Peptide Testing Cost (2026)
Published per-sample pricing for every method we run, plus bundle pricing and volume breaks. No setup fees, no account minimums, no rush surcharge — turnaround is 9 to 11 business days for everyone.
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
| Test | Method | Cost 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'.
See what is included →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 9 to 11 business days at one price for every customer. We do not sell a queue position.
