About Skin Health

Improvement of skin texture, tone, and overall appearance.

Research Evidence

Animal studies show significant wound healing acceleration, cardiac tissue repair, and anti-inflammatory effects. Note: Phase 2 human trials exist for full Thymosin Beta-4 protein (not TB-500 specifically) - 73-patient venous stasis ulcer trial showed ~25% achieved complete healing at 3 months. Ophthalmologic trials for dry eye also completed. However, TB-500 fragment itself has no human clinical trials. FDA restricted TB-500 from compounding under Category 2. WADA prohibited at all times.

Clinical Status:Preclinical - No human clinical trials. FDA Category 2 (pending reclassification to Category 1 per April 15, 2026 HHS announcement; remains Category 2 under current law until formal FDA rule; PCAC review July 23-24, 2026)
