Purity standard

every lot tested. every result published.

We do not average results across batches or reuse historical assays. Each lot is sent to an independent laboratory for HPLC purity and mass-spectrometry identity confirmation, and the signed certificate is posted to the product page with its lot number before the first vial ships.

Process

from synthesis to your bench

Synthesis

Solid-phase synthesis at cGMP-audited partner facilities with documented reagent traceability.

Third-party assay

Independent HPLC purity and mass-spec identity confirmation on every single lot, never batch-averaged.

Cold chain

Lyophilized, argon-flushed, and held at -20°C until your order is packed with cold packs.

Documentation

Batch-matched COA, lot number, and handling sheet delivered with your shipment.

Loved by labs

researchers keep reordering.

“The COA arrives before the vial does. That alone put Pepdoll ahead of every supplier we had used.”

Dr. R. AlvarezDermal research lab, Austin

“Cold chain held perfectly and the lot numbers matched the published assay to the decimal.”

M. ChenPrincipal investigator

“Reordering takes a minute and dispatch is same day. Our bench never waits.”
