Every product ANKR Lab sells is manufactured to order, received in controlled batches, and tested by an independent laboratory before a single vial is released for sale. This page explains exactly what that process looks like, because “third-party tested” only means something when you can see the work.
Step 1: Every batch arrives quarantined
When a new batch arrives, it enters our inventory system in a pre-test state. Nothing from that batch can be assigned to an order, and nothing ships. The batch is logged with its own lot number, which follows it for life.
Step 2: Independent laboratory testing
Samples from each batch are sent to Freedom Diagnostics, an independent analytical laboratory with no ownership or financial ties to ANKR Lab. Two separate analyses are run:
Purity (HPLC-UV). High-performance liquid chromatography with UV detection measures what fraction of the material is the stated compound versus anything else. Recent lots in our library have measured between 99.2% and 99.8% purity.
Identity (LC-MS). Liquid chromatography–mass spectrometry confirms the molecular identity of the compound — that what is in the vial is actually the peptide named on the label, not a lookalike or a substitution.
Step 3: Pass, or never sold
A batch only becomes sellable in our system when its certificate of analysis comes back and meets our standards. Batches that fail are rejected and never reach inventory — the system physically will not assign a failed lot to an order. There is no override.
Step 4: The certificate follows every vial
Each vial is labeled with its lot number and expiry date, plus a QR code that links directly to that batch’s certificate of analysis. You never have to take our word for it or fill out a lookup form — the proof is one scan away, and every current certificate is published in our COA library with its purity result, test methods, and the full lab report PDF.
Why we publish all of it
Research depends on knowing exactly what a material is. Publishing every lot’s certificate — searchable by the lot number printed on the vial — is the simplest way to make our quality verifiable rather than claimed. If you ever receive a vial whose lot number does not appear in our library, contact us and we will resolve it immediately.
