TB-500
Also known as: Thymosin beta-4 fragment
A lab-made piece of thymosin beta-4, a natural protein that helps cells move toward damaged tissue and rebuild it.

- Category
- Recovery & tissue support
- FDA status
- Not FDA-approved
Overview
What it is
TB-500 is a lab-made copy of a short section of thymosin beta-4, a protein found in nearly every tissue in the body. That protein helps cells move to where they are needed during repair.
TB-500 copies a seven-amino-acid stretch of thymosin beta-4. That protein turns up in nearly every tissue, and levels are highest in blood platelets and in wound fluid.
Interest grew because that protein shows up early wherever the body is repairing itself. The full protein has been tested in human trials for wounds and eye conditions; TB-500 is the short fragment, and it has not.
Clinics usually group it with BPC-157. The two get discussed together so often that people assume they are related, but they come from different proteins.
Benefits
What it supports
- Supports repair in muscle, tendon, ligament, and other connective tissue
- Supports a balanced inflammatory response while tissue rebuilds
- Supports a steady return to training after a strain
- Supports flexibility, joint comfort, and mobility goals
Mechanism
How it works
1
Repair depends on cells physically moving to where the damage is. Thymosin beta-4 helps that happen by binding actin, the protein filament cells use to change shape and crawl.
2
By keeping a pool of actin available, the protein makes it easier for repair cells to migrate into damaged tissue and start rebuilding.
3
Animal research also points to new blood vessel growth, collagen laid into healing tissue, and a calmer inflammatory response.
4
TB-500 is the fragment thought to carry most of that activity. The evidence sits in animals and cell cultures, not in human trials.
Context
Who it's for
Active adults dealing with tendon, ligament, or muscle soreness after training
People recovering from a soft-tissue strain who want to understand the biology first
Adults focused on flexibility, mobility, and getting back to activity

TB-500 FAQ
Good to know
Regulatory & considerations
TB-500 is not FDA-approved. That means the FDA has not reviewed it for safety or effectiveness for the uses described here. Its healing research is largely in animals, and it is banned by anti-doping organizations.
Peptides in our shop are sourced from US-licensed manufacturers.
TB-500 is not FDA-approved, and its status under pharmacy compounding rules is still being decided.
It is banned by anti-doping organizations, so athletes in tested sport should know it can trigger a positive test.
Because it encourages new blood vessel growth, anyone with a history of cancer should raise that before any conversation goes further.
TB-500 and BPC-157 come from different proteins. Being mentioned together does not make them substitutes.
