About Krause Analytical

Krause Analytical is a US-based contract analytical laboratory providing peptide purity and identity testing alongside grain, pesticide, and pharmaceutical analysis, with a documented specialization in serving compounding pharmacies handling GLP-1 formulations (Semaglutide, Tirzepatide, Retatrutide). The lab operates HPLC-UV, HPLC-MS, GC-MS, LC-MS, ICP, UV, and IR instrumentation in-house.

Krause offers Expert Witness Testimony as a standing service — meaning the lab regularly produces analytical work that meets evidentiary standards for legal proceedings, a service tier no other lab in the Peptigrity index publicly offers.

What sets Krause Analytical apart

  • ✓Expert Witness Testimony as a standing service. Krause publicly markets Expert Witness Testimony alongside its analytical work — the lab produces analytical reports that meet evidentiary standards for legal proceedings. No other lab in the Peptigrity index publicly offers this. Relevant for buyers in disputes, vendor lawsuits, or regulatory proceedings where lab results need to hold up in court.
  • ✓Compounding-pharmacy focus on GLP-1 peptides. The lab explicitly markets to compounding pharmacies needing GLP-1 formulation testing (Semaglutide, Tirzepatide, Retatrutide) — a buyer profile that requires methodological rigor consistent with pharmacy-grade quality controls.
  • ✓Documented accuracy on mislabeled samples. In community-documented early 2025 testing, Krause was one of five labs that correctly identified a mislabeled Peptide Sciences sample (Tirzepatide submitted as Retatrutide) that another major peptide lab initially mis-identified.
  • ✓Broad in-house instrumentation — HPLC-UV and HPLC-MS for peptides, GC-MS for residual solvents, ICP for heavy metals, plus UV and IR spectroscopy. Full analytical chemistry capability without subcontracting.
  • ✓Validated methods library — the lab markets "lots of validated methods," relevant for buyers wanting compendial method documentation alongside results.
Honest disclosures
  • Accreditation — see the note above.
  • Peptide testing is one segment of a multi-industry analytical portfolio that includes grain, pesticide, and pharmaceutical testing — not a peptide-only specialization. Compounding-pharmacy GLP-1 work is the explicitly marketed peptide service tier.
  • Pricing is not published on the homepage — quoted per submission, with the lab oriented toward commercial pharmacy and compounding clients.
