Peptides studied for injury recovery (UK research overview)
The peptides repeatedly named in tissue-protection and regeneration literature are BPC-157 and TB-500. Both sit in the research-use lane in the UK. No human RCTs are published in either compound. This page is research commentary, not medical advice.
Tendon, ligament, and gut-lining injuries are slow-healing tissues. Standard of care in the UK is rest, physiotherapy, anti-inflammatories where appropriate, and time. There is no approved peptide medication for ligament or tendon healing on the NHS or in private practice.
Two peptides appear repeatedly in the preclinical injury-recovery literature: BPC-157 and TB-500 (Thymosin Beta-4 fragment). Both are research compounds. Neither has completed phase III human trials. Both are sold in the UK under research-use-only framing by the retailers indexed below.
BPC-157 is a 15-amino-acid sequence derived from a protein found in human gastric juice. Preclinical literature (animal models, mostly rodents) reports tissue-protective effects across tendon, gut lining, nerve, and blood vessel. The body of work is large but almost entirely non-human. No human RCT data is published. UK research peptide retailers stock BPC-157 in 5mg vials typically priced from around £14 to £20 per vial.
TB-500 is a synthetic fragment of Thymosin Beta-4, a naturally occurring 43-amino-acid protein. Preclinical literature reports actin-binding and cell-migration effects relevant to wound healing and cardiac repair. As with BPC-157, the human evidence base is thin. Stocked across most UK research peptide retailers, typically 5mg vials priced from around £30 to £42.
Many UK retailers sell BPC-157 and TB-500 together as a named stack (Wolverine Stack is the most common branding). Stack pricing is usually 5 to 10 percent below the sum of single-vial prices. We index these stacks across retailers in our Stack Comparison pages.
If you are working with a sports doctor or physiotherapist, peptides are a research-tier conversation. UK clinical practice does not currently include them in recovery protocols. This page exists to map the research lane that exists alongside the clinical lane, with explicit CoA transparency on every retailer surfaced.

Frequently asked questions
Is BPC-157 legal in the UK?
BPC-157 is not an approved medicine in the UK. It is sold under research-use-only framing by UK research peptide retailers. It is not licensed for human use and is not prescribed in NHS or private clinical practice.
Do UK clinics prescribe BPC-157 or TB-500?
No. Neither compound is a licensed UK medicine. Mainstream UK clinical practice does not include peptide prescribing for injury recovery outside of approved medications such as Tesamorelin in specific contexts.
What is a Wolverine Stack?
A retailer-branded bundle of BPC-157 and TB-500 sold together. The name was coined by US peptide retailers and has spread to UK suppliers. Pricing is typically 5 to 10 percent below buying both vials separately. We track stack pricing across UK retailers on our Stack Comparison pages.
How do I check a retailer is publishing real Certificates of Analysis?
See our CoA Trust Index. We tier every UK retailer on whether CoAs are per-batch, openly published or gated, third-party verifiable, and from a named laboratory. Three UK retailers reach the green tier as of the last review.
What is the difference between BPC-157 oral capsules and injectable vials?
Most UK research stocking is the injectable lyophilised form (5mg vials, reconstituted with bacteriostatic water). A small number of retailers offer oral capsule forms. The animal-model literature is dominated by injectable administration; oral bioavailability is a separate research question and not strongly supported in the published preclinical work.
