Certifications, standards & research-use FAQ

Every lot in the catalog is synthesized in audited facilities, assayed by an accredited third-party analytical laboratory, and released only with a Certificate of Analysis tied to its lot number. This page documents the certifications we hold our supply chain to, the release standards a lot must meet, and the questions researchers ask most often.

Laboratory certifications

ISO/IEC 17025 analytical partner

Purity and identity assays are performed by an accredited third-party analytical laboratory operating under ISO/IEC 17025 quality management. Raw chromatograms and spectra are retained with the lot record.

cGMP-audited synthesis facility

Solid-phase synthesis, purification and lyophilization take place in audited partner facilities following current good manufacturing practice for research-grade materials.

Lot traceability program

Every vial carries a lot number traceable to its synthesis batch, analytical panel and release date. Records are retained for a minimum of five years.

Low-endotoxin fill and release testing

Vials are filled in a controlled environment, sterile-filtered before lyophilization, and screened for endotoxin and bioburden prior to release.

Controlled cold-chain storage

Released inventory is held at −20 °C in monitored freezers with alarmed temperature logging, and shipped with cold packs and tracked delivery.

Research-use-only release policy

Material is released only against a research-use attestation. Nothing in the catalog is released for human or veterinary administration, resale for consumption, or clinical use.

Release standards

A lot is released to the catalog only when every line below conforms.

Peptide research-use FAQ

What does “research use only” actually mean?
Every compound in the catalog is supplied strictly for in-vitro laboratory research and development. Nothing is a drug, food, cosmetic or dietary supplement, and nothing is intended to diagnose, treat, cure or prevent any disease or condition in humans or animals. Human and veterinary administration is prohibited and voids all warranties.
Who is eligible to order?
Orders are accepted from qualified researchers, licensed laboratories, universities and commercial research organizations with the training and facilities to handle research compounds safely. Purchasers attest at entry that they are at least 21 years of age, and identification may be requested before an order is released.
How is purity determined, and what is the floor?
Purity is determined by reverse-phase HPLC against a 98.5% floor, with identity confirmed by mass spectrometry. Both results, plus water content and endotoxin screening, appear on the Certificate of Analysis for the specific lot you receive.
Where do I find the Certificate of Analysis for my lot?
Your order confirmation email links to a compliance pack page listing every lot in the order with its analytical panel, laboratory certifications and handling instructions. The same pack is downloadable as a PDF from the order status page in your account.
How should vials be stored and reconstituted?
Store unopened lyophilized vials at 2–8 °C for short term or −20 °C for long-term storage, protected from light. Let the vial reach room temperature before reconstitution, direct the diluent down the vial wall rather than shaking, then label the reconstituted vial with compound, concentration, lot and date and refrigerate it.
How long is reconstituted material usable?
Stability depends on the compound and the diluent. Use the window stated on the individual product page, keep reconstituted material refrigerated and protected from light, and avoid repeated freeze-thaw cycles.
Is testing an approval of safety?
No. Analytical testing establishes purity and identity for research purposes only. It does not make any product safe or approved for human or veterinary use, and no result should be read as a clinical claim.
How is waste handled?
Dispose of unused material, reconstituted solutions and sharps through your institution's chemical waste stream in accordance with local regulations. Never return research material to general refuse.
