Shroom Tech Sport is Onnit's stimulant-free pre-workout supplement featuring Cordyceps Sinensis mushrooms, which are traditionally used to support cellular energy (ATP) and oxygen utilization.

Unlike typical pre-workouts loaded with caffeine and other stimulants, this gives you sustained energy and endurance without the jitters or crash.

The formula also includes adaptogens like Rhodiola Rosea and Ashwagandha to help your body handle stress, plus Chromium Picolinate for blood sugar support. Users report being able to train harder, recover faster between sets, and experience less soreness after workouts.

It's certified drug-free by the Banned Substances Control Group, making it safe for competitive athletes. Best for endurance activities.
