About:
The full-length actin-binding peptide from which TB-500 is derived, studied for wound and corneal healing.
What does this peptide do?
Backed by human trial data, narrower than the strongest evidence. Research focuses on wound healing and corneal healing.
Wound healing
The full-length peptide studied for wound healing.
Corneal healing
Also studied for corneal healing.
Evidence grade
BHighest evidence grade among the graded claims: B. Grades reflect study strength, not benefit.
What are the benefits and side effects of this peptide
What research says it may help with
- Thymosin beta-4 is the full-length peptide from which TB-500 is derived, and it has more human evidence: randomized trials in corneal repair and a cardiac cell-therapy study.
- The injectable research market sells the fragment, not this.
Who should avoid it
- People who are pregnant or breastfeeding
- Children and adolescents
- People with active or prior cancer, since tissue-repair signalling is not characterised for safety here
- Known hypersensitivity to peptide preparations
See the safety section. Absence of a flag is not evidence of safety.
A grade reflects evidence strength, not a recommendation to use this compound; a strong grade can attach to a harmful effect.
How to store this peptide
Typically sold as a lyophilized powder. Reconstituted solutions are perishable, need refrigeration, and require clean handling to avoid contamination.
Lyophilized storage
Store at −20 °C, protected from light.
Reconstituted storage
Keep at 2–8 °C and use within a short period. For longer storage, aliquot and freeze at −20 °C.
Storage Handling
Avoid repeated freeze–thaw cycles. Let the vial reach room temperature before opening.
