP-1, and what remains at the cheap end is a field of smaller operators with variable disclosure. Brand recognition no longer does the diligence for you.

This matters for reading older comparisons: several programmes still ranked in round-ups no longer sell the product being compared. Check the verification date on any list before trusting its order.
