Onnit Labs’ Pre-Workout Formula Increased Strength Gains in Placebo-Controlled Study

January 4, 2016
Updated May 15, 2020

Exercise physiology researchers at the Institute of Sports Science & Medicine at Florida State University investigated Onnit Labs’ pre-workout formula, T+. T+ is a caffeine-free supplement that contains BCAAs, mucuna pruriens, longjack and other earth grown nutrients. Each lot is certified drug free by the Banned Control Substances Group (BSCG).

The researchers studied the effects of T+ on strength, training volume, body composition and hormone levels. The full study results are available in the December 2015 issue of the Journal of Strength and Conditioning Research.

Dr. Michael Ormsbee, Interim Director of Sports Science & Medicine at Florida State University, recruited 32 college-aged athletes with powerlifting experiencing to enter the double-blind, placebo controlled study.

All subjects performed a 1-rep max bench press, squat and deadlift (in accordance with the National Strength and Conditioning Association guidelines) at the beginning of the study and after four weeks of strength training. Blood was analyzed, diets were monitored, and adverse effects were recorded for all subjects.

Results of the Study

Subjects who consumed T+ improved their 1-rep max (RM) bench press over the group who ingested the placebo. Additionally, when the three weights of Olympic lifts were combined, the T+ group again showed a greater improvement than their placebo counterparts, adding 34 kg (75 lbs) from baseline compared to 24 kg (53 lbs) in the placebo group.

An analysis of training volumes revealed that those in the T+ group completed more repetitions to volitional fatigue than the placebo group. The T+ group added a greater number of repetitions per week averaging 120 reps compared to weekly average of 111 for the placebo group. The ability to increase the final number of repetitions until the point of failure, either through reduction of fatigue or elevated volition, likely contributed to the performance improvements observed at the end of the study.

Dr. Michael Ormsbee was encouraged by the acceptance of the study. He commented, “This research provides another stepping stone in the path to identify useful multi-ingredient performance supplements that promote performance improvements for active people and athletes.”

The study concluded that the addition of T+ to a progressive resistance training program resulted in a greater increase in strength in bench press and total weight lifted compared to placebo.

Dr. Ormsbee further stated, “More companies need to understand that having evidence-based data to support their claims is the cornerstone to development in this field.” This study validates the concept that power athletes can enhance the limits of their own performance with high-quality and scientifically tested nutritional formulas such as T+.
