MOTS-c Half-Life Calculator
MOTS-c is a mitochondrial-derived peptide — encoded in mitochondrial DNA rather than the nucleus, which makes it genuinely unusual. Its half-life is short, and this calculator charts what that means across an every-other-day interval.

At every other day, each dose has essentially cleared before the next one — levels don't accumulate, they repeat the same rise and fall. Clearance after a dose takes about 7.5 hours.
This is a modelled estimate of relative levels from published half-life and time-to-peak figures — not a measured blood concentration. Individual pharmacokinetics vary.
Based on a published MOTS-c half-life of about 1.5 hours. The chart models RELATIVE levels from a unit dose — enter your own figures to see the shape. It is not a dose recommendation.
What a 1.5 hours half-life means in practice
A half-life of 1.5 hours against every other day dosing means each dose has essentially cleared before the next arrives. That shapes the curve in three ways:
1. One half-life
Half the dose is gone after 1.5 hours. After two half-lives 25% remains, after three 12.5%.
2. What's left at the next dose
Dosing every other day means the next dose lands 2 days later, with about 0% of the previous one still present.
3. Accumulation and plateau
Almost nothing carries over, so levels don't accumulate — each dose repeats the same rise and fall, clearing in about 7.5 hours.
Worked example
MOTS-c has a half-life of 1.5 hours. Dosing every other day, the next dose arrives 2 days later with about 0% of the previous one still on board. That's little enough that levels don't build up: each dose rises and falls on its own, clearing in about 7.5 hours.
Encoded in mitochondrial DNA
Almost every peptide in the body is encoded in nuclear DNA. MOTS-c belongs to a small class encoded in the mitochondrial genome, discovered relatively recently, and the finding that mitochondria produce signalling peptides at all was itself notable — it implies a communication channel from mitochondria to the rest of the cell that was not previously mapped.
The research examines metabolic regulation and exercise-related pathways, largely in cell and animal models. Its half-life is short enough that on a multi-day interval each administration clears completely before the next, so nothing accumulates.
