What Does iPrep Advanced Pre-Workout Do?
iPREP is a strong, stimulant-heavy pre-workout with solid creatine and beta-alanine, but the caffeine and synephrine load make it aggressive for sensitive users. The pump-support ingredients are present, though some are underdosed compared with common research ranges.

Overview
•This is a high-stimulant formula with 320 mg caffeine plus 40 mg synephrine, so it may cause jitteriness, palpitations, or a rapid heart rate in sensitive users.
•Not for people under 18, pregnant or nursing, or anyone with medical conditions or taking medications without medical advice; the label also warns against combining with other stimulants.
•Beta-alanine commonly causes temporary tingling/flushing, which may be more noticeable at a 2 g dose.
•Synephrine and caffeine can raise cardiovascular strain, so caution is warranted with high blood pressure, heart rhythm issues, or anxiety.
•No major allergen ingredients are listed, but it is processed in a facility that also processes milk, sesame, and soybean.
•Because the serving is stimulant-heavy, starting with half a scoop is safer than taking a full scoop immediately, especially for first-time users.

Dosage & Bioavailability
How the active doses and forms in iPrep Advanced Pre-Workout compare to the research.
•Creatine monohydrate is fully dosed at 5 g, but L-citrulline is only 500 mg and arginine HCl 500 mg, both well below typical pump-oriented ranges.
•Beta-alanine at 2 g is helpful but still below the common 3.2 g/day performance dose.
•Caffeine 320 mg plus synephrine HCl 40 mg makes this a high-stimulus formula; the label suggests half-scoop starts for tolerance, but the active stack still remains potent.
