Research toolkit

Tools

Built on the same indexed dataset as our substance library. Every dose, half-life, and interaction warning is sourced and dated.

Stack Builder

Compose a stack from any indexed substance. Live cost rollup, safety scoring, and pairwise interaction warnings.

Drop in any combination and see pairwise interactions colored by severity, with cited notes.

Pick what you're optimizing — focus, sleep, memory, mood — and get matched stacks ranked by evidence and safety.

Personalized dose ranges adjusted for body weight, tolerance level, and timing.

Filterable index of every cited benefit and study in our database. Linked to PubMed.

Find curated stacks that match your daily budget. Cost per day, per month, per ingredient.

For substances that build tolerance (caffeine, modafinil, phenylpiracetam), plan on/off weeks.

Log focus, mood, energy, sleep on 1-10. Trends emerge after 2-4 weeks. Data stays in your browser.
