PP · Ref. 2026.04 · Research Use Only

Reference-grade peptides, measured in decimals — not promises.

Every compound we release is synthesized, purified, and independently verified. Certificates of Analysis travel with every vial. Nothing is shipped until the chromatogram says so.

Built on four non-negotiables.

Our release standard is what gets a vial onto the fulfillment line. Everything below happens before a barcode is printed.

01 · Identity

Mass spectrometry confirms molecular weight against the theoretical target. The m/z signature is attached to every lot record before the vial leaves QC.

Identity confirmed by MS
02 · Purity

Reverse-phase HPLC at 214 nm. We publish the chromatogram. If a peak falls below our threshold, the lot is rejected — not discounted.

≥ 98% minimum release
03 · Documentation

Each order arrives with a Certificate of Analysis, lot number, synthesis date, and storage guidance. Nothing is implied. Everything is written.

COA on every shipment
04 · Consistency

We synthesize in controlled batches and archive a retention sample from every lot. Repeat orders draw from the same reference data — not a rolling average.

Lot-to-lot traceability
Documentation · COA

A Certificate of Analysis with every vial.

Every release comes with an individually-numbered COA documenting identity (MS), purity (HPLC), appearance, lot, and retention sample reference. Lookup is available by lot number at any time.

Why Precision

The quiet competence of a lab that ships.

We are not a storefront that repackages. We operate a closed fulfillment line that handles synthesis verification, cold-chain storage, and shipping under a single chain of custody — so the reference data you order is the reference data you receive.

Read our methodology →
  • 01
    Retained-sample archive
    Every lot is archived for reference. If a question arises six months later, the physical sample still exists.
  • 02
    Cold-chain fulfillment
    Thermally-stabilized packaging. Tracked transit. Lyophilized powder handled below handling-threshold until delivery.
  • 03
    Transparent rejection rate
    We publish our internal rejection rate each quarter. A lot that misses spec is destroyed, not re-graded.
  • 04
    Research professional support
    Direct access to QC staff by ticket. Lookup by lot. Documentation reissued on request.

Common questions.

Short, direct answers. If you need something more specific, our lab support desk responds within one business day.

What does "research use only" mean? +
Our products are intended strictly for in-vitro laboratory research conducted by qualified professionals. They are not drugs, supplements, cosmetics, or food. They are not intended for use in or on humans or animals, and we make no health, treatment, or therapeutic claims.
Can I see the Certificate of Analysis before I order? +
Yes. Each product page links directly to the current lot's COA. You can also access the COA for any lot on our website at any time using our Lot ID lookup portal.
How should I store peptide powder on arrival? +
Lyophilized powder is shipped shelf-stable for transit. Long-term storage is recommended below –20 °C in a dark, dry environment. Specific guidance is printed on every COA.
What is your release purity threshold? +
Our minimum release specification is ≥ 98% by HPLC at 214 nm. The actual purity for your lot is always published on the COA — it is typically higher.
Do you ship internationally? +
We currently ship within the United States. International shipping is evaluated on request. Customs documentation for research materials is prepared on a per-order basis.
