TB-500 research guide
TB-500 is a peptide name that can show up in chemistry databases, FDA status materials, product catalogs, and batch-level analytical records. Those source types are useful, but they do not prove the same thing. A public identity source can help check names and registry information. FDA material can provide regulatory and risk-context boundaries. A Purity Collective product page shows the exact commercial listing and the documents available for that listing.
This guide keeps those records separate. It is written for search clarity, product-record review, document comparison, and internal linking. It does not provide preparation instructions, use instructions, or outcome claims.
TB-500 identity and source context
PubChem lists a TB-500 compound record under CID 62707662. Public identity records are useful when a reviewer needs to compare a name, identifier, formula, or synonym against the wording used in a product listing. They are not Purity Collective lot documents and should not be treated as product-level evidence for any vial or blend.
FDA also includes TB-500 in its certain bulk drug substances safety-risk materials. That source is cited here as status and source-boundary context only. It is not a Purity Collective analytical report, and it does not replace product-specific documentation.
That separation matters because search results can blur together very different source types. A buyer may see a public database, a federal source, a product page, and a PDF report in the same research session. Those records should be read together only after their role is clear. The safest review habit is to attach every number to the specific record that produced it.
Purity Collective TB-500 10mg record
Purity Collective lists TB-500 10mg as a lyophilized-vial product for qualified laboratory research. The listing identifies TB-500, SKU PC-TB-500-10MG, a 10mg catalog quantity, and linked analytical documents.
The product page is the commercial record to review before ordering. This guide can explain the record structure, but it should not replace the product page or the attached reports. Product-level review still starts with the exact URL, listed title, SKU, quantity, visible document links, report fields, and any limitations printed or disclosed for the documents.
Purity also lists a related BPC-157 + TB-500 10mg blend. That blend has its own SKU, component split, batch record, and linked documents. TB-500 values from one product should not be copied to the other product unless the same report actually supports that statement.
How to review the TB-500 10mg UPLC/MS document
The TB-500 product page links a TB-500 10mg UPLC/MS report. The page states that the report identifies lot PCCL-4131262, records a measured quantity of 9.91mg against a 10mg specification, and records a 99.25% purity result against a greater-than-98% specification.
Those numbers are useful only while they stay attached to that document. The 10mg value is the catalog quantity. The 9.91mg and 99.25% values are report results for the submitted sample. They should not be rewritten as broad supplier promises or transferred to other TB-500 listings.
The same habit applies to dates and methods. A strong record keeps the compound, lot, method, received date, analysis date, specification, and result fields visible. Pulling one number out of the report makes the record easier to misread.
How to review the endotoxin document
The product page also links a separate TB-500 endotoxin report. The page states that the report uses related lot identifier PCCL-4131262-E and records a result below 0.05 EU/mL.
The limitation is important: the page notes that the endotoxin report does not print an acceptance specification. It also notes that the report lists an analysis date before the received date. Those fields should be preserved in the review record instead of being converted into a pass statement, a sterility statement, or a suitability statement.
The UPLC/MS report and endotoxin report answer different questions. One record supports identity, quantity, and purity review for its submitted sample. The other record reports an endotoxin result with its own lot suffix and chronology. Keeping them separate makes the listing clearer and safer to evaluate.
TB-500 vs BPC-157 + TB-500 blend review
The BPC-157 + TB-500 10mg blend should be reviewed as its own product. Its current certificate record represents the blend as 5mg BPC-157 and 5mg TB-500. The product page states that the UPLC/MS component report records BPC-157 at 4.90mg with 99.36% purity and TB-500 at 4.90mg with 99.19% purity.
Those component values are not the same as the standalone TB-500 10mg report. They belong to the blend’s batch record. The blend page also links a separate endotoxin report for a related batch identifier. As with the standalone product, the document should be read with its own lot, date, specification, and result fields visible.
For broader BPC-157 context, use the BPC-157 research and COA guide. For report-reading discipline across products, use the COA review guide.
A practical TB-500 record checklist
- Confirm the exact product URL: TB-500 10mg.
- Match the listed title, SKU PC-TB-500-10MG, vial format, and 10mg catalog quantity.
- Keep the 9.91mg and 99.25% values tied to the UPLC/MS report and lot PCCL-4131262.
- Keep the below-0.05 EU/mL value tied to the separate endotoxin report and related lot PCCL-4131262-E.
- Record the missing printed endotoxin acceptance specification and date chronology exactly as shown.
- Review the BPC-157 + TB-500 blend separately because its component results belong to a different product record.
- Use PubChem and FDA materials for identity/status context, not as Purity lot-level evidence.
TB-500 FAQs
What is TB-500?
TB-500 is a peptide name with a public PubChem identity record and product-specific analytical records on Purity Collective. For purchasing review, the practical question is which exact product page and document package are being evaluated.
Which Purity Collective page should I review?
The standalone listing is TB-500 10mg, supplied as a lyophilized vial for qualified laboratory research.
Which documents are linked for TB-500 10mg?
The product page links a UPLC/MS report and a separate endotoxin report. Each should be reviewed as its own record with its own lot, dates, specifications, and results.
What does the UPLC/MS report show?
The product page states that the UPLC/MS report records 9.91mg measured quantity and 99.25% purity for submitted lot PCCL-4131262. Those values are sample-specific report results.
What limitation applies to the endotoxin report?
The product page states that the endotoxin report records below 0.05 EU/mL but does not print an acceptance specification and displays analysis before receipt. It should not be rewritten as a pass, sterility, suitability, or safety statement.
Is TB-500 intended for human use on this site?
No. Purity Collective’s TB-500 listings are for qualified laboratory research only and are not for human or veterinary use.
