02 / Verification

Two methods, every lot, before anything ships.

Identity is confirmed by mass spectrometry against theoretical molecular weight. Purity is quantified by reverse-phase HPLC. Both reports attach to the lot number printed on your vial.

Method 01

Reverse-phase HPLC

C18, 220 nm, gradient elution

Peak area quantifies purity against the principal component. The measured value is printed on the certificate. Never rounded up, never inferred from a supplier label.

Method 02

Mass spectrometry

ESI-MS, positive mode

Observed mass is compared to the theoretical molecular weight for the sequence. A lot only ships when observed and theoretical agree within tolerance.

Method 03

Lot traceability

Vial label resolves to certificate

Each vial carries a lot number that resolves to a single certificate in the public library. Nothing is pooled, relabelled or re-lotted after testing.

03 / Documentation

Recent certificates of analysis

The most recent lots released, with their assay reports.

What researchers say

Feedback on dispatch, packaging and documentation.

Verified Buyer

Ordered Friday, tracking number Monday morning. The lot printed on the vial matched the certificate in the library exactly, which is the only reason there was a second order.

M. Chen 2026-07-14

Packaging was genuinely discreet, no branding anywhere on the outer box. Ice packs were still cold on arrival in July.

R. Okonkwo 2026-07-02
Verified Buyer

The certificate library is the difference. Being able to check a lot before buying rather than after is not something the other suppliers offer.

A. Lindqvist 2026-06-27
Verified Buyer

One vial arrived with a cracked seal. Photographed it, emailed the reference, replacement shipped the next day without an argument.

J. Tremblay 2026-06-19

Documentation is more complete than my last two suppliers combined. Conditions printed on the certificate, not just a number on its own.

S. Patel 2026-06-08

Slower at checkout than a card because of the e-Transfer step, but the payment was matched and confirmed within a few hours.
