Overview

This pre-workout supplement combines several ingredients known for their ergogenic properties. L-Citrulline and Beta-Alanine are present in effective doses to support nitric oxide production and muscular endurance. The significant amount of caffeine, plus synephrine, will provide a strong stimulant effect. However, some ingredients like Peak O2 and ElevATP require more research to fully validate their performance-enhancing claims. The presence of synephrine adds potential cardiovascular risks that may outweigh its limited benefits.

The Good

Effective Doses of L-Citrulline and Beta-Alanine: Contains clinically relevant doses of L-Citrulline (7000mg) and Beta-Alanine (3200mg), which are beneficial for increasing nitric oxide production and buffering muscle pH, respectively.

Inclusion of Peak O2 and ElevATP: Contains Peak O2 (2000mg) and ElevATP (150mg), which have shown promising results in boosting ATP levels and improving energy production without increasing reactive oxygen species.

Cognitive Enhancement: Contains L-Tyrosine (2000mg), Alpha-GPC (300mg), and Huperzine Serrata (20mg), which may provide cognitive benefits such as improved focus and alertness.

The Bad

High Stimulant Content: Contains a total of 550mg of caffeine from multiple sources plus synephrine, which may cause jitters, anxiety, and increased heart rate in sensitive individuals.

Potential Cardiovascular Risks: Synephrine hydrochloride may increase blood pressure and heart rate, posing risks for individuals with pre-existing cardiovascular conditions.

Risk of Paresthesia: Beta-alanine can cause a harmless but uncomfortable tingling sensation, especially at higher doses.

Is it for you?

Best For: Athletes, bodybuilders, individuals seeking intense workout energy and focus

Skip If: You are sensitive to stimulants, have heart conditions, or are pregnant/nursing.
