Other ingredients in the Performance category.
Agmatine Sulfate
Arginine metabolite with nitric oxide and pain-modulating effects. Enhances pumps.
Arachidonic Acid (ARA)
Omega-6 fatty acid that amplifies exercise-induced muscle signaling. Increases training response but also inflammation.
BCAAs
A branched-chain amino acid blend in a 2:1:1 leucine-to-isoleucine-to-valine ratio, formulated in instantized (micronized) form for improved solubility. BCAAs support muscle protein synthesis and may reduce exercise-induced fatigue, though whole protein sources provide comparable benefits at lower cost.
Beetroot / Nitrates
Dietary nitrates converted to nitric oxide for improved endurance and blood flow. Can enhance exercise efficiency.
Beta-Alanine
Increases muscle carnosine for buffering acid during high-intensity exercise. Delays fatigue in 1-4 minute efforts.
Beta-Hydroxybutyrate (BHB)
Exogenous ketone body that can elevate blood ketone levels. Used for energy, cognitive function, and supporting ketogenic diets.
