insights Analysis
Pre JYM High-Performance Pre-Workout stands out due to its fully disclosed ingredient label, which is a significant advantage in a market often plagued by proprietary blends. It provides a robust combination of performance enhancers like Citrulline Malate (6g), Creatine HCl (2g), Beta-Alanine (2g), and BCAAs (6g at 2:1:1 ratio), alongside a potent energy and focus blend including 300mg Caffeine, 1.5g L-Tyrosine, 150mg Alpha-GPC, and 50mcg Huperzine A. This comprehensive profile is designed to support multiple workout goals, from strength and endurance to mental acuity. While the Beta-Alanine dose is slightly below the commonly studied clinical range for full benefits (typically 3.2g+), and Alpha-GPC is a bit lower than some optimal nootropic doses, the overall synergy of ingredients is impressive. Reviews generally praise its effectiveness in delivering sustained energy, noticeable pumps, and sharp focus without a harsh crash. The price per serving is on the higher side, but it reflects the quality and quantity of active ingredients per dose.
- Comprehensive formula with transparent ingredient dosages, avoiding proprietary blends.
- Contains clinically studied ingredients for performance (Citrulline, Creatine, Beta-Alanine, BCAAs) and cognitive benefits (Caffeine, Tyrosine, Alpha-GPC, Huperzine A).
- High caffeine content (300mg) provides a strong and reliable energy boost.
- Includes BCAAs in a good ratio for muscle support and recovery during workouts.
- Supports enhanced blood flow and muscle pumps with Citrulline Malate and Beet Root Extract.
- High price per serving ($1.79) compared to many other pre-workout supplements on the market.
- The Beta-Alanine dose (2g) is slightly below the most commonly studied clinical range (3.2-6.4g daily) for maximizing endurance benefits and paresthesia reduction.
- Alpha-GPC dose (150mg) is on the lower side for maximum cognitive enhancement, with many studies using 300-600mg.
- Very low potassium (77mg) and sodium (10mg) content, which are insufficient for significant electrolyte replenishment during intense physical activity.
- High caffeine content (300mg) may cause jitters, anxiety, increased heart rate, or difficulty sleeping for individuals sensitive to stimulants.
- Not suitable for individuals with pre-existing cardiovascular conditions or those advised to limit caffeine intake.
- Contains Beta-Alanine which can cause a harmless tingling sensation (paresthesia), although at 2g it might be less pronounced than higher doses.

bolt Effectiveness for goals
Betaine acts as an osmolyte, helping to maintain cellular hydration and fluid balance within muscles. Research suggests it can support improvements in power output, muscular endurance, and potentially body composition.
Taurine supports cellular hydration, electrolyte balance, and overall muscle function. It may help reduce exercise-induced muscle damage and improve endurance, contributing to sustained performance during workouts.
Caffeine provides immediate stimulation and alertness. L-tyrosine supports the synthesis of neurotransmitters crucial for cognitive function under stress. Alpha-GPC and Huperzine A further enhance brain function by supporting acetylcholine levels, a key neurotransmitter for focus and memory.
Both Citrulline Malate and beet root extract are precursors to nitric oxide, a molecule that helps relax blood vessels. This combined action may enhance blood flow, nutrient delivery to muscles, and support exercise performance and pumps.
Beta-alanine helps increase muscle carnosine levels, which buffer lactic acid buildup during high-intensity exercise, potentially delaying fatigue. The tingling sensation, known as paresthesia, is a common and harmless side effect that typically subsides with continued use.
schedule Dosage, timing & forms
It is generally recommended to avoid caffeine at least 6-8 hours before bedtime to prevent sleep disruption. Individual sensitivity to caffeine can vary, so adjust based on personal experience.
Yes, the tingling sensation, known as paresthesia, is a common and harmless side effect of beta-alanine. It is typically felt in the skin and subsides after a short period.
While 2 grams of Creatine HCl contributes to daily intake, the commonly recommended daily maintenance dose for creatine monohydrate to achieve muscle saturation is typically 3-5 grams. Creatine HCl may be effective at lower doses due to enhanced solubility compared to monohydrate.
For most pre-workout ingredients, consuming the supplement approximately 20-30 minutes before your workout is often recommended. This allows sufficient time for ingredients like caffeine and citrulline malate to be absorbed and become effective.
BioPerine, a black pepper extract, is known to enhance the bioavailability of various nutrients by temporarily increasing their absorption. It works by inhibiting certain enzymes and enhancing the thermogenic response. This can lead to more effective delivery of other compounds.
health_and_safety Safety & interactions
A 300mg dose of caffeine is substantial and can lead to effects like increased heart rate, anxiety, or difficulty sleeping, especially for individuals sensitive to stimulants. It is advisable to avoid consuming other caffeinated beverages or products when using such a supplement. Individuals with pre-existing heart conditions or those taking certain medications should consult a healthcare professional.
Yes, black pepper fruit extract, containing piperine, is known to enhance the bioavailability of certain compounds by influencing metabolic enzymes. This effect may increase the absorption and potency of some medications or other supplement ingredients. It is recommended to consult a healthcare professional if you are taking any prescription medications.
Huperzine A can increase acetylcholine levels in the brain, which may interact with medications that also affect this neurotransmitter, such as certain Alzheimer's drugs. Potential side effects can include nausea, diarrhea, sweating, or blurred vision. Individuals with epilepsy or heart conditions should exercise caution and consult a professional.
The tingling sensation, known as paresthesia, is a common and harmless side effect of Beta-Alanine, especially at doses like 2 grams. It typically occurs on the skin of the face, neck, or hands shortly after consumption and subsides as the body adapts. This effect is temporary and not considered dangerous.
Combining several stimulant and nootropic ingredients like caffeine, L-Tyrosine, AlphaSize, and Huperzine A may heighten their individual effects. This can potentially lead to increased alertness but also a higher risk of side effects such as jitters, anxiety, or sleep disturbances. Monitoring your tolerance and avoiding other stimulants is advisable.
