01
Synthesis under cGMP-aligned conditions
Peptides are produced by solid-phase synthesis in facilities operating to cGMP-aligned process controls, with documented batch records for every run.
The Standard
Every lot is tested by someone who does not work for us.
Research is only as reliable as the material it runs on. A vial with no COA is an unknown variable in your data. Here is exactly what happens between synthesis and the box on your bench.

02
HPLC purity assay
An independent US laboratory runs reverse-phase HPLC on each lot. We release only material assaying at ≥99% purity — anything below the threshold is rejected outright.
03
Mass spectrometry identity confirmation
Mass spec confirms the measured molecular weight matches the target sequence, ruling out truncated or mis-sequenced product that a purity number alone would not catch.
04
Endotoxin and sterility screening
Lyophilized material is screened for bacterial endotoxin so laboratory results are not confounded by contamination.
05
Lot-matched Certificate of Analysis
The COA shipped with your vial corresponds to the exact lot number printed on the label — not a representative sample from an earlier run.
06
Cold-chain fulfillment from the USA
Vials ship lyophilized and temperature-controlled from a US facility, typically within one business day of order confirmation.
Reading a COA before you buy
Check three things: the lot number matches your vial, the purity figure comes from HPLC rather than a manufacturer estimate, and the mass-spec result confirms the expected molecular weight. If a supplier cannot produce all three, the material is unverified.
