About Specgx LLC
Specgx LLC, doing business as Mallinckrodt Pharmaceuticals, a foreign-owned pharmaceutical manufacturer headquartered in Webster Groves, Missouri, supplies controlled substance medications and specialized pharmaceutical products to federal healthcare agencies exclusively as a prime contractor, competing full-and-open without set-aside designations. The company manufactures methadone formulations, hydrocodone-acetaminophen combinations, methylphenidate hydrochloride tablets, morphine immediate- and extended-release formulations, and oxycodone placebo tablets for federal pain management, substance abuse treatment, and law enforcement applications.
Specgx's customer base concentrates heavily within the Department of Veterans Affairs ecosystem, which accounts for the bulk of award count but a smaller share of potential value. The Veterans Integrated Service Network 5 has placed 22 awards (all firm-fixed-price delivery orders totaling $102 thousand in combined potential value) for methadone cherry liquid and methadone-tablet combinations under the VA's Pharmaceuticals and Drugs Federal Supply Schedule contract. The Defense Logistics Agency Troop Support Medical dominates the potential-value ranking, anchoring nine single-award indefinite delivery contracts valued at $109.4 million combined, awarded between September 2022 and November 2025 for morphine, hydrocodone-acetaminophen, methylphenidate immediate- and extended-release formulations, and atropine-diphenoxylate tablets. The Drug Enforcement Administration has placed four awards totaling $1 thousand for oxycodone placebo tablets used in reverse undercover operations and DEA laboratory reference materials. The National Acquisition Center awarded one $1.4 million indefinite delivery contract (later exercised to extend through May 2027) for atropine-diphenoxylate supply.
Specgx holds a $107.6 million Federal Supply Schedule contract with the Veterans Affairs, issued September 15, 2022 and running through September 14, 2027, under which VISN 5 has issued sixteen delivery orders since October 2022 for methadone products. Seven additional single-award indefinite delivery contracts with DLA and the National Acquisition Center, awarded between September 2022 and November 2025, carry combined ceilings of $48.8 million and establish Specgx as the national supply source for Schedule II and other controlled substance medications across the Department of Defense, Bureau of Prisons, Indian Health Service, and the VA prime vendor programs. Activity has declined from eight awards in 2022 to one award in 2026 year-to-date; however, the December 2024 and November 2025 indefinite delivery awards to DLA establish multi-year supply relationships extending through 2029 and 2030, providing contract stability despite lower annual award frequency. Specgx operates manufacturing facilities in Webster Groves and Hobart, New York. The vendor has no subcontract footprint and does not appear on any government-wide acquisition contracts or agency-wide multiple-award vehicles beyond the VA's Federal Supply Schedule.
