Every vial ships with a third-party certificate of analysis — HPLC purity, mass-spec identity, and batch traceability. No mystery powders. No vague claims. Just the data.
GEPPPGKPADDAGLVFilter by research area or search by name or sequence. Every listing shows molecular weight, single-letter sequence, and verified purity up front.
Four checkpoints stand between synthesis and your bench. Each one is documented and traceable to the batch on your vial.
High-performance liquid chromatography quantifies purity on every batch, with a hard floor of 99%. The trace ships with the vial.
Mass spectrometry confirms the compound is exactly what the label says — molecular weight matched against spec, every time.
LAL testing keeps endotoxin levels documented and low, so your research model starts from a known, clean baseline.
Look up the batch ID to pull the matching certificate of analysis — synthesis date, test methods, and results, archived for two years.
Enter the batch ID printed on your vial label to pull its full test record — HPLC purity, mass-spec identity, endotoxin, and dates. No login required.
Solid-phase peptide synthesis in a US facility, built to your batch spec. Crude product is cleaved, purified, and lyophilized into a stable powder.
An outside lab runs HPLC, mass spec, and endotoxin screening. Nothing leaves inventory until the certificate clears the 99% purity floor.
Vials ship discreetly with cold packs and the matching COA. Tracking and batch records land in your inbox the moment it goes out.
Verified buyers across academic, biotech, and independent research settings.
The COA matched the vial down to the batch number. First supplier where the chromatogram wasn't an afterthought buried three pages deep.
Cold-chain packaging arrived intact in July heat. Reconstitution was clean, no haze. The consistency batch to batch is what keeps me ordering.
I order for a procurement team and documentation is everything. Apex is the only vendor whose paperwork I don't have to chase down.
Restock alerts, fresh certificates, and research-area notes. No noise — just what shipped and what passed.
Apex supplies peptides strictly for laboratory research.
