CONTRACT MANUFACTURING
Gemini Pharmaceuticals
Gemini Pharmaceuticals has produced tablets, capsules, and OTC pharmaceuticals from Commack, New York for over 30 years. The company produces 13 billion dosage units per year and packages over 150,000 bottles per shift. They report FDA registration, Health Canada site licensing, TGA (Australia) listing, and NSF International certification, though NSF could not be confirmed through NSF's public GMP directory as of March 2026. Gemini was the first manufacturer to earn RIBUS Certified Contract Manufacturer status for clean label products. They recently received approval for a $25 million expansion supported by Suffolk County IDA incentives. This expansion includes a new probiotic supplement facility at 81 Modular Avenue. Their 300,000 unit minimum order signals they serve mid-to-large brands, not startups. The ISO 17025 accredited in-house laboratory handles identity testing, potency analysis, and stability studies.
