Peptide API Supplier: Bulk Raw Material for Compounders and Manufacturers
How Star Distribution supplies bulk peptide API — green-list sourcing, per-shipment testing, documentation, and who qualifies to buy raw material.
What we supply
Every compound in the Star Distribution catalog is available as bulk raw API — the same material we fill in our own cleanrooms — supplied by the gram or kilogram with documentation for each shipment. It's sold to qualified commercial and research accounts: licensed compounding pharmacies, contract manufacturers, and research organizations with their own sterile capability and quality systems.
How the API is sourced and verified
- Sourced directly from green-list registered manufacturers under our own import logistics — no broker layer, no anonymous middle step.
- Tested for purity and assay on every shipment before it enters production, alongside residual solvent, endotoxin, and microbial testing.
- Full chain of custody from source to your receiving dock.
API vs. finished vials
Raw API only makes sense if you have a certified cleanroom, sterile fill capability, and a release process. If any of those is "not yet," finished lyophilized vials are the better business decision — same material, with the manufacturing and release testing already done. Many partners run both: API for one channel, vials for another. A fuller comparison.
How to request API
- Create a Partner Portal account (Pharmacy / compounder or Research brand).
- On the portal form, tick "Raw API" and list the compounds, quantities in grams or kilograms, purity specification, and intended use.
- We confirm availability, documentation, and pricing by email.
