What is TB-500
TB-500 is a synthetic version of the naturally occurring peptide Thymosin Beta-4 (Tβ4), a protein found in all human cells at particularly high concentrations in platelets and wound fluid. It plays a critical role in cell migration, angiogenesis, and the inflammatory response following injury. Browse the full peptide library for related healing compounds.
Unlike BPC-157 which works more locally around the injection site, TB-500 is a systemic healing peptide that travels throughout the body via the bloodstream, making it effective even when injected far from the injury. This makes it uniquely suited for multiple injuries, widespread inflammation, or systemic recovery needs.
Athletes have used TB-500 extensively for accelerating recovery from muscle tears, tendon injuries, and chronic overuse injuries. For skin-specific healing, consider combining with GHK-Cu. For gut inflammation alongside systemic healing, KPV can be run concurrently. TB-500 is also studied for cardiac repair, wound healing, and has generated interest for its potential hair regrowth effects.
How it works
Actin Regulation: TB-500's primary mechanism is binding to actin (G-actin), a protein critical to cell structure and movement. This promotes cell migration to injury sites — the first step in healing.
Angiogenesis: Like BPC-157, TB-500 promotes the formation of new blood vessels, improving delivery of oxygen and nutrients to damaged tissue.
Anti-Inflammatory: TB-500 modulates inflammation by downregulating inflammatory cytokines and promoting an anti-inflammatory environment at injury sites.
Stem Cell Activation: TB-500 activates progenitor cells (stem-cell-like cells) that differentiate into muscle, nerve, and connective tissue, enabling true tissue regeneration rather than just scar formation.

Dosing protocol
| Phase | Dose | Frequency | Duration |
|---|---|---|---|
| Loading Phase | 5–10mg | 2x per week | Weeks 1–4 |
| Maintenance | 2.5–5mg | Once weekly | Weeks 5–12 |
| Injury Protocol | 5mg | 2x per week | 4–6 weeks |
Always start at the lowest effective dose and titrate up gradually.
Side effects
Common
- Fatigue or lethargy (common in first 1–2 weeks, resolves)
- Mild headache
- Injection site reactions
- Temporary head rush or lightheadedness
Rare
- ·Tumor growth promotion (theoretical concern — avoid with active cancer)
- ·Flushing
- ·Nausea at high doses
Who should not use TB-500
What to expect
Week 1–2
Some users feel fatigue as the immune and inflammatory systems respond. Acute inflammation at injury sites may temporarily increase then resolve.
Week 2–4
Noticeable improvement in pain and mobility. Stiffness reduces. Many report injuries healing faster than any previous protocol.
Week 4–8
Significant tissue repair. Users typically transition to maintenance dosing. Energy and performance improve as systemic inflammation drops.
Month 3+
Most complete their cycle. Hair regrowth users may start to notice early effects around month 3.
FAQ
What is the difference between TB-500 and BPC-157?
BPC-157 is more locally-acting (most effective near the injury) and is particularly strong for gut healing. TB-500 is systemic — it travels throughout the body and is better for widespread inflammation, multiple injuries, or when you cannot inject near the injury. The BPC-157 + TB-500 stack combines both mechanisms.
Does TB-500 really grow hair?
Thymosin Beta-4 has been studied for hair regrowth and activates hair follicle stem cells. Anecdotal reports from users suggest noticeable regrowth when used consistently for 3+ months. Results are modest and individual. It is not a replacement for proven hair loss treatments.
Can I inject TB-500 in my stomach like other peptides?
Yes. Because TB-500 is systemic, you can inject it anywhere subcutaneously. The belly is the most convenient and commonly used site.

This page is editorial information for adults researching peptide therapy. It is not medical advice, not a prescription, and not an endorsement of any specific product, supplier, or protocol. Side effects can be serious and individual response varies. Talk to a licensed physician — ideally one with peptide-specific clinical experience — before starting any compound, adjusting a dose, or discontinuing therapy.
In the Philippines, GLP-1 medications are prescription-only under FDA Philippines regulation. Research-grade peptides occupy a regulatory gray area: import for personal research use is generally tolerated, but the Bureau of Customs reserves the right to inspect and detain shipments. Do not import for resale.
