TB-500 is a synthetic peptide version of the naturally occurring Thymosin Beta 4 (TB4), a vital cellular constituent in many tissues.

Thymosin Beta 4 is present in almost all the body cells of mammals, and it functions as a healing protein.

Research using TB-500 in animal studies showed it might benefit wound healing, muscle repair, and joint and tissue strength.

At Loti Labs, we pride ourselves on stocking high-quality research chemicals. Buy TB-500 for sale for research purposes only and not for human consumption. It is available in lyophilized powder form and sold in 5 mg vials.

TB500 is a peptide involved in complex regulatory and developmental processes in vivo. It appears to be a viable component of tissue regeneration, cell differentiation, and inflammation.

According to the studies, TB500 is effective for angiogenesis (development of new blood vessels) and the development and differentiation of new cells. It also causes the migration of the newly formed cells.


CAS Number: 885340-08-9

Molar Mass: 889.01g/mol

Molecular Formula: C38H68N10 O14


In animal research, TB500 exerted its effect on animals by binding to actin, a cell-building protein. It attaches to actin which helps to promote cell migration and proliferation. As a result, healing and recovery are achieved as new blood vessels form.

Also, TB500 can travel a long distance in the body because of its unique molecular structure.

Therefore, systemic effects help both local and distant site injury, including reduced inflammation and optimizing flexibility.


The therapeutic effects of the TB500 are demonstrated in some animal studies by:

  • Faster wound healing
  • Enhanced Recovery
  • Muscle and strength gain with improved flexibility
  • Tissue repair and regeneration
  • Protection against injury
  • Reduced inflammation


On the whole TB500 administered in animal research exhibited minimal side effects.

Most of the side effects observed are similar to those observed with other peptides which include:

  • Lightheadedness 
  • Nausea
  • Extreme fatigue
  • Headache
