The goal of this trial is to find out if Thymus Nuclear Extract is safe and well-tolerated in healthy men and women by testing three different dose levels and comparing the results to a placebo.

This is a 12 to 25 week study (if study participants are willing to follow up on study results) where participants are randomly assigned to groups and neither they nor the researchers know who receives Thymus Nuclear Extract or a placebo. The trial focuses on evaluating the safety of the extract in healthy adults by monitoring for adverse events and conducting safety assessments throughout the study.
