The Wolverine Stack is the classic healing blend — BPC-157 (10mg) and TB-500 (10mg) pre-mixed in a single 20mg vial. One reconstitution, one injection, two complementary mechanisms: BPC-157 drives local angiogenesis and growth factor recruitment, TB-500 handles systemic cell migration and actin remodeling. It's the most popular blend for injury recovery because the pairing is well-established and the pricing math works out.
Research-context information only. The Wolverine stack is a research-peptide blend (containing BPC-157 and TB-500). Protocols, doses, and reactions reported below come from published research and self-reported community sources. This article reports what has been documented, not what should be done. Consult a licensed physician for personal medical decisions.
Short answer on the math: a Wolverine vial runs $48-135 across reputable vendors, while buying 10mg of each peptide separately runs ~$90 at mid-tier pricing. You save about 25-40% and get one injection instead of two. This guide covers how to verify a Wolverine vendor, what you should pay per milligram, how the blend compares to singles, and the red flags to avoid.
This is not a ranked vendor list — for that, see our Best Wolverine Stack Vendors comparison. This guide teaches you how to evaluate any blend vendor yourself.
Understanding Wolverine Stack Pricing
Wolverine is sold in two common sizes: 5mg/5mg (10mg total) and 10mg/10mg (20mg total). A few vendors stock a 5mg-only TB-500 variant, but 1:1 ratios are the standard. Pricing is driven by vial size, vendor markup, and testing investment — plus whether the vendor publishes per-component COAs.
Current Market Pricing (2026)
Vial Size Typical Price Range Price Per Total mg Best For 5mg / 5mg (10mg total) $48-85 $4.80-8.50/mg Tolerance testing, short 4-week cycles 10mg / 10mg (20mg total) $60-135 $3.00-6.75/mg Standard 8-week protocol — best value 5mg TB-500 only variants $48-90 $4.80-9.00/mg Less common; not the true Wolverine blend
The pattern is clear: the 20mg vial is the sweet spot. It's 30-40% cheaper per milligram than the 10mg version and lasts the standard 8-week healing protocol with just 2 vials. The 10mg vial only makes sense for tolerance-testing or ultra-short cycles.
Blend vs Buying Singles (Cost Per Cycle)
Using typical community vendor pricing, here's what the same peptide mass costs each way:
Peptide Amount Singles Price (mid-tier) BPC-157 10mg ~$45 TB-500 10mg ~$45 Singles total 20mg ~$90 Wolverine 20mg vial 20mg $60-110 Savings — 20-35%
The pattern is clear: even at the high end of Wolverine pricing, you save roughly $20-40 per vial vs buying singles. Over a standard 8-week cycle (2 vials), that's $40-80 in savings, plus half the reconstitutions and half the injections.

Cost Per Week at Standard Doses
Weekly Dose Monthly Cost (10mg vial) Monthly Cost (20mg vial) Savings 3.5 mg/week (500 mcg/day) $144-255 $90-203 ~30% 5.25 mg/week (750 mcg/day loading) $216-383 $135-304 ~30% 7 mg/week (500 mcg 2x/day acute) $288-510 $180-405 ~30%

How to Verify Wolverine Stack Quality
Blend COAs are trickier than single-peptide COAs. A vendor can pass a "blend purity" test while having the ratios off, or while having one component at 80% purity dragging the other down. For Wolverine specifically, you need per-component testing — separate HPLC for BPC-157 and separate HPLC for TB-500.
What a Wolverine COA Should Include
Identity Confirmation (Per Component)
Mass spectrometry confirming correct molecular weight for each:
BPC-157: 1,419.55 Da TB-500: 4,963.44 Da Amino acid sequence verification for each
Purity Testing
HPLC purity per component — look for 98%+ for each peptide individually Aggregate "blend purity" alone is not enough
Contamination Testing
Endotoxin (LPS) levels — critical for any injectable Residual solvent analysis (acetonitrile, TFA) Heavy metals screening
How to Verify a COA Is Legitimate
Not all COAs are real. Here's how to verify:
Check the testing lab — Reputable labs include Janoshik Analytical, MZ Biolabs, and Colmaric Analyticals. Avoid vendors who only show "in-house" testing.
Verify on the lab's website — Janoshik COAs have a task number you can look up directly at janoshik.com. If the vendor won't provide a verifiable task number, that's a red flag.
Check the date — COAs should be recent (within 6 months). Old COAs may not represent the current batch.
Match the batch — The batch/lot number on the COA should match what's printed on your vial.
Demand per-component data — For a 2-peptide blend, any vendor unable to show separate HPLC for BPC-157 and TB-500 is cutting corners.
Red Flags to Avoid
Single "blend purity" number with no per-component breakdown — the biggest blend-specific red flag No COA available — walk away immediately for any injectable research peptide Only in-house testing — self-reported purity is meaningless without independent verification Prices suspiciously low — Wolverine below $40/20mg across the board is a quality concern No endotoxin testing — injection safety issue, period Missing TB-500 mass spec — TB-500 is commonly mis-synthesized or substituted with thymosin beta-4 variants; verify the 4,963.44 Da molecular weight
Single Vial or Buy Singles: Which Makes Sense
The blend-vs-singles decision is about trade-offs, not just price. Here's the breakdown.
The 28-Day Reconstitution Window
Once reconstituted with bacteriostatic water, Wolverine follows the same stability rules as its components: up to 28 days refrigerated. That matters because a 20mg vial at 500 mcg/day lasts 40 days, which exceeds the window.
Vial Size At 500 mcg/day At 750 mcg/day At 500 mcg 2x/day 10mg total (5/5) 20 days ✓ 13 days ✓ 10 days ✓ 20mg total (10/10) 40 days ⚠️ 27 days ✓ 20 days ✓
⚠️ = exceeds 28-day window per reconstitution
Solution: For a 20mg vial at 500 mcg/day, reconstitute in two batches — add 1 mL BAC water for the first 28 days, then 1 mL more for the rest. Or use the full 2 mL upfront and plan to finish within 28 days by running a loading protocol.
When Blends Win
Cost savings — 25-40% cheaper per peptide mass than singles Fewer injections — one shot instead of two Simpler logistics — one vial, one reconstitution, one syringe draw per dose Pre-set 1:1 ratio — protocol is standardized; less room for dose error
When Singles Win
Dose flexibility — you can tweak BPC-157 up without also increasing TB-500 (common for tendon-specific protocols where BPC-157 does most of the work) Localized BPC-157 injection — if you want BPC-157 concentrated near an injury and TB-500 elsewhere, singles let you split sites Troubleshooting side effects — if you react to one, you can pull that component and continue the other Uneven cycle lengths — if you want 12 weeks of BPC-157 but only 6 of TB-500
Buying 10mg vs 20mg Vials
Factor 10mg vial (5/5) 20mg vial (10/10) Cost per mg Higher ($4.80-8.50/mg) Lower ($3.00-6.75/mg) Freshness Better (finishes in 20 days) Must plan around 28-day window Flexibility Short cycle friendly Commits to 40-day dosing Storage Easier Requires two-batch reconstitution Per-cycle math 4 vials for 8 weeks 2 vials for 8 weeks
Our recommendation: Go with the 20mg/vial for the standard 8-week cycle. Reconstitute in two 1 mL batches to stay inside the 28-day window. Only buy 10mg vials for tolerance testing or ultra-short 4-week protocols.
Vendor Evaluation Methodology
When comparing Wolverine Stack vendors, we weight three factors:
Price Competitiveness (40%)
We normalize to total cost per milligram across the full 20mg. A vendor at $60/20mg ($3/mg) scores higher than one at $110/20mg ($5.50/mg), all else being equal — but we penalize suspiciously cheap pricing that signals corner-cutting.
COA & Testing (30%)
For blends specifically, we verify:
Per-component HPLC (BPC-157 and TB-500 tested individually) Mass spec confirming both molecular weights Endotoxin testing Verifiable third-party lab (Janoshik, MZ Biolabs, Colmaric)
Reputation (30%)
Community feedback from peptide forums, shipping reliability, customer service responsiveness, and multi-year operating history. Blend specialists with consistent batch-to-batch ratios get extra weight.
Shipping and Storage
What to Expect When Your Order Arrives
Lyophilized Wolverine should arrive as a white or off-white powder cake in a sealed glass vial. Check:
Vial integrity — no cracks, rubber stopper intact, aluminum cap sealed Powder appearance — solid cake or loose powder, NOT liquid or discolored Labeling — batch/lot number, total mg, "for research use only" Cold pack — reputable vendors ship with cold packs in summer months
Storage Guidelines
State Temperature Duration Lyophilized (powder) Room temp Weeks (for shipping) Lyophilized (powder) Refrigerated (2-8°C) 12-24 months Lyophilized (powder) Frozen (-20°C) 2+ years Reconstituted (BAC water) Refrigerated (2-8°C) 28 days max Reconstituted (sterile water) Refrigerated (2-8°C) 24 hours Reconstituted Frozen Not recommended
Key point: The 28-day rule is the same as singles. See our Wolverine Stack reconstitution guide for step-by-step mixing.
