How much does peptide testing cost?

At an accredited third-party lab in the US, peptide testing costs roughly $150 to $300 per sample for HPLC purity, $200 to $400 for LC-MS identity confirmation, and $800 to $2,000 for a full panel that adds endotoxin, heavy metals, residual solvents, and moisture. Stability studies and custom method validation are quoted per protocol and start around $1,500 and $3,500 respectively.

Cost per sample by method

Peptide testing cost per sample by analytical method
TestMethodCost per sample
Peptide purity testing

Quantitative purity percentage with chromatogram and related-substance profile.

RP-HPLC, USP <621>$150 – $300
Identity confirmation

Monoisotopic mass and sequence confirmation. Most COAs pair this with HPLC purity.

LC-MS/MS Orbitrap$200 – $400
Endotoxin testing

Required for anything headed into sterile compounding or injectable research use.

Kinetic chromogenic LAL, USP <85>$175 – $350
Heavy metals screen

Elemental impurity panel covering lead, cadmium, arsenic, and mercury.

ICP-MS, USP <233>$200 – $450
Residual solvents

Detects synthesis and purification solvents left behind in the lyophilized cake.

GC-HS, USP <467>$200 – $400
Karl Fischer moisture

Water content drives potency math and shelf-life. Cheap insurance on lyophilized lots.

Coulometric / volumetric KF$125 – $250
Stability study

Priced per protocol: timepoints, storage conditions, and number of attributes tested.

ICH Q1A(R2) accelerated / long-term$1,500 – $6,000
Third-party COA verification

Independent re-test of a supplier COA, with a side-by-side discrepancy summary.

HPLC + LC-MS against supplied COA$300 – $600
Custom method development

Scoped per project. Includes validation report and regulatory documentation.

ICH Q2(R1) validation$3,500 – $15,000

Ranges reflect sample count, sequence complexity, and whether a validated method already exists for the compound. Every quote we send back is a fixed price.

Bundle pricing

Purity + Identity

$350 – $650

The default panel. HPLC purity plus LC-MS identity is what most researchers and resellers mean when they say 'third-party tested'.

Compounding release panel

$800 – $1,600

Purity, identity, endotoxin, and moisture. Built around what 503A and 503B facilities need for incoming raw material and finished-product release.

See what is included →

Full contaminant screen

$1,000 – $2,000

Everything in the release panel plus ICP-MS heavy metals and GC-HS residual solvents. The complete 'is this safe' answer.

What moves the price

Sample count

Instrument setup and method equilibration are fixed costs spread across the run. Five samples of the same peptide cost far less per sample than five singletons of five different peptides.

Method availability

We hold validated methods for the commonly tested research peptides. A novel or heavily modified sequence needs method development first, which is quoted separately under custom analytical method development.

Reporting depth

A standard signed COA is included. Regulatory-grade documentation packages, raw data compilations, and audit-ready validation summaries add analyst time.

Turnaround

Nothing. Turnaround is 5 to 7 business days at one price for every customer. We do not sell a queue position.

Peptide testing cost FAQ

At an accredited third-party lab in the US, peptide testing costs roughly $150 to $300 per sample for HPLC purity, $200 to $400 for LC-MS identity confirmation, and $800 to $2,000 for a full panel that adds endotoxin, heavy metals, residual solvents, and moisture. Stability studies and custom method validation are quoted per protocol and start around $1,500 and $3,500 respectively.

Four things move the number: sample count, sequence complexity, whether a validated method already exists for that peptide, and reporting depth. A common GLP-1 analog on an existing validated method sits at the low end. A novel modified peptide needing method work sits at the high end.

Yes. Per-sample pricing drops at 5 or more samples and again at 20 or more. Labs and pharmacies running recurring quarterly QA panels are placed on standing customer pricing rather than being re-quoted each time.

Sample preparation, instrument time, peak integration, analyst review, and a signed Certificate of Analysis with the chromatogram attached. Raw data files are available on request at no additional charge. There are no setup or account fees.

No, because we do not offer expedited turnaround. Standard turnaround is 5 to 7 business days from sample receipt for every customer. Compressing analytical work is where transcription and integration errors get introduced, so we price and schedule one way.

A manufacturer COA is bundled into the price of the peptide, so it looks free. The real comparison is whether independent verification is worth $150 to $2,000 against the cost of a failed lot: wasted study time, discarded compounded product, or a supplier qualification that does not hold up under audit.

No. Send the peptide name, sequence if you have it, sample count, and which tests you need. Quotes are typically returned within one business day with a fixed price, not a range.

Payment is due on delivery of the Certificate of Analysis for first-time customers. Recurring institutional and pharmacy accounts can be set up on net terms with a purchase order.
