A search for BPC-157 TB-500 blend Canada returns a long list of domestic suppliers, each selling a vial under the Wolverine Stack name. The name is borrowed from the Marvel character, and it spread through biohacking communities before it ever reached a product page.
The label is where the similarity ends. One supplier lists a 10mg vial and a 20mg vial at the same price. Purity documentation ranges from four dated third-party certificates down to a guarantee with no method behind it.
Across the five suppliers below, the most expensive vial costs more than twice the cheapest, and four list a 20mg option on their main page. ResearchedPeptides.ca ranks first for publishing identity data on both compounds, and it is also the dearest of the five.
Why the Wolverine Stack Is One of the Most Studied Dual-Peptide Combinations
The Wolverine Stack is studied because its two compounds act on different parts of the same tissue picture. BPC-157 research centers on blood vessel formation and tendon cells, and a 2025 narrative review frames that evidence base as preclinical. TB-500 research centers on actin dynamics and cell migration, so one does not replace the other.
BPC-157: The Angiogenic and Connective Tissue Compound
BPC-157 is a 15-amino-acid pentadecapeptide, which is where the older name pentadecapeptide BPC 157 comes from. One study ties its pro-angiogenic activity to VEGFR2 activation and upregulation, naming VEGFR2-Akt-eNOS activation as the associated pathway. Tendon models report effects on outgrowth, cell survival, and cell migration.
TB-500: The Actin-Sequestering Cell Migration Compound
TB-500 is built around the actin-binding domain of thymosin beta-4, a peptide reported to sequester the majority of G-actin in resting human neutrophils. A synthetic peptide carrying that domain reproduces part of the parent molecule’s activity in wound models.
Why Researchers Study Both Together: Complementary Pathway Activation
The BPC-157 work above sits at the tendon and the vessel wall. The thymosin beta-4 work sits at the actin cytoskeleton. One pre-blended vial reaches both without two reconstitution events and two storage schedules.
Our 5-Point Ranking Criteria for Canadian Wolverine Stack Suppliers
Five published details decide the order below. Every supplier here clears two, so they act as gates. Three separate the list: total compound mass, the analytical methods behind each component, and the paperwork on the product page.
Criterion 1: Total mg Per Vial, the Most Underrated Specification
Two formats cover almost every listing. A 10mg vial carries 5mg of each compound, and a 20mg vial carries 10mg of each, with bulk sizes running higher again. More compound per vial means more research cycles before a reorder.
Criterion 2: Dual HPLC and MS Verification for Both Components
A blend holds two compounds, so both need checking. HPLC reports purity and mass spectrometry confirms identity. A single run on the finished cake reports the mixture, and neither compound gets its own figure.
Criterion 3: 1:1 Mass Ratio and Transparency About the Ratio
Every supplier here lists a 1:1 blend, so the ratio itself doesn’t separate anyone. What varies is whether the exact mg figure appears on the product page or must be requested.
Criterion 4: COA and Sequence Data Published On-Page
Better documentation covers each compound before blending: a readable Wolverine Stack COA plus the sequence for both halves of the vial. These two come apart in practice.
Criterion 5: Domestic Canadian Shipping and Cold-Chain Integrity
All five ship from inside Canada, so this one is a gate too. A lyophilized blend is far more stable than the same material in solution, and a domestic parcel still skips the customs stage nobody controls.
Best Wolverine Stack Canada 2026: Five Suppliers Reviewed
Five Canadian suppliers stock a pre-blended BPC-157 and TB-500 vial. Each entry covers the mg split, price, documentation, shipping, and one honest limitation.
1. ResearchedPeptides.ca: Wolverine Blend 20mg
Both sequences and CAS are published. ResearchedPeptides.ca is our pick for the best Wolverine Stack Canada sells domestically, on the strength of what its product page prints. The vial contains BPC-157 10mg and TB-500 10mg (20mg total) at a 1:1 ratio, priced at $169.99.
Purity is stated per component, above 99% each, verified by HPLC and mass spectrometry. Both CAS numbers appear on the page, 137525-51-0 and 77591-33-4, alongside the full amino acid sequence for each compound. No other supplier here publishes that identity data, and an open lab-results library covers the wider catalog.
Dispatch is Canada Post Xpresspost from Vancouver, British Columbia, roughly two business days, with free shipping on orders over $199. Storage runs 2-8°C, or -20°C for extended preservation.
Its homepage credits an independent laboratory, Testides, but the Wolverine Blend page attributes the testing to no one. Two suppliers below name a laboratory on the listing itself, and neither publishes the identity data. Read the published reports at ResearchedPeptides.ca.
2. Durham Peptides
Popular for same-day dispatch. Durham Peptides puts both Wolverine Stack formats on one page, 5mg + 5mg and 10mg + 10mg, at the same $79.99 sale price against a $94.99 regular price. That makes its 20mg the cheapest in this comparison by $20.
Purity is quoted at 99% or above by HPLC, and every batch carries a report key you can verify independently.
Orders paid before 5:00 PM EST ship the same business day via Canada Post Xpresspost, domestically.
No laboratory is named on the product page or in the report-key guide, so the certificate’s issuer stays unstated.
3. VPeptide
A dated report per batch. VPeptide sells the Wolverine Stack as a 5mg + 5mg vial at $64.99, the cheapest entry point of the five. Larger 20mg and 70mg formats sit away from the main page, so the headline listing understates the range.
A separate certificate covers every batch, four of them, dated from September 2025 through to June 2026. Janoshik is named as the third-party laboratory, and purity is quoted at 99% or above by HPLC per component.
Orders before 5 pm ET ship the same day by Xpresspost, one to two business days within Canada.
The headline vial is the smaller one, so the 20mg tier takes some hunting.
4. NOX Peptides
Three batch purity figures on the page. NOX Peptides sells its Wolverine Stack as BPC-157 10mg with TB-500 10mg (20mg total) at a 1:1 ratio for $99.99. That is the cheapest 20mg vial here, printing its purity numbers on the listing itself.
The figures run 99.82%, 99.99%, and 99.80% across three batches, each linked to its report. Freedom Diagnostics and Testides are both credited across chromatographic and mass spectrometry methods.
Shipping runs via Canada Post from a Vancouver address, five to seven business days within Canada.
The product page itself gives no dispatch cutoff, so timing takes a second click.
5. Clinical Peptides Canada
One vial size, nothing to weigh up. Clinical Peptides Canada sells the 20mg Wolverine Stack and stops there, so you don’t have to choose a format. The split is BPC-157 10mg with TB-500 10mg at $139.00, the second-cheapest 20mg vial in this comparison.
Purity comes with a 99%+ guarantee, but it doesn’t state the method, credit a laboratory, or include a certificate on the page.
The listing shows the vial in stock with next-day dispatch from within Canada.
That leaves the thinnest documentation in this group, so confirm testing details before ordering.
Wolverine Stack Suppliers Canada 2026: Side-by-Side Comparison
Four of the five put a BPC-157 TB-500 20mg vial on their main listing. $90 separates the cheapest of those from the dearest, and $105 separates the cheapest listing of any size.

*VPeptide also lists 20mg and 70mg vials away from its main page.
10mg vs 20mg Wolverine Stack: Why Total Vial Content Matters for Research
Both sizes use the same 1:1 split, so the choice comes down to how far one vial goes. The 20mg format doubles the runs available at a fixed concentration, or supports higher-concentration work without a reorder. Four of the five list the larger size as their main option, and one prices both formats the same.
The Research Yield Difference: How Far Each Format Goes
Reconstitute a 10mg vial in 2mL of bacteriostatic water, and each compound sits at 2.5mg/mL. The same 2mL in a 20mg vial gives 5mg/mL of each. Stretch it to 3 mL, and you still have roughly 3.33mg/mL.
Why Pre-Blended Format Simplifies Dual-Protocol Research
Two separate vials mean two solvent calculations, two storage schedules, and two disposal records. A single lyophilized cake collapses that into one reconstitution and one concentration figure covering both compounds.
When Separate Vials Are Preferable to a Blend
A protocol calling for an uneven split, 2:1 BPC-157 to TB-500, for instance, needs the compounds ordered separately. Freeze-drying fixes the ratio, so a pre-blended vial only suits 1:1 work.
Reconstituting the Wolverine Stack: Key Protocol Notes for a 20mg Vial
A 20mg lyophilized cake needs more solvent than the smaller vials most handling notes describe, and it holds two peptide chains instead of one.
BAC Water Volume for a 20mg Lyophilized Cake
At 2.0mL of bacteriostatic water, a 20mg cake sits at 5mg/mL of each compound, and at 3.0mL it sits at roughly 3.33mg/mL. Add the solvent down the inside of the glass wall so it slowly reaches the cake.
Post-Reconstitution Storage for a Dual-Peptide Blend
ResearchedPeptides.ca lists 2- 8 °C for routine storage and -20°C for extended preservation. Lyophilized peptides hold up far better than peptides in solution, so the clock starts at reconstitution.
Peptide Calculator Reference
The peptide reconstitution calculator takes vial size and solvent volume and returns the figures, along with the supplier’s handling steps for storage.
Wolverine Stack Canada: Frequently Asked Questions
Where can I buy the Wolverine Stack (BPC-157 + TB-500) in Canada?
All five ship from inside Canada, so no customs step sits between the order and the bench. ResearchedPeptides.ca dispatches from British Columbia in roughly two business days. Durham Peptides and VPeptide ship same day before a 5 pm cutoff, and NOX Peptides quotes five to seven.
What is the difference between 10mg and 20mg Wolverine Stack vials?
Total compound mass. Both hold a 1:1 ratio, so a 10mg vial carries 5mg of each peptide and a 20mg vial carries 10mg of each. Across the four listings, a 20mg option costs $ 4.00 to $8.50 per mg.
Should BPC-157 and TB-500 be reconstituted in the same vial or separately?
One reconstitution covers a pre-blended vial, since the two compounds are combined before freeze-drying. The limit is flexibility: every aliquot carries both peptides in the same fixed proportion, so separate stock strengths need separate vials.
What purity should a Wolverine Stack vial have?
Look for 99% or above by HPLC on each component, with mass spectrometry confirming identity. Chromatographic purification separates the target peptide from impurities at 210-220 nm. Only two suppliers here quote purity per component so that a single blend figure can hide a weaker half.
Why is it called the Wolverine Stack?
The name points to the Marvel character’s regenerative ability, and it has become the informal industry term for the pairing. Certificates ignore it and list BPC-157 and TB-500 under their own names.
Best Wolverine Stack Canada: Our Final Verdict
Of the five, ResearchedPeptides.ca takes the top spot for identifying what sits in the vial. Each product page lists CAS numbers, amino acid sequences, and a purity figure, and no rival here publishes that set. It asks $169.99, and its testing laboratory is credited only on the homepage.
For Canadian labs sourcing a pre-blended stack domestically, ResearchedPeptides.ca lists its wolverine stack Canada vial at 20mg total, 1:1, HPLC- and MS-verified, dispatched from Vancouver, BC.
