Description (short sentences, Grade 9 target, ~280 words)

TB-500 10mg and 20mg: A Thymosin Beta-4 Research Peptide

TB-500 comes from Thymosin Beta-4. The full peptide has 43 amino acids. Scientists first found it in calf thymus tissue back in the 1960s. TB-500 covers the active part of that bigger peptide.

Quick Facts

Name: TB-500
Full name: Thymosin Beta-4 fragment
Formula: C212H350N56O78S
Weight: about 4,963.4 g/mol
CAS number: 77591-33-4
Look: White to off white powder, freeze dried

Why Researchers Use It

TB-500 has a part called the actin binding domain. Actin is a key structural protein in cells. This domain lets the peptide interact with actin in lab studies. The full peptide stays unstructured in solution. It doesn't fold into one fixed shape, which gives it flexibility during binding studies.

What Labs Study It For

Researchers use TB-500 to look at:

Actin binding and sequestration
Cell migration patterns
Tissue repair signaling, in vitro
Cytoskeletal organization
Structure activity work on Thymosin Beta-4 fragments

Some labs also pair TB-500 with PT-141, especially when comparing different receptor and structural peptide research side by side.

Regulatory Status

The FDA hasn't approved TB-500 for treating or preventing anything. It's sold strictly for lab research.

Legal and Safety Info

Not a supplement, just a raw research compound. Keep away from kids. Long term safety data is limited, so only trained lab personnel should handle this.

Buying this means agreeing to use it legally, for research only.
