About Us


Our medical researchers and future founders began studying the NLS Diagnostic Industry in 2010. Like so many unfortunate others around the world, even they fell victim to the wily salesmanship of one of the numerous counterfeit companies which have historically plagued the industry. After exhaustive pain-staking research and corporate due diligence it was determined that the only legal manufacturer of Nonlinear Diagnostic Systems (“NLS”) in the world was the Institute of Practical Psychophysics (IPP) based in Omsk, Russia. The IPP is the only NLS company that has patents, trademarks, governmental medical device registrations and international software copyrights. Simply put, if you see a system with graphics similar to Metatron’s and using the same Fleindler color coded scale, they are without a doubt counterfeit units and should be reported to NPD and your appropriate governmental medical device regulatory agency.

Why are black market counterfeits such a global industry problem?

Our market analysis concluded that the following factors play a key role:

  • IPP is based in central Siberia, where transportation and communication with the outside world has been limited
  • Lack of English support
  • Unfamiliar with western business practices/customer service
  • Weak Russian legal framework post USSR
  • Lack of legal representation abroad
  • Uniqueness of technology

Our research led to partnership with the IPP and NPD International was founded in 2012 to address these concerns. Moreover, in January 2016, NPD received power of attorney to better assist the IPP in bringing counterfeit manufacturers to justice.

We are currently the #1 company in the English speaking world, in terms of NLS sales and Medical Training!

Dedicated to Medical Research
Since our formation we have conducted a number of clinical trials in house as well as done joint projects with USA non-profits. To date, no NPD employee has accepted a salary and we have operated as a non-profit with almost all revenue allocated to research.  For further information on our major clinical studies click here.

Corporate Structure
Our company is based in Hong Kong in order to take advantage of HSBC Hong Kong’s multicurrency commercial accounts. This allows us to reduce international currency exchange transaction costs and pass these savings to our global customers. Moreover, Hong Kong has been a longstanding leader in international business and offers the best combination of tax rates, access to capital markets and an internationally recognized legal system.

Most notably we operate almost solely through outsourcing and operating costs are paid as a percentage of medical device sales. This assures our customers that we will be able to support their Metatron system indefinitely as it is basically impossible for our company to become insolvent based on our dynamic corporate structure and dedicated volunteers.
