BPC-157 and TB-500 Stack in 2026 - Research Pricing and Vendor Data

The BPC-157 and TB-500 peptide stack has become one of the most discussed combinations in preclinical peptide research. Commonly called the "wolverine stack" in online forums, the pairing of these two peptides draws interest because each one has been studied independently for tissue-repair activity in animal models. We built this site to organize what the published literature actually says about the bpc 157 tb500 combination, compare the products available from US-based vendors and present pricing per milligram so researchers can evaluate these compounds on documented facts rather than marketing language.

What Is the BPC-157 + TB-500 Stack

BPC-157 at a Glance - Sequence, Origin, Study Focus

The synthetic pentadecapeptide known as BPC-157 (Body Protection Compound-157) has a sequence of GEPPPGKPADDAGLV and a molecular weight of 1419.53 g/mol. It was first discovered in a protein from human gastric juice by researchers from the University of Zagreb, Croatia. Most studies published on BPC-157 were conducted by this research group. The peptide has undergone experimental tests on rodents involving the gastro-intestinal, musculoskeletal , central nervous and cardiovascular systems. Its unique characteristic lies in remaining stable at low pH values of 1-2 for over 24 hours – a capability not shared by the majority of other peptides. BPC-157 has not been approved by any regulatory body, including the FDA.

TB-500 (Thymosin Beta-4) at a Glance

TB-500 is a synthetic fragment of Thymosin Beta-4 (TB4), a 43-amino-acid protein that plays a role in cell migration, proliferation and differentiation. The active region most commonly sold as TB-500 centers on the sequence LKKTETQ, which is the actin-binding domain of the parent molecule. Thymosin Beta-4 was originally identified in thymus extracts and has been studied for its role in wound repair, cardiac tissue recovery and inflammatory modulation. Like BPC-157, the research base consists primarily of animal studies and cell culture experiments. TB-500 is prohibited by WADA under the S0 category (Non-Approved Substances) and has no FDA-approved therapeutic use.

Why Researchers Pair Them - the Wolverine Stack Concept

The term "wolverine stack" originates from internet peptide forums and is inspired by the superhero’s remarkable ability to heal. The premise is simple: while BPC 157’s purpose such as vascular promotion and protective functions has been explored, TB 500 was examined regarding cellular migration and inflammatory processes. Bring them together, and it turns out that solutions to the constrained tissue recovery have been found. However, it is important to remember that this approach is not verified in any research that employed both BPC 157 and TB 500. Instead, the current explanation is based on data unrelated to the combination of peptides that has never been tested together. Our stacking benefits page elaborates on the rationale and its limitations.

What Published Studies Show About Each Peptide

BPC-157 - Preclinical Research Summary

More than 100 papers reference BPC-157, and the overwhelming majority use rodent models. A frequently cited study demonstrated accelerated Achilles tendon healing in rats after subcutaneous administration at 10 mcg/kg, with treated tendons showing increased load to failure and stiffness compared to controls (Chang et al., 2011). Gastric protection studies showed that BPC-157 reduced mucosal lesion area caused by ethanol and NSAIDs in rats at 10 mcg/kg through both oral and intraperitoneal routes (Sikiric et al., 1999). Separate work reported angiogenic activity, with BPC-157 promoting endothelial cell proliferation and tube formation through VEGFR2 signaling (Seiwerth et al., 2014). These are consistent findings across multiple rodent experiments, but none of them have been replicated in a controlled human trial.

TB-500 - Preclinical Research Summary

Thymosin Beta-4 research spans cardiac, dermal and musculoskeletal models. In a mouse model of myocardial infarction, intraperitoneal injection of 150 mcg of Thymosin Beta-4 reduced scar size and improved cardiac function compared to saline controls (Bock-Marquette et al., 2004). Dermal wound healing studies in rats showed that topical application of TB-500 accelerated wound closure and re-epithelialization (Malinda et al., 1999). The proposed mechanism centers on TB-500 sequestering G-actin monomers, which facilitates cell migration into damaged tissue. As with BPC-157, the evidence base is preclinical. No large-scale randomized human trial of TB-500 or Thymosin Beta-4 has been completed for a tissue-repair indication.

Data on the Combination - What Exists and What Does Not

We searched PubMed, Google Scholar and ClinicalTrials.gov for studies testing BPC-157 and TB-500 (or Thymosin Beta-4) together in the same experimental protocol. As of October 2026, we found no published study that administered both peptides simultaneously in a single animal model or cell culture experiment. The bpc 157 tb500 stack, as it is sold and discussed in online communities, has no direct experimental support for additive or synergistic effects. This does not mean the combination is harmful or ineffective. It means the data does not exist yet. Researchers considering this combination should understand that any expected benefit is extrapolated from separate studies on separate peptides in separate models. For a full comparison of how the two peptides differ, see our BPC-157 vs TB-500 page.

Product Comparison Table

The following table covers BPC-157 and TB-500 products from two US-based vendors: PeptideGod and Real Peptides. Every data point comes directly from each vendor's product page as of October 2026. PeptideGod sells the peptides individually and as a pre-made blend. Real Peptides sells them individually. The table includes pricing, stated amounts, purity documentation and current stock status. For dosage data from published studies, see our dedicated page.

How We Rank These Products

Testing and Purity Documentation

The most significant point of difference between the vendors we’ve sighted in this text is whether or not a Certificate of Analysis is made available prior to purchase. Real Peptides makes available lot-specific Certificates of Analysis (COA) for every peptide product, along with HPLC purity verification and endotoxin testing. The COA of BPC-157 shows at least 99% purity. The COA of TB-500 follows the same method of testing. PeptideGod does not publish any COAs on its product pages. This doesn’t necessarily mean that those products have not been tested, but it means that we cannot verify purity from the information provided. We place a huge emphasis on the availability of COAs when we prepare our rankings, and this is due to the fact that contamination is a common problem with research peptides, and purity issues could cause certain effects that are not related to the peptide itself.

Price per Milligram Math

Sticker price is misleading when vial sizes differ. Price per milligram is calculated for every product using the formula: listed price divided by stated milligrams. For the bpc 157 tb500 blend from PeptideGod, the 5mg vial works out to $11.99/mg and the 10mg vial to $10.00/mg. Buying BPC-157 and TB-500 separately from Real Peptides at 10mg each costs $43.20 + $48.00 = $91.20 for 20mg total ($4.56/mg average), which is less per milligram than either blend option. The trade-off is convenience: a single blend vial is simpler to handle than two separate vials requiring individual reconstitution. Our where to buy page walks through the full cost comparison.

Labeling and Product Information

Analysis is conducted on each vendor's product page in terms of vial size defined in milligrams, presence of storage instructions, mentioning of carrier/excipient (if applicable) and stating the purpose of the product. Real Peptides provides all of the mentioned specifications in addition to SKU for each product. PeptideGod specifies vial size and pricing levels on its pages but does not elaborate on storage instructions or composition of items. Both vendors, however, designate products for research purposes.
