Quality Standard
Purity is the percentage of your peptide that is actually the intended compound. Everything else is contamination — and contamination changes your results.
What's in the other ~3.5%?
Synthesis Byproducts
Failed or incomplete chains produced during manufacturing that mimic your peptide but behave differently in research.
Residual Solvents
Chemical solvents used in the production process that aren't fully removed during purification.
Misfolded Chains
Peptide chains that assembled in the wrong sequence or orientation — structurally different from what you ordered.
Endotoxins
Bacterial contamination introduced during handling that can trigger inflammatory responses and skew results.
