Quality & documentation

Tested before it ever ships.

Purity isn't a marketing line — it's a document. Every lot is tested before release, and the paperwork travels with the product.

  • Identity and purity verified on every lot before release
  • Lot-matched Certificate of Analysis available on each product page
  • Full traceability from manufacture to your door
Laboratory quality control
The testing standard

Seven layers of testing.
Every lot earns its label.

Most suppliers ship on a supplier's word. Every batch here clears seven independent analytical checkpoints before it's ever listed — and if any layer fails, that batch never reaches you.

Verified at every step.
Pharmaceutical-grade active ingredient, tested before a single vial leaves the facility.
01
Identity — Mass Spec
High-resolution mass spectrometry confirms the molecular weight matches the target peptide exactly — proving the vial holds the compound on the label, not a lookalike.
02
Purity — HPLC
Reverse-phase HPLC quantifies purity to ≥99% and resolves related-substance impurities and truncated sequences — measured, not assumed.
03
Net Peptide Content
Content analysis verifies the vial actually holds the stated amount of active peptide, correcting for water and counter-ion mass.
04
Endotoxin — LAL
The Limulus Amebocyte Lysate assay screens for bacterial endotoxins to trace levels — the contaminants that quietly skew sensitive assays.
05
Sterility
Each lot is tested to confirm the lyophilized product is free of microbial contamination before it is sealed and released.
06
Heavy Metals — ICP-MS
Inductively-coupled plasma mass spec screens every lot for lead, arsenic, cadmium and mercury down to trace limits.
07
Independent COA
An independent third-party lab confirms the results, and every lot ships with a lot-matched Certificate of Analysis you can match to your vial.
Independent third-party verified — every lot, no exceptions.
The full Certificate of Analysis is available before you buy, not after.
