84 of 84 listings at 5 mg, sorted grade first, then price per mg.
LL-37 5 mg was first read on 2026-09-30. Middle price $14.3 per milligram across 78 sellers. A week-by-week line appears after the next finished weekly walk. One week is a snapshot, not a history.
The figure is the same ungated market median the range on this page uses: every seller found. Certificate tier still ranks the cards. The purity gate is written and off, so this is not a tested-sellers-only series.
We never charge for knowledge. No vendor has a say in what a page says. Sellers are ranked by the certificate they publish, then by price. Every size of LL-37 · Laboratories named
