Nutrastop | MHN Arez Clear Pre | 20 Servings

MHN | Arez Clear | Gym God Pre is a moderate-stim, pump-forward pre-workout built around three priorities: blood flow, muscular endurance, and central drive. The formulation strategy is easy to see from the label. Instead of relying on one giant stimulant payload, Nutrastop built this around a visible pump base of L-citrulline and HydroPrime®, a proven endurance dose of beta-alanine, and a layered nootropic-stimulant system using L-tyrosine, choline bitartrate, Dynamine®, TeaCrine®, synephrine HCl, and Cocobuterol®. The result is a formula designed to feel aggressive in the gym without being one-dimensional.

The pump foundation starts with 5,000mg L-citrulline. Clinically, citrulline is most often studied in the 6-8g range, so 5g sits just under the classic full clinical benchmark but still firmly in the effective range for elevating arginine, increasing nitric oxide production, and supporting vasodilation. Citrulline works by bypassing hepatic first-pass metabolism and converting to arginine in the kidneys, which then feeds endothelial nitric oxide synthase. In practice, that means better blood flow, stronger muscle fullness, and often a more sustained pump than lower-dose 3g formulas. HydroPrime® at 1,500mg strengthens that effect from a different angle. This patented 65% glycerol powder acts as an osmolyte, pulling and retaining water in plasma and muscle tissue to support hyperhydration, cell volumization, and heat tolerance. At 1.5g, it sits within the researched pre-workout range and makes sense alongside citrulline and electrolytes.

Beta-alanine is dosed at 3,200mg, which is the evidence-based daily target used to increase intramuscular carnosine over time. That matters because carnosine buffers exercise-induced hydrogen ions, helping delay the burn that forces you to shut a set down. This is not an acute “feel it instantly” ingredient in terms of performance output, although some users will notice the classic tingling sensation. The real payoff comes with daily use over multiple weeks.

For focus and output, the formula uses 1,000mg L-tyrosine and 1,000mg choline bitartrate. Tyrosine is the precursor to dopamine, norepinephrine, and epinephrine, making it especially useful under stress, fatigue, and high training demand. Choline bitartrate contributes substrate for acetylcholine production, which supports neuromuscular signaling and concentration, though it is less efficient per milligram than more advanced choline donors like citicoline or alpha-GPC. Still, at 1g, it is a meaningful inclusion.

The stimulant architecture is unusually layered. Dynamine® at 100mg and TeaCrine® at 100mg provide methylurate-based stimulation geared toward rapid onset, motivation, and cleaner perceived energy. Both are best known for their synergy with caffeine, but they also contribute stand-alone uplift and focus. Synephrine HCl at 40mg pushes the formula further into thermogenic-performance territory by stimulating adrenergic pathways linked to alertness and fat mobilization. Cocobuterol® at 20mg adds cacao-derived alkaloids and polyphenols that support cAMP signaling and endothelial function, but this dose is below the more robust 50-100mg range typically associated with stronger standalone effects. Niacin at 24mg and the light sodium/chloride electrolyte support round out circulation and hydration support.

The synergy is the story here: citrulline expands blood vessels, HydroPrime® increases fluid retention and volumization, sodium and chloride help hold fluid where it matters, beta-alanine improves repeated-effort tolerance, and the tyrosine-choline-Dynamine®-TeaCrine®-synephrine stack sharpens the CNS side of training. Importantly, this is a fully disclosed label with no proprietary blends, which is a major trust advantage in a category still crowded with hidden-dose stim matrices.

What to expect: day one brings a noticeable shift in focus, drive, pump quality, and likely beta-alanine tingles. Over 2-4 weeks of daily use, the beta-alanine component becomes more valuable as muscle carnosine builds, making hard sets feel more repeatable and less limited by acid accumulation.
