McGuff Outsourcing Solutions' Company History

McGuff Outsourcing Solutions, Inc. (MOS) captures 20+ years of compounding experience from its predecessor, McGuff Compounding Pharmacy Services (MCPS). At MCPS, we provided physicians and patients with quality pharmaceuticals including over 1,000 unique sterile and non-sterile products. MCPS produced over six million vials of sterile injections with the quality and efficacy demanded by its customers.

With the ever-changing regulatory environment, MCPS provided the opportunity for McGuff to build on its legacy and transform into McGuff Outsourcing Solutions, Inc., a 503B registered outsourcing facility. MOS, following current Good Manufacturing Practice (cGMP) regulations, will provide higher quality compounded drugs, faster and more consistent distribution of drugs to physicians, and have the potential to add new product lines to assist physicians in their quest to help patients.

Our motto remains, “To retain our uncompromising passion for quality pharmaceuticals and customer satisfaction".

As an outsourcing facility, McGuff Outsourcing Solutions, Inc. (MOS) meets federal 503B while maintaining the ability to develop new drugs for the market. Our focus is on providing high-quality raw materials, cGMP quality processes, industry-leading customer service and fast shipping.
