The books.

Three standalone volumes on one research standard — a per-compound reference, a stack-pairing guide, and a fact-checked history. Every dosing claim was cross-referenced across 50–100 independent sources, then handed to a pass built to refute it, before it was allowed to print.

Each is a print-quality PDF — bought once, no subscription, no account required. Real pages from every book are below, exactly as they print. Or get all three at once ↓

Reference, Scheduling & More

83compounds
10sections
59pages

Eighty-three compounds and blends, one card each. Every card carries two independent signals — an evidence tier for how much real human data exists, and a community rating for how consistently sources report it working — plus the documented dose ladder from starting figure to target, and spec pills where the vial, water, concentration, and syringe-unit arithmetic is already done.

Where an official trial protocol and documented community practice genuinely differ, the card states both, clearly labelled. Built for looking a compound up mid-thought, not reading front to back.

Every card in the book follows this exact anatomy — name, score, grade, evidence tier, ladder, pills — so once the first card makes sense, all 83 read at a glance.

26stack records
9sections
57pages

Twenty-six combination records. Each stack card scores the pairing, states the mechanism reasoning it rests on, then lays the protocol out per compound — dose, frequency, timing, and route side by side, with the shared cycle stated once.

Scheduling is written for compounds running together, not copied from their solo entries — and every record carries a product photograph and a labelled mechanism diagram alongside the pills.

Knowledge, History & More

25profiles

79pages

Twenty-five discovery stories, written to be read: who found each compound, what actually happened, and how much of the told-and-retold version holds up. Every profile's central claim carries a fact-check verdict — true, myth, or embellished — from the same adversarial pass the dosing figures get, with the specific correction stated rather than a vague “sources differ.”

It is set apart on purpose: its own serif, magazine-style pages, a year pill on every profile, and a vintage-naturalist illustration plate for each one.
