# Sparta Labs

> Sparta Labs is a United States supplier of research-grade, research-use-only (RUO) peptides. Every compound ships with a per-batch, independent third-party Certificate of Analysis (COA) with identity and purity confirmed by HPLC. Nothing sold is a drug or a dietary supplement, and none of it is intended for human or veterinary consumption, diagnosis, or treatment. Content is educational reference material, not medical advice.
