What is in Wolverine, part by part
Each card comes from that peptide's own reviewed record. None of these records studied the mix.
Synthetic pentadecapeptide
BPC-157
EmergingSome studies in people exist. Important questions remain about benefit, safety, who it helps, or how long the effects last. This is not an approval or recommendation.- FDA status
- Still being studied; no FDA-approved BPC-157 product identified
- Evidence type
- Health results; use not approved
- Results in people
- Limited. Small uncontrolled pilots cannot establish a patient benefit.
- Safety known in people
- Limited. The human safety dataset is too small for confident risk estimates.
- Sports status
- Prohibited
- Last reviewed
- July 23, 2026
Cell and animal studies, plus small early studies in people, do not prove that BPC-157 heals injuries in people.
Synthetic thymosin beta-4 fragment
TB-500
InsufficientReliable studies in people are missing, too limited, or do not support the claim. This does not prove that the substance has no effect on the body.- FDA status
- No FDA-approved TB-500 drug product
- Evidence type
- Cell, animal, or product tests
- Results in people
- Unclear. FDA found no adequate human clinical outcome evidence for compounded TB-500 wound-healing use.
- Safety known in people
- Unclear. Human exposure and product-specific safety information are inadequate.
- Sports status
- Prohibited

A seven-amino-acid piece of thymosin beta-4 promoted for repair, without reliable human healing evidence and with major product and anti-doping limits.
What sellers mean by Wolverine
Three clinic pages checked in October 2026 describe Wolverine as BPC-157 and TB-500 given together. Two say the peptides come in one vial or one shot. None of them adds a third peptide.
One clinic says the name refers to the Marvel character Wolverine, who heals quickly. It calls Wolverine a nickname. The name sets no fixed amount or ratio, and sellers list different amounts of each peptide.
Some clinic pages call TB-500 thymosin beta-4. FDA describes TB-500 as a seven-amino-acid piece of thymosin beta-4. Research on the full protein does not carry over to the small piece.

Has anyone tested the mix in people?
No trial in people was found. On October 13, 2026, a PubMed search for BPC-157 and TB-500 returned 9 papers. Eight were reviews or overviews of earlier work. The ninth was a rat study.
ClinicalTrials.gov listed four studies of BPC-157 and one of TB-500 on the same day. None gives both peptides together.
The closest record in people is a 2021 look back at one clinic's charts. Of 16 people with knee pain reached by phone, 4 had shots of BPC-157 and thymosin beta-4. Three of those 4 reported relief.
That review had no comparison group, and people rated their own pain from memory. It cannot show that the shots caused the relief. It also names the full thymosin beta-4 protein, not TB-500.

What a 2026 rat study found about the mix
In a 2026 study, 32 rats had a cut Achilles tendon repaired. Groups got BPC-157, TB-500, both, or no peptide for four weeks.
The authors report that giving both peptides added no benefit over either one alone. TB-500 alone made the repaired tendon stronger than no peptide at four weeks.
Rat results can point to questions for human studies. They do not show what a vial does in a person.

Questions to ask about your vial
A seller name does not answer these. The label and records do.
- 01
Which peptides are in your exact vial, and how much of each?
- 02
Did the study you read test the mix, one peptide, or a different molecule?
- 03
Did the study test people, animals, or cells?
- 04
Do your sport's rules cover either peptide?
Fact checks for each part
Each result covers one peptide and the exact statement shown. It does not cover the mix.
BPC-157
“BPC-157 improves tendon healing in preclinical models.”
“BPC-157 heals tendons and muscles in people.”
“Athletes can use it because it is not a steroid.”
TB-500
“TB-500 is the same thing as thymosin beta-4.”
“TB-500 accelerates tendon and muscle healing in people.”
“TB-500 is allowed in tested sport.”
Sports rules for each part
These statuses do not give personal clearance to compete.
BPC-157
BPC-157 is listed under WADA's S0 non-approved substances category and is prohibited at all times for covered athletes.
ReviewedThe site will not provide self-injection, reconstitution, dosing, sourcing, or stack instructions. “Research use only” does not establish quality or make a product appropriate for human use.
TB-500
TB-500 is named as a prohibited thymosin-beta-4 derivative on the 2026 WADA Prohibited List and is prohibited at all times for covered athletes.
ReviewedThis is not an invitation to experiment. The guide provides no sourcing, reconstitution, injection, cycle, stack, or injury-treatment instructions.
What remains unknown
- No study in people reports side effects of the mix. Side effects of each peptide alone are also poorly known.
- The records do not show whether one peptide changes how the other acts in the body.
- The site gives no amounts, mixing, injection, cycle, or sourcing directions for either peptide.
The site does not provide dosing, sourcing, or treatment advice.
