IDZIN has profitable cash flow and they will become a wholly owned subsidiary of Metabolic Research (MTBR). In addition IDZIN has established relationships with decision makers at target market companies, and they have developed a marketing system that addresses Metabolic's primary target markets.

"This transaction will further accelerate our profitable entry into the market," said Dr. David Summers, Chairman and CEO. "The IDZIN customer base will propel sales of our line of dynamic state-of-the-art, natural, bio-identical, pharmaceutical-grade products.

On May 16 Metabolic Research (MTBR) acquired principal assets relating to metabolically engineered drug development, formulas, prototypes, packaging design and marketing rights from Partners in Science Holdings, Inc. The acquisition was completed through an "all stock" transaction utilizing restricted common shares of the Company.

Metabolic Research plans to utilize this technology to further its research and development of a new form of natural anti-inflammatory and analgesic products, both pharmaceuticals and nutraceuticals, for the treatment of arthritis and other inflammatory diseases.

Included in the purchase are 15 product formulations, branding for four trademarks/trade names, six provisional patent applications, two technologies ready for patent filing, three contract executives, and one marketing contract, all of which should enable MTBR to enter the market during the current quarter.

"This transaction should accelerate Metabolic Research's path to profitability. We are a fully reporting OTC company with a complete line of dynamic state-of-the-art products tailored to a dramatically growing demand for natural, bio-identical, pharmaceutical grade products.

This acquisition should prove to be the catalyst we need to quickly move from the R&D phase into one where we realize increasing revenues and profits, thus building long-term equity for our shareholders," says Dr. David Summers, D.Sc., Ph.D., Chief Executive Officer of Metabolic Research, Inc.

About Metabolic Research, Inc.:

Changing the way drugs are grown, Metabolic Research (MTBR) is a biotechnology company developing a new form of pharmaceutical grade non-synthetic pharmaceuticals aimed to safely and effectively treat arthritis, heart disease and metabolic and inflammatory diseases. MRI's proprietary process is based on "growing" drugs by using natural metabolic processes of plants or fungus rather than chemical synthesis used by traditional pharmaceutical companies.
Although the company plans to use the Agaricus blazei Murril mushroom, this process is compatible to any fungal species. The company's research in metabolic pharmaceuticals is in its initial phases, and preliminary research suggests this process could be used to develop safe and highly effective naturally produced pharmaceutical-grade anti-inflammatory, anti-infective and anti-viral substances to fight a broad range of diseases.

Metabolic Research, Inc. has recently acquired a license for two provisional patents "Composition and Method of Producing Endogenous Therapeutic Anti-Inflammatory Eiconasids and their Metabolites by Exogenous or Oral Means," and "Method and Process for Producing Anti-inflammatory Products from Fungi."

MRI's short-term game plan calls for using these patents to develop a natural drug to effectively treat arthritis.

MRI has just teamed up in a strategic alliance, one of the goals of which is to effectively develop a natural drug for cancer treatment.
