Trusted Peptide Testing Labs

DEA Schedule III licensed analytical lab in the United States that tests peptides, SARMs, and small molecules. It runs HPLC with UV detection alongside mass spectrometry on Bruker QTOF and Thermo ion-trap instruments, and can validate methods under GLP when a study requires it. In early 2025 it correctly identified mislabeled peptide samples that another major lab had initially misread, the kind of independent cross-check that makes it a strong US-based second opinion.

Independent third-party lab established in 2020 that tests, but does not sell or endorse, peptides and research compounds. It verifies identity, purity, net content, sterility, bacterial endotoxin, heavy metals, and adulterants by HPLC and LC-MS, then issues per-batch certificates you confirm directly on Titreon by QR code or certificate key, so a vendor cannot tamper with the result. Research use only.

ISO/IEC 17025:2017 accredited laboratory in the United States that tests a wide range of research peptides for content and purity. It runs HPLC-UV validated to USP methods with reported precision to 0.01%, confirms identity by mass spectrometry, screens heavy metals by ICP-MS, and checks endotoxin per USP standards, then issues a COA with detailed reports. The formal accreditation makes it a strong choice when you want a credentialed, audit-grade result.

US-based analytical lab with a strong reputation in the research community for careful, GLP-style methodology. It handles HPLC purity, identity confirmation, quantification, and small-molecule analysis, and accepts mailed samples internationally. A solid pick when you are verifying a higher-value order and want a second, US-based opinion alongside a Janoshik result.

US laboratory with a broader, safety-focused scope than purity-only labs. Alongside peptide purity and research-compound analysis, it runs endotoxin and sterility testing, which matters when your concern is injection safety rather than identity alone. Reports are more comprehensive than a basic purity test, at a correspondingly higher cost and longer turnaround.

US-based analytical lab with a dedicated research-peptide program built around standardized QC panels covering purity, endotoxin, sterility, and heavy metals. You can run a full panel or order a-la-carte and pay only for the analyses you need, and a client portal handles sample submission, tracking, and verified results. Its published 3 to 5 business-day turnaround is among the faster options for a multi-assay panel.
