Custom & OEM

Your molecule,
our process.

When the catalog is not enough, we develop to your specification: sequence support, modifications, scale-up, and packaging under your own brand.

01

Peptide synthesis

Feasibility from 5 mg, scale-up to multi-gram batches, with HPLC purity agreed before production.

02

Modifications

Acetylation, amidation, biotinylation, fluorescent labelling and salt-form conversion.

03

Fermentation development

Strain and process optimisation to replace chemical routes or improve an existing profile.

04

OEM & private label

Filling, labelling and cartoning to your artwork and market requirements.

Discuss a custom project

Packaging & documents

Packed for the
journey, not just the shelf.

Packaging is selected around the material: light, moisture and oxygen sensitivity first, then your handling and inventory requirements. Every shipment leaves with a packing list and a document set your customs broker can work with.

  • Amber glass vials with tamper-evident caps
  • Aluminium foil bags, nitrogen-flushed on request
  • Fibre drums with food-grade inner liners
  • Batch-specific COA, MSDS and specification sheet
  • Custom artwork, labelling and cartoning
