| Time to effects | Subjective stimulant effects are sometimes reported within hours of taking a dose in informal user accounts, but no controlled study in healthy, adult humans has confirmed a clear time course or the actual magnitude of any effect. | Not applicable — HRV is a monitoring indicator, not an intervention; changes in the trend become visible after several days to weeks of observation. |
| Who it's for | There's no well-established target group in Western markets, where the substance isn't an approved drug or legal supplement | Athletes wanting to objectively monitor training load and recovery |
