Wolverine

BPC-157TB-500 / TB4

Peptide blend of BPC-157 and TB-500, studied for soft-tissue and injury recovery.

A blend, not a compound

This is a combination sold as one vial. It has not been studied as a single substance, so what is known is what is known about each part, linked above. Sources that report a dose for the blend report it for that mixture, not for any component on its own.

How it is thought to work

Pairs BPC-157 and TB-500 repair peptides; studied for soft-tissue and injury recovery.

BPC-157 targets local tissue repair signaling (angiogenesis, growth factors) at the injury site, while TB-500 works systemically to promote cell migration and mobilization, with the two compounds hypothesized to cover non-overlapping repair pathways.

Reported side effects

No long-term human safety data exists for this stack; reported issues include mild injection-site reactions (redness, swelling, bruising), anecdotal lethargy or head-pressure with TB-500 loading, a theoretical cancer/angiogenesis concern, and quality-control risks from unregulated suppliers.

Who should avoid it

People with active or undiagnosed cancer and athletes subject to WADA/USADA testing should avoid this stack, as both compounds are prohibited and carry a theoretical angiogenesis-related tumor risk.

What gets monitored

Blood tests are mentioned (SiPhox Health At-Home Blood Test is listed as a recommended supply), but no specific labs or monitoring parameters are named on the page. [Source: peptidedosingprotocols.com]

Reconstitution, as reported
  • Reconstitute with 2.0 mL BAC water for a final concentration of 10 mg/mL total blend (5 mg/mL each component).
  • Pre-blended 20 mg vial: Add 2.0 mL bacteriostatic water → 10 mg/mL total (5 mg/mL each compound); 10 units (0.10 mL) delivers 0.5 mg BPC-157 + 0.5 mg TB-500; ~20 doses per vial at 1.0 mg/day. Separate vials: Add 2.0 mL BAC water to each 10 mg vial → 5.0 mg/mL each. Steps: allow lyophilized peptide to reach room temperature; wipe both vial stoppers with alcohol swabs; draw planned BAC water volume into sterile syringe; inject BAC water against inside wall of peptide vial slowly, never directly onto powder; swirl gently until fully dissolved, do not shake; verify solution is clear (TB-500 may appear very faintly tinted); refrigerate at 35.6-46.4°F (2-8°C) and use within supplier's stated beyond-use window.

Common questions

What is the Wolverine Stack?

The Wolverine Stack is a community shorthand for pairing two research peptides — BPC-157 and TB-500 — into one tissue-repair-focused protocol. It is not an FDA-approved treatment and not a clinical designation. The name comes from the comic-book character known for fast healing.

What is the typical Wolverine Stack dosage?

Two community-derived dosing models dominate. Pre-blended vial: 0.5–2.0 mg total of a 1:1 BPC-157 + TB-500 blend daily for 6–12 weeks. Separate vials: BPC-157 250–500 mcg daily plus TB-500 2–5 mg twice weekly during loading, with a tapered 8–12 week cycle. These are research-planning structures, not dosing recommendations.

Should I use a pre-blended vial or separate vials?

Pre-blended is simpler — one vial, one daily injection, locked 1:1 ratio. Separate vials let BPC-157 and TB-500 run on independent schedules (most often daily BPC-157 + twice-weekly TB-500 loading) and allow independent dose tuning. Both formats deliver the same compounds; the trade-off is convenience versus control.

What are the Wolverine Stack side effects?

There is no published human safety dataset for the combination. Compound-level reports from animal studies and small human exposure data describe low acute toxicity; the most common reported issue is injection-site reaction (redness, mild swelling, transient bruising). The most-cited theoretical concern is angiogenesis: both compounds promote new blood vessel formation, which is the intended repair mechanism but also a pathway relevant to tumor growth.

Is BPC-157 dangerous?

Animal studies and a small open-label human knee-pain case series (Vasireddi et al. 2025 systematic review, HSS Journal) reported no serious adverse events. There is no published long-term human safety data, no completed RCT, and the most-cited theoretical concern remains angiogenesis in the context of undiagnosed cancer. Quality of unregulated supply is also a real, separate risk.

Are BPC-157 and TB-500 FDA-approved?

No. As of June 2026, neither compound is FDA-approved. Both were removed from FDA 503A Category 2 on April 22, 2026, but neither is on Category 1 either. PCAC will evaluate both compounds on July 23, 2026, after which FDA will issue a 503A bulks-list determination. Both remain WADA-prohibited.

How long is a typical Wolverine Stack cycle?

Most community-derived protocols run 6–12 weeks total. A common separate-vial structure is 4 weeks of loading followed by 4–8 weeks of maintenance dosing. Pre-blended protocols often run a steady daily dose for the full cycle without a distinct loading phase. Off-cycle gaps of 2–4 weeks are commonly described but not formalized in any published trial.

Is there any direct evidence the Wolverine Stack works better than either peptide alone?

No published trial — preclinical or human — has tested the combination. The synergy argument is mechanistic, based on non-overlapping pathways for local repair (BPC-157) and systemic cell migration (TB-500). Compound-level evidence does not validate the combination.
