Anonymous side-effect patterns

Rough heatmap of anonymous side-effect and positive-signal tags — a "most-mentioned" snapshot, not safety or efficacy advice.

No anonymous side-effect reports yet. When reports are submitted, this panel will show a simple heatmap of tags like "nausea", "flushing", "improved healing", and more.

How to read these logs

Each entry is a single, anonymized “n=1” summary with relative change sliders from −5 to +5. Higher positive values indicate perceived improvement; negative values indicate perceived worsening.

Context (training level, age band, duration, and dosing frequency) is shown so you can quickly skim for patterns or outliers. Treat this as qualitative signal layered on top of study data, not as a substitute for controlled trials.

Anonymous side-effect reporting (detail)

This section describes how anonymous side-effect reports are aggregated into the heatmap above. Reports are anonymous and unverified, and should be read alongside primary safety data.

Use the "Report side effects" button to open a focused popup form. Please keep descriptions neutral and avoid medical language; think in terms of "nausea", "flushing", "vivid dreams", etc.
