California is the world's largest biotech hub, and ACS Peptide Testing Labs serves the entire state, from San Diego's Torrey Pines corridor to San Francisco's Biotech Row. Ship overnight for HPLC purity testing, COA verification, and comprehensive molecular analysis.
ACS Peptide Testing Labs serves California researchers and compounding pharmacies through overnight mail-in testing to our independent lab in Sun City Center, Florida. California 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 California.
ACS Peptide Testing Labs operates one facility in Sun City Center, Florida. We do not have satellite labs or partner facilities — every sample from California is shipped to and tested at the same Florida lab, by the same scientists, on the same instruments. Standard turnaround is 9–11 business days.
Overnight shipping from anywhere in California, next business day delivery to our Florida lab.
California leads the nation in biotech and pharmaceutical research, with over 4,000 life sciences companies and world-renowned institutions including UCSF, Stanford, UCLA, Scripps Research, and the Salk Institute. ACS Peptide Testing Labs provides independent third-party testing for this massive research ecosystem.
Most California submissions start with peptide purity testing by RP-HPLC at $150 per sample, then add LC-MS identity confirmation or third-party COA verification when a supplier certificate needs to be checked independently.
