Southern Aminos

Southern Aminos is a US-based vendor selling peptides both retail and in bulk, with a broad catalogue spanning dozens of compounds. They host HPLC-tested COAs directly on their site, with reported purity running close to 99.5% — the testing is present, though the lab is not an independent third party. On pricing, they sit at the expensive end of the US market. Community feedback is not yet available, so how they perform on fulfillment and customer service remains an open question.
