About BPC-157 / TB-500
A precision research blend of BPC-157 (10mg) and TB-500 (10mg), two of the most studied synthetic peptides in current preclinical literature. Investigated in laboratory models examining cellular signaling interactions, actin-binding mechanisms, and extracellular matrix pathway activity.
In controlled research models, BPC-157 has been studied for modulation of nitric oxide signaling pathways and cytokine expression in cellular environments. TB-500 research has examined upregulation of actin-binding proteins and neovascularization mechanisms at the cellular level. Combined formulation enables researchers to study potential synergistic interactions within controlled in-vitro environments.

Store the lyophilized powder at −20°C in a standard laboratory freezer, protected from light, moisture, and heat. Avoid repeated freeze-thaw cycles.
Shelf Life
Per the manufacturer, the lyophilized powder remains stable for 12–24 months when stored frozen in its original sealed vial. Our release testing verifies identity, purity, content, and the contaminant panels and does not itself establish shelf life.
Mechanism & Research Background
Wolverine combines two of the most heavily studied synthetic peptides in current preclinical research literature, BPC-157 and TB-500, at 10mg each in a single 20mg lyophilized vial. The pairing reflects a research design grounded in the distinct, complementary cellular pathways each peptide engages: BPC-157 (Body Protection Compound 157) operates through pentadecapeptide signaling and angiogenesis-related pathway modulation, while TB-500 (a synthetic fragment of thymosin β4) acts through actin-sequestering and cell-migration mechanisms. Both peptides have independent corpora of peer-reviewed research on PubMed; the blend is formulated for researchers investigating potential combined or sequential exposure within controlled in-vitro environments.
In pathway research, BPC-157 is a synthetic 15-amino acid peptide derived from a sequence found in human gastric juice. Published preclinical work has examined its activity at the cellular level across nitric oxide signaling, cytokine modulation, fibroblast biology, and angiogenesis pathway markers (Seiwerth et al., Front Pharmacol, 2021; Sikiric et al., Gut Liver, 2020; Gwyer et al., Cell Tissue Res, 2019). TB-500 is the synthetic active fragment of thymosin β4, an actin-sequestering protein with characterized effects on cell migration, neovascularization markers, and extracellular matrix interactions in preclinical research models (Goldstein et al., Trends Mol Med, 2005).
The blend formulation enables researchers to examine combined exposure to both peptides without the experimental variability of two separately reconstituted preparations. Each batch is independently tested at ILS Laboratories: purity and quantitation by HPLC, heavy metals by ICP-MS (lead, arsenic, cadmium, chromium, and mercury), bacterial endotoxin by USP <85>, and a rapid microbial screen (DNA microarray), with three vials providing the material for the complete ILS panel and two additional vials each tested for HPLC purity, identity, and net peptide content to evaluate conformity; the Certificate of Analysis reflects the combined-peptide composition. Products supplied by Virtus Peptides are for in vitro laboratory research use only, not for human or veterinary use, not for diagnostic, therapeutic, or clinical use, and not intended for consumption or administration.
Frequently Researched Questions
What is Wolverine?
Wolverine is a precision research blend combining BPC-157 (10mg) and TB-500 (10mg) in a single 20mg lyophilized vial. The blend is formulated for researchers studying potential combined effects of pentadecapeptide signaling (BPC-157) and actin-sequestering protein activity (TB-500) in controlled in-vitro environments.
How much BPC-157 and TB-500 is in each vial?
Each Wolverine vial contains 10mg of BPC-157 and 10mg of TB-500, lyophilized together in a 20mg combined preparation. Both peptides are independently tested for purity prior to blending.
Why blend BPC-157 and TB-500 together?
The two peptides have non-overlapping mechanisms in published research literature: BPC-157 has been studied in angiogenesis pathway and cytokine signaling research, while TB-500 contributes characterized actin-sequestering and cell-migration activity. The blend allows researchers to examine potential synergistic interactions in a controlled in-vitro setting without the variability introduced by two separately reconstituted preparations.
What testing does Virtus Peptides run on Wolverine?
Every batch of Wolverine is independently tested by ILS Laboratories (ISO/IEC 17025 accredited) across the full QC panel: purity and quantitation by HPLC, heavy metals by ICP-MS (lead, arsenic, cadmium, chromium, and mercury), bacterial endotoxin by USP <85>, and a rapid microbial screen (DNA microarray). Three vials provide the material required for the complete ILS quality control panel, and two additional vials are each tested for HPLC purity, identity, and net peptide content to evaluate conformity. The Certificate of Analysis reflects the combined-peptide composition.
How should Wolverine be stored?
Lyophilized Wolverine should be stored at −20°C, protected from light, in the original sealed vial. Repeated freeze-thaw cycles should be avoided. Per the manufacturer, the sealed lyophilized material has a stated frozen storage period of 12 to 24 months. Virtus Peptides release testing does not independently establish product shelf life.
Where can I find published research on BPC-157 and TB-500?
PubMed indexes peer-reviewed research on each peptide independently. For BPC-157 search "BPC-157" or "gastric pentadecapeptide" for landmark papers by Seiwerth, Sikiric, and colleagues. For TB-500 search "TB-500" or "Thymosin beta-4 fragment" for foundational work by Goldstein and others on actin-sequestering activity.
