Where to Buy the Wolverine Stack (BPC-157 + TB-500) in the UK
Wolverine stack is the community nickname for the pairing of BPC-157 and TB-500, the two most co-referenced peptides in soft-tissue research. The name comes from internet forums, not the scientific literature, and no product carries it officially: what a laboratory actually receives is a BPC-157 + TB-500 vial. UK Peptide Lab supplies that pairing as a single co-formulated blend, third-party tested with the certificate published per batch. This guide covers what the nickname refers to, what is in the vial, and what to check before buying it in the UK.
What is the Wolverine stack?
The Wolverine stack refers to BPC-157 and TB-500 supplied together. BPC-157 is a 15-residue pentadecapeptide (1419.53 g/mol, CAS 137525-51-0) derived from a sequence in gastric juice. TB-500 is synthetic thymosin beta-4, a 43-residue polypeptide (4963.4 g/mol, CAS 77591-33-4) whose actin-binding LKKTETQ motif sits at residues 17-23. Worth knowing before comparing suppliers: some UK sellers ship the full 43-residue sequence under the TB-500 label while others ship only a short fragment of it, and different mass splits are sold under the same nickname. UK Peptide Lab's blend contains the full-sequence TB-500 at 5mg alongside BPC-157 at 5mg in one lyophilised vial, with each component identified and assayed separately on the certificate. An equal-mass blend is not equimolar: 5mg of each gives a molar ratio near 3.5:1 in favour of BPC-157. No controlled study has evaluated the two compounds as a combination; their research literatures are separate and largely preclinical. Supplied strictly for in-vitro laboratory research, not for human or veterinary use.
Published research on BPC-157 is indexed on PubMed.
Intended Use: Strictly for in-vitro laboratory research. Not for use in humans or animals. This product has not been evaluated by the MHRA or FDA.

Frequently asked questions about buying Wolverine Stack in the UK
What is the Wolverine stack?
Wolverine stack is the community nickname for BPC-157 and TB-500 supplied together, usually as one co-formulated vial. It is a forum name rather than a scientific term. At UK Peptide Lab the same product is listed as the BPC-157 + TB-500 blend, available as 5mg+5mg and 10mg+10mg lyophilised vials for laboratory research.
Is the Wolverine stack the same as your BPC-157 + TB-500 blend?
Yes. The nickname and the product name describe the same pairing. Our blend contains BPC-157 and full-sequence TB-500 co-formulated in a single vial, with each component assayed separately on the published Certificate of Analysis.
Which TB-500 is in the vial, the fragment or the full sequence?
The full 43-residue thymosin beta-4 sequence, 4963.4 g/mol. Some suppliers sell a short fragment under the same TB-500 name, so check the molecular weight on any certificate before buying: the mass tells you which molecule you are getting.
Is the blend a 1:1 mix?
By mass, yes: 5mg of each component. By moles, no. BPC-157 is 1419.53 g/mol and TB-500 is 4963.4 g/mol, so an equal-mass vial is roughly 3.5:1 BPC-157 to TB-500 in molar terms. Any calculation expressed in moles has to account for that.
Has the BPC-157 and TB-500 combination been studied together?
No controlled study has evaluated this specific combination. Each compound has its own preclinical literature, and they are often run alongside one another in soft-tissue research designs because the reported mechanisms are distinct, but combination-specific data does not exist. We state this plainly rather than implying otherwise.
Is the Wolverine stack legal to buy in the UK?
Yes, BPC-157 and TB-500 are lawful to purchase in the UK for in-vitro laboratory research. Neither is a licensed medicine and neither is sold for human or veterinary use. Both appear on the WADA Prohibited List, which concerns competitive sport rather than laboratory supply. Buyers must be 18 or over and accept research-use-only terms.
What purity is it and is the COA published?
The current 5+5mg blend batch UKPL-2237 has a published Janoshik report linked on the product page before you order. It reports the content of each component separately under the batch number printed on the vial.
How fast is UK delivery?
Orders placed before 3pm UK time on a working day are dispatched same-day from our UK facility via Royal Mail Tracked 24. UK delivery is free on orders over £69.
