LFG Burn Thermogenic Pre-Workout

You work hard. You deserve a pre-workout that works just as hard. LFG Burn Thermogenic Pre-Workout is one of Bucked Up's most powerful fat-fighting, performance-driving formulas, purpose-built for athletes who refuse to separate their fat-loss goals from their training intensity.

Set by set and sprint by sprint, LFG cranks up the heat from the inside out.* The formula fuses a proven foundation of high-performance pre-workout ingredients with a targeted thermogenic stack designed to help your body convert stored fat into fuel when combined with exercise.*

Here is what is inside and why it matters. MitoBurn (L-BAIBA, 250mg) is a studied ingredient associated with increased calorie burning during exercise.* Paradoxine (Grains of Paradise, 10mg) has been shown in research to promote fat burned during exercise.* Mucuna Pruriens Extract (98% L-DOPA, 100mg) supports the key neurotransmitter pathway involved in motivated, driven training.* Nitrosigine (1,500mg) drives increased blood flow for serious pumps and reduced fatigue.* Beta-Alanine (3,200mg) supports endurance by buffering lactic acid so you can push harder and longer.* AlphaSize (200mg) sharpens mental focus,* while Huperzine A (200mcg) may support cognitive function and memory.* AstraGin (25mg) rounds out the stack by supporting citrulline absorption.*

No proprietary blends. No fluff. No artificial colors or dyes. Just a fully transparent, hard-hitting thermogenic pre-workout formula for people who refuse to leave gains on the table. LFG. Let Fat Go.

• Nitrosigine® (Inositol-Stabilized Arginine Silicate) 1,500mg A patented complex of arginine, inositol, and silicon developed by Nutrition 21 that has been shown in multiple double-blind, placebo-controlled human trials to significantly increase nitric oxide levels, blood flow, and cognitive performance.* Clinical research at the 1,500mg dose, the exact amount used here, has demonstrated improved flow-mediated dilation, mental flexibility, and processing speed, without raising heart rate or blood pressure.*
• Beta-Alanine 3,200mg A non-essential amino acid that may increase muscle carnosine levels, which can act as a buffer against hydrogen ion buildup during intense exercise, potentially supporting endurance and stamina.* Dosed at the widely studied 3.2g amount; the harmless tingling sensation (paresthesia) is a well-documented effect at this dose.
• Caffeine Anhydrous 300mg A concentrated, fast-absorbing form of caffeine that may support alertness, mental focus, and training performance.* At 300mg per serving, roughly equivalent to three standard cups of coffee, this is a high-stim dose best suited for those with an established caffeine tolerance.
• MitoBurn® (L-BAIBA / L-β-Aminoisobutyric Acid) 250mg A patented, naturally occurring amino acid metabolite produced in skeletal muscle during exercise, studied for its potential to support fat metabolism by promoting the conversion of white adipose tissue to metabolically active brown adipose tissue when combined with exercise.* A 2022 pharmacokinetic study published in the Journal of Dietary Supplements confirmed oral bioavailability in humans; most fat-burning research used doses of 750–1,500mg/day, so the 250mg dose here is sub-clinical for those effects and is best viewed as a complementary addition.*
• AlphaSize® (Alpha-GPC 50%) 200mg A patented, highly bioavailable choline compound that may support acetylcholine production in the brain, potentially promoting mental focus and mind-muscle connection during training.* Most published research has used doses of 300–600mg; this serves as a meaningful supporting dose within the broader formula.
• Mucuna Pruriens Extract (98% L-DOPA) 100mg An extract of velvet bean, a tropical legume with a long history of use in Ayurvedic medicine, standardized to 98% L-DOPA, a direct precursor to dopamine that can cross the blood-brain barrier.* L-DOPA may help support motivation, mood, and focus, and emerging cell culture research suggests it may also play a role in fat metabolism.* Note: most clinical research on Mucuna pruriens used much higher doses of whole seed powder; the 100mg dose here at 98% standardization delivers approximately 98mg of L-DOPA, which is below typical research amounts.
• AstraGin® 25mg A patented botanical blend of Astragalus membranaceus and Panax notoginseng studied for its potential to enhance the absorption of amino acids and other key nutrients, helping maximize the effectiveness of other formula ingredients.*
• Paradoxine® (Grains of Paradise Extract / Aframomum melegueta) 10mg A patented, standardized extract of Grains of Paradise, a ginger-family spice native to West Africa, studied for its potential to activate brown adipose tissue (BAT) and increase whole-body energy expenditure when combined with exercise.* Two published human trials found that daily supplementation with Grains of Paradise extract may support thermogenesis and reductions in visceral fat.* Note: the clinical research doses were 30–40mg/day; LFG provides 10mg, which is below the studied range.
• Huperzine A (Huperzia serrata) 200mcg An alkaloid derived from Chinese club moss that may help inhibit the breakdown of acetylcholine, potentially supporting memory and cognitive performance during training.* Evidence in otherwise healthy individuals is still emerging; more robust research exists for populations with cognitive decline.
