BPC-157 + TB-500 Wolverine Stack Dosage — Study Data Compared
BPC-157 and TB-500 wolverine stack dosage data from published animal studies. Individual peptide doses compared and blend pricing analyzed.
"Wolverine stack" is a term used in peptide forums as of around the year 2020. It refers to the combination of TB-500 (also known as thymosin beta-4 fragment) and BPC-157 peptide. The name comes from comic book stories about rapid tissue healing. The thrilling concept of the term has never been used in any official experiments. We will explain results of official studies performed with each of the two peptides, what doses were used by science, and what is contained in the blend of products available for sale.
Wolverine Stack Dosage - What the Name Refers To
BPC-157 and TB-500 Combined Use in Online Communities
Users of BPC-157 have shared their experience on reddit and various peptide boards, combining it with TB-500 and injecting both medicines subcutaneously at the site of injury. The idea behind using both BPC-157 and TB-500 together is that BPC-157 causes the formation of blood vessels while TB-500 works on actin polymerization so their effects are complementary in providing tissue repairing results. Nevertheless none of these reports is considered controlled evidence. They claim the doses of BPC-157 to be around 250-500 micrograms per day together with TB-500 of 2 to 2.5 milligrams.
What Published Research Actually Tested
All available research we found studied BPC-157 or thymosin beta-4 separately, using animals, rather than in combination. Both compounds have distinct histories of research where BPC-157 is derived from studies conducted in gastric juice by Sikiric et al. From Zagreb and thymosin beta-4 has been studied for its wound healing and cardiac repair benefits in the US.
BPC-157 Dosage Data in Isolation
| Study | Dose | Route | Model | PMID |
|---|---|---|---|---|
| Staresinic et al., J Orthop Res 2003 | 10 mcg/kg/day | Intraperitoneal | Rat, Achilles tendon transection | 14554208 |
| Sikiric et al., J Physiol Paris 1999 | 10 mcg/kg/day | Oral (gavage) and IP | Rat, multiple GI and soft-tissue models | 9920181 |
| Brcic et al., J Physiol Pharmacol 2009 | 10 mcg/kg/day | Intraperitoneal | Rat, crushed muscle injury | 20388964 |
| Sikiric et al., Curr Pharm Des 2018 (review) | 10 mcg/kg and 10 ng/kg ranges reviewed | Various (IP, PO, topical) | Rat and mouse models, review article | 29879879 |
Common Dose Ranges in Rat Studies
The dose reportedly used in BPC-157 studies is always 10 mcg for each kilogram of body weight and provided once every day to the subject by means of the intraperitoneal injection. Certain studies made attempts to evaluate even lower doses of BPC-157, i.e. 10 ng per kilogram. The review by Sikiric et al. In 2018 has summarized years of such dosing experiences for various studies dealing with different injury types, such as those inflicted to ligaments, muscles, guts, and nerves. No human equivalent dose has ever been tested in any of the studies conducted. The conversion of doses used in animal studies to human equivalent doses is very risky when no known human data are available for the peptide used.
TB-500 (Thymosin Beta-4) Dosage Data in Isolation
| Study | Dose | Route | Model | PMID |
|---|---|---|---|---|
| Malinda et al., J Invest Dermatol 1999 | 5 mcg per wound, topical | Topical application | Rat, full-thickness dermal wound | 10469523 |
| Philp et al., Ann N Y Acad Sci 2010 | 12 mg/kg | Intraperitoneal | Mouse, cardiac injury (coronary ligation) | 20633105 |
| Sosne et al., Expert Opin Biol Ther 2007 (review) | Various reviewed | Topical, IP | Multiple wound and ocular models | 17621012 |
Doses Used in Dermal and Cardiac Models
Thymosin beta-4 doses greatly differ from study to study. Studies performed by Malinda et al. Have only used 5 mcg of the drug in the area around a wound. Studies performed by Philp et al. On cardiac repair used a dose of 12 mg/kg administered intraperitoneally to mice. The Sosne review describes both topical treatment modalities and systemic approaches. TB-500 found on the market is a synthetic molecule of thymosin beta-4.
BPC-157 + TB-500 Combined - Was This Studied?
No Published Study Combined Both Peptides
Until now, we have searched PubMed for any studies on the co-administration of BPC-157 and thymosin beta-4 (TB-500) and have found none by October 2026. So far the combination is carried out only in self-experimentation and beamed advertisement. With no data from controlled trials, no effects and interactions can be ascertained yet.
Why the Stack Exists Despite No Combined Data
The reasoning is simple. In the animal studies, both peptides demonstrated properties of repairing tissues separately, and users of the forum concluded that by mixing the two, many more repair pathways would be activated simultaneously. Realizing the market potential, vendors started to sell premixed combination vials. This is a market-driven amalgamation rather than an evidence-based protocol design. The divide between the animal experiments with each peptide in isolation and the combination of peptides in humans is enormous.
Blend Products vs Separate Vials
PeptideGod BPC-157 + TB-500 Blend at $59.95
The combination vial labeled BPC-157 and TB-500 is priced at $59.95 by PeptideGod. The listing does not mention the milligram quantity of the two peptides included in the vial. Due to this lack of information, one has to make estimates and assumptions in order to determine the per-milligram price of the product as well as compare it with similar products. There is no certificate of analysis associated with the mixture appearing in the listing page.
Cost Comparison - Blend vs Two Singles
Purchasing BPC-157 and TB-500 separately will cost you $34.95 for BPC-157 and $35.00 for TB-500, making the total $69.95 (34.95 + 35.00 = 69.95). The blend will set you back just $59.95, saving you $10.00 over the cost of purchasing the two separately. The drawback of purchasing the two separately is that you have control over the ratio as well as the storage of each peptide. Whether the blend is a better deal depends on the amount of milligrams in it, which PeptideGod does not disclose for the blend.

FAQ - Wolverine Stack
Is the wolverine stack clinically tested?
No. There are no clinical trials published on either BPC-157 or TB-500 separately or of both of them mixed together with respect to their human use. In fact, all dose information originates from test tube studies conducted on mice and rats. The utilization of the term is purely informal.
What doses are in a typical blend vial?
The vendor dictates this matter. PeptideGod does not show the milligrams of each peptide source in their blend vial. Other vendors can show figures, e.g. 5 mg of BPC-157 plus 5 mg of TB-500, among which the difference can be substantial. Always check the label for the information about how much of each individual component is found in the blend product before buying it.
Is it cheaper to buy a blend or two separate vials?
PeptideGod’s blend ($59.95) is cheaper compared to the combined cost of BPC-157 ($34.95) and TB-500 ($35.00) by $10, but the price per milligram cannot be determined without knowledge of the amount of each chemical in the blend. If you want to be fully sure of the amount in each flask then you should opt for vials with measurable content.
