GCP Labs

GCP Laboratories is a private, commercial-stage contract development and manufacturing organization (CDMO) focused on generic OTC liquid drugs, with antacids as its core product line. Founded in 2018 (though operating a facility with a history dating to 2010), the company leverages a 132,000 sq. ft. vertically integrated plant in Mississippi to produce active pharmaceutical ingredients (API) and finished doses for private label clients. Its business model is built on economies of scale, US-based manufacturing assurance, and full-service capabilities from formulation to label design for retail chains.

Vertically integrated manufacturing platform for liquid and solid dose generic OTC pharmaceuticals, featuring in-house API production (e.g., magnesium hydroxide), formulation, high-volume packaging lines, full analytical testing, and custom label/packaging design services.

GCP competes in the CDMO space for OTC generics, particularly against other manufacturers specializing in liquid dosage forms. Its primary differentiation is its vertical integration (including API production) and emphasis on US-based quality and supply chain reliability, positioning it against both larger diversified CDMOs and lower-cost offshore producers.
