Key takeaways
- Both vials hold 5 mg of lyophilized peptide at ≥99% purity by HPLC, so purity is not the deciding factor.
- BPC-157 is $64.99 CAD per vial; TB-500 is $79.99 CAD per vial.
- BPC-157 and TB-500 are distinct sequences and are not interchangeable in an assay.
- Storage handling is identical: sealed lyophilized vials, cold-chain packaging with desiccant on arrival.
- Each lot ships with a downloadable certificate of analysis stating identity, purity and test method.
The short verdict
We supply BPC-157 Lyophilized Peptide and TB-500 Lyophilized Powder in 5 mg vials at ≥99% purity by HPLC. The two reagents are matched on quantity, format, purity method and documentation, so selection comes down to the peptide identity a protocol calls for and the budget line: $64.99 CAD for BPC-157, $79.99 CAD for TB-500.

Identity and sequence class
BPC-157 is a synthetic pentadecapeptide, a 15-amino-acid sequence derived from a gastric protein fragment. It is widely catalogued under the name Body Protection Compound-157 and is supplied as a lyophilized powder.
TB-500 is a synthetic peptide fragment associated with thymosin beta-4. It is a shorter sequence than the full protein and is also supplied lyophilized.
The two are distinct molecules with distinct molecular weights. They are not interchangeable in an assay. Researchers selecting between them should match the sequence named in the protocol, not the product category. Identity for each lot is stated on the certificate of analysis that accompanies the shipment, alongside purity and test method.
Both sit in our Research Peptides catalogue with the same vial format, so a lab ordering both receives consistent packaging and documentation.
Purity and test method
Both reagents are specified at ≥99% purity by HPLC. Purity is always paired with its test method on our documentation. We do not state a purity figure without naming how it was measured.
Testing is third-party HPLC and mass spectrometry. Mass spectrometry supports the identity statement; HPLC supports the purity figure. The certificate of analysis for each lot records identity, purity and the test method used.
Because the two peptides share the same purity specification, purity is not a deciding factor between BPC-157 Lyophilized Peptide, 5 mg per Vial and TB-500 Lyophilized Powder, 5 mg per Vial. What differs is the molecule and the price per vial.
Storage and cold-chain packaging
Both peptides arrive as lyophilized powder. Lyophilized material is less sensitive to ambient conditions than solution, but it remains hygroscopic. Moisture ingress is the main storage risk for either vial.
Each vial travels in cold-chain packaging with desiccant. The desiccant is there to limit moisture exposure in transit. On arrival, laboratories typically transfer lyophilized peptide vials to cold storage and keep them sealed until the protocol requires otherwise.
Storage handling is identical for the two products. A lab that has a working procedure for one 5 mg lyophilized vial does not need a second procedure for the other.

When BPC-157 is the right line item
Choose the BPC-157 vial when the protocol names the pentadecapeptide sequence specifically, or when a reference compound is required for a comparison against that sequence.
It is also the lower-cost of the two at $64.99 CAD per 5 mg vial. For method development, column calibration or a first pass where the peptide identity is flexible within a study design, the price difference of $15.00 CAD per vial is a legitimate factor across a multi-vial purchase order.
Purchasing officers should note the vial content is 5 mg. The 0.05 kg figure on the shipping record is the packed weight for the courier, not the net content. Carton dimensions are 8×8×6 cm.
When TB-500 is the right line item
Choose the TB-500 vial when the protocol calls for the thymosin beta-4 fragment. No substitution applies here; the sequence is different and the molecular weight is different.
The price is $79.99 CAD per 5 mg vial. Format, purity specification, test method, documentation and packaging match the BPC-157 item, so a shared receiving and storage workflow covers both.
Labs running both peptides in parallel often order one vial of each, since the carton size and packed weight are the same and shipments consolidate cleanly.
Consumables and ordering
Both vials are sold as lyophilized powder only. Bacteriostatic water and sterile 10 mL glass vials are stocked separately under Lab Supplies, and are commonly added to the same order to keep documentation and delivery in one tracked parcel.
Catalogue prices across the range run from $24.99 to $219.99 CAD; the TB-500 5 mg vial is $79.99 CAD. Shipping is tracked from Vancouver to Canadian addresses, with the province and postal code taken at checkout.
Ordering is limited to laboratories and qualified researchers. Each lot ships with a downloadable certificate of analysis stating identity, purity and test method, and each vial travels in cold-chain packaging with desiccant.
For laboratory research use only. Not for human or veterinary use.
