Semax price trends
What Semax has cost per milligram across the vendors we track, read from their own listings and dated. US dollar listings only, and rises as readily as falls — it is an index, not a buying prompt.
- Semax
47 readings between 24 Aug 2026 and 12 Oct 2026, over which the average rose 37%. Each point is the mean of every confirmed listing we held that day, so a vendor arriving or leaving moves it as much as a price change does.
