Certificates of Analysis · Testing methodology10x tested,
every batch,
every time.

Volta sends samples from every production batch to an independent analytical laboratory before release. Each batch goes through 10 tests across seven analytical panels: purity (HPLC-UV), identity (LC-MS), net peptide content, endotoxins (USP <85> LAL), microbial contamination (PCR), heavy metals (ICP-MS) and a fentanyl screen. The results are reported on that batch’s Certificate of Analysis, published below unedited with the laboratory’s own report ID.

01Purity

HPLC purity

Reversed-phase HPLC with UV detection: the main peak's share of the total integrated peak area, reported against the >99% release specification.

HPLC-UV

02Identity

Mass confirmation

Liquid chromatography coupled to electrospray mass spectrometry: the observed mass is read against the compound's expected mass, so the vial is confirmed to hold what the label names.

LC-MS

03Content

Net peptide content

The milligrams of peptide actually in the vial, measured against a calibrated reference-standard curve. Purity is a ratio, so this is the figure that says how much material is there.

Browse certificates

Every batch is released to a >99% HPLC purity specification, and a certificate for any other batch is available on request. Published results are free to read, quote and cite: every entry names its laboratory report ID, so any figure here can be put to the laboratory directly. If you are comparing suppliers, we would rather you read the certificate than take our word for it.

All materials are supplied for in-vitro laboratory research use only and are not for human or animal use. Certificates describe the tested batch and are not a claim of therapeutic effect.

Reading a Purity Figure

Three numbers, three different questions

>99% is the specification every batch is released to. The figure on a certificate is what a laboratory measured for one lot.

Purity specification

>99%

The release threshold. Every batch has to clear >99% by HPLC before it ships, and this is the figure quoted in the specification table on every product page. It is a standard, not a measurement.

Measured batch purity

e.g. 99.9%

The number an independent laboratory actually reported for one production lot, printed on that lot's Certificate of Analysis alongside the method, the date and the laboratory's own verification link. It is a measurement, not a standard, and it belongs to one lot only.

Batch number

e.g. VPBP10100

The string that joins the two. It is printed on the product page and on the vial, and the certificate for that lot prints it as the lot number, so a reader can confirm the certificate in front of them describes the vial in front of them.

Every Volta batch is released to a specification of >99% purity by HPLC. A Certificate of Analysis reports what an independent laboratory measured for one specific lot: a single figure such as 99.9%, on a named date, by a named method. Every product carries a batch number, and the lot number printed on its certificate is that same string, so the document can be matched to the vial rather than taken on trust.

Purity is one of 10 results on every certificate

A purity figure answers one question: how much of what is in the vial is the target compound. The same lot is also tested for the following, each by its own method, and every result is reported on that batch’s Certificate of Analysis beside the purity figure.

Mass confirmation

LC-MS

Liquid chromatography coupled to electrospray mass spectrometry: the observed mass is read against the compound's expected mass, so the vial is confirmed to hold what the label names.

Net peptide content

Quantified against a calibrated reference standard

The milligrams of peptide actually in the vial, measured against a calibrated reference-standard curve. Purity is a ratio, so this is the figure that says how much material is there.

Endotoxin

USP <85> LAL

Bacterial endotoxin by the Limulus Amebocyte Lysate assay, run in accordance with USP <85>.

Microbial screening

PCR

A polymerase chain reaction screen for the DNA of common microbial contaminants.

Heavy metals

ICP-MS

Elemental impurities (arsenic, cadmium, lead and mercury) by inductively coupled plasma mass spectrometry.

Fentanyl screen

Targeted screen

A targeted screen for fentanyl in the sample.

Everything above is Volta describing its own material. If you would rather verify it independently, we publish a directory of peptide testing laboratories with published prices, turnaround times and accreditation status, including labs we have no relationship with and corrections where an earlier entry of ours was wrong.

Each card summarizes the reported date, the measured batch purity and the mass from the certificate. Open one for the full results, the certificate page by page and every other report on file for the same compound, or download it as a PDF. Each also links to the laboratory's own verification page, so you can check the report against the lab rather than against us.

How to check a certificate

  1. Find the batch number on the product page, printed under the product name, and match it to the lot number on the certificate for that lot.
  2. Open the laboratory's verification link on the certificate card and confirm that the report number and the results match the laboratory's own record.
  3. Read the measured mass as well as the purity: purity is a ratio, so only the mass tells you how much peptide the vial holds against its label.

New to reading these? The complete guide to reading a Certificate of Analysis walks through a peptide certificate section by section: what the HPLC figure bounds and what it does not, why the detection wavelength changes the number, and which fields a reader should refuse to accept as blank.

Batch History

Every result we have published, in one file

One row per Certificate of Analysis: the batch number, the lot number the laboratory printed, whether the two agree, the measured purity, the net peptide content, the method and the laboratory's own verification link. Take the CSV into a spreadsheet and check us across lots rather than one page at a time.

Every published certificate, one row each. The file is rebuilt from the certificates themselves, so it gains a row the moment one is added.

Our Quality Promise

Research integrity depends on compound purity. We verify every batch so you can trust your results.

Independent Third-Party Testing

Every batch is tested by an independent analytical laboratory, never in-house only. This eliminates conflicts of interest and ensures objective purity verification.

10 Tests, Seven Panels

Each batch goes through 10 tests across seven analytical panels: purity (HPLC-UV), identity (LC-MS), net peptide content, endotoxins (USP <85> LAL), microbial contamination (PCR), heavy metals (ICP-MS) and a fentanyl screen.

>99% Purity Specification

Every product is released to a minimum threshold of >99% by HPLC. That is the specification, not a measurement: the certificate for each lot reports the figure the laboratory actually found. Batches below the threshold are rejected and never shipped.

Testing Process

From synthesis to your lab, every step is documented and verified.

  1. 01

    Synthesis & Purification

    Peptides are synthesized via solid-phase peptide synthesis (SPPS) and purified using preparative HPLC to remove truncated sequences and impurities.

  2. 02

    Independent Analytical Testing

    Each batch is sent to an independent third-party laboratory. Each batch goes through 10 tests across seven analytical panels: purity (HPLC-UV), identity (LC-MS), net peptide content, endotoxins (USP <85> LAL), microbial contamination (PCR), heavy metals (ICP-MS) and a fentanyl screen. The results are recorded on a batch-specific Certificate of Analysis.

  3. 03

    Batch-Specific COA Issued

    Each production batch gets its own Certificate of Analysis documenting the panel results and the lot number. The lot number on the certificate is the batch number printed on the product page and on the vial, so the document can be matched to the vial in your hand rather than taken on trust.

What's on a Certificate of Analysis

Every COA documents the analytical results for a specific production batch. Here's what each section means.

Product Identity

Compound name, molecular formula, molecular weight, CAS number, and batch/lot number for traceability.

Purity (HPLC-UV)

Reversed-phase HPLC with UV detection: the main peak's share of the total integrated peak area, reported against the >99% release specification.

Identity (LC-MS)

Liquid chromatography coupled to electrospray mass spectrometry: the observed mass is read against the compound's expected mass, so the vial is confirmed to hold what the label names.

Net peptide content

The milligrams of peptide actually in the vial, measured against a calibrated reference-standard curve. Purity is a ratio, so this is the figure that says how much material is there.

Endotoxins (USP <85> LAL)

Bacterial endotoxin by the Limulus Amebocyte Lysate assay, run in accordance with USP <85>.

Microbial contamination (PCR)

A polymerase chain reaction screen for the DNA of common microbial contaminants.

Heavy metals (ICP-MS)

Elemental impurities (arsenic, cadmium, lead and mercury) by inductively coupled plasma mass spectrometry.

Fentanyl screen

A targeted screen for fentanyl in the sample.

Appearance & Solubility

Physical characteristics of the lyophilized powder, color, form, and reconstitution behavior in standard solvents.

Finding your batch

You should not have to guess what is in your vial

A certificate is only worth reading if you can tell whether it describes the material you were sent. Every vial we ship carries a batch number and a QR code that resolve to one row in the archive above, which is the difference between a published result and a published result about your lot.

Volta Peptides GLP-3 RT 20mg vial, front of the label: the wordmark, the compound name, the 20 MG strength pill and the purity line.
Front
The same vial turned to the side panel, where the batch number VPRT20100 is printed above a QR code, labelled Scan for COA, that opens the third-party certificate of analysis for that lot.
Side panel
  • 1Unique batch number

    Printed on the side panel of the vial and on the product page. VPRT20100 is the compound, the fill and the batch, and it is the lot number on that batch's certificate.

  • 2QR to that batch's COA

    Beside “Scan for COA” on the same panel. Scanning it opens the third-party result for the lot in that vial, not a certificate for some other batch and not a marketing page.

Volta Peptides · Batch Verification

Verified. Traceable. Yours to check.

Every vial leaves here carrying its own batch number and a QR code that opens the independent laboratory result for that exact lot. Most suppliers publish one certificate for a compound and leave you to assume it covers the vial you were sent. We would rather you did not have to guess what is in yours.

Your batch results, one scan away.

  1. 01Turn the vial and scan the code

    The QR is on the side panel of the label, beside the words Scan for COA, not on the front. It opens the Certificate of Analysis for the lot in that vial, reported by an independent laboratory, with the purity figure, the method and the date on it.

  2. 02No camera? Match the batch number

    The batch number printed directly above the QR on that same panel is the lot number on the certificate. Look it up in the certificate archive and the two strings either match or they do not. Nothing has to be taken on trust.

QR code for batch VPRT20100. It opens the SideChain Analytics verification page for that certificate.

Try it on this batch

This is the live code for GLP-3 RT 20mg, batch VPRT20100. Scan it or click it and you land on SideChain Analytics's own verification page for report COA-2026-SC-02082, which reported 99.7% by HPLC-MS/MS on September 16, 2026.

Certificates of analysis: common questions

What does a certificate of analysis show?+

It records what a named laboratory measured on one lot, and it describes that sample rather than any other batch. Every product is tested on a seven-panel analysis by an independent laboratory: purity (HPLC-UV), identity (LC-MS), net peptide content, endotoxins (USP <85> LAL), microbial contamination (PCR), heavy metals (ICP-MS) and a fentanyl screen.

Which laboratory tests these lots?+

CoreMass Laboratories and SideChain Analytics. Every certificate here names the laboratory that issued it and carries that laboratory's own report ID.

How do I check that a certificate is genuine?+

Use the verify link beside the certificate, which opens the laboratory's own page for that report, or quote the report ID to the laboratory directly. Neither step depends on Volta Peptides.

Can I get the certificate for the batch I received?+

Yes. Published certificates are listed on this page, and new batches are added as they come back from the laboratory. For any other batch, email team@voltapeptides.com with the product and the lot number printed on the vial and we will send the certificate covering it.

How does >99% differ from the figure on a certificate?+

>99% is a specification: the release threshold a batch has to clear by HPLC. The figure on a certificate is a measurement a named laboratory made on one lot.
