LOS ANGELES and MIDDLESEX, N.J., Jan. 14, 2026 (GLOBE NEWSWIRE) — Anresco NJ Labs has expanded its laboratory network with aligned facilities on both the East and West Coasts, strengthening its ability to provide consistent analytical chemistry and microbiology testing nationwide. With laboratories in Middlesex, N.J., and Los Angeles, clients can submit samples to the nearest location while receiving standardized methods, quality systems, and reporting across both sites.
The two laboratories operate independently while collaborating through shared scientific protocols and technical expertise, supporting companies that work with suppliers, manufacturers, and partners in multiple regions. Anresco NJ Labs East in Middlesex is led by CEO Rajul Vyas, and Anresco NJ Labs West in Los Angeles is led by Zachary Eisenberg. The bi-coastal structure is intended to support faster, more consistent compliance testing and help reduce the risk of delays or product delistings, particularly on retail platforms such as Amazon, where testing requirements vary widely by product type, formulation and claim.
“Amazon compliance is not one-size-fits-all. The way testing is performed matters far more than the simple act of testing itself,” said Vyas. “By unifying expertise across both coasts, we can apply specific methods tailored to the product to maintain reproducible results for each batch.”
Both laboratories will offer comprehensive chemistry, microbiology and stability testing, including identity and ingredient verification, potency testing, purity and contaminant screening, and stability assessments to ensure long-term product integrity. A key focus will be low-limit heavy metals testing, particularly for baby food, infant formula and other sensitive products where detection limits, sample preparation and matrix complexity present significant challenges for many laboratories.
“Companies are under growing pressure to meet extremely low contaminant thresholds, especially for infant and sensitive products,” said Eisenberg. “Our approach emphasizes how testing is done, using robust digestion techniques, high-sensitivity instrumentation and scientifically validated methods. This makes the data traceable, repeatable and defensible.”
Anresco NJ Labs serves dietary supplements, foods, personal care, chemicals, hemp, cannabis and pharmaceutical industries. With multiple laboratories strategically located on both coasts, the collaboration provides nationwide access, shared logistics and faster turnaround times while maintaining independent, compliant and trusted testing standards.
Anresco Laboratories, headquartered in San Francisco, and NJ Labs, based in New Brunswick, N.J., operate as separate entities while sharing resources, scientific methods, research and intellectual property under the Anresco NJ Labs. Both Anresco Laboratories and NJ Labs are active members of ACIL (American Council of Independent Laboratories), a national association focused on strengthening independent testing laboratories across regulated industries. Eisenberg serves on the ACIL Board and is the co-chair of the Cannabis Sciences Section, working alongside peer laboratories, regulators, and policymakers to advance science-based testing standards that protect public health. NJ Labs CEO, Sandra Lee participates in the ACIL Dietary Supplements Working Group and FDA-related technical committees, contributing to ongoing dialogue between regulators and the laboratory community. Collectively, ACIL encourages manufacturers and brand owners to take greater responsibility for product quality, drawing on expertise spanning pharmaceutical, dietary supplement, food, cannabis, and other regulated industries.
The expanded network of Anresco NJ Labs enables brands and manufacturers to move beyond simply checking a compliance box, offering reliable data that supports regulatory readiness, protects consumers and helps companies confidently remain listed and competitive in complex marketplaces.
