How much does peptide testing cost?

At Prodigy Labs the published ladder is $225, $595 and $995 per sample. The HPLC Package at $225 answers three questions on one certificate: identity by retention time against a reference standard run in the same sequence, purity by reverse-phase HPLC area percent, and content in mg per vial against the label claim from a whole-vial preparation measured against a standard of assigned potency. Tier 2 at $595 adds the injectable safety tests: endotoxin (USP <85>), heavy metals by ICP-MS and bioburden (USP <61>). Tier 3 at $995 adds the 14-day USP <71> sterility test, run in house, and LC-MS intact-mass identity. A blind identity test for an unlabeled vial is $250, and a reconstitution water panel (endotoxin, benzyl alcohol, pH) is $195.

It depends on one question: is the vial going to be injected? If not, the HPLC Package at $225 answers what you bought: the right peptide, how pure, and how many milligrams are in the vial. If it is, Tier 2 at $595 adds the three safety tests that purity cannot stand in for, and Tier 3 at $995 adds the true sterility test. Since September 2026 every HPLC order includes content, so there is no cheaper certificate that leaves the milligram figure off.

Usually because they are measuring less. A purity-only run is the cheapest product in this market and the most commonly advertised. Compare line by line rather than on the headline: is identity by retention time alone or confirmed against a standard, is content included or an add-on, what endotoxin method is used and against what limit, and if sterility is offered, is it a 14 day USP <71> incubation or a rapid screen presented as equivalent. Two quotes that differ by a factor of three often differ by more than that in what they tell you.

Intact mass confirmation by LC-MS is available as a $250 add-on where the use case needs molecular weight confirmation, and reconstitution stability (purity and content at day 14 and 28) as a $195 add-on. Beyond that, published pricing is the ladder above. Anything outside the standard menu is quoted rather than listed, because method development and unusual matrices are not priced sensibly in advance.

Yes. Volume pricing is published and applies automatically by the number of samples in a submission: 5 to 9 samples 5% off, 10 to 19 samples 10% off, 20 to 99 samples 15% off, and 100 or more at a 25% programme rate. The batch estimator on the pricing page shows the per-sample rate for your quantity, and there is no order minimum. Larger and recurring accounts can also get account pricing, which is quoted. Use the batch estimator or ask about account pricing.

Yes, at every tier. A certificate that can only be forwarded as a PDF is worth much less than one that can be checked against the issuing laboratory's records, particularly if it is going to a vendor, a partner, or into a dispute. Verify a Prodigy certificate.
