Synthesis You Can Trust
Every peptide begins as a carefully designed sequence and ends as a fully characterized, analytically verified compound. Our solid-phase peptide synthesis (SPPS) workflow delivers consistent, reproducible results at every scale.
Sequence Design & Planning
Our chemists review every sequence for synthesis feasibility, solubility, and stability before a single resin bead is loaded.
Solid-Phase Synthesis (SPPS)
Fmoc-SPPS on automated synthesizers with coupling efficiency monitoring at every residue addition cycle.
Purification by HPLC
Reverse-phase preparative HPLC removes truncated sequences and impurities. Final product meets ≥99% purity unless otherwise specified.
Mass Spec & Analytics
ESI-MS confirmation of molecular weight. Every lot ships with a Certificate of Analysis including HPLC chromatogram and mass spectrum.
Every Vial Verified
We don't ship anything we wouldn't stake our reputation on. Full analytical documentation, every order.
HPLC Purity Testing
High-performance liquid chromatography on every batch. Purity profiles are included in the COA shipped with your order.
Mass Spectrometry
ESI-MS molecular weight confirmation verifies the exact peptide you ordered was correctly synthesized and delivered.
Certificate of Analysis
Every shipment includes a detailed COA with lot number, sequence, purity percentage, molecular weight, and storage conditions.
Cold-Chain Shipping
Lyophilized peptides ship in insulated packaging with desiccant. Express options available to ensure product integrity on arrival.
US-Based Synthesis
All peptides are synthesized and characterized in our US laboratory — never outsourced. Domestic quality, domestic accountability.
Batch Traceability
Unique lot numbers on every vial. Full synthesis records retained for traceability — we can trace every batch back to raw materials.
Why The Pep Smart?
The Pep Smart was founded by a team of peptide chemists and research scientists who were frustrated by inconsistent quality and opaque documentation in the peptide supply industry. We built the company we wished existed when we were doing our own research.
Our mission is simple: deliver the most analytically rigorous research peptides available, with full transparency at every step — from synthesis to your lab bench.
We confirm every molecular weight before shipment. If it's not right, we re-synthesize.
No hidden processes. Every COA shows the actual chromatogram and mass spectrum — not a generic certificate.
Our team has published primary research. We understand what data-quality means for your results.
Trusted by Scientists
"The HPLC traces on every COA are the real deal — sharp peaks, no ghost impurities. Finally a supplier who shows you actual data, not stock images of a chromatogram."
"Ordered a custom 32-mer with two non-natural amino acids. Delivered in 18 days, MW confirmed perfect. I've used four other suppliers and none come close to this turnaround and quality."
"We run a CRO and need consistent lot-to-lot quality. The Pep Smart is the only supplier where we don't need to re-qualify every new batch. Reproducibility is remarkable."
