Axiom vs Vanguard Laboratory

A general analytical laboratory in Washington State. Peptide purity and quantity testing is one line of business alongside food and beverage, brewing chemistry, soil, allergen and terpene analysis.

Everything attributed to Vanguard Laboratory below was read on their own website on the date shown beside it, and every source is linked. Where they do not publish something, the page says so instead of guessing. Where they are ahead of us, the page says that too.

Where Vanguard Laboratory is ahead of Axiom

This section comes first deliberately. A comparison page that only flatters the lab that wrote it is worth nothing to a buyer, and you would find this out elsewhere anyway.

  • +

    Vanguard states ISO/IEC 17025 and publishes an A2LA Certificate of Accreditation on a dedicated page. Axiom does not hold ISO/IEC 17025 accreditation. That is the single biggest difference between us and it is in their favour. If accreditation is a requirement for your use, stop reading and use them.

  • +

    Their Level 2 and Level 3 tiers include a compendial sterility determination (USP 71) or bioburden (USP 61). Layer 4 of our panels is a rapid molecular screen and we label it a research screen, not a compendial sterility test.

  • +

    They require more than one vial as standard on the upper tiers: 2 vials at Level 2 and 4 at Level 3. Our panels are priced per vial, and cross-vial consistency is a paid add-on rather than the default.

  • +

    A much broader analytical scope: food and beverage, brewing chemistry, soil, allergen, terpene, residual solvent, pesticide and mycotoxin work. We do one thing.

  • +

    Their published 5-8 day purity and quantity turnaround is comparable to ours and their heavy metals and endotoxin at 3-5 days are faster than our 8X panel.

Side by side

Panels in this market do not answer the same set of questions, so the prices are not like for like. Read what each one includes before comparing the numbers.

Stated location
AXIOM ANALYTICS

Registered business address 2108 N St Ste N, Sacramento, CA 95816, USA. That is the entity's principal address, not a published laboratory street address, and it is not where samples are received: a receiving address is issued with each order.

VANGUARD LABORATORY

2635 Parkmont Ln SW, Suite A, Olympia WA 98502.

As published 2026-07-27 on Vanguard Laboratory, Peptide testing
Accreditation
AXIOM ANALYTICS

Not ISO/IEC 17025 accredited. Testing runs under a documented quality system and every method prints its own validation status beside the result it produced.

Derived from this application's pricing and method source of truth.
VANGUARD LABORATORY

States ISO/IEC 17025 in its peptide-testing FAQ, and publishes an A2LA Certificate of Accreditation image on a dedicated page. Also states HPLC methods validated to USP 1225 and Ph.D. chemists reviewing every result.

What a standard order covers
AXIOM ANALYTICS

Axiom 4X Essential $195: Molecular Mass Fingerprinting, Homogeneity Profiling, Net Peptide Mass Quantitation, Sterility Screen. Axiom 8X Comprehensive $595 adds Bacterial Endotoxin, Elemental Catalytic Sweep, Post-Reconstitution Stability, Fentanyl & Analog Screen. Endotoxin is available as a $50 module on 4X for injectable-format vials.

Derived from this application's pricing and method source of truth.
VANGUARD LABORATORY

Level 1 Silver: HPLC purity analysis, quantity/concentration, detailed COA, 1 vial. Level 2 Gold: Level 1 plus endotoxin testing, solubility check, and sterility USP 71 or bioburden USP 61, 2 vials. Level 3 Elite: Levels 1 and 2 plus heavy metals screening and priority processing, 4 vials. Heavy metals screening covers arsenic, cadmium, chromium, mercury and lead by ICP-MS. BAC water testing covers benzyl alcohol, pH and bioburden.

How identity is established
AXIOM ANALYTICS

LC-MS/MS (ESI+), included in the base panel. Theoretical mass, observed mass and the error in daltons and ppm are printed for every declared component.

Not published

The peptide-testing page describes HPLC purity and quantity analysis and does not state a separate identity determination or the instrument behind one. We are not inferring what is or is not run.

Published price
AXIOM ANALYTICS

Axiom 4X Essential $195 per vial. Axiom 8X Comprehensive $595 per vial. Extra same-lot vials for cross-vial consistency $195 each.

Derived from this application's pricing and method source of truth.
VANGUARD LABORATORY

Level 1 Silver $250. Level 2 Gold $550 (endotoxin listed as a $210 value). Level 3 Elite $700 (heavy metals listed as a $150 value). Conformity testing an additional $100. BAC water testing $200 per vial. Bulk and volume discount pricing offered.

As published 2026-07-27 on Vanguard Laboratory, Peptide testing
Published turnaround
AXIOM ANALYTICS

4-7 business days for 4X and 7-10 business days for 8X, measured from arrival of the vial at the lab rather than from order placement. USP 71 sterility, when ordered, runs on its own 14 day incubation timebase and is never folded into a fast tier.

Derived from this application's pricing and method source of truth.
VANGUARD LABORATORY

5-8 days for purity and quantity testing across all three levels. Heavy metals 3-5 days. Endotoxin 3-5 days. USP 71 sterility a 15 day minimum. Rush options available.

How a third party retrieves the certificate
AXIOM ANALYTICS

A public URL per released certificate, a verification page and QR, a public JSON endpoint, an embeddable widget, and published keys plus a signing recipe so the seal can be verified offline.

Derived from this application's pricing and method source of truth.
VANGUARD LABORATORY

A digital report and Certificate of Analysis delivered by email, plus a Verified by Vanguard programme with Silver, Gold and Elite marks for qualifying products after testing.

Where Axiom genuinely differs

Each of these is tied to something you can go and check on this site, rather than to an adjective. If the artifact named is not there, the claim is wrong and we want to know.

Identity by LC-MS/MS accurate mass is included in the base Axiom panel and printed with the theoretical mass, observed mass and the error in daltons and ppm. Vanguard's peptide-testing page describes purity and quantity and does not state an identity determination.

Check itLAYER_META layer 1, LC-MS/MS (ESI+)/protocol

Our certificate states the validation status of each method beside the result it produced (validated in-house, verified compendial, or research screen), and states plainly on every page that we are not ISO/IEC 17025 accredited.

Check itMETHOD_STATUS_META and the pinned accreditation notice on /protocol/protocol

Anyone holding an Axiom report ID can pull the laboratory record from a public URL and verify the seal offline. Retrieval does not depend on the vendor forwarding a PDF.

Check it/verify and GET /api/coa/{id}/how-to-verify-a-coa

What we could not establish

Gaps in our knowledge, stated as gaps. None of these is a criticism of Vanguard Laboratory, and none of them should be read as an absence of the capability. It means we did not find it published and we are not filling it in with an assumption.

  • ?

    The scope of their A2LA accreditation. The page publishes a certificate image; we did not extract the accredited test list from it, and an accreditation always applies to a defined scope rather than to everything a lab does. Ask them which peptide methods are in scope.

  • ?

    Whether identity is determined by mass spectrometry on any tier. Not stated on the pages we read.

  • ?

    Whether certificates can be retrieved by a third party who was not the submitting customer.
