Testing Service
Why We Offer This
A vendor-side service, made open to anyone.
The research peptide market runs on opacity. Suppliers publish unverified purity claims. Buyers have no path to independent verification, and no recourse when claims don't hold.
OPTMZ Peptides built its own supply on third-party verification — every batch tested by Krause Analytical, every Certificate of Analysis published. Our testing service extends that same verification framework to researchers who need it for samples that didn't come from us.
"We don't sell verification. We sell access to the same lab partnership that backs our own catalog."
The same lab partner
Krause Analytical, DEA-registered, Austin TX — same lab that tests every OPTMZ batch. Same analysts, same protocols, same reference standards.
The same seven-method panel
HPLC, mass spectrometry, endotoxin (LAL), heavy metals (ICP-MS), microbial, pH stability, visual. The full analytical workup that every released OPTMZ batch must pass.
The COA is yours
The Certificate of Analysis is delivered to you as a PDF. We don't gatekeep it. Publish it, share it with your institution, attach it to grant documentation, archive it however you need.
Independence guaranteed
OPTMZ doesn't own Krause Analytical. We can't influence the result. Krause tests for multiple research-supply customers — they have no financial reason to bias any one supplier's outcome.
When To Use This Service
Four common ways researchers use this service.
If your work depends on the integrity of the input material, independent verification is worth running before you scale.
01 / VERIFY
Confirm a competitor's purity claim
You're considering a vendor that publishes a purity number but no supporting documentation. Send us a sample and receive an independent reading before you commit a research budget.
02 / VALIDATE
Third-party validation on synthesized samples
Your own lab synthesized a compound and you need outside analytical confirmation. We provide the same documentation framework we use for our internal catalog.
03 / DOCUMENT
Generate a COA for institutional records
Your IRB, research-facility documentation, or grant application requires an independent Certificate of Analysis. The COA you receive is suitable for institutional submission.
04 / COMPARE
Run side-by-side panels on multiple sources
Compare quality across suppliers without taking their word for it. Submit samples from multiple vendors, receive separate COAs, decide where to source from based on data.
The Process
Three steps. Seven to ten business days.
The submission flow is intentionally simple. The work happens at the lab.
01
Send
Request a submission kit through our contact form. Select "Custom testing request" from the subject dropdown so it routes to the right team.
- Submit the request through the contact form
- Receive your pre-paid mailer within 1–2 business days
- Mail your sample to Krause Analytical, Austin TX
— 2–4 business days total
02
Test
The lab logs your sample on receipt and runs the full seven-method analytical panel — same protocols as every OPTMZ batch.
- HPLC for purity quantification
- Mass spectrometry for identity confirmation
- Endotoxin, heavy metals, microbial, pH, visual
— 5–7 business days at the lab
03
Receive
The full Certificate of Analysis is delivered to you as a PDF. It includes every method, every reading, and the analyst's signature.
- Email delivery + downloadable archive
- Yours to publish, share, or archive
- Independent verification available by calling Krause directly
— COA within 24 hours of completion
The Deliverable
The Certificate of Analysis is yours.
Every submission generates the same document format we publish for our own catalog. Same fields, same rigor, same lab attribution — just with your sample's data instead of ours.

Common Questions
About the testing service.
Service-specific questions about submission, timeline, sample requirements, and what happens to your data. General testing methodology is documented on the How We Test page.
How do I submit a sample?
▾
Open the contact form and select "Custom testing request" from the subject dropdown. Include any relevant context — what you're testing, what scope you're looking for, and any institutional or batch details.
We respond with a pre-paid mailer, sample-tracking labels, and a one-page intake form within one to two business days. You include your sample and the form in the mailer and drop it in any USPS box.
— COA within 24 hours of completion
What's the minimum sample size?
▾
Details are included in the intake form sent with your submission kit — minimums vary slightly by compound and requested panel.
How long does the full process take?
▾
Seven to ten business days end-to-end: 2–4 days for kit delivery and mail-in, 5–7 days for lab analysis, and the COA is issued within 24 hours of completion.
Can I publish the COA I receive?
▾
Yes — the data is yours. Publish it, archive it, or share it with your institution however you need.
What happens if my sample tests below the standard?
▾
The COA reports the actual result either way. This is an independent verification service — we report what the lab finds, not what you'd prefer to see.
Is the testing service available to institutional researchers?
▾
Yes — this service is commonly used for IRB documentation, grant-related sample verification, and institutional research records.
