Seven layers of testing. Zero guesswork.

High-resolution mass spec confirms the molecular weight matches the target peptide exactly — proving the vial contains the compound on the label, not a lookalike.

Why it matters — If the identity is wrong, every downstream result is wrong. This is the first thing that must be true.

Reverse-phase HPLC quantifies purity to ≥99% and resolves related-substance impurities, truncated sequences, and process residues.

Why it matters — Impurities introduce uncontrolled variables. ≥99% purity keeps your experiment measuring the compound — not the contamination.

Content analysis verifies the vial actually holds the stated amount of active peptide, correcting for water and counter-ion mass.

Why it matters — Accurate mass in = accurate concentration math out. No silent shortfalls between lots.

The Limulus Amebocyte Lysate (LAL) assay screens for bacterial endotoxins down to trace levels.

Why it matters — Endotoxins skew cell-based and in-vitro assays. Screening them out protects the integrity of sensitive research models.

Each lot is tested to confirm the lyophilized product is free of microbial contamination before it is sealed and released.

Why it matters — Contamination ruins samples and wastes weeks of work. Sterile in, reliable out.

Inductively coupled plasma mass spectrometry screens every lot for heavy-metal contaminants — lead, mercury, arsenic, and cadmium — down to parts-per-billion levels.

Why it matters — Trace metals catalyze degradation and confound sensitive assays. Verifying they’re absent protects both the compound and the data it produces.

An independent third-party lab confirms the analytical results, and every single lot ships with a lot-matched Certificate of Analysis you can match to the number on your vial.

Why it matters — Anyone can claim quality. We publish the proof — the data travels with the vial, verifiable before you ever open it.
