The toolkit
Built to make the evidence usable.
A reference is only worth so much without tools to put it to work. Codex ships the analyzer, the calculator, the comparison engine, and the marker reference — every tool designed around the same evidence-first methodology that backs the grades.
-
Lab interpretation
Bloodwork analyzer
34 markers triaged against ranges that reflect what you're actually running — long-ester androgens, orals, GH, GLP-1, SARMs. Drop a LabCorp/Quest PDF, paste portal text, or enter values manually.
- PDF + drag-and-drop import
- Multi-draw history with trend sparklines
- Protocol-aware flag severity
- Deep-links to per-marker explainers
-
Companion to the analyzer
Marker reference
What each lab value actually means — definition, standard range, enhanced-context optimal, what pushes it up, what pushes it down, and when to act. 34 markers across hormones, thyroid, lipids, metabolic, organ, and CBC panels.
- Direct anchor for every analyzer flag
- Plain-English drivers per marker
- Protocol-specific context per marker
-
Peptide math
Reconstitution calculator
Per-syringe-mark conversion for any vial concentration. Pairs with a mg/mcg/ng/g unit converter on the same page. Measurement math only — never a dose recommendation.
- Insulin-syringe-mark output
- Holds-per-vial accounting
- Unit converter on the same page

The 1–10 rubric
The Codex Scale
The single rubric every compound is graded against. From 10 (Established · FDA-approved + meta-analyses) down to 1 (Unsupported · marketing or anecdote only). Includes the current grade distribution across all 100 compounds.

Every tool is educational — interpretation, math, and reference, never dose recommendations, protocols, or vendor links. See standards for the editorial posture and the Codex Scale for how the grades work.
