Where to Buy MOTS-c in the UK
MOTS-c is a comparatively new research compound, and UK availability outpaced documentation standards. This guide covers the analytical data a supplier should publish, the vial and pen options available, and UK delivery and storage.

Overview
What Is MOTS-c?
MOTS-c is a mitochondrial-derived peptide encoded in mitochondrial DNA rather than the nuclear genome, which makes it unusual among research peptides. It is investigated in metabolic signalling and cellular energy models. It is supplied as a lyophilised powder in a sealed vial, and as a pre-filled research pen.
Classification
Mitochondrial-derived peptide
Format supplied
pre-filled pen or vial
Origin
Encoded by mitochondrial DNA rather than nuclear DNA
Residue count
16 amino acids, methionine-containing
Purity specification
99% minimum by HPLC with the trace included in the batch pack
Research use only
Not a medicine. Not for human or veterinary consumption.
Available Options
MOTS-c Options Available From Arma Peptides
MOTS-c is supplied in two lyophilised vial sizes. The larger vial is cheaper per milligram but commits you to a single reconstitution, so match it to the length of your run.

Due Diligence
What Makes a MOTS-c Batch Worth Buying
MOTS-c is a mitochondrial-derived peptide, and it is short, hydrophobic and awkward to purify. Those three properties dictate the checks.
- STEP 01
Hydrophobicity Causes Recovery Problems
MOTS-c sticks to surfaces and to itself. A supplier who cannot tell you the peptide content, as opposed to the HPLC purity, may not know how much peptide actually survived into the vial.
- STEP 02
Sixteen Residues, Methionine-Rich
The sequence contains methionine, which oxidises. A COA with an analysis date close to your order date matters more here than on an oxidation-resistant peptide, because the profile drifts on the shelf.
- STEP 03
Solubility Notes Should Be Provided
MOTS-c does not always dissolve cleanly in plain bacteriostatic water at higher concentrations. A supplier who has actually handled the compound will tell you this before you order rather than after.
- STEP 04
Beware Vague Mitochondrial Marketing
Listings that lean on mitochondrial language and provide no analytical data are selling a story. The only things worth reading are the chromatogram, the mass-spec confirmation and the lot number.
This compound is sold for in-vitro and laboratory research only. It holds no UK marketing authorisation and must not be administered to humans or animals.
Handling & Delivery
Dissolving and Storing MOTS-c
Most MOTS-c complaints are dissolution problems misread as potency problems.
Start Dilute
Reconstitute at a lower concentration than you would a hydrophilic peptide, then concentrate if needed. Forcing a high concentration produces visible haze and unrecoverable aggregate.
Protect From Oxidation
Because of the methionine content, minimise headspace air and time on the bench. Cap immediately and return the vial to refrigeration between uses.
Low-Binding Labware
Use low-binding tips and glass where possible. A hydrophobic 16-mer left in standard polypropylene loses a measurable fraction of its nominal concentration to the plastic.
Dispatch and Cover
Same working day dispatch before the cut-off, tracked, plain outer packaging, fast UK & EU delivery from Arma Nova Pharma, and 48-hour photographic damage cover.
FAQ
MOTS-c in the UK: Questions Researchers Ask Before Ordering
+Is MOTS-c legal to buy in the UK?
Yes, for laboratory research. It is not a licensed medicine and must not be supplied or used for human or veterinary consumption. Research purchase is lawful; intended use is the purchaser’s responsibility.
+What is a mitochondrial-derived peptide?
A peptide encoded within mitochondrial DNA rather than the nuclear genome. MOTS-c is among the most studied of this small class, which is why it appears in metabolic and cellular-stress research models.
+Why does my MOTS-c look hazy after reconstitution?
Almost always concentration. MOTS-c is hydrophobic and will not go fully into solution in plain bacteriostatic water at high loads. Dissolve more dilute and warm gently to room temperature before assessing.
+What makes MOTS-c different from other research peptides?
It is encoded in mitochondrial DNA rather than nuclear DNA, which is why it is described as a mitochondrial-derived peptide. That places it in a different category from synthetic analogues and secretagogues.
+Is the pre-filled pen the same compound as the vial?
Yes — the same compound at the same 99% minimum HPLC specification. The pen arrives pre-filled and requires no reconstitution; the vial contains lyophilised powder and gives control over concentration.
+Does MOTS-c oxidise on storage?
The methionine residue is susceptible, so sealed vials should be kept cold and dark and reconstituted solution should have minimal air exposure. This is a real difference from peptides with no oxidisable residues.
+What documentation ships with the order?
A batch-specific Certificate of Analysis carrying the lot number on your vial, the analysis date, the method, the testing laboratory, the HPLC chromatogram and mass-spectrometry identity confirmation.
+Can I return an unopened vial?
Yes, inside 14 days of receipt while unopened and in original sealed packaging. Unsealed vials are excluded for health-protection reasons; statutory rights on faulty goods are unaffected.
