MOTS-C calculator

MOTS-C math uses the listed vial sizes on this card and the liquid you type. Concentration in mcg per mL is vial milligrams times 1000, divided by milliliters. A U-100 syringe has 100 marks per milliliter, so each unit is that concentration divided by 100. Example numbers so you can see the math: a 5 mg listing plus 2 mL of liquid. Change any number and the units change. Try the numbers. A research-market vial is not the same material used in a trial.

What is MOTS-C?

The name is a library listing for research vials. Some blends pair MOTS-c with humanin on a separate card. A blend is not two finished clinical programs. The mechanism language is mitochondrial and metabolic. It is not a fat-loss verdict.

Mitochondrial-derived peptide studied in metabolic signaling.

Regulatory status, dated 2026-10-09

FDA product approval

not established. No US therapeutic product approval is established by this curated source set; other countries and products may differ.

Compounding

not established. Compounded products do not carry FDA product approval; legal eligibility is not established here.

Research

investigational. Human therapeutic outcomes are not established in this catalog.

Sport

prohibited. WADA S4 lists MOTS-c.

What the cited papers actually measured

Lee et al. (PMID 25738459) introduced MOTS-c in metabolic-regulation models. Later human and review papers (including PMID 33473109) discuss exercise and aging. Those data are not product approval. They do not test research-market vials. Sport status is unverified on the catalog card.

We mark the cited papers as D. That is our label for how strong those papers are. It does not say the compound works.

How long it lasts, how you store it, listed sizes

The catalog does not record a single hour value. No verified formulation-specific human estimate in this source set; no guessed value is supplied.

Listed sizes are 5 mg and 10 mg. Use the vial label. This page does not invent a mix liquid or a throw-away date.

Risks and mix-ups already on the record

  • Safety is incomplete; absence of reports does not establish safety.
  • Unknown or incomplete for research formulations; this is not a clearance for use.
  • Unknown or incomplete; do not infer compatibility with medications or other substances.

People using PepBear often log: Existing clinician-directed records, symptoms and dated health measurements. Record missing data; trends do not demonstrate causation.

Questions people ask

Does limited human data mean MOTS-c does nothing?

Sparse trials do not prove “no effect.” They also do not prove a reliable effect in people buying research vials. The catalog keeps those as separate questions.

Is the MOTS-c / humanin blend covered here?

The blend has its own card. This calculator uses MOTS-c-only listed sizes.

How many units is a listed MOTS-C vial after you add water?

Units = (amount in mcg ÷ (vial mg × 1000 ÷ water mL)) × 100 on a U-100 syringe. Enter the three numbers. The chart shows the same math for each listed vial size and 1, 2 or 3 mL of liquid.

Why flag amounts under 5 units?

A U-100 barrel is easy to misread below about 5 marks. That is a measuring warning. The page does not tell you to take more.
