Understanding your certificate of analysis
A certificate of analysis, or COA, is the documented record of what an independent laboratory actually found in a specific batch. Chemyo records one per batch so the contents of every bottle trace back to a real test, not a claim.
What a certificate of analysis is
A certificate of analysis is a formal document that reports an independent laboratory’s results for one specific batch of material. It is not a marketing summary and it is not a generic specification sheet — it is the recorded outcome of analysing the exact lot the bottle came from, tied to that lot by a batch identifier.
Because the testing is carried out by an accredited third-party laboratory rather than the supplier, the figures on the certificate reflect a measurement someone else made and signed off on. For research use, that distinction matters: a result you can attribute to a documented, independent test is something you can cite, file, and reproduce. A claim with nothing behind it is not. Chemyo issues a COA for each batch of its research-grade SARMs, nootropics, and metabolic reference compounds, and that certificate is available to review.
What is on a Chemyo COA
A certificate brings several pieces of information together on one page. These are the fields to look for, and the values described here are illustrative of what a typical certificate reports rather than fixed text.
Compound identity
The name of the compound the laboratory confirmed it was testing, so you know the certificate matches the material you ordered.
Purity result
The measured purity for the batch, typically reported above 99% for Chemyo solutions. This is the figure that tells you how little else is present alongside the compound.
Concentration or assay
The measured concentration of the active compound, confirming the solution contains what the label states. See our solutions
Analytical method
The technique used to obtain the result — for many compounds this is a chromatographic method such as HPLC. The certificate names the method so the result can be interpreted in context.
Batch identifier and test date
The batch code that links the certificate to your bottle, and the date the analysis was performed, so the record is anchored to a specific lot and point in time.
Issuing laboratory
The accredited ISO/IEC 17025 third-party laboratory that ran the test and stands behind the result. View lab accreditation
How to match your batch to its COA
Checking a certificate takes a minute and confirms that the document in front of you describes the exact bottle on your bench.
Find the batch code on your bottle
Look at the label on your 50 ml bottle for the batch code. Every Chemyo bottle is induction-sealed and batch-coded, and that code is what ties your specific lot to its certificate.
Locate or request the matching COA
Find the certificate for that batch in our documentation, or email sales@chemyolabs.co with your batch code and we will send the COA for your batch. Our support team replies within 1–2 business days.
Confirm the details match the label
Check that the batch code, compound identity, purity result, and concentration on the certificate match what is printed on your label. When they line up, you have a documented, independent record behind the material you are working with. For how those checks fit our wider process, see our quality control.
Why ISO/IEC 17025 matters
A laboratory can call itself competent, but accreditation to ISO/IEC 17025 means an external accreditation body has independently assessed that competence — the laboratory’s methods, equipment calibration, staff, and quality systems — against an internationally recognised standard. The assessment is repeated and reviewed over time, so it is an ongoing judgement rather than a one-off badge.
That independent assessment is what turns a number on a page into something you can rely on. When the purity and concentration figures come from an accredited ISO/IEC 17025 laboratory, they are not self-declared by the seller; they are produced by a lab whose ability to produce them has been checked by a third party. For research use, that is the foundation of reproducibility: results you can attribute to a verifiably competent source are results you, and others, can build on. It is the same standard that runs through how every batch reaches you — see how we handle quality control, and once a batch is in your hands, storage and handling keeps it true to its certificate.
