TB-500

Synthetic fragment of Thymosin Beta-4 for systemic recovery.

Recovery & Injury Muscle & Growth

01 · Overview

What it actually is

TB-500 is a synthetic fragment of Thymosin Beta-4, one of the most abundant proteins in human cells and a master regulator of actin — the protein that lets cells move. Where BPC-157 works locally to drive blood vessels into a specific injury, TB-500 works systemically to help cells migrate to wherever they're needed.

It was originally developed with veterinary and equine use in mind (it's still widely used on racehorses), and the human research pipeline focuses on cardiac repair after heart attack and corneal healing.

02 · Fit

Who this is for

People with systemic wear-and-tear, chronic tightness, or multiple overlapping injuries — often paired with BPC-157.

03 · Mechanism

How it works

TB-500 upregulates actin binding, promotes cell migration, and drives new blood vessel formation for full-body tissue regeneration.

Documented effects

→Systemic recovery from soft tissue injury
→Improved flexibility and reduced adhesion
→Cardiac and vascular protective activity
→Synergy with BPC-157 for repair stacks

04 · Use cases

Common uses

·Multiple overlapping soft-tissue injuries
·Chronic tightness and reduced range of motion
·Post-surgical recovery
·Systemic athletic recovery during hard training blocks

05 · Protocols

Cycle guidance clinicians commonly outline

Reference protocols paraphrased from published research and common clinical practice. Individual response varies. Work with a qualified provider before running anything below.

Loading phase

Protocol

2–2.5mg subcutaneous twice weekly (e.g. Monday + Thursday)

Duration

4–6 weeks

Notes

The higher upfront dose saturates tissues. Location of the injection matters less than for BPC-157.

Maintenance

Protocol

2mg subcutaneous once weekly

Duration

4–8 weeks after loading

Notes

Enough to keep systemic effects going without loading-phase cost.

Baseline reconstitution

Reconstitute 10mg with 2ml BAC water for 5mg/ml.

06 · Combinations

Stacking notes

Almost always paired with BPC-157 — BPC handles local angiogenesis, TB-500 handles systemic cell migration. Add GHK-Cu for scar quality, or sermorelin/tesamorelin if training-related connective tissue recovery is the focus.

07 · Safety

Side effects & contraindications

Commonly reported effects

·Temporary lethargy for a day or two after loading doses
·Mild head-rush or flushing shortly after injection
·Injection-site tenderness

Talk to a doctor first

·Active cancer (promotes angiogenesis and cell migration)
·Pregnancy and breastfeeding
·Banned in-competition by WADA — do not use if you're a tested athlete

08 · Trivia

Fun facts

01The parent protein Thymosin Beta-4 is one of the top 3 most abundant proteins in most cells.
02It's used widely in racehorse recovery — the equine market is bigger than the human market.
03It played a role in early cardiac-repair research after heart attack.
04It's called TB-500, but it's actually a shorter fragment of the full TB-4 protein.

09 · FAQ

Common questions

Why do I need a loading phase?+

TB-500 works by saturating tissues so cells can migrate freely. The loading phase builds that reservoir. Skipping it delays results.

Can I use it alone without BPC-157?+

Yes, but most users find the combination noticeably better for injuries. Alone, it's still useful for systemic tightness and general recovery.
