Pharmaceutical-grade peptides, engineered in the United States.
Superior Amino Compounds is a research peptide supplier focused on a single, narrow promise: every vial we ship is greater than 99% pure, identity-verified by mass spectrometry, and accompanied by a lot-specific Certificate of Analysis on request.
Synthesis
We work with US-based contract synthesis partners that operate under cGMP-aligned standards. Every active sequence is verified by RP-HPLC and mass spectrometry against theoretical molecular weight before fill.
Verification
Every lot is independently verified by an accredited third-party laboratory. We do not release to inventory until the third-party COA is received, signed, and archived.
Fulfillment
Lyophilized vials are filled, sealed, and packaged in climate-controlled rooms. Shipments use insulated, discreet packaging optimized for cold-chain integrity during transit.
The standard we ship to.
The research peptide market has a quality problem. Material sold as "research grade" frequently fails third-party verification — purity claims that don't match independent HPLC, identity mismatches, contaminated lots that can compromise downstream assays.
We exist because researchers depend on consistent material. A peptide that fails identity verification doesn't just waste a few vials — it invalidates weeks of cell culture, animal studies, or comparative pharmacology work.
Our quality commitment is straightforward: third-party HPLC purity greater than 99%, mass-spec identity verification, and LAL endotoxin testing — on every lot, with the COA available on request.
