Congratulations to Proper Wild for completing their clinical trial with Citruslabs

A Clinical Trial to Assess the Efficacy of a Plant-based Energy Shot on Focus and ADHD-like Symptoms

Many people struggle with ADHD-like symptoms, such as difficulty staying focused, controlling their impulses, and attention deficits. Research has suggested that combining Caffeine and L-Theanine can reduce jitters, heighten concentration and cognitive alertness, while also acting as a mood booster. Proper Wild has created an all-natural energy shot containing these active ingredients. In addition, Proper Wild contains organic caffeine from green tea and L-Theanine (a naturally occurring amino acid also found in Green Tea) derived from green tea.


To test the efficacy of their energy shot drink, Proper Wild decided to enroll in a clinical trial with Citruslabs.
