MOTS-c is a 16-amino-acid mitochondrial peptide. Because synthesis is harder than standard linear peptides, purity issues are very common in grey-market product.
Mitochondrial-derived research peptide
Why test MOTS-c?
MOTS-c often shows up under 90% purity even from established vendors. Quantitative HPLC also catches under-filled vials.
Common issues we find
Low purity (<90% HPLC)
Under-fill
Truncated sequences from poor synthesis
Frequently asked questions
What purity should MOTS-c be?
Reference-grade MOTS-c is ≥97% by HPLC. We frequently see Australian grey-market product land between 85-93%.
