MENT half-life
MENT here is the acetate ester, which is fast-acting, with a half-life around 12 hours. A short half-life like this means levels rise and fall quickly, so it's dosed frequently to keep them steady.
What a half-life actually means
A half-life is the time it takes for half of what is in your blood to be gone. It does not mean the compound is finished at that point. Half goes, then half of what is left goes, and so on.
That is why the last traces take so much longer to disappear than the first. Most references treat something as effectively cleared after about five half-lives, which for MENT is roughly 2.5 days.
How MENT clears
| Half-lives | Time since dose | Roughly left |
|---|---|---|
| 1 | 12 hours | 50% |
| 2 | 24 hours | 25% |
| 3 | 36 hours | 12.5% |
| 4 | 2 days | 6.25% |
| 5 | 2.5 days | 3.125% |
These are round numbers from a single half-life figure. Real clearance shifts with dose, body composition, liver and kidney function, and what else you are taking. Treat it as a shape, not a schedule.
Why the timing matters
A short half-life means levels swing between doses, so timing and frequency do most of the work. A long half-life means levels build for days or weeks before they settle, so a change you make today might not show up for a while, and stopping does not clear things straight away.
MENT sits at about 12 hours, so it behaves like the short end of that range.
