Axiom vs Peptide Test

An online storefront selling per-compound purity and mass testing, plus lab supplies, with each compound listed as its own product.

Everything attributed to Peptide Test 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 Where they do not publish something, the page says so instead of guessing.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 Peptide Test 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.

  • +

    Per-compound product pages make the price for your specific compound obvious before you commit, including separate, clearly higher prices for two, three and four component blends. Our panel price is flat per vial regardless of how many components have to be resolved, which is simpler but tells you less about the work involved.

  • +

    They sell bacteriostatic water, filters and a starter kit alongside testing. We sell testing only.

  • +

    Several single-compound tests are listed from $200, close to our 4X price, and their blend pricing is explicit where ours is not differentiated.

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.

PEPTIDE TEST
Not published

We did not find a laboratory address on the ordering page we read.

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.

PEPTIDE TEST
Not published

No accreditation is claimed on the ordering page we read.

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.
PEPTIDE TEST

Purity and mass testing sold per compound, with extra vials at a discounted rate. Endotoxin, sterility, heavy metals, Karl Fischer water analysis and a vial vacuum test are sold as separate products. Blend assays are listed separately from single compounds.

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.

The collection page names the product Purity and Mass Testing but does not state the instrument or method. We did not find a method statement to quote.

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.

No turnaround is stated on the ordering page we read.

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.

The ordering page states results are delivered to the customer and does not describe a public lookup or verification route. We did not find one to link.

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.

Our published panel states what each layer measures, which instrument produced it, and that method's validation status, on the certificate itself.

Check itThe method-validation matrix on /protocol, rendered from the same LAYER_META that certifies each COA/protocol

A blend on an Axiom certificate passes identity only if every declared component has a real theoretical mass and a real observed mass within tolerance. One component confirming does not confirm the blend.

Check itcomputeLayerStatus layer 1, per-component pass rule/how-peptide-testing-works

Multi-vial submissions are scored as a consistency test: the lot mean must be on target and the vial-to-vial coefficient of variation must be within the acceptance limit, and both are printed.

What we could not establish

Gaps in our knowledge, stated as gaps. None of these is a criticism of Peptide Test, 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.

  • ?

    Which laboratory performs the analysis and where. Not stated on the page we read.

  • ?

    The method behind Purity and Mass Testing. The product name implies a mass determination; the page does not say by what instrument.

  • ?

    Turnaround, and whether certificates are publicly retrievable or verifiable by anyone other than the buyer.
