Every compound in the livvmore catalogue is organised two ways: by its compound identity and by the production batch it came from. “Documented by batch” is the second half of that. It means each physical run of material is tracked as its own unit, tested, and tied to a certificate that describes that exact run. This note explains what that documentation covers and how the pieces connect.
Why batches matter
A research compound is only as useful as the record that accompanies it. Two vials of the same peptide can come from different production runs, and a laboratory logging material into inventory needs to know which run a given vial belongs to. Tracking by batch makes that possible: every run is a distinct, identifiable unit rather than an anonymous entry in a catalogue. It also means a question about one run can be answered without casting doubt on every other run of the same compound.
How each batch is assigned
When a production run is completed, it is assigned a batch number and a lot number and recorded against the compound it represents. That identifier stays with the material from then on. It is printed on the vial label, written into the internal batch record, and carried onto the certificate of analysis, so the same lot number appears in all three places.
Identity and purity testing
Representative material from each batch is sent for third-party analysis at the USC Alfred E. Mann Multi-Omics Mass Spectrometry Core, a university laboratory. Two complementary methods are used. High-performance liquid chromatography (HPLC) separates the sample and records its chromatographic profile, which is used to assess purity. Liquid chromatography-mass spectrometry (LC-MS) and high-resolution mass spectrometry (HRMS) measure the mass of the compound so its identity can be confirmed against the expected value. Together these establish that the material in the batch is the compound it is described as, at the measured purity recorded on the report.
What the certificate of analysis records
The output of that testing is a certificate of analysis (COA): a structured report that states the compound tested, the batch and lot number, the analytical methods, the test date, and the results. Because it names the lot, the COA can always be matched back to the specific material it describes. Published certificates for the current batches are collected in the COA library, where each entry links to the product it belongs to.
How the records connect
The lot number is the thread that ties everything together. A vial label carries the lot; the batch record carries the same lot; and the COA carries it again. Starting from any one of the three, the other two can be located. That chain is what lets a certificate be read as belonging to the material in hand rather than to a different run of the same compound. A vial of retatrutide, for instance, can be traced from its label to its batch record to the certificate that documents that batch.
What this means when material arrives
In practice the documentation lets a laboratory do three things on arrival. It can confirm the vial corresponds to a specific, tested batch by checking the lot number. It can retrieve the matching certificate to see the analytical results for that batch. And it can cross-check the identity fields — the compound name, its CAS number and its molecular formula — against an independent reference before the material is logged. None of this rests on trusting a single label; every figure on the label is backed by a record that can be pulled and read.
The same standard across the catalogue
Every compound sold through livvmore follows the same documentation pattern, from the GLP research peptides through the copper peptides and the mitochondrial compounds. The method does not change from one product to the next: a batch is produced, assigned a lot, tested at the university core laboratory, and documented with a certificate that references that lot. Whether you are reading the research reference notes or an individual product page, the batch and testing information is presented the same way throughout.
Placeholders, not fabricated figures
Where a value has not yet been published for a batch, it is shown as a clearly labelled placeholder rather than filled in with an invented number. A figure only appears once it has been recorded, so nothing on a certificate or a product page is a guess presented as a measurement.
