Testing you can actually check
A laboratory report describes the sample and tests identified in that document. Request the applicable documentation and check its sample, test scope and batch relationship before interpreting a purity claim. A report alone does not establish suitability for human or veterinary use.
What to check when reviewing documentation
- Identify the lot or batch number on the relevant material
- Identify the laboratory and the submitted sample in the report
- Read each test result, method, unit and reporting limit
- Check the report’s stated batch and request clarification if the inventory relationship is unknown
Requesting documentation
For available product or lot documentation, email info@peptideserum.com. Use the appropriate request path below; documentation availability and its connection to the material need to be established rather than assumed.
Before ordering
Include the exact catalog product name and labeled quantity, and say that you do not yet have a vial or lot number. Ask which lot is currently offered, if known, what documentation is available, and whether that document can be connected to the material offered. A report shown as an example does not establish that it applies to an order.
If you already have the material
Include the product name, labeled quantity and lot or batch identifier exactly as printed on the label. Add an order number if available. If a field is absent, say unknown; a report identifier is not a substitute for a lot identifier.
A request you can copy
Product: [catalog name]
Labeled quantity: [amount and unit]
Status: [before ordering / material already held]
Lot or batch: [label value / not yet known]
Order number: [if available]
Please identify any documentation on file, what it measures, and whether its connection to this material or the currently offered lot can be established.
For an explanation of report fields and limitations, use the COA reading guide.

Request and record documentation for a specific lot
This page provides a documentation-request process; it does not currently publish a Peptide Serum inventory-to-lot report register. The Serum Research records used in our COA-reading examples illustrate document fields. They do not establish a match to Peptide Serum inventory or any batch currently being shipped.
Use the request path above, and record unknown when a field is missing. The checklist below describes information to request or record; it is not a list of available or verified reports.
- Product and material identity
- Exact name, relevant form or salt, and blend composition where applicable. Include the catalog identifier if available.
- Vial size or labeled quantity
- Record the labeled amount and unit, and whether it describes a vial, container or pack. A report for a different quantity does not establish a match.
- Lot or batch
- Copy the lot from the label and compare it with the document and inventory record. A report identifier is not a lot identifier.
- Laboratory and report identifier
- Record the issuing laboratory, report or task number, original document link, and any verification route the issuer provides. Preserve any limit caused by redaction or an unavailable issuer record.
- Report and sample dates
- Record the dates actually shown, including testing or issue dates where provided. A webpage access date is not a sample-testing date.
- Methods and reported results
- Record each method, finding or measured value, unit, reporting limit and qualification. Keep identity, purity and quantity separate; do not infer an unreported assay result from a document title.
- Scope and remaining uncertainty
- State what the supplied document establishes, which properties were not reported, whether the issuer record was checked, and whether the connection to current stock is documented or unknown. Purity does not establish sterility, endotoxin status, clinical benefit or suitability for human or veterinary use.
