BPC-157 + TB-500 blend COA documentation
COA documentation for BB10-style BPC-157 + TB-500 inquiries.
COA documentation guide for BB10-style BPC-157 + TB-500 lyophilized blend inquiries. Pepti confirms exact formula, HPLC purity, MS identity and lot documents before quotation.
Blend inquiry guide
Some buyers ask for BB10-style blend documentation. Pepti links the inquiry to confirmed BPC-157 + TB-500 formula, COA, HPLC, MS identity and lot traceability expectations.
This page is for buyers who ask for BB10-style BPC-157 + TB-500 blend documents. BB10 is handled as inquiry shorthand, listed through Pepti's BB10 / BPC-157 + TB-500 blend quote path. Exact formula and lot-document scope are confirmed before quote.
Product images are finished-vial display examples. Pepti primarily supplies peptide raw powder / lyophilized powder; neutral labels are default, and custom labels or branded packaging are optional services on request.
Documents
Every production lot includes a batch-linked COA, HPLC chromatogram and MS identity record. Water content, lot code and shipment documents are confirmed by RFQ and production lot.
RFQ path
Send compound list, quantity, target purity, destination market and document needs for a clearer manufacturer quote.
Boundary
B2B and research procurement only. Buyers confirm local regulatory compliance.
Why two-component COA review is different
A BB10-style preparation needs component-level evidence, not one generic purity line.
For a single peptide, COA review often centers on one HPLC purity value, one MS identity result and one batch number. A co-lyophilized BPC-157 + TB-500 preparation requires documentation that accounts for both compounds independently inside the same finished lot. A COA that reports only “Purity: 98%” without identifying BPC-157 and TB-500 separately is incomplete for two-component review.
BPC-157
CAS 137525-51-0, commonly referenced as a 15-amino-acid peptide in published preclinical literature. The component should be traceable in the analytical record.
TB-500 / Thymosin Beta-4
CAS 885340-08-9, commonly discussed as a Thymosin Beta-4/TB-500 peptide family reference. The component should not be hidden inside a combined result.
Shared finished lot
The finished blend should carry one lot reference that connects formula, lyophilization, vial labeling and document pack.
Buyer checklist
What BB10 document review usually includes.
| COA | Certificate of Analysis with batch identity, purity result and lot reference. |
|---|---|
| HPLC | Purity chromatogram and peak profile discussion before order confirmation, ideally with component-level review rather than a single combined purity percentage. |
| MS | Mass spectrometry identity confirmation for the stated components. |
| Buyer use | Document review for qualified B2B and research procurement only. |
Five core elements
What a complete BB10-style lot document package should answer.
1. Dual HPLC purity
Ask whether BPC-157 and TB-500 are reviewed separately. Resolved peak evidence is stronger than one combined number that cannot be assigned to either component.
2. Dual MS identity
MS identity records should support both stated components. Data for only one compound does not verify the blend as a whole.
3. Blend ratio check
BB10-style supply is usually a 1:1 concept, for example 5 mg + 5 mg per vial. The RFQ should state whether 5+5, 10+10 or 15+15 is requested.
4. Moisture / water content
Residual moisture is a stability-related parameter for lyophilized peptide preparations. Pepti confirms water content availability by current stock or production RFQ.
5. Lot traceability
The vial label, COA, chromatogram and MS record should connect back to the same production lot, not to unrelated old files.
Optional third-party test
Independent third-party testing can be arranged when a buyer needs extra verification before scale-up. Pepti does not claim every historical lot followed that path.
Red flags
Document gaps to catch before payment or scale-up.
Single combined purity only
A one-line purity value does not show whether BPC-157 and TB-500 were each reviewed.
MS for only one compound
Identity data for one component leaves the second component unconfirmed.
No ratio or per-vial formula
The document should state the requested blend format, such as 5 mg + 5 mg, 10 mg + 10 mg or 15 mg + 15 mg.
Two unrelated single-peptide COAs
Separate old COAs do not prove the current co-lyophilized finished lot.
No moisture information
Missing water-content discussion removes one useful lyophilized-powder quality indicator.
No batch linkage
If the COA, vial code and chromatogram cannot be linked, traceability is weak.
Questions before ordering
Ask these questions before approving a BB10-style RFQ.
- Is the requested material a true co-lyophilized BPC-157 + TB-500 preparation or two separately supplied peptides?
- Does the COA report component-level HPLC review for BPC-157 and TB-500?
- Is MS identity data available for both CAS references?
- How is the 1:1 blend concept or per-vial formula stated in the finished lot?
- What water-content, lot-code and shipment document fields are available for this RFQ?
Pre-purchase documents
What Pepti can confirm before quote finalization.
For active stock or production RFQs, buyers can request the available COA preview and confirm whether the lot file includes batch-linked COA, HPLC chromatogram, MS identity record, water-content field, neutral label or custom label details and shipment-document requirements.
Eligible sample path starts from 1 kit (10 vials). Production quote depends on RFQ quantity, formula, packaging scope, current stock or production schedule and destination market.
References and standards context
Use recognized analytical expectations, then verify the live batch.
Buyer teams often compare supplier documents against internal QC requirements, pharmacopeial thinking and general analytical principles such as defined specifications, validated identity methods, chromatographic purity review and batch traceability. For co-lyophilized research blends, the practical rule is simple: confirm both components, confirm the lot link and confirm what documents are available before payment.
