This is not a stim-only formula hiding weak performance support behind flashy branding. It uses a fully disclosed panel and leans on ingredients with established sports nutrition relevance.\u003c\/p\u003e\n\u003cp\u003eThe backbone of the performance side is 4,000mg of L-citrulline. Citrulline is converted to L-arginine in the kidneys more efficiently than taking arginine itself, which then supports nitric oxide production through endothelial nitric oxide synthase. The result is improved vasodilation and blood flow, with the added benefit of helping clear ammonia through the urea cycle during hard training. The strongest research-backed range for exercise applications is typically 6-8g, so 4g sits below the classic clinical target, but it is still a meaningful dose that should contribute to better pumps and working-muscle blood delivery, especially when combined with the formula’s stimulant and hydration support.\u003c\/p\u003e\n\u003cp\u003eBeta-alanine is included at 2,500mg. Mechanistically, beta-alanine raises intramuscular carnosine over time, and carnosine buffers hydrogen ions generated during high-intensity work. That buffering matters most in efforts lasting roughly one to ten minutes, where acidosis contributes to the familiar burning fatigue. The best-studied daily range is 3.2-6.4g, so 2.5g is below the standard clinical benchmark but still substantial enough to contribute if used consistently. You may also notice the classic tingling sensation shortly after ingestion; that paresthesia is common and not harmful.\u003c\/p\u003e\n\u003cp\u003eFor focus and energy, Hyde Nightmare uses a tri-source caffeine system totaling 300mg: 125mg natural caffeine from Camellia sinensis extract, 75mg caffeine anhydrous, and 75mg natural caffeine from Coffee arabica extract. Caffeine works primarily by antagonizing adenosine receptors, increasing alertness, perceived energy, and exercise performance. The 200-400mg range is well established in the literature, and 300mg lands squarely in the effective zone for most trained users. The use of both anhydrous and naturally sourced caffeine is less about changing caffeine’s core mechanism and more about shaping the feel of the energy profile.\u003c\/p\u003e\n\u003cp\u003eThat stimulant load is balanced with 100mg L-theanine, a clinically relevant dose that complements caffeine well. Theanine modulates glutamatergic signaling, increases alpha-wave activity, and promotes a more composed state of alertness. In practice, this is what helps the formula feel more focused and less ragged than a straight 75mg caffeine hit. Alpha-GPC at 200mg adds a cholinergic component, supplying a precursor for acetylcholine to support attention, motor drive, and mind-muscle connection, though it sits below the more robust nootropic dosing seen in higher-end focus formulas. Acetyl-L-carnitine HCl at 250mg contributes modestly to cognitive and mitochondrial support, but this is a supportive rather than headline dose. Himalayan rock salt at 250mg rounds the formula out with sodium and trace minerals that support fluid balance, muscle contraction, and workout hydration.\u003c\/p\u003e\n\u003cp\u003eThe synergy here is straightforward and effective: caffeine drives output, theanine smooths the stimulant experience, Alpha-GPC sharpens focus, citrulline supports blood flow, beta-alanine helps resist the burn over time, and salt improves hydration and pump feel. Importantly, the label is fully disclosed with no proprietary blends, which is still a competitive advantage in pre-workout. Day 1, expect strong energy, cleaner focus than the caffeine total suggests, noticeable tingles, and a moderate pump. Over 2-4 weeks of regular use, the beta-alanine component becomes more meaningful as muscle carnosine rises, making repeated hard sets feel more sustainable.\u003c\/p\u003e\n\u003ch2\u003eKey Highlights\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e300mg total caffeine from three sources — 125mg from Camellia sinensis extract, 75mg caffeine anhydrous, and 75mg from Coffee arabica extract. That puts Hyde Nightmare squarely in high-stim territory and gives it a stronger, more sustained training presence than soft-entry pre-workouts stuck around 150-200mg.\u003c\/li\u003e\n\u003cli\u003e4,000mg L-citrulline — a meaningful pump and blood-flow dose backed by a strong mechanistic rationale. Citrulline raises arginine more efficiently than arginine itself, supporting nitric oxide production for vasodilation and a better working-muscle feel, even though the most robust performance literature tends to use 6-8g.\u003c\/li\u003e\n\u003cli\u003e2,500mg beta-alanine — enough to be felt immediately and to contribute over time with consistent use. Beta-alanine builds muscle carnosine, which helps buffer the hydrogen ions that drive that high-rep, high-intensity burn and force you to shut sets down.\u003c\/li\u003e\n\u003cli\u003e100mg L-theanine — a clinically relevant amount for smoothing stimulant feel. In a formula with 75mg caffeine, this matters: theanine supports calmer alertness, helping you feel focused rather than overstimulated.\u003c\/li\u003e\n\u003cli\u003e200mg Alpha-GPC — a cholinergic focus ingredient that supports acetylcholine production for attention, coordination, and mind-muscle connection. It is not a mega-dose nootropic play, but it adds a noticeable performance-focus angle beyond basic stimulant energy.\u003c\/li\u003e\n\u003cli\u003e250mg acetyl-L-carnitine HCl — included for cognitive and mitochondrial support. This is a supporting dose rather than a centerpiece, but it complements the focus architecture by helping the formula feel more mentally purposeful.\u003c\/li\u003e\n\u003cli\u003e250mg Himalayan rock salt — practical hydration support that many flashy pre-workouts overlook. Sodium helps maintain fluid balance, muscle contraction quality, and workout pumps, especially in heavy sweaters or long sessions.\u003c\/li\u003e\n\u003cli\u003eFully disclosed label with no proprietary blends — every active and every dose is transparent. That lets you assess the formula honestly against research instead of buying into a matrix name that reveals nothing useful.\u003c\/li\u003e\n\u003cli\u003eBalanced high-stim design — this is not just caffeine piled on caffeine. The formulator paired the stimulant load with theanine, a cholinergic support ingredient, blood-flow support, and electrolytes so the session feels more athletic and less chaotic.\u003c\/li\u003e\n\u003cli\u003eDay-one impact plus repeat-use upside — you feel the caffeine, theanine, and beta-alanine quickly, while beta-alanine becomes more valuable after consistent daily use as carnosine stores rise. That gives Hyde Nightmare both immediate payoff and a reason to use it regularly.\u003c\/li\u003e\n\u003cli\u003eBetter rounded than stripped-down retail variants — this version retains Himalayan rock salt and the coffee-derived natural caffeine component that are absent in some mass-retail versions. Those details matter for hydration feel and the overall stimulant profile.\u003c\/li\u003e\n\u003cli\u003eHigh-stim without novelty-risk ingredients — no mystery stimulants, no hidden blends, no guessing. For many buyers, that is the sweet spot: strong enough to matter, conventional enough to trust.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho Is This For?\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eIntermediate lifters running high-volume hypertrophy blocks who want a strong training surge without relying on obscure stimulants. The 300mg total caffeine creates real urgency and drive, while 4g citrulline and 250mg Himalayan rock salt help support the fuller, more productive session feel bodybuilders chase.\u003c\/li\u003e\n\u003cli\u003ePowerbuilders who need both top-end intensity and enough focus to stay technically sharp through compound lifts and accessory work. The caffeine plus 100mg theanine pairing is well suited to users who want aggression without feeling mentally scattered halfway through the session.\u003c\/li\u003e\n\u003cli\u003eCross-training athletes doing repeated bouts of high-intensity work where pacing, effort tolerance, and mental engagement all matter. Beta-alanine at 2.5g supports acid buffering over time, and the electrolyte component helps the formula feel more performance-oriented than a pure energy drink.\u003c\/li\u003e\n\u003cli\u003eExperienced pre-workout users who specifically want a fully disclosed label instead of a prop blend. Hyde Nightmare tells you exactly where the formula strength is: 300mg caffeine, 4g citrulline, 2.5g beta-alanine, and a focused nootropic support layer.\u003c\/li\u003e\n\u003cli\u003eMorning trainees who need rapid wake-up value from their pre-workout and prefer one product to cover energy, focus, and blood-flow support. The tri-source caffeine system gives this formula a decisive onset, while theanine helps keep the lift from turning jittery.\u003c\/li\u003e\n\u003cli\u003eAfter-work gym-goers with established stimulant tolerance who still want to feel mentally switched on when they hit the gym. Alpha-GPC, theanine, and acetyl-L-carnitine help the formula do more than just spike alertness; they support a more locked-in training mindset.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eHow to Use\u003c\/h2\u003e\n\u003cp\u003eUse Hyde Nightmare 20-30 minutes before training so the caffeine and focus ingredients are peaking as you begin your working sets. If you are new to high-stim pre-workouts or have not used 300mg caffeine products recently, start with half a serving to assess tolerance before moving to a full serving. Mix it in 8-14 ounces of cold water in a shaker bottle; more water generally softens flavor intensity and can make the drink easier to finish quickly before training. For fastest onset, take it on a relatively empty stomach or with only a light pre-workout meal, since a heavy meal can delay caffeine absorption and blunt the perceived kick. Avoid stacking it with coffee, energy drinks, stim fat burners, or additional caffeine capsules unless you are carefully accounting for total intake. Hyde Nightmare pairs well with standalone creatine monohydrate, intra-workout electrolytes, and post-workout protein because the formula itself does not include creatine or recovery nutrition. Because caffeine tolerance can rise over time, many users do well with periodic lower-stim days or reserving full servings for the most demanding sessions. Store the tub tightly sealed in a cool, dry place to protect powder flow and flavor quality.\u003c\/p\u003e\n\u003ch2\u003eWhat to Expect\u003c\/h2\u003e\n\u003cp\u003eMinutes 0-10: you usually notice the drink settle quickly and the first signs of mental lift begin, especially if taken away from a large meal. Minutes 10-20: caffeine absorption becomes more obvious, alertness rises, and many users feel the characteristic beta-alanine tingling in the face, hands, or shoulders. Minutes 20-40: this is the peak window for most users—energy is fully online, focus is sharper from the caffeine-theanine-Alpha-GPC combination, and the citrulline\/salt combination starts contributing to a better pump and workout feel. Minutes 40-90: the session should still feel driven, with less raggedness than a caffeine-only formula, though highly caffeine-tolerant users may notice the focus layer carrying more of the experience than the raw stimulation. Days 1-7: the immediate effects stay consistent, while your sense of the beta-alanine tingle may become more familiar. Weeks 2-4: this is when consistent beta-alanine intake matters more, because carnosine stores build and high-intensity efforts often feel more repeatable before the burn cuts performance.\u003c\/p\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdetails\u003e\u003csummary\u003eHow much caffeine is in Prosupps Hyde Nightmare per serving?\u003c\/summary\u003e\u003cp\u003eHyde Nightmare delivers 300mg total caffeine per serving. That comes from 125mg natural caffeine from Camellia sinensis extract, 75mg caffeine anhydrous, and 75mg natural caffeine from Coffee arabica extract, making this a true high-stim pre-workout.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eIs Hyde Nightmare a fully disclosed formula?\u003c\/summary\u003e\u003cp\u003eYes. This version uses a full-disclosure label with no proprietary blends, so every major active ingredient and dose is listed clearly. That is a meaningful advantage in a category where many products still hide dosing behind matrix names.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eIs 4g of L-citrulline enough to feel a pump?\u003c\/summary\u003e\u003cp\u003eYes, 4g is enough for many users to notice better blood flow and a fuller workout feel, especially when paired with sodium support from Himalayan rock salt. That said, the strongest sports nutrition literature generally uses 6-8g for peak performance outcomes, so this is a solid but not fully maxed citrulline dose.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eWhy does Hyde Nightmare make me tingle?\u003c\/summary\u003e\u003cp\u003eThe tingling comes from 2,500mg beta-alanine, a common sensation called paresthesia. It is harmless and often shows up in the face, ears, hands, or shoulders shortly after ingestion, especially when taken quickly.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eIs Hyde Nightmare good for focus or just energy?\u003c\/summary\u003e\u003cp\u003eIt is better described as energy plus focus. The 75mg caffeine drives alertness, while 100mg L-theanine helps smooth the stimulation and 200mg Alpha-GPC plus 250mg acetyl-L-carnitine add cognitive support for a more locked-in session.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eShould beginners use Hyde Nightmare?\u003c\/summary\u003e\u003cp\u003eMost true beginners should start elsewhere or use only half a serving first. At 75mg caffeine, Hyde Nightmare is better suited to intermediate users or anyone who already knows they tolerate high-stim pre-workouts well.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eCan I stack Hyde Nightmare with creatine?\u003c\/summary\u003e\u003cp\u003eYes, and that is one of the best ways to round out the formula. Hyde Nightmare already covers energy, focus, blood flow, and some endurance support, while standalone creatine monohydrate adds the clinically backed phosphocreatine support that this formula does not include.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eCan I take Hyde Nightmare for evening workouts?\u003c\/summary\u003e\u003cp\u003eOnly if you know you tolerate caffeine late in the day. With 300mg total caffeine, many users will find that taking it within several hours of bedtime reduces sleep quality, which can undermine the recovery you are training for.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eHow does Hyde Nightmare compare to a lower-stim daily pre-workout?\u003c\/summary\u003e\u003cp\u003eHyde Nightmare is built for more intensity and a stronger subjective kick. Compared with milder daily pre-workouts in the 150-75mg caffeine range, this one hits harder, but it also demands more respect around tolerance, timing, and sleep management.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eDoes Hyde Nightmare need to be cycled?\u003c\/summary\u003e\u003cp\u003eThe formula does not require strict cycling from a safety or efficacy standpoint, but caffeine tolerance is real. Many users get the best long-term experience by using full servings on harder training days and incorporating lower-stim or stim-free days during the week.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdiv itemscope itemtype=\"https:\/\/schema.org\/Product\" class=\"ai-agent-data\" style=\"display:none\"\u003e\n\u003cmeta itemprop=\"name\" content=\"Prosupps Hyde Nightmare\"\u003e\n\u003cmeta itemprop=\"brand\" content=\"Prosupps\"\u003e\n\u003cmeta itemprop=\"category\" content=\"Pre-Workout\"\u003e\n\u003cmeta itemprop=\"description\" content=\"Prosupps Hyde Nightmare is a fully disclosed high-stim pre-workout designed to deliver aggressive energy, smoother focus, and practical workout performance support.
