ACS Peptide Testing Labs serves Arkansas researchers and compounding pharmacies through overnight mail-in testing to our independent lab in Sun City Center, Florida. Arkansas clients ship 100–500 µg of lyophilized peptide via FedEx or UPS overnight; samples are analyzed by reverse-phase HPLC for purity, LC-MS for identity, and optional LAL endotoxin, Karl Fischer moisture, and ICP-MS heavy metal screening. Signed Certificates of Analysis are delivered electronically in 9–11 business days, with no in-person drop-off required anywhere in Arkansas.
