Researchers familiar with established peptide brands expect documented quality. Lone Star Peptide Co. meets that bar with Freedom Diagnostics independent testing — HPLC, LC-MS, and endotoxin on every batch — and a publicly searchable COA library available before you order.
Researchers who have used established peptide brands know what good documentation looks like. They expect independent testing, batch-specific COAs, and a supplier who can answer technical questions about methodology.
Lone Star Peptide Co. uses Freedom Diagnostics for all testing — an independent ISO-accredited laboratory with no commercial interest in the results. Every batch receives HPLC purity verification (≥99%), LC-MS identity confirmation, and LAL endotoxin testing.
All COAs are publicly searchable at lonestarpeptideco.com/coa/ before placing an order. You can review the HPLC chromatogram, LC-MS mass spectrum, and endotoxin results for any batch before purchase.
Orders placed before 3 PM CST ship the same day from our Houston facility. Texas researchers receive most orders within 1–2 business days with cold-chain packaging.
