Substances & compare

All 124 substances we carry — browse the A–Z glossary or the detailed table, then click any to line them up side by side.

Teal bars = benefits people seek, green→amber→red = side-effect risks — both 0–5, more = stronger.Information, not advice — facts only, never a "best" or "safest" pick. Try the screening advisor first.

The substance map

Every scorable compound at a glance: further right = better regarded by people who run it, higher = safer, bigger = more in demand. Zones are relative to what we carry; switch to Ranking to order by goal or by value per €.

Bubble size = demand, not our stock. Quadrants split at the catalogue median, so every zone is relative to what we carry — the red line is the absolute one.Scroll or +/− to zoom, drag to pan, click a bubble to open it.

Data provenance: substance class, half-life and mechanism are compiled from medical and pharmacology references and cross-checked. The benefit and side-effect ratings are relative 0–5 estimates synthesised from that literature and established community/clinical consensus — useful for comparison, but AI-compiled and pending expert review (0 of 124 compiled, 124expert-reviewed). Where we don't yet have data a figure shows as "—" rather than a guess. Prices, offers and ratings come from live listings. None of this is medical advice or a recommendation to use these compounds.
