Who It's For
Athletes and fitness enthusiasts looking to support their training regimen. Adults who engage in regular intense physical activity and want to support their body's amino acid requirements.
Who It's Not For
Not suitable for individuals with glaucoma, herpes simplex, or those with heart conditions unless prescribed by a physician.
