Goal decision guide
Compare cognitive support options by stimulation profile, onset speed, evidence strength, and common dropout reasons.
These comparisons are educational triage notes, not treatment instructions. They are meant to help you compare evidence strength, tolerance issues, and practical tradeoffs before reading the full profile or speaking with a qualified clinician.
These are starting points for comparison, not recommendations, prescriptions, or guaranteed outcomes.
| Use-case context | Option to review |
|---|---|
| Calm concentration | L-Theanine |
| Stress-heavy workdays | Rhodiola |
| Immediate alertness | Caffeine |
| Compound | Potential fit | Typical timing window | Evidence context | Caution level |
|---|---|---|---|---|
| Caffeine | Fast alertness and reaction speed | 15 to 60 minutes | Moderate evidence | Needs review |
| caffeine l-theanine | Goal support | Timing varies | Strong evidence | Use caution |
| EGCG + Caffeine | Goal support | Timing varies | Moderate evidence | Use caution |
These badges are pulled from existing compound runtime profiles when available. Empty or pending fields stay conservative rather than inventing missing evidence, mechanism, or safety details.
