TB-500: Faster Recovery, Better Flexibility
TB-500 is a powerful healing peptide derived from Thymosin Beta-4 - one of the most abundant proteins in the human body. Athletes and active people use it to recover from injuries faster and stay in the game longer.
Quick facts
What is TB-500?
TB-500 is a synthetic peptide derived from Thymosin Beta-4, a protein found naturally in virtually every cell in the human body. Thymosin Beta-4 plays a central role in building new blood vessels, muscle tissue, skin, and connective tissue.
The TB-500 fragment was isolated because it contains most of the healing and anti-inflammatory properties of the full protein - in a form that can be synthesized and administered as a peptide therapy.
The "Wolverine stack": TB-500 is often combined with BPC-157 for dramatically enhanced healing. This combination addresses recovery from multiple angles simultaneously and is one of the most popular injury recovery protocols in peptide therapy.
Key benefits
Tendon & ligament repair
Accelerates healing of torn or damaged tendons and ligaments - injuries that typically take months to recover from.
Improved flexibility
Reduces muscle stiffness and improves range of motion - users often notice this within the first few weeks.
Reduced inflammation
Powerful systemic anti-inflammatory effect, especially in chronic joint pain and overuse injuries.
Muscle repair
Promotes regrowth of damaged muscle fiber and reduces recovery time from intense training.
Cardiac repair
Emerging research shows TB-500 may support heart tissue repair after cardiac events.
New blood vessel growth
Stimulates angiogenesis - routing fresh blood supply into damaged tissue to accelerate healing.
How does TB-500 work?
TB-500's primary mechanism is actin regulation. Actin is a protein that forms the structural framework of cells - it's essential for cell movement, division, and signaling. By binding to actin, TB-500 promotes cell migration into damaged tissue and accelerates the repair process.
Angiogenesis
Like BPC-157, TB-500 stimulates the growth of new blood vessels (angiogenesis) into injured areas. This is critical because healing requires a fresh supply of oxygen and nutrients - and many chronic injuries persist because blood supply to the area is poor.
Systemic vs. local action
One of TB-500's unique features is that it works systemically - meaning it doesn't have to be injected at the injury site to be effective. This makes it easier to administer while still delivering healing benefits to remote areas of the body.
Dosing guide
| Phase | Dose | Frequency | Duration |
|---|---|---|---|
| Loading (acute injury) | 2–2.5 mg | Twice per week | 4–6 weeks |
| Maintenance | 2 mg | Once per week | Ongoing |
| Prevention / performance | 2 mg | Every 2 weeks | Ongoing |
| Stacked with BPC-157 | 2 mg TB-500 + 300 mcg BPC | 2x/week | 4–8 weeks |
Note: Dosing should be supervised by a licensed provider. TB-500 is typically injected subcutaneously (under the skin) anywhere on the body - it does not need to be injected directly at the injury site.
Side effects & safety
TB-500 has a strong safety profile with minimal reported side effects. The most common are mild injection site reactions - redness, swelling, or itching - which typically resolve quickly.
Some users report a temporary head rush or lightheadedness immediately after injection. This is harmless and passes within minutes. No serious adverse effects have been documented in the literature.
