Clinical insights

Key research benefits

A 28-amino-acid thymic peptide approved in 35+ countries (as Zadaxin) for chronic hepatitis and as a cancer-therapy adjunct — one of the most studied peptides in this guide.

  • 86% viral DNA clearance vs. 20% with placebo in a controlled hepatitis B trial.
  • Cut flu incidence from 19% to 6% in a 90-patient elderly trial while boosting vaccine antibody response.
  • Cancer adjunct data linked to a median survival of 38.4 months vs. 8 months when added to checkpoint-inhibitor therapy in a melanoma trial.

Research backing

Over 11,000 human subjects across 30+ trials — the deepest human evidence base in this guide. Note: the large 2025 BMJ TESTS sepsis trial (n=1,089) found no mortality benefit, illustrating that effect sizes shrink in the largest, highest-quality trials.
