Research-grade peptides

Purity you can
put on record.

Every lot is mass-verified, HPLC-tested past 99%, and shipped cold with its own certificate. Built for the bench, not the hype.

Why the bench trusts us

Three things we never skip.

01 — IDENTITY

Mass-verified

Every batch is confirmed by mass spectrometry before it ever gets a label. You get the exact compound on the vial, nothing else.

02 — PURITY

HPLC past 99%

High-performance liquid chromatography on each lot, with the chromatogram included. We publish the number, not a promise.

03 — COLD CHAIN

Shipped cold

Lyophilized, sealed, and dispatched with cold packs so the compound that leaves the freezer is the compound that reaches your bench.

Tested twice, shipped once

The certificate is the product.

Anyone can print a purity claim on a bag. We attach the actual chromatogram and mass-spec trace for the specific lot in your hands, tied to a number you can scan.

No house averages, no representative samples. The paper matches the powder, every time.

How we test
Storage that respects chemistry

Frozen until it's yours.

Peptides degrade when they sit warm. Ours stay at −20°C from synthesis through dispatch, then travel insulated so they arrive intact, not half-spent.

Each vial ships with reconstitution and storage notes so the integrity you paid for survives your first pipette.

What researchers say

Trusted at the bench.

COA matched the vial

Ran my own HPLC check against the certificate they shipped and the numbers lined up to the decimal. That's the whole reason I switched suppliers.

Cold pack still frozen

Box arrived two days out and the gel pack was solid. Vials sealed, labeled, lot numbers legible. Packaging is clearly built for the compound, not just the shipper.

JTJ. TanakaVerified

Fourth reorder, same quality

Consistency batch to batch is what matters for my work. Four orders in and the purity has held every time. Support answered a documentation question same day.
