Maximum Human Performance STRONG AF is a pre-workout supplement for high-intensity strength training, with 5 g creatine monohydrate and 400 mg caffeine per serving to support strength, energy and focus.
STRONG AF is made for athletes whose sessions involve demanding sets, high effort and a focus on strength or powerlifting. Its ingredient blend addresses several parts of training at once, including ATP production, fatigue buffering, muscle pumps, focus and recovery. The formula combines performance ingredients with a stimulant, making it suited to pre-workout use rather than a general food or hydration product.
STRONG AF combines creatine monohydrate, Shilajit and Alpha-GPC to support ATP availability, mitochondrial respiration and muscle motor-neuron activation. Creatine is included to help regenerate ATP during high-intensity efforts and to support lean mass through cellular hydration and protein synthesis; the formula also connects it with recovery. Alpha-GPC supplies choline for acetylcholine synthesis, a pathway associated in the formula rationale with focus and power output. The Shilajit and Alpha-GPC combination is also intended to support testosterone and lower cortisol as part of hormonal regulation.
STRONG AF uses citrulline malate and beta-alanine to support blood flow and muscular endurance during training. L-citrulline converts to L-arginine, which supports nitric oxide production and muscle pumps; the malate component supports the Krebs cycle and ATP production. Beta-alanine supports carnosine levels, while the formula’s fatigue-buffering approach is intended to help maintain performance during hard efforts.
STRONG AF combines Alpha-GPC, DMAE and caffeine for workout focus, alertness and motivation. Alpha-GPC supports acetylcholine synthesis; DMAE is included for alertness, mood, motivation and pre-workout focus. Caffeine acts as an adenosine receptor antagonist and is included to support alertness, motivation and fat oxidation.
STRONG AF is suited to strength athletes and powerlifters looking for a pre-workout formula that combines strength, endurance, focus and energy ingredients in one serving. Its blend pairs creatine and performance-focused amino acids with Alpha-GPC, Shilajit, DMAE, caffeine and electrolytes, making it a fit for high-intensity training goals.
