PURE Stim Pre-Workout

Tired of Double-Scooping Pre-Workouts Just to Feel the Effects?

Say goodbye to overdosing and underperforming. Pure Nutrition’s PURE Stim Pre-Workout is a scientifically formulated, evidence-based supplement featuring clinically effective doses of proven ergogenic ingredients — all at an affordable price.

Unlike many pre-workouts that rely on filler ingredients and flashy labels, PURE Stim delivers exactly what your body needs for real results — and nothing you don’t. Each ingredient was selected based on peer-reviewed research and quality, two critical factors often ignored in today’s supplement market.

Key Benefits of PURE Stim Pre-Workout

Clinically Dosed for Maximum Performance:
PURE Stim provides full clinical servings of key performance-enhancing ingredients, avoiding under-dosed blends and unnecessary additives.

Enhances Strength, Endurance, and Muscle Pumps:
With research-backed nitric oxide boosters and proven ergogenic aids, PURE Stim increases blood flow, muscular endurance, and overall workout capacity — starting with your first scoop.

Clean, Sustained Energy with Natural Caffeine:
Powered by PurCaf®, a natural, nootropic form of caffeine, PURE Stim delivers clean energy and heightened focus — without the crash associated with synthetic stimulants.

Crafted In-House for Superior Flavor:
Our flavors are hand-developed by Co-Founder and Chief Biochemist Travis Wagner, resulting in bold, refreshing taste profiles that make every sip enjoyable.

L-Citurlline DL-Malate 2:1 (6000mg)

L-Citrulline DL-Malate 2:1, a natural amino acid, boosts nitric oxide production, leading to improved blood flow, better oxygen delivery, and intense muscle pumps. In the form of L-citrulline malate, it’s shown to enhance strength, endurance, and aerobic performance, while supporting muscle growth and reducing breakdown.

Beta-Alanine (5000mg)

Beta-alanine boosts levels of carnosine, a natural muscle buffer that helps reduce acid buildup during intense training. This allows for longer, stronger workouts and improved endurance. Pure STIM includes a full clinical dose (5,000 mg) — unlike many underdosed formulas. Backed by research, beta-alanine enhances strength, delays fatigue, increases lean mass, and supports muscle health.
Note: A harmless tingling (paresthesia) may occur temporarily with use.

L-Tyrosine (2000mg)

L-Tyrosine is a precursor to dopamine and norepinephrine, key neurotransmitters that support energy, focus, and motivation. It’s especially effective under stressful conditions like intense training, enhancing mental clarity and cognitive flexibility — helping you stay sharp and adapt quickly during workouts.

L-Arginine (1000mg)

L-Arginine is an amino acid that boosts nitric oxide production, helping relax blood vessels and improve circulation. This results in enhanced muscle pumps and better nutrient delivery during workouts. Pure STIM includes a full clinical dose (2,000 mg) to maximize these effects.

Pink Himalayan Salt (400mg)

Proper salt and fluid intake supports rehydration and effective fluid distribution. Higher sodium levels in the bloodstream draw water into blood vessels, boosting blood volume and enhancing vascularity or "pump" during exercise. Consuming more sodium before exercise can also promote cell hypertrophy, increasing cell size without raising cell count.

PurCaf® (200mg)

PurCaf® is an organic, non-synthetic caffeine sourced from green coffee beans. The active compound, 1,3,7-trimethylxanthine (caffeine), is a natural CNS stimulant that boosts energy, focus, and motivation. Research shows caffeine improves exercise performance by lowering perceived effort, enhancing endurance, and supporting fat use for fuel — helping preserve muscle glycogen.

For Beginners:To assess tolerance, mix 1/2 scoop with 6 to 8 oz of water and consume 10-15 minutes before exercising, preferably on an empty stomach. If the effects feel subtle, increase to a full scoop before the next workout. 

For Experienced Pre-Workout Users:Mix 1 full scoop with 10 to 12 oz of water and consume 10-15 minutes before exercising, preferably on an empty stomach.
