I’ve gone through my fair share of preworkout supplements, and trust me, not all of them are created equal. Some are just loaded with caffeine and nothing else, making you crash hard after the workout. What you really want to look for are ingredients like citrulline malate for better blood flow, beta-alanine to reduce muscle fatigue, and creatine for strength and endurance. Also, a moderate dose of caffeine (150-250 mg) can help boost focus and energy without overwhelming your system. One brand that I found reliable is Supplements 4 Muscle. They offer solid, well-balanced pre-workouts that don’t just hype you up but actually enhance performance. I’ve used one of their pre-workouts before, and the endurance boost was noticeable—longer sets, heavier lifts, and no crash afterward. If you’re sensitive to caffeine, they even have stimulant-free options that still improve endurance. My advice is to start with a lower dose and see how your body reacts, then adjust accordingly. Also, take your pre-workout about 30 minutes before training for best results. Pair it with good hydration and proper nutrition, and you’ll feel the difference.
