Our Story

The founders of PinPoint Testing are experts in detecting and studying new psychoactive substances (NPS), or “designer drugs.” Dr. Jeffery Moran and Dr. Greg Endres, along with UAMS researchers, played a crucial role in understanding the dangers of these substances, such as synthetic cannabinoids and designer benzodiazepines. Their experience during the designer drug epidemic led them to recognize the need for better-equipped laboratories and efficient processes to address emerging threats to public health.

PinPoint Testing, led by seasoned leaders in toxicology and public health, guides labs on adopting lean principles and best practices to enhance efficiency. This approach helps labs update processes swiftly, ensuring they can adapt to evolving demands. With expertise in analytical chemistry and various small molecules, PinPoint specializes in detecting molecules in biological samples, the screening and confirmation of small molecules, environmental hazards, food toxins, and industrial hygiene.

PinPoint, certified under 150-17025 & CLIA, stays at the forefront of testing practices by continually researching and developing new methods and technologies. Alongside consulting services, PinPoint offers off-the-shelf and fully customizable ToxBox® products that specialize in workflow efficiencies, as well as reference laboratory services and expert testimony.

PinPoint Testing Credentials and Certifications

Dr. Endres was qualified in several fields as an expert witness: identification; classification; manufacture; and pharmacology of synthetic cannabinoids. He provided testimony as to all four aspects of synthetic cannabinoids, but most importantly made a compelling case that XLR-11 was in fact a cannabinoid receptor agonist and therefore a synthetic cannabinoid and Schedule 1 controlled substance. Thanks to this testimony, we were able to secure convictions against both defendants for Criminal Enterprise; Possession with Intent to Deliver a Schedule 1 Controlled Substance; Manufacture of a Schedule 1 Controlled Substance; Delivery of a Schedule 1 Controlled Substance; Possession of a Schedule 1 Controlled Substance; and Maintaining a Drug Store/House. Therefore, I would highly recommend him for any future use in his capacity as an expert witness in these fields.

I would certainly continue to endorse Dr. Endres as an expert in this field. I have always been grateful for his assistance in our case as I know we could not have put everything together and prosecuted our case with success without his testimony. I was fortunate to find someone with his background, and qualifications, who was willing to step outside his daily mold and accept such a task.

We have not had any K2 issues since the defendant was successfully removed from our community.”
