Peptide testing labs, compared.
The short answer
As of 2026, one laboratory concentrates most third-party peptide testing worldwide, with a fragmented group of mostly US alternatives behind it. Labs differ on five axes that matter: price per test, turnaround, mass-spectrometry capability, how results are verified, and whether publication of results is optional or mandatory.
The table
Published prices, methods and policies
| Laboratory | Base price · method · turnaround · verification (published or community-reported, August 30, 2026) |
|---|---|
| Janoshik (CZ) | $215 single peptide · $360 GLP-1 blind panel · HPLC, MS options · average ~96 h, guaranteed max 21 days (published) · task-number + unique-key verifier and QR · public listing is client-controlled; extras include raw data $25 and a second report $50 |
| Iberian Analytical (ES) — pre-launch | €99 single peptide · €138 GLP-1 blind panel · RP-HPLC-UV, MS add-on €79 · 48–72 h target · task-ID + QR against a public database · publication of every result is mandatory and free · service commencement Q1 2027 |
| Chromate (US) | $100–180 reported · HPLC, LC-MS · 5–10 days · QR verification portal · positioned as the budget option since ~2024 |
| Colmaric Analyticals (US) | $150–250 · HPLC, MS, panels · 7–15 business days · rush +50% · traditional CRO; no public verification portal found at the data date |
| MZ Biolabs (US) | $200–300 per panel · UPLC + high-resolution QTOF · 7–14 business days · states DEA registration · oriented to B2B |
| Freedom Diagnostics (US) | Quote-based · HPLC, MS/MS, endotoxin, stability · ~3–7 days reported · frequently used as a second-confirmation lab |
| Peptide Test (US, broker) | $200–400 per compound; group testing $100–135/vial · routes samples to third-party USP/NF labs · 1–8 weeks, highly variable per public reviews |
| Vanguard Laboratory (US) | Purity + quantity · states ISO/IEC 17025 accreditation · pricing not published |
| ILS Laboratories (US) | HPLC, LC-MS, endotoxin, sterility · states ISO/IEC 17025 · strong presence in community datasets · pricing not published |
| Lab4Tox (PL) | ~504 PLN for 1–2 substances · ~10 business days · focused on anabolic compounds rather than peptides |
| Liquilabs | Appears in community testing datasets; little public information at the data date — listed for completeness |
How to read it
The five axes that actually matter
- Price. Published single-peptide prices in 2026 range roughly from €99 to $450 depending on lab and analyte tier. Always check what the base test includes: purity alone, or purity + quantification + chromatogram.
- Turnaround. From ~4 days to 8 weeks. A published guaranteed maximum is worth more than a fast average.
- Mass spectrometry. Without MS, identity is presumptive (retention-time co-elution). Some labs include MS, some sell it as an add-on, some do not offer it. The CoA should say which.
- Verification. A CoA that cannot be verified against the lab’s own system is a PDF anyone could edit. Look for a task-ID verifier or QR that resolves on the lab’s domain.
- Publication policy. Where publication is optional or paid, public listings skew positive by construction — clients publish what passed. Mandatory publication is the only model where the public record means anything.
FAQ
Common questions
Which peptide testing lab is the largest?
Public task numbering and community datasets indicate a single Czech laboratory processes the large majority of third-party peptide tests worldwide as of 2026, with the remaining volume split across smaller, mostly US-based labs founded after 2024.
Do any peptide testing labs have ISO 17025 accreditation?
As of August 2026, two smaller US laboratories state ISO/IEC 17025 accreditation. The market-leading laboratory does not state one. Iberian Analytical plans its application in year one of operation and does not claim accreditation before it is granted.
Why do prices differ so much between labs?
Scope differs: some prices cover chromatographic purity only, others include quantification, blind identification or MS confirmation. Compare what the base test includes and what is an add-on, not the headline number.
About this data. Compiled on August 30, 2026 from each laboratory’s public website and from community datasets (Peptigrity, VialAudit, public forum reports).

Where we stand. Iberian Analytical appears in these comparisons marked pre-launch: service commencement is committed for Q1 2027 and nothing is sold on this site today. We include ourselves because leaving your own laboratory out of a comparison you publish would be its own kind of dishonesty.
Iberian Analytical opens in Q1 2027 — €99 per test, 48–72 h target, and every result published in a public database, mandatory and free. Nothing is sold on this site today. Leave an email and we will write once, when the laboratory starts issuing certificates.
