Epitalon half-life & how long it lasts
Epitalon has a half-life of about 1 hours, reaches peak concentration around 30 minutes after a dose, and is practically cleared from the body about 5 hours after the last dose. Essentially no published human pharmacokinetic data; the figure is an estimate.
The numbers
| Half-life | 1 hours |
|---|---|
| Time to peak | 30 minutes |
| Route | injection |
| Typical cadence | short courses in most protocols |
| Practically cleared | 5 hours after the last dose (five half-lives, ~97% eliminated) |
| Steady state | after roughly 5 hours of continuous short courses in most protocols dosing |
| Evidence | limited human data — directional only |
What that means day to day
- Levels are never zero between doses. On a short courses in most protocols schedule with a 1 hours half-life, each dose stacks on what is left of the last one until steady state.
- Peak is not injection day. Concentration keeps climbing for about 30 minutes after the shot, so effects and side effects lag the dose.
- Stopping is gradual. After the last dose it takes about 5 hours for the compound to be practically gone.
- Read this one loosely. There is no FDA label or full human pharmacokinetic study behind this figure.

Track it instead of estimating it
Bo models this curve from your own logged doses, so you can see what is still in your system right now instead of doing the arithmetic. It also handles reconstitution math, dose reminders and injection-site rotation.
