Peptide Testing Services FAQ

ACS Peptide Testing Labs offers HPLC purity testing, third-party verification, molecular analysis (mass spectrometry), contaminant screening (ICP-MS heavy metal screening, GC-MS residual solvent analysis, and quantitative LAL endotoxin testing), stability studies (accelerated and long-term), and custom analysis with tailored protocols.

For verifying a supplier's claims, start with our Third-Party Verification package. For research-grade quality assurance, choose Purity Testing. If you need to confirm peptide identity and sequence, select Molecular Analysis. For safety screening, use Contaminant Testing. Our team can also recommend the best combination during a free consultation.

Yes, we offer discounted multi-test packages. Our most popular bundle combines purity testing (HPLC) with identity confirmation (mass spectrometry) for complete peptide characterization. Custom bundles are available. Request a quote to discuss your specific needs.

Standard turnaround is 9-11 business days for most services. Stability studies have longer timelines depending on study design (3-36 months). We provide estimated completion dates when you submit your sample.

Absolutely. We regularly handle batch submissions of 5-50+ samples. Volume discounts are available for large orders, and we provide a single comprehensive report covering all samples. Contact us for bulk pricing.

Yes, GLP-1 receptor agonist peptides are among our most frequently tested compounds. We provide purity testing, identity confirmation, and contaminant screening (heavy metals and residual solvents) for Semaglutide, Tirzepatide, Retatrutide, and other GLP-1 peptides with validated methods optimized for these specific sequences.

Pricing depends on the type of analysis and number of samples. Single-peptide purity testing starts at competitive rates, with volume discounts for 5+ samples. Comprehensive panels combining purity, identity, and contaminant testing are available at bundled pricing. Request a free quote for an exact estimate.

Yes, every completed test includes a detailed Certificate of Analysis. Our COAs include raw data, methodology descriptions, instrument calibration records, and clear pass/fail criteria against USP or client-specified standards. Digital COAs are delivered via email within 24 hours of test completion.

Absolutely. We work with compounding pharmacies nationwide, providing USP-compliant purity testing, identity verification, heavy metal screening, and sterility-related testing. Our reports are formatted to support pharmacy board compliance documentation and 503A/503B requirements.

Ship samples via overnight courier (FedEx, UPS) with cold packs to maintain stability. We accept samples from all 50 states. Upon receiving your quote confirmation, we'll send detailed shipping instructions including our lab address, labeling requirements, and chain-of-custody forms.
