Independent Analytical Testing · ISO-aligned Methods

The verification standard for the peptide industry.

Amino Verify is an independent third-party laboratory program. We test peptide samples for identity and purity using HPLC and LC-MS, then publish the chain-of-custody and certificate of analysis to a public database.

The Method

A laboratory workflow, made transparent.

STEP 01

Submit & ship

Register a sample online, print a chain-of-custody label, and ship in a tamper-evident pouch. Tracking is bound to the sample ID.

STEP 02

Intake & weigh

On arrival, the seal is photographed, the sample is weighed under controlled conditions, and intake metadata is logged.

STEP 03

HPLC + LC-MS

Identity is confirmed by exact mass. Purity is measured by reverse-phase HPLC against a reference standard.

STEP 04

Signed COA

A reviewed certificate is published with the chromatogram, mass spectrum, and a permanent verification URL.

Services & Pricing

Transparent pricing. No retainers.

Pay per sample. Results are published to the public database within the stated turnaround.

Common Questions

Answers to the things that matter.

Are you affiliated with any vendor?+

No. Amino Verify is independently owned. We do not sell peptides, accept commissions, or guarantee outcomes for vendors. Trust scores are calculated from raw testing history.

What methods do you use?+

Identity is determined by LC-MS exact mass against a reference. Purity is measured by reverse-phase HPLC at 214nm using validated methods aligned with USP and EP monographs where available.

How does chain of custody work?+

Each sample is registered to a unique ID, sealed in a tamper-evident pouch, photographed on intake, and tracked through every analytical step. The full log is attached to the published COA.

Can a vendor pay to remove a failing result?+

No. Once a COA is signed by a reviewer it is published permanently. Vendors may submit a re-test from a new batch, which appears alongside the prior result.

Is this medical advice?+

No. Amino Verify performs analytical testing only. We make no claims about safety, efficacy, or therapeutic use. Reports describe the composition of a submitted sample.
