Fast, Reliable Analytical Testing for Peptides, Supplements & Biotech
Advanced HPLC/MS instrumentation delivers precise Certificates of Analysis in days, not weeks. Trusted by researchers and product companies across the United States.
Trusted Analytical Testing Laboratory
Redstone Analytics is an independent analytical testing lab specializing in fast, accurate characterization of synthetic peptides and research compounds. With labs in Kenilworth, NJ and Peekskill, NY (mail-in only, no walk-ins), we deliver clear, trustworthy Certificates of Analysis using advanced HPLC-MS systems.
Our mission is simple: give manufacturers and suppliers independent, defensible data they can stand behind. Whether you need purity verification, identity confirmation, or full quantitative analysis, we provide rapid turnaround and transparent reporting that builds real credibility with your customers.
Our Testing Services
Each test includes a detailed Certificate of Analysis with raw data and method documentation.
HPLC/MS Purity Testing
High-precision purity analysis for research peptides and compounds with detailed COAs. Ideal for vendors, researchers, and e-commerce compliance.
DetailsChemical Identity Confirmation
Definitive structural confirmation using MS and spectral matching. Verify your compound matches its intended structure with certificate-ready results.
DetailsContent / Quantity (Beer-Lambert)
Accurate quantitation for active ingredients and formulations. Validated methods with demonstrated precision and linearity.
DetailsGLP-1 Blind Identification — $275
Don't know what's in the vial? Send two vials and we identify which GLP-1 peptide it is (semaglutide, tirzepatide, retatrutide and other GLP-1 class compounds) by retention time and UV spectrum against our reference panel, then report identity, purity and content. 5-day turnaround. Two vials required.
DetailsEndotoxin Testing
Kinetic turbidimetric LAL assay for bacterial endotoxin detection. Meet USP <85> requirements with sensitivity down to 0.005 EU/mL.
DetailsHeavy Metals Screening (ICP-MS)
Elemental analysis for lead, cadmium, mercury, nickel, iron, and cobalt. Supports quality control, vendor qualification, and product confidence.
DetailsCannabinoid Potency Testing
HPLC-based cannabinoid profiling and potency testing for hemp-derived products.
DetailsTransparent Pricing
Straightforward pricing with no hidden fees. Every test includes a detailed Certificate of Analysis with raw data. Volume discounts available for 10+ samples per month.
