TISSUE REPAIR · RESEARCH USE ONLY
Wolverine — pre-paired research blend of BPC-157 and TB-500 (Thymosin β-4 fragment), studied in tissue-pathway research.
Compound identity
- Compound A: BPC-157 (Body Protection Compound) — pentadecapeptide · CAS 137525-51-0
- Compound B: TB-500 — synthetic fragment of Thymosin β-4 · CAS 77591-33-4
- Class: Synthetic peptide blend, tissue-pathway research compound
- Mechanism (in vitro): BPC-157 has been studied for activity in angiogenic and growth-factor signaling pathways; TB-500 (Tβ4 fragment) is studied for actin-binding and cell-migration pathway activity
Research context
The "Wolverine" pairing is studied as a tissue-repair pathway research blend. Published research has examined BPC-157 in gastric-mucosa, vascular, and tendon model studies, and TB-500 in cell-migration and angiogenesis model studies.

RECONSTITUTION & RESEARCH PROTOCOLS
Preclinical literature onlyResearch protocol intensities, summarized from published literature. The math is computed for the vial size you pick. Not a dosing recommendation.
Both components are preclinical only. The blend itself has no published research — protocols are derived from component-level literature scaled to the combined formulation.
Reference research protocols from published peer-reviewed studies. Each card cites its source. This calculator is not a dosing recommendation. For research use only. Selection of any specific protocol is the responsibility of the qualified investigator under appropriate institutional oversight.
RECONSTITUTION & STORAGE PROTOCOL
Procedure
- Allow vial to equilibrate to room temperature before reconstitution.
- Inject solvent slowly along the inner wall of the vial.
- Gently swirl until fully dissolved.
- Resulting solution should be clear and colorless.
Storage & stability
| Lyophilized | ≥24 months at -20°C, light-protected, sealed. |
| Reconstituted | 30 days at 2-8°C in original vial. |
For research use only. Protocol values are derived from established laboratory practice and published peptide handling literature. Specific experimental designs may require alternative reconstitution parameters.

RESEARCH FAQ
Common research questions.
How do you verify peptide purity?
Every batch is tested by an independent third-party laboratory using High-Performance Liquid Chromatography (HPLC) for purity quantification and mass spectrometry for structural identity. Lots that don't clear our 99% purity floor are not released. The full Certificate of Analysis is published on each product page.
Where is the Certificate of Analysis (COA) for the lot I'd receive?
Each product page links to the COA for the current shipping batch. After purchase, the COA for your specific lot is permanently attached to your order record. Past COAs are also accessible via your account.
How should I store the compounds when they arrive?
Lyophilized peptides are stored at –20°C, away from light. Storage protocols vary by compound; consult product COA. Materials supplied for in-vitro research only.
How fast do orders ship?
Orders placed before 2pm EST ship the same day from our US-based facility. Temperature-sensitive compounds ship in cold-chain insulated packaging with gel packs. Tracking is provided via email.
Are these products approved for human or veterinary use?
No. All products sold by Merit Peptides are intended strictly for laboratory and scientific research use only. They have not been evaluated by the U.S. Food and Drug Administration and are not for human consumption, veterinary use, or any therapeutic application.
What are your bulk and volume pricing tiers?
Tiered discounts apply automatically at checkout: 10% off when you order 3 or more of any compound, 15% off on orders of 6 or more, and 20% off on orders of 12 or more. No coupon code required.
Are your products manufactured in the US?
Yes. All Merit Peptides compounds are synthesized and formulated in independently audited US laboratories with full toxicity and heavy-metal panels per batch. Our manufacturing partners follow current Good Manufacturing Practice (cGMP) guidelines.
What if my compound arrives damaged or my COA doesn't match?
Contact info@meritpeptides.com within 7 days. We'll replace the compound or refund the order. Every shipment is matched to the COA on file before it leaves the facility.
