Overview#

CPC Scientific (CPC Scientific Inc., cpcscientific.com) is a legitimate, long-established B2B peptide CRDMO — NOT a retail research-use-only storefront. FIT: it sells peptides directly relevant to this directory: research-grade custom and catalog peptides, cGMP peptide APIs, oligonucleotides, and peptide-oligo conjugates, by quote/contract to pharma, biotech, and academic clients. U.S. presence is real and substantial: U.S. company established in Delaware in 2005 (per parent Medtide Inc.'s HKEX filing — NOT California-formed as sometimes assumed), headquartered today in Rocklin, California (3880 Atherton Rd, 41,000 sq ft API facility announced 2022), after Sunnyvale/San Jose/Milpitas, with the domain registered 2005-04-26. It is a wholly owned subsidiary of Medtide Inc. (HKEX: 3880.HK, listed 2025-06-30); named leadership is public (founder/CEO Shawn Lee; President Theresa Tao Cheng; COO Irvine Skeoch). Manufacturing is centered on the group's Hangzhou cGMP plant, which reports five FDA inspections (2011-2024, first four with no Form 483), a 2026 FDA Pre-License Inspection, and FDA DMF 043979 for tirzepatide API. All defined regulatory searches — FDA warning letters, recalls, FTC, state AG, civil litigation, criminal/injunctive — returned No Record Found; the only import-alert point is a tier_3-reported favorable one (semaglutide API on the Import Alert 66-80 Green List), unverified directly on fda.gov in this pass. Testing is in-house cGMP release testing (HPLC/UPLC, MS, AAA, endotoxin, ICP-MS, etc.); there are no public COAs, no verification portal, and no published payment, refund, or terms policies — all consistent with the contract-manufacturing model and recorded as Unknown where unpublished, rather than scored as storefront red flags. Open items: Secretary of State standing and registered agent could not be verified in this pass (Delaware/CA records require interactive lookup; no indexed record surfaced), and the vendor site publishes no street address. No serious (High/Critical) findings.

Evidence ConsistencyGenerally consistent, with two presentational points a reviewer should note: (1) founding year is marketed as 2001 (the Chinese group's founding) while the U.S. company dates to 2005; (2) headquarters geography has moved Sunnyvale → San Jose/Milpitas → Rocklin while the (408) phone and sales email have remained constant
