Humanin vs MOTS-c
Humanin sits in longevity, while MOTS-c sits in metabolic — so despite being mentioned together they are used for different things. The table below sets out the differences. We give no dosing guidance.
Side by side, in plain English — what each one is, where they overlap and where they genuinely differ.

The differences that actually matter
They aren't really substitutes: Humanin sits in Longevity while MOTS-c sits in Metabolic. People usually pick between them because of a shared secondary effect rather than because they do the same job.
Where they overlap: insulin sensitivity.
Reported mainly for Humanin: neuroprotection, longevity markers.
Reported mainly for MOTS-c: enhanced exercise capacity, fat oxidation.
What Humanin is
Humanin is a naturally occurring mitochondrial-derived peptide, produced from a short open reading frame within the mitochondrial genome. It is understood to exert its biological effects through interactions with various cellular components, notably by binding to certain cell surface receptors such as components of the ciliary neurotrophic factor (CNTF) receptor complex, including CNTFRα, gp130, and LIFRβ. Furthermore, it is reported to interact with insulin-like growth factor binding protein 3 (IGFBP-3), thereby i
What MOTS-c is
MOTS-c is a mitochondrial-derived peptide recognized for its role as a mitokine, acting as a signaling molecule that communicates the metabolic status of mitochondria to the rest of the cell and body. It primarily influences systemic metabolism by enhancing insulin sensitivity, particularly within skeletal muscle and liver tissues. This peptide appears to exert its effects by modulating glucose utilization and fatty acid oxidation, partly through pathways involving AMP-activated protein kinase (AMPK) activation. By
How to compare them for yourself
Anecdotes online are noisy because nobody is measuring the same thing. The only comparison that means anything is your own: log each entry with a timestamp, keep the vial ledger honest so you know what you actually got through, pick two or three metrics before you start, and look at the trend after several weeks rather than day to day.
Peptide Wizard does that part for you — Humanin and MOTS-c are both in the built-in reference library with a 3D vial, and your history, vial ledger and cost per entry stay private on your device.
FAQ
What is the difference between Humanin and MOTS-c?
They aren't really substitutes: Humanin sits in Longevity while MOTS-c sits in Metabolic. People usually pick between them because of a shared secondary effect rather than because they do the same job.
Can you log Humanin and MOTS-c in the same period?
Plenty of people record more than one peptide at a time. Peptide Wizard keeps a separate vial ledger and entry history for each, so you can see exactly what overlapped and when — it does not recommend combinations or doses.
Which is better, Humanin or MOTS-c?
There isn't a universal answer — reported responses vary a lot between individuals, which is why your own log is more informative than anyone else's anecdote. Track one variable at a time and compare your own metrics over several weeks.
