Peptide certificates of analysis in Australia
Every batch supplied by Australian Research Peptides is HPLC-tested and confirmed by mass spectrometry before release. Published certificates are listed below by product and strength — open one to read the laboratory’s own report, showing the testing date, method and result. All products are for in vitro research purposes only.
How every batch is tested by an independent laboratory
Every batch is tested before release by a laboratory with no commercial interest in the result. Two separate analyses are run — the first measures how pure the material is, the second confirms what it actually is.
Separates the peptide from everything else in the sample and measures what proportion is peptide.
Weighs the molecule to confirm it is the peptide named on the vial, and not something else.

Common questions about peptide certificates of analysis
A peptide COA — a certificate of analysis — is a laboratory report on one batch of material, recording what the peptide is, how pure the analysis found it, the method used and the date.
A certificate published on this page carries:
- The compound and strength the sample was submitted as
- What the laboratory was asked to test for
- A results table giving the measured amount of each component
- A purity figure, where the analysis produced one
- The date of the analysis
- The issuing laboratory and its own sample reference
“COA” here means certificate of analysis. It is not coenzyme A, which is an unrelated subject.
HPLC tested means the peptide has been run through high-performance liquid chromatography — the technique that separates a sample into its parts and measures what share of it is the peptide you ordered.
That share is the purity figure. HPLC stands for high-performance liquid chromatography.
“HPLC Verified” is the grade Australian Research Peptides gives every peptide it sells, and it means the batch was assayed this way before it was released for sale.
What the test does not do is confirm which peptide you have. A sample can be almost entirely one substance and still be the wrong substance, which is the job of the second test.
Mass spectrometry confirms identity: it weighs the molecule and compares that weight with the one expected for the peptide named on the vial. HPLC cannot do that, which is why both tests are run.
| Method | What it measures | What it cannot show |
|---|---|---|
| HPLC | The proportion of the sample that is the target peptide | Which peptide the sample actually is |
| Mass spectrometry | The molecular weight, matched against the weight expected for that peptide | How much of the sample is anything else |
Together they answer both halves of the question: how much, and of what. A report giving only one of them has left half the answer out.
Read a peptide COA in the order the document is built: check the compound and strength it names, then the result with the method beside it, then the date, then whether a purity figure is stated at all.
- Compound and strength. They should match what you are buying. A blend lists each of its components separately.
- The result and its method. A number with nothing beside it saying how it was produced cannot be checked against anything.
- The date. A report carrying none describes no particular moment.
- Whether purity is stated. Some analyses cover identity and amount only, and say so in the tests requested.
Our guide to reading a certificate field by field goes further than this answer does.
A peptide COA looks like a single-page laboratory report — an identifying header, a line stating what was requested, and a results table — and you can open real ones on this page rather than picture it.
Each certificate listed here opens as the laboratory’s own report, not a figure retyped into a web page and not a summary of the document.
Open one and read it against another. Comparing real reports is the fastest way to learn what a thin one looks like.
To get a certificate of analysis from a peptide supplier, ask for it and expect the laboratory’s own report rather than a promise. Australian Research Peptides publishes its certificates on this page.
For the report covering a particular parcel, message us with the order it came from.
A supplier who will show you a certificate only after you have paid, or who sends a screenshot of a number in place of the report, has told you something worth knowing. The document should be available before the purchase, not after it.
A genuine peptide COA comes from a laboratory independent of the seller, describes one specific sample rather than a whole catalogue, and carries a method and a date against every result on it.
What should make you look harder:
- A result printed with no method next to it
- The same figure appearing against every product a seller lists
- A purity claim with no identity test anywhere behind it
- A number retyped into a web page in place of the report itself
- A document carrying nothing that ties it back to a sample
None of these proves bad faith on its own. Several together mean you are reading marketing formatted as a laboratory document.
The certificates here that show no purity percentage are all blends. A single figure has no meaning for a vial holding two or three peptides, so the laboratory issues none for them and none is invented.
Those analyses cover identity and amount, and say so on the document. Australian Research Peptides does not average the components together, and does not borrow the figure from one component’s single-peptide certificate to stand in for the blend. The row shows what the document shows, and no more.
Australian Research Peptides sells a batch only at 99% purity or above. That is a release specification — the floor a lot must clear before it can be sold — not a measurement that applies to every vial.
The measured result differs from compound to compound and from lot to lot, so the number worth having is the one on that batch’s own certificate. Each published row on this page prints its own figure, read from the report rather than calculated from anything.
You cannot match a certificate to a vial by a batch number, because ARP vials carry none on the label. Match by product and strength, and for the lot in a particular parcel, ask us with the order reference.
Some of the published documents also carry no readable batch field of their own, so those cannot be tied to a printed code either way. That is how the laboratory issued them, and they are left as they are rather than tidied up.
Find the certificate by product and strength in the list above: every peptide strength Australian Research Peptides sells has its own row, and rows with a document published carry a link that opens it.
Rows are ordered with the published certificates first. A row with no link has no document yet — nothing else is substituted in its place.
A purity percentage is produced by laboratory chromatography, so it is not something a kit used outside a laboratory can give you. Australian Research Peptides does not sell a testing kit of any kind.
Every figure published on this page comes from instrument analysis, and identity comes from a mass spectrometer rather than from anything that can be read by eye.
What is worth doing at home is opening the certificate for the exact product and strength you bought, and checking that it names the compound you ordered.
The certificates on this page cost you nothing to open, and the testing behind them happens before a batch goes on sale. There is no testing fee to a customer.
Having a vial you already own analysed is a different thing, arranged directly with a testing laboratory. ARP does not offer that service and does not quote for it, so any price you have seen for peptide purity testing belongs to someone else.
If what you want is the certificate covering material bought here, there is nothing to pay — ask us and we will send it.
No. A certificate of analysis is a chemistry report on a batch — what the material is and how it measured — and not an approval of anything by anyone.
Everything Australian Research Peptides supplies is for in vitro research and is not for human or animal consumption. A strong analytical result and a fitness-for-purpose statement are separate claims, and only the first of them is on the document.
Peptide certificates of analysis in Australia are published on this page by Australian Research Peptides, an Australian supplier. Every peptide product and strength sold here is listed, with its laboratory report attached wherever one exists.
Stock is held and dispatched within Australia, and the analysis is carried out by an independent laboratory. What opens when you click a row is that laboratory’s own file — not a version of it rewritten for a website.
This page lists every peptide product and strength, and a certificate link appears only where a document exists for that exact strength. Rows without one say so; no placeholder or substitute certificate is ever shown.
A certificate belongs to the batch it was run on rather than to the product in general, so a strength carries its own document rather than inheriting one from anywhere else.
The count in the heading above the list is worked out from the documents themselves rather than typed in, so it cannot drift away from what you can see. If the strength you are buying has no certificate against it yet, ask us with your order and we will send the report for the lot you were shipped.
