Creatine Monohydrate – The Gold Standard for Strength and Hypertrophy

Creatine monohydrate is the most rigorously researched ergogenic aid in sports science history. By elevating intramuscular phosphocreatine reserves, it accelerates rapid ATP regeneration during maximal efforts. Consistent daily dosing of 3-5 g produces 5-15% strength gains and accelerated lean mass accumulation.

Whey Protein (WPC / WPI) – Maximizing Muscle Protein Synthesis

Whey protein boasts superior biological value and a concentrated abundance of leucine – the primary branched-chain amino acid that triggers the intracellular mTOR complex. Consuming 25-30 g post-workout provides the maximal molecular stimulus for myofibrillar protein synthesis.

Beta-Alanine – Intracellular Buffering and Muscular Endurance

Beta-alanine binds with histidine to synthesize muscle carnosine, the primary intracellular buffer counteracting exercise-induced acidosis. Supplementing 3.2-6.4 g daily enables an extra 1-2 reps during grueling sets lasting 60 to 240 seconds, progressively amplifying training volume.

Electrolytes and Peri-Workout Carbohydrates – Cellular Hydration

A modest 2% reduction in muscular hydration attenuates peak force output by up to 10-15%. Formulating workout fluids with sodium, potassium, and rapid-clearing carbohydrates (such as highly branched cyclic dextrin) sustains cellular osmotic pressure, glycogen retention, and muscle pumps.

The Third Mass XXL

The Third Mass XXL by Trec is a nearly 270 calorie serving derived from a high-grade concentrate of whey protein and a mixture of carbohydrates (maltodextrin and dextrose). It also contains a complex of B-vitamins, which perform many important functions for the body, such as reducing fatigue, supporting proper protein and glycogen metabolism, or affecting hormonal activity.
