Krause Analytical vs Gold Standard Analytics
Krause Analytical is a small, minority-owned Austin contract lab led by Mark Krause, a chemist with over 45 years of experience. Peptides are one of many lines alongside corn and grain, synthetic colors, BPA/BPS, import detention, cannabis and expert testimony. It runs HPLC-UV and HPLC-MS for purity, potency and identity, with endotoxin, metals and residual solvents available, and asks clients to submit a contact form for pricing. Gold Standard Analytics is a peptide-first laboratory in Houston with every price, method and instrument published and a two-minute online order.
