At PEPSTAR, we believe research is only as good as the materials behind it. That’s why every compound we ship is held to a single uncompromising standard: verified 99%+ purity, every batch, every vial.
Our standard
Every product in our catalog is independently analyzed by third-party laboratories using High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (MS). We publish certificates of analysis so you never have to take purity on faith — you can verify it.
- Independently tested — HPLC & MS verified for identity and purity.
- Properly handled — lyophilized, sealed, and stored under controlled conditions.
- Clearly labeled — lot numbers, dosing, and storage guidance on every vial.
- USA fulfillment — fast, discreet, domestic shipping.
Fast, discreet, reliable
Orders placed before 3PM EST ship the same day. We package with temperature in mind and ship discreetly, with free shipping on orders over $200.
