TB-500 is a synthetic peptide based on Thymosin Beta-4, studied for systemic (body-wide) tissue repair, flexibility, and recovery from stubborn injuries. At Ivologist it is available by prescription after a telehealth consultation and dispensed through licensed compounding pharmacies. TB-500 is not FDA-approved.

In mostly animal and lab research, TB-500 is studied for cell migration and tissue remodeling throughout the body, not just at one site. Human evidence is limited.
Early, mostly preclinical research suggests TB-500 may support flexibility and help reduce adhesions and scar-related stiffness.
Licensed providers determine dosing, frequency, and duration based on medical history and clinical evaluation.
TB-500 is often paired with BPC-157; the pairing itself has not been studied, and your provider decides whether either suits you.
When clinically appropriate, TB-500 may be coordinated alongside recovery, longevity, or hormone programs.
All treatment plans require medical evaluation and approval. Individual results may vary.

Understanding Tissue Repair and TB-500
Tissue repair capacity naturally changes with age and injury. Learn how clinician-guided TB-500 therapy may support systemic repair, flexibility, and recovery.
Understanding Tissue Repair
Learn about TB-500, how it works, and how clinician-guided therapy may support your recovery goals.
The Physiology
Proposed Tissue-Repair Pathway
Injury → Cell migration → Angiogenesis → Tissue remodeling
In lab and animal studies, TB-500 upregulates actin, helping cells migrate to areas of injury, and is linked to new blood-vessel formation. In that research its effects were studied body-wide rather than at one site. How it works in people is still being researched.
With age and repeated strain, the body's repair response can slow, which may affect recovery and flexibility.

Experiencing multiple patterns may warrant clinician evaluation.
Who Is It For?
Who May Benefit from TB-500?
TB-500 may be considered for adults who are:
Clinical evaluation is required. Your eligibility will be determined by a licensed provider.
TB-500 vs BPC-157
TB-500 vs BPC-157
How the research on each differs. Both are early: mostly animal and lab studies.
TB-500
Studied for body-wide repair (mostly animal research).
- Animal studies: cell migration and tissue remodeling
- Studied for broad or hard-to-reach injury
- Human evidence: very limited
BPC-157
Studied mainly for repair at the injury site (animal research).
- •Animal studies: tendon, ligament and gut healing
- •Effects studied mainly near the injury site
- •Human evidence: very limited
The two are often discussed together as the "Wolverine" pairing; the pairing itself has not been studied. Treatment decisions are determined through clinician evaluation.
Protocol
Protocol Philosophy
TB-500 is studied for supporting the body's own repair processes, so any response tends to build gradually.
An example, not your plan. This page offers injectable TB-500 only. The 12-week cycle you choose is the program: clinician consultation, peptide medication and free shipping; labs may be required. It is not a dosing schedule; your provider decides your dose, how often and for how long.
Start (Weeks 1–2)
Injections begin as your provider prescribes, often more frequently at first.
Build (Weeks 3–6)
Some people report changes in comfort, mobility or recovery. This is not guaranteed.
Review (Weeks 6–8)
Your provider assesses your response; frequency may step down.
End of cycle (Weeks 10–12)
Your provider decides whether to stop, pause or continue.
Responses vary by individual.
Research Findings and Limits
Research Findings and Limits
What TB-500 has been studied for, and the kind of study behind each:
Limits of the research. Most TB-500 research is preclinical (lab and animal studies). Human evidence is very limited, and no outcome is guaranteed.
Individual responses vary.
Designed for Safety. Guided by Clinicians.
- Not for performance enhancement — TB-500 is prescribed for recovery and soft-tissue repair under clinical supervision, not for athletic advantage
- Gradual, not instant — any response builds over weeks and is not guaranteed; a brief head-rush or transient fatigue after dosing is the commonly reported effect
- Recommendations are based on your history, medications and clinical findings
TB-500 is screened for contraindications (active or recent cancer, pregnancy and breastfeeding), and blood-pressure medicines are reviewed at intake

Frequently Asked Questions
Get answers to commonly asked questions.
TB-500 is a synthetic version of Thymosin Beta-4, a protein involved in cell migration and tissue repair. It is studied as a systemic regenerative peptide and is available as a compounded prescription medication.
It is studied for systemic soft-tissue, tendon, and ligament repair, flexibility, reduced adhesions, and chronic slow-healing injuries — used within a supervised recovery program, not as a standalone cure.
No. TB-500 is not FDA-approved. It is compounded by licensed 503A pharmacies and prescribed individually after a medical evaluation.
In lab and animal studies, TB-500 upregulates actin, helping cells migrate to injured areas. That research links it to angiogenesis, tissue remodeling, and reduced inflammation across the body rather than at one site; how it works in people is still being researched.
In mostly animal research, TB-500 has been studied for body-wide repair and BPC-157 for repair near a specific injury. They are often paired, the basis of Ivologist's Wolverine Stack, though the pairing itself has not been studied.
