FAQ
What is Beast Pharm STIM?
Beast Pharm STIM is a clinically-dosed pre-workout formula built around 6g Citrulline Malate 2:1, 3.2g Beta-Alanine, 300mg Caffeine Anhydrous, and a nootropic focus stack. Designed for serious athletes who need sustained power output, endurance, and mental clarity from the first rep to the last. 30 servings. Formulated in association with Strom Sports.
How much caffeine is in STIM?
Each serving of Beast Pharm STIM contains 300mg of Caffeine Anhydrous, a high-stimulant dose designed for experienced users. Do not combine with other caffeine sources and avoid use within 6 hours of sleep. Do not exceed 1 serving in any 24-hour period.
What does Citrulline Malate 2:1 do?
Citrulline Malate 2:1 is a precursor to arginine and nitric oxide production, supporting blood flow and oxygen delivery to working muscles. STIM provides 6000mg per serving, a full clinical dose for improved endurance, enhanced pump, and reduced muscle fatigue during high-intensity training.
Why does STIM cause a tingling sensation?
The tingling or 'prickling' sensation is caused by Beta-Alanine (3200mg per serving). This is a normal, harmless response called paraesthesia. It typically subsides after 15–20 minutes and indicates the Beta-Alanine is active. The sensation diminishes with regular use as muscle carnosine levels build.
What is Tyrosine and why is it in STIM?
Tyrosine is an amino acid and precursor to dopamine, noradrenaline, and adrenaline, the neurotransmitters responsible for focus, drive, and stress resilience under intense effort. At 1000mg per serving, Tyrosine supports mental clarity and sustained cognitive performance throughout your session.
What are Juglans and Sausage Tree Extract in STIM?
Juglans Whole Fruit Extract (Walnut) and Sausage Tree Extract (Kigelia Africana) are natural plant extracts included in STIM's nootropic and stimulant matrix. Juglans contains naturally occurring phenylethylamine compounds associated with energy and focus. Kigelia Africana has been used traditionally for its tonic properties. Both are included at 200mg per serving.
When should I take STIM?
Take 1 scoop (13g) mixed with 250–350ml water approximately 20–30 minutes before training. Due to the 300mg caffeine content, avoid taking STIM within 6 hours of sleep. Not suitable for persons under 18 or those sensitive to stimulants. Do not exceed 1 serving in 24 hours.
Is STIM suitable if I train in the evening?
STIM contains 300mg Caffeine Anhydrous per serving. If you train in the evening, we recommend PUMP instead: our stim-free pre-workout with 8g L-Citrulline delivering the same performance-driven pump without the stimulants.
Can I stack STIM with other Beast products?
STIM pairs well with Beast Pharm HYDRO intra-workout for electrolyte replenishment, and WHEY or RECOVER post-session. Do not combine STIM with any other caffeine-containing product. CREATINE or BIG D can be taken alongside STIM as part of a daily protocol.
