Quality & Testing

Proof, Not Promises

Every batch undergoes six-point full-panel analytical verification by independent U.S. laboratories. We publish the results. You verify the claims.

Manufacturing Standards

cGMP-Compliant Synthesis

Our peptides are synthesized in current Good Manufacturing Practice (cGMP)-compliant facilities using solid-phase peptide synthesis (SPPS) technology. Every step of the synthesis, cleavage, purification, and lyophilization process follows documented standard operating procedures (SOPs).

After synthesis, each compound undergoes purification via reverse-phase HPLC to achieve ≥99% purity. The purified peptide is then lyophilized (freeze-dried) under controlled conditions, sealed in sterile amber glass vials under inert atmosphere, and stored at -20°C until shipment.

Each vial is labeled with the product name, batch number, CAS number (where applicable), molecular formula, weight, purity, and storage conditions providing full traceability from synthesis to your bench.

The Six-Point Protocol

Full-Panel Analytical Testing

01

Identity

Mass spectrometry (MS) and high-performance liquid chromatography (HPLC) confirm the molecular identity of every batch, ensuring the compound matches its declared structure.

02

Purity

HPLC analysis quantifies the peptide purity to ≥99%, detecting and quantifying any impurities, truncated sequences, or residual synthesis byproducts.

03

Potency

Bioactivity assays verify that each batch meets established potency benchmarks, confirming the compound performs as expected in research applications.

04

Heavy Metals

Inductively coupled plasma mass spectrometry (ICP-MS) screens for heavy metal contamination including lead, arsenic, cadmium, and mercury.

05

Sterility

USP sterility testing confirms the absence of microbial contamination, ensuring the product is safe for in-vitro research applications.

06

Endotoxins

Limulus amebocyte lysate (LAL) testing quantifies bacterial endotoxin levels, verifying compliance with research-grade thresholds.

Transparency

Verify, Don't Trust

Every product in our catalog ships with a batch-specific Certificate of Analysis (COA). This document details the analytical results for your specific batch not a generic representative profile.

The COA includes HPLC chromatograms, mass spectrometry data, purity quantification, and pass/fail results for all six testing dimensions. We don't summarize. We don't paraphrase. We publish the raw analytical data.

Download the COA for any product directly from its product page. Cross-reference our results with your own analytical verification. That's not just transparency that's accountability.
