Peptide Factory sells direct to researchers. The site says it has traded since 2012. It also produces and labels to order, so stock sold under other brand names may come from here.
In its own words: “We manufacture peptides tailored to your exact specifications — including sequence, purity, and quantity — for research, pharmaceutical, and biotech applications.”
Peptide Factory publishes 2 certificates of analysis on its site, all credited to Janoshik Analytical. The vendor chose which batches to publish, so those results do not tell you what is in the vial you receive. It advertises purity of ≥99%.
