Resources to support your business


We manufacture amino acids to the highest standards of purity and quality. Which means we’re registered by, compliant with or certified by all the appropriate quality standards: cGMP, JP, USP, EP, DMF, JDMF, CEP, ICH, CFR and ISO. And that’s just for starters — because we maintain our own internal benchmarks that are, quite simply, second to none.

Milling & Blending

With our cGMP blending and pulverization services, we can produce amino acid blends to your exact specifications – so you can optimize production space, decrease analytical testing and improve inventory management.

  • Environmentally controlled Class 100,000 suite
  • Pilot scale 10-25 kgs batch size
  • Large scale 500-3500 kg batch size
  • Dediccility for amino acids
  • Custom and exclusive formulations and specifications
  • Custom packaging and labeling
  • Blending process development
  • Blend validation for quality control
  • Analytical support and technical service

Manufacturing & Packaging

Part of our job is to make your job as easy as possible. So once we create top-quality amino acids using our advanced fermentation manufacturing process and patented production technology, we make them available to you in the quantities you need.

In addition to Standard Bulk packaging — 20 kg, 25 kg and 50 kg sizes — we offer exactly the same pharmaceutical-grade amino acids in smaller 1 kg and 10 kg polyvinyl pails for R&D, product and process development and clinical trials.
