About Us
Independent Laboratory Services Rooted in Integrity and Expertise
Phase 4 Services represents multiple independent analytical laboratories in the NorthEast specializing in chemical and microbiological analysis for regulatory compliance, product investigations, and legal cases. We serve manufacturers, regulators, private clients, and attorneys across Massachusetts, New York, Maine, and nationwide.
Our mission is simple: deliver clear, defensible results grounded in sound science.
What We Do
We provide supplement and pharmaceutical testing, food and beverage analysis, forensic laboratory services, and expert data review. Our work helps clients make informed decisions – whether to ensure product safety, verify questionable test results, or resolve a legal dispute. Every case we take is handled with strict attention to detail, chain-of-custody protocols, and scientific rigor.
Who We Work With
- Companies needing independent lab verification
- Regulatory consultants preparing for FDA or OSHA audits
- Clients facing product recalls, contamination concerns, or disputes with labs
- Attorneys seeking expert witness services or evidence testing
- Our clients rely on us when accuracy matters most.
Our Difference
Our clients rely on us when accuracy matters most. We are not part of a manufacturing or regulatory entity. Our independence means our results stand on their own: unbiased, transparent, and built to withstand scrutiny in court or regulatory review. Our lab is equipped with advanced instrumentation, including HPLC, GC-MS, LC-MS/MS, and microbiological platforms, operated by experienced scientists.
Where We Work
Based in Massachusetts, Maine, and New York, we work with clients across the Northeast and provide services nationwide. Whether you’re in New England or California, we can consult, receive, and process your samples quickly and securely.
