It contains ~\u003cstrong\u003e350 mg of caffeine from natural sources\u003c\/strong\u003e (anhydrous caffeine + green tea + green coffee) and \u003cstrong\u003e4000 mg of beta-alanine\u003c\/strong\u003e, with 19 additional active ingredients. 300g, 27 servings of 11g. Flavors: Blue Razz and Sweet Lemonade. Mix 1 scoop (11g) in 250 ml of water, 15 to 30 minutes before training.

The \u003cstrong\u003eenergy and cognitive axis\u003c\/strong\u003e includes the three caffeine sources (~350 mg total), L-Theanine (which smooths caffeine's effect without reducing energy), L-Tyrosine and Choline Bitartrate (for catecholaminergic and cholinergic neurotransmission), Bacopa monnieri and Rhodiola rosea (nootropic adaptogens). The \u003cstrong\u003ephysical performance axis\u003c\/strong\u003e includes 4000 mg beta-alanine (H⁺ buffering), creatine monohydrate (PCr resynthesis), anhydrous betaine (endogenous carnitine and creatine synthesis), L-Taurine (muscle function and cell hydration). The \u003cstrong\u003ethermogenic axis\u003c\/strong\u003e includes bitter orange extract (p-synephrine), green coffee (chlorogenic acid), green tea (EGCG), Coleus forskohlii\/Forslean (forskolin via cAMP), cayenne pepper (capsaicin via TRPV1) and Citrus aurantium bioflavonoids. The \u003cstrong\u003epump and vasodilation axis\u003c\/strong\u003e includes willow bark (salicin, a precursor to salicylic acid with vasodilatory and anti-inflammatory effects) and citrus bioflavonoids.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003e~350 mg of caffeine from three sources with distinct kinetics: rapid onset + prolonged duration:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eAs described in multiple previous pre-workouts in this session, the combination of \u003cstrong\u003eanhydrous caffeine\u003c\/strong\u003e (rapid onset, 15-30 min), \u003cstrong\u003egreen tea extract\u003c\/strong\u003e (Camellia sinensis with 7% caffeine, intermediate onset) and \u003cstrong\u003egreen coffee bean\u003c\/strong\u003e (Coffea robusta 12:1 with caffeine complexed with chlorogenic acid, slower onset) creates a flatter and more prolonged energy curve than isolated anhydrous caffeine. The total dose of ~350 mg of caffeine is a high dose, suitable for athletes with established caffeine tolerance, but which can cause adverse effects (tachycardia, anxiety, insomnia) in sensitive or unaccustomed individuals.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eL-Theanine: caffeine's cognitive modulator:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eL-Theanine\u003c\/strong\u003e (gamma-ethylaminoacid-L-glutamic acid), an amino acid almost exclusive to green tea (Camellia sinensis), is the natural nootropic that uniquely complements and modulates caffeine. The caffeine + L-Theanine combination is the nootropic combination with the most clinical trials and most consistently documented for improving attention, processing speed, and working memory compared to each compound alone. The mechanism is synergistic: L-Theanine increases alpha brain wave activity (associated with a state of relaxed alertness, creativity, and focus without anxiety) and partially antagonizes the anxiogenic and jitteriness effects of caffeine (by modulating NMDA and GABA-A receptors), resulting in a profile of \"focused energy\" without the nervousness or crash associated with isolated caffeine.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eBeta-alanine 4000 mg: the clinical standard dose for maximum muscle carnosine synthesis:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eWith \u003cstrong\u003e4000 mg of beta-alanine per serving\u003c\/strong\u003e, Power M.F uses the dose confirmed in the most robust studies on beta-alanine (doses between 3.2 and 6.4 g\/day are the most studied). As described in the standalone \u003cstrong\u003eBeta Alanine\u003c\/strong\u003e section of Marvelous Nutrition, beta-alanine is the limiting precursor for muscle carnosine synthesis which buffers H⁺ produced during high-intensity exercise. 4000 mg per serving fully covers the 3.2 to 4 g\/day documented as effective for increasing muscle carnosine content in 4 to 8 weeks of regular use.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eCreatine monohydrate: the anabolic synergy with beta-alanine in the same pre-workout:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe inclusion of \u003cstrong\u003ecreatine monohydrate\u003c\/strong\u003e in Power M.F creates the most studied performance stack in sports nutrition history — creatine + beta-alanine — in a single pre-workout dose. Creatine supports the phosphagen system (\u0026lt;10 seconds of maximum effort) and beta-alanine\/carnosine supports H⁺ buffering (30 to 240 seconds). Together, they cover the two main energy systems of high-intensity exercise. The meta-analysis by Hobson et al. (2012) documented that the creatine + beta-alanine combination produced greater gains in muscle mass and better performance outcomes than each supplement alone.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eAnhydrous betaine (trimethylglycine): methyl group donor and endogenous creatine precursor:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eAnhydrous betaine\u003c\/strong\u003e (trimethylglycine, TMG) has multiple mechanisms of action relevant to performance. It is a methyl group donor that supports endogenous creatine synthesis (via methylation of guanidinoacetate to creatine by GAMT, using SAM as a methyl donor, and betaine recycles homocysteine to methionine via BHMT, replenishing SAM). It also has osmoprotective properties (it accumulates intracellularly in response to osmotic stress, protecting cells from dehydration) and can increase muscle power and endurance independently of creatine. The study by Cholewa et al. (2013) documented that 2.5 g\/day of betaine for 6 weeks increased muscle power and body composition (greater muscle mass, less fat) compared to placebo.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eBacopa monnieri 10% and Rhodiola rosea 20:1: the two nootropic adaptogens in the cognitive stack:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eBacopa monnieri\u003c\/strong\u003e (Brahmi) is an Ayurvedic adaptogen with documented effects on memory, cognitive processing, and anxiety reduction. It contains bacosides A and B as active compounds that inhibit acetylcholinesterase (increasing synaptic acetylcholine availability) and have antioxidant effects on neurons. \u003cstrong\u003eRhodiola rosea\u003c\/strong\u003e (20:1 extract, rich in rosavins and salidrosides) is the most studied adaptogen for reducing mental and physical fatigue in contexts of acute stress, with multiple clinical trials documenting reduced tiredness, improved mood, and work capacity during periods of stress. The combination of these two plants with caffeine and L-Theanine creates a nootropic stack that supports cognition during long or high-intensity workouts where mental fatigue is a limiting factor.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eForslean® (Coleus forskohlii 35:1): direct activation of adenylate cyclase and cAMP:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eAs described in the Thermo Full and Thermo 10 sections of Life Pro, \u003cstrong\u003eforskolin\u003c\/strong\u003e from Coleus forskohlii directly activates adenylate cyclase, increasing intracellular cAMP independently of adrenergic receptors — the same second messenger activated by caffeine (via phosphodiesterase inhibition) and p-synephrine (via β3 receptors). The use of the \u003cstrong\u003eForslean®\u003c\/strong\u003e brand (Sabinsa Corporation) indicates a standardized extract of certified quality, at a 35:1 concentration (much more concentrated than the 4:1 Coleus forskohlii in Life Pro Thermo Full, meaning a higher forskolin content per gram of extract).\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eBitter orange (p-synephrine 15:1) + Citrus aurantium bioflavonoids: the natural thermogenic pair:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe \u003cstrong\u003e15:1\u003c\/strong\u003e bitter orange extract has a significantly higher concentration of p-synephrine than the 6% synephrine extract in Evidenced Burner (Life Pro), given that the concentration ratio is 15:1. Citrus aurantium bioflavonoids (hesperidin, naringenin, nobiletin) enhance the thermogenic effect of p-synephrine via additional COMT inhibition (prolonging noradrenaline's action) and have vasodilatory properties that contribute to muscle pump.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eWillow bark (Salix alba 8:1): the natural NSAID that enhances vasodilation:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eWhite willow bark\u003c\/strong\u003e contains \u003cstrong\u003esalicin\u003c\/strong\u003e (phenolic glycoside) which is hydrolyzed in the intestine into saligenin + glucose, then oxidized in the liver to salicylic acid (the active metabolite). Salicylic acid inhibits COX-1 and COX-2 (with less potency than acetylsalicylic acid), having anti-inflammatory and potentially vasodilatory effects (via reduction of thromboxane A2 production, which is a vasoconstrictor). In the context of a pre-workout, willow bark contributes to the reduction of acute inflammation during training and to improved muscle blood flow.\u003c\/p\u003e\n\u003ch3 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eUsage\u003c\/h3\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eRecommended dose:\u003c\/strong\u003e Mix 1 scoop (11g) in 250 ml of cold water, 15 to 30 minutes before training. Start with half a dose (5.5g) to assess tolerance to caffeine (~175 mg) and beta-alanine (paresthesia) before progressing to the full dose. Avoid consumption after 4 PM to avoid disrupting sleep.
