Research use only. This is laboratory material. It is not an approved medicine in Canada, it is not for human or veterinary use, and nothing on this page is dosing or administration guidance.
The short version
- BPC-157 and TB-500 supplied together in one 20mg vial of lyophilized powder. Two peptides, one vial, one batch number.
- Forums and search results call this pairing the “Wolverine stack”. The nickname is not ours and is not a claim about what the material does; it is simply what people type when they look for the BPC-157 / TB-500 combination.
- BPC-157 is a 15-amino-acid peptide whose sequence comes from a gastric protein. TB-500 is the supplier name for a synthetic fragment of thymosin beta-4. Both are research compounds; neither is an approved medicine anywhere.
- Every batch is tested by an outside lab. The report is on this page before you ask for it.
- Ships from inside Canada. No customs, no border risk.
What arrives
A sealed 20mg vial of lyophilized powder containing both peptides. Freeze-dried, so it is a solid cake or thin film at the bottom of the glass, not a liquid. Capped and labelled with the compound names, the size and the batch number. The two components are in one cake and cannot be separated afterwards, so if your work needs each compound on its own, buy the single vials instead.
How to read our lab report
Every batch goes to an outside laboratory before it is listed. The report gives two numbers that matter. Purity is how much of what is in the vial is the compound you paid for. Mass is how much material is actually in the vial. Purity is the number every supplier quotes; mass is the one many skip, and it is the one that catches underfilling. A vial labelled 10mg that measures 10mg or more was not shorted. A vial that measures 8mg is, whatever its purity says.
Ask any supplier for both numbers on the batch you are being sold, not a sample batch from last year. Ours included. The current report for this product is further down this page.

Shipping and payment
Orders leave from inside Canada, so nothing crosses a border and nothing gets held at customs. Express shipping is free over $250. Below that it is a flat rate shown at checkout. Payment is by Interac e-Transfer. Tracking is sent by email once the carrier has the parcel.
Where the Wolverine stack stands in Canada
Neither BPC-157 nor TB-500 is approved by Health Canada as a medicine, and no pharmacy stocks either. It is supplied here as laboratory material for research use only. The “Wolverine stack” label comes from forums, not from any regulator or manufacturer, and a nickname does not change the legal status of what is in the vial. The Canadian picture for each compound: BPC-157 in Canada and TB-500 in Canada.
Questions people ask before buying the Wolverine stack in Canada
What is the Wolverine stack?
A forum nickname for BPC-157 and TB-500 used together. This listing is that pair in one vial: 20mg of lyophilized powder containing both peptides, supplied as laboratory material for research use only. The name implies nothing about results, and we make no claims about what the combination does.
Is the blend better than buying BPC-157 and TB-500 separately?
Not better, just different. One vial means one reconstitution and one batch number. Separate vials mean each compound has its own lab report and can be handled on its own. If your work needs each peptide characterised individually, buy BPC-157 10mg and TB-500 10mg separately.
How do I check the lab report for a blend?
A blend report should name both peptides and give a result for each, not one purity number for the whole vial. The reports for this blend are further down this page, and each one gives BPC-157 and TB-500 a separate result.
Where do you ship the Wolverine stack from?
From inside Canada, by express courier. Nothing is imported to fill your order, so there is no customs step and no border seizure risk. Free over $250, flat rate below. Payment by Interac e-Transfer.

Why purity can differ a little between batches
Each batch is freeze-dried (lyophilized) in its own run. Small differences between runs and machines, such as temperature, drying time and the moisture left in the powder, affect how well the peptide holds up, and each raw peptide lot varies slightly too. The lab test (HPLC) also has a small margin from one run to the next. So one batch can read 99.8% and the next 98.6%, and both meet our 98% standard. That is why we send every batch to the same lab, Janoshik, and publish each report instead of quoting one best number. Some sellers never test at all, or show a report that was run for another company’s product with their own name on it. A report should match the product, the batch and the seller.
