Why the two compounds are studied together, how to verify two identities and two quantities on a blend COA, storage, and sourcing in Canada.
BPC-157 and TB-500 are the two most requested tissue-repair research peptides in Canada, and laboratories frequently source them together. A combination vial supplies both compounds in a single lyophilized preparation. It is convenient for research designs that call for both, but it also raises a verification question that single-compound vials do not: a COA for a blend has to confirm two identities and two quantities, not one. This overview covers why the compounds are studied together, how to verify a combined vial, storage, and what to check before ordering from a Canadian supplier.
For laboratory research use only. Neither BPC-157 nor TB-500 is approved by Health Canada for any medical use. The combination is not for human or veterinary use, food, or cosmetic applications. Nothing on this page describes or recommends administration to people or animals.
The VerifiedPeptides.ca combination vial contains 10 mg of BPC-157 and 10 mg of TB-500 (20 mg total) as a single lyophilized powder. BPC-157 is a 15-amino-acid synthetic pentadecapeptide (approximately 1,419 Da). TB-500 is the 43-residue acetylated thymosin beta-4 sequence (approximately 4,963 Da). Each compound has its own research overview on this site: BPC-157 and TB-500.
In the preclinical literature the two compounds are associated with different, complementary mechanisms in tissue-repair models. BPC-157 is studied for locally acting pathways — nitric oxide signalling, growth factor receptor expression in fibroblasts, and angiogenesis in injury models. Thymosin beta-4 is studied for systemic cell-level mechanisms — actin regulation, cell migration, and endothelial behaviour. Research designs that examine repair models from both angles are the reason combined preparations exist in the research market.
What the literature does not contain is controlled human clinical data on either compound, alone or combined. Both remain investigational research reagents, and a supplier that frames the combination as anything else is a supplier to avoid.
A blend needs more from its certificate of analysis than a single compound does. Check for all of the following.
Two identities. Mass spectrometry should show both expected masses — approximately 1,419 Da for BPC-157 and approximately 4,963 Da for TB-500 — in the same preparation. A COA showing only one mass has not verified the blend.
Two quantities. The certificate should state the content of each compound separately (10 mg + 10 mg), not a single combined figure. A blend that reports only "20 mg total" could contain any ratio.
Purity per compound. HPLC should resolve the two peptides as separate peaks, each with its own purity figure. Co-elution or a single reported purity value is a sign the analysis did not separate them.
Lot matching and independence. The lot number on the certificate must match the vial, and the testing laboratory should be named and independent of the supplier. Our guide on how to read a peptide certificate of analysis walks through each line.
Store unopened lyophilized vials at 2–8 °C, protected from light; −20 °C is preferred for long-term storage. Avoid repeated freeze–thaw cycles and aliquot once if the vial will be used across multiple experiments. Once reconstituted for an assay, the solution is far less stable than the dry powder — refrigerate, protect from light, use within the window stated in the documentation, and discard anything cloudy or showing particulate. Because the blend contains a 43-residue peptide, treat it with the same care as TB-500 alone. Our peptide storage and handling guide covers general lab practice.
Before ordering a BPC-157 + TB-500 blend from any Canadian source, confirm that a batch-specific COA from an independent laboratory is available for your exact lot; that it reports two identities, two quantities, and per-compound purity; that the supplier ships from inside Canada with a stated transit time; that the product is clearly sold as research use only with no claims about effects in people; and that payment can be documented. See how to vet a research peptide supplier in Canada for the full checklist.
VerifiedPeptides.ca supplies the BPC-157 + TB-500 20mg combination vial, as well as BPC-157 10mg and TB-500 10mg individually, for laboratory research, shipped from Canada in 1–3 business days with third-party testing on every batch. Published certificates are listed on our batch results page as they are released.
Is a combination vial better than buying the two compounds separately?
It depends on the research design. A combined vial is convenient when both compounds are used together in a fixed ratio. Separate vials allow each compound to be handled, verified, and stored independently, and allow the ratio to be set by the researcher.
What should the COA for a blend show?
Both expected masses by mass spectrometry, the content of each compound stated separately, and per-compound purity by HPLC with the two peptides resolved as separate peaks.
Is the BPC-157 + TB-500 combination legal to buy in Canada?
It is sold as a research-use-only reagent for laboratory study by qualified researchers and institutions. Neither compound is an approved drug in Canada, and the combination cannot legally be sold or marketed for human or veterinary use.
Does VerifiedPeptides.ca provide dosing or protocol information?
No. We supply research reagents and documentation of their identity and purity. Experimental design is the responsibility of the researcher and their institution.
