Here's exactly how a compound goes from synthesis to your bench — and how you can verify each step yourself.
Mass spectrometry confirms the compound is what the label says — exact molecular mass, no ambiguity.
Reverse-phase HPLC quantifies purity against a 99% minimum spec. The chromatogram is attached to the COA.
A third-party analytical lab repeats identity and purity. Their report — not ours alone — backs the certificate.
Passing lots are lyophilized, sealed, and logged into the public COA library, traceable from vial to batch.
A high-purity peptide resolves as a single dominant peak. Shoulders and secondary peaks are impurities. Our acceptance line is 99% of total area under the main peak.

Store lyophilized powder at -20°C, protected from light. In powder form, peptides are stable long-term.
Add bacteriostatic water down the vial wall, swirl gently, and let dissolve fully. Shaking can degrade fragile sequences.
Store reconstituted peptide at 2–8°C and limit freeze-thaw cycles to preserve activity.
