MitoBurnโข (L-BAIBA) Explained: Fat Loss, Energy & Metabolic Support
In the evolving world of metabolic and performance supplements, MitoBurnโข is fast becoming a standout ingredient. Short for L-ฮฒ-Aminoisobutyric Acid (L-BAIBA), MitoBurn is a patented form of this naturally occurring myokine-like compound, and itโs being recognised for its potential to support fat metabolism, energy output, and body composition. What Is MitoBurnโข? MitoBurnโข is a trademarked version of L-BAIBA, a molecule produced in skeletal muscle during intense exercise, especially under conditions that stimulate PGC-1ฮฑ (a regulator of mitochondrial biogenesis). BAIBA is known to act as a signal to the body, promoting fat oxidation and the browning of white adipose tissue. In simpler terms, encouraging the body to convert energy storing white fat into energy burning brown fat. Itโs often referred to as an "exercise mimetic" compound because it mimics some of the beneficial effects of high-intensity exercise at the cellular level. What Are the Benefits of MitoBurnโข? Emerging research and real-world application of MitoBurnโข suggest it may support: Increased fatty acid oxidation Improved mitochondrial function and energy metabolism Support for body recomposition (fat loss with muscle retention) Enhanced thermogenesis Exercise mimetic effects, even at rest MitoBurnโข may also indirectly support glucose regulation and insulin sensitivity by improving how the body metabolises energy, making it a promising ingredient in fat burners, recomposition formulas, and performance stacks. How Does MitoBurnโข Work? L-BAIBA is released in response to muscle contraction and acts as a signalling molecule. It helps up regulate pathways involved in lipid oxidation, supports mitochondrial function, and encourages the conversion of white adipose tissue to brown adipose tissue. This shift is associated with increased energy expenditure and metabolic flexibility. MitoBurnโข also appears to reduce markers of inflammation, making it a potential aid in recovery and healthy aging protocols. Who Is MitoBurnโข For? MitoBurn is ideal for: Individuals working on fat loss or body recomposition Athletes aiming to enhance metabolic efficiency and endurance People with sedentary jobs seeking metabolic support Individuals managing blood sugar or insulin sensitivity Biohackers and longevity enthusiasts Because it mimics part of the body's natural exercise response, it fits seamlessly into both active and more lifestyle-focused routines. How to Take MitoBurnโข Effective dosages of MitoBurnโข (L-BAIBA) typically range from 250 mg to 500 mg per day. Itโs commonly found in thermogenic fat burners, pre-workouts, and metabolic support stacks. For best results, take it consistently, often before training or with your morning supplement routine. It can be stacked effectively with ingredients like Grains of Paradise, L-Carnitine, GBB, and caffeine to enhance thermogenesis and fat oxidation.

Supps Simplified: What NMN Can Do for Your Energy, Recovery & Longevity
In the conversation around aging, performance, and longevity, NMN,ย short for Nicotinamide Mononucleotide, has quickly gone from obscure compound to essential staple in many advanced health stacks. But behind the hype is a very real molecule with significant backing in cell biology and metabolism research. What Is NMN? NMN is a naturally occurring molecule found in small amounts in foods like edamame, broccoli, and avocado. It serves as a direct precursor to NAD+ (Nicotinamide Adenine Dinucleotide)ย one of the most critical coenzymes in the body. NAD+ is involved in over 500 biochemical reactions, including energy production in the mitochondria, regulation of circadian rhythm, DNA repair, gene expression, and cellular stress response. However, NAD+ levels naturally decline with age, which has been linked to age related metabolic disorders, impaired mitochondrial function, and slower cellular recovery. Studies have shown that supplementing with NMN can increase NAD+ levels in blood, muscle, and brain tissue, helping to restore some of the functional efficiency lost over time. This makes NMN a potential game changer not only in the longevity space but also in performance, cognition, and general wellbeing. What Are the Benefits? While NMN is still under extensive scientific investigation, current human and animal studies suggest it may support: Increased cellular energy metabolism and mitochondrial performance Improved insulin sensitivity and glucose metabolism Enhanced cardiovascular function and blood flow Better cognitive function and memory recall Improved endurance and reduced fatigue Protection against age related decline in organ function Unlike stimulants or quick-fix energy boosters, NMN works gradually and systemically improving how cells work from the inside out. Emerging Research: More Than Just Longevity Recent research suggests NMN may also play a role in protecting against neurodegeneration and inflammation. Animal studies have shown improvements in markers of cognitive health, memory, and neuroplasticity when NMN was used to restore NAD+ levels in the brain. Some studies have also observed improvements in vascular elasticity and mitochondrial density in skeletal muscle, which could have implications for both healthy aging and sports performance. Itโs worth noting that NMN is being closely studied in clinical settings, including trials focusing on cardiovascular health, age related muscle loss, and metabolic syndrome. Who Is NMN For? NMN is ideal for: Individuals aged 30+ seeking proactive cellular support Athletes looking to support recovery, performance, and mitochondrial output Professionals or high performers aiming to maintain energy and focus Anyone looking to support longevity and reduce signs of biological aging Whether you're optimising for quality of life, healthy aging, or long-term resilience, NMN is a tool that helps support your body at the cellular level. How to Take NMN Research and user protocols suggest effective dosages range from 250mg to 1000mg per day, depending on your age, health goals, and response. Beginners often start at 250โ500mg, while more advanced users aiming to optimise longevity and cellular function may go up to 1000mg daily.

Faction Labs Disorder Pump Review: Is This Australiaโs Best Non-Stim Pre-Workout?
Faction Labs has officially retired its previous stim-free product, Bulge, and replaced it with a completely reimagined non-stimulant formula, Disorder Pump. Designed to deliver intense pumps, mental focus, and improved performance all without caffeine. This product is clearly built to stack with the original Disorder, but does it live up to the expectations? Letโs break it down. ย Formula Breakdown: Does It Deliver on All Fronts? This is where things get interesting. With a name like Disorder Pump and a legacy to live up to, the formula promises more than just a pump... it's designed to hit all the right areas without relying on stimulants. So, how does it actually perform across the key categories?We scored Disorder Pump across five key performance categories: Pump, Endurance, Hydration, Power, and Focus. Absorption is considered an added benefit but not scored in the final rating. Pump โ 4/5 Disorder Pump includes 3000mg of L-Citrulline, 1500mg of GlycerSizeโข (Glycerol), 1500mg of Betaine Nitrate, and 750mg of Agmatine Sulfate, a potent pump stack that supports nitric oxide production, blood flow, and muscle volume. Whatโs Missing: A higher L-Citrulline dose (4000mg is the clinical standard). Focus โ 4.5/5 With 1000mg of L-Tyrosine, 600mg of Alpha GPC (50%), 200mg of L-Phenylalanine, and 250mcg of Huperzine A, Disorder Pump delivers an impressive nootropic effect, especially for a stim-free product. It keeps your head clear and your focus dialled in without jittery side effects. Whatโs Missing: A bump to 800mg of Alpha GPC and the addition of L-Theanine could have made the focus blend more well rounded. Endurance โ 3.5/5 Disorder Pump includes 1600mg of Beta-Alanine and 1000mg of Taurine, enough to support muscular endurance and reduce fatigue in short to moderate training sessions. Whatโs Missing: The Beta-Alanine dose is half of the 3.2g clinical standard. Also, the absence of adaptogens like PeakO2ยฎ or Rhodiola limits the endurance potential. Hydration โ 3.5/5 Taurine and 500mg of Himalayan Pink Salt offer a solid base for hydration and electrolyte replenishment. This is especially useful for pump support and prolonged workouts. Whatโs Missing: Additional electrolytes like Magnesium and Calcium would improve hydration support further. Power โ 2.5/5 Thereโs no Creatine, Betaine Anhydrous, or ElevATP in the mix, which means Disorder Pump lacks the ingredients typically used for supporting raw strength and power output. Betaine Nitrate does provide some performance crossover, but not enough for those focused on strength progression. Whatโs Missing: Creatine or strength enhancing ingredients to round out the performance profile. Absorption (Bonus Category) โ 4/5 The inclusion of Piperine (Black Pepper Extract) and Vitamin C helps improve nutrient uptake and overall bioavailability. Whatโs Missing: AstraGinยฎ or a higher dose of Piperine could further enhance the absorption effectiveness. Final Ratings Summary Pump: 4/5 Endurance: 3.5/5 Hydration: 3.5/5 Power: 2.5/5 Focus: 4.5/5 Absorption (Bonus): 4/5 Overall Score (out of 25): 18/25 Disorder Pump brings solid performance across pumps and focus, making it an ideal stim-free option for anyone wanting to stay sharp and pumped without the caffeine crash. It may not tick every box, but for a non-stim pre, it lands in the sweet spot between simplicity, effectiveness, and flavour. Flavour Options Disorder has built a reputation for delivering some of the best tasting pre-workouts in Australia, and Disorder Pump lives up to that legacy. Each flavour is enjoyable, and blends easily with water or stacked formulas. Black Fire (Grape) โ Classic candy grape Purple Reign (Watermelon) โ Fruity and refreshing Red Russian (Raspberry) โ Sweet raspberry candy Plain Jane โ Unflavoured for stacking flexibility The flavours are bold & sweet without being overpowering, and mixability is decent even with high glycerol content. Price & Value RRP: $59.95 AUD Servings: 25 per tub Cost per serve: ~$2.40 When you consider the level of performance, the added focus support, and the flavour experience Disorder Pump brings to the table, especially in a stim-free formula,ย the price feels more than fair. It's a good option that offers real value for its cost per serve. Supplement Comparison ย When it comes to stim-free pre-workouts, thereโs no shortage of competition, but not all of them deliver where it counts. Disorder Pump lands in the middle of all of them and aims to offer versatility and flavour. While it doesnโt quite match the full spectrum formula ofย Transparent Labs Pump Juice, it stacks up well against: Rule 1 Pump Ghost Pump Nexus Amp3d Disorder Pumpโs standout feature is its flavour profile and nootropic support, which makes it an excellent pick for stacking with your favourite stim-based pre. Itโs not the most loaded formula out there, but it makes up for that with smart dosing and usability across training styles. Who Is This For? Best for: Evening athletes training at night Anyone cycling off caffeine Anyone stacking with stim-based pre-workouts (like original Disorder) Not ideal for: Strength focused athletes looking for Creatine or Betaine based power. People wanting full clinical doses in every category Final Thoughts Disorder Pump replaces Faction Labs Bulge with a more complete, better tasting, and more stackable stim-free formula. While it misses a few full clinical doses, it covers its core categories well and brings added value with its nootropic edge. Pros: โ Solid pump + focus comboโ Stimulant-free and stackableโ Great flavours, including unflavouredโ Good value per serve Cons: โ Some underdosed ingredientsโ Lacks power-specific support Verdict: Whether you're training at night, avoiding caffeine, or stacking with a stim-based pre, Disorder Pump is a good non-stim pre-workout with wide appeal.

The Tight Grip of Aussie Laws On Pre-Workouts
Supplement formulas have always pushed the limits when it comes to intense stimulant blends. When a pre-workout manufacturer, especially in Australia, wants to create a new pre-workout with stimulants, they have to be very careful with what they choose. Why? Australian laws. Australia has a keen eye on the supplement industry when it comes to effectiveness vs regulations. If you miss that one pre-workout that used to make you, and wondered why it left the shelves, then read on. The Therapeutic Goods Administration (TGA) and Supplement Regulation The supplement industry in the land down under is under the careful eye of the Therapeutic Goods Administration (TGA), within the health department of the government. In the U.S. many supplements are treated as food products, and are left to the manufacturers to deem them safe for consumption. However, in Australia, the TGA is in charge of regulating any ingredients in your favourite pre-workout that significantly affects the body, like a strong stimulant, and treating it as a medicine. This means that pre-workouts with high doses of stimulants must be under the same banner and pharmaceutical drugs. If a supplement raises your heart rate, blood pressure or increases your focus that little too much, then itโll be classed as a medicine. This means itโll have to go through the long processes for official approval, or itโll be banned from being sold entirely. The Crackdown On Stimulants The Australian government has a history of banning ingredients, mostly stimulants, in pre-workouts. A handful of the well known ones include: DMAA (1,3-Dimethylamylamine) โ Once a big part of the hardcore pre-workout scene. This strong stimulant was banned after the risks of heart problems, strokes and even fatalities. DMHA (2-Aminoisoheptane) โ Once DMAA was off the market, DMHA came onto the scene. However, that was quickly banned as well because of the same health risks Beta-Phenylethylamine (PEA) โ Another strong stimulant known for increasing both energy and focus. PEA is banned because of its side effects on the heart. Spot the pattern? The majority of these stimulants are banned due to their effects on your heart and cardiovascular system.ย Caffeine Limits If you were hoping that caffeine is free from the TGAโs grasp, youโd be mistaken. In the U.S. supplements can have formulas of 300-400mg of caffeine per scoop on the higher end. Australia limits caffeine to 80mg per 250ml, or roughly an average cup of instant coffee, in energy drinks. This is why youโll see energy drinks with no more than 160mg of caffeine per 250ml. For powdered pre-workouts, the serving of caffeine canโt exceed 5% of the serving size. Meaning that for every 10g of powder, you canโt go over 500mg of caffeine. These regulations mean you still get a caffeine boost of energy, but a safe boost. How This Affects Supplement Consumers in Australia If youโre in the market for a new high-stim pre-workout, your choices will be limited. Many of the world's hardest hitting formulas wonโt make it to Aussie shelves. The ones that do more than likely have to have a version thatโs compliant and a bit lighter on the stimulants. Itโs frustrating to have your favourite pre-workout get pulled from shelves, but thereโs a valid argument as to why they get pulled. The regulations are in place to protect consumers from dangerous, and potentially deadly side effects. Unregulated pre-workouts, with some seriously strong stimulants, have been linked to serious health risks, including heart attacks and strokes. Manufacturer Workarounds Even with Australiaโs strict regulations, pre-workout manufacturers are finding ways to still keep the strong effects and stay in line with the TGAโs demands. An example would be higher stimulant pre-workouts directing you to mix them with upwards of 500ml of water, to keep them within the 80mg per 250ml limit. Another way that they work around the regulations is by adding naturally occurring stimulants such as english walnut extract (Juglans Regia) and bitter orange extract (synephrine). This way you can still have your strong, hardcore pre-workout in Australia. Plus the added active ingredients means that the caffeine wonโt go over 5% of the serving size. The Future of Pre-Workout Regulation in Australia The Australian pre-workout market is still thriving, giving people the ability to push their limits when theyโre training. The TGA may seem like theyโre trying to take all the fun out of pre-workouts. In reality, theyโre making them safer and reducing risks of adverse effects. Sure, they wonโt have as strong an effect as current regulated ingredients, but if the payoff means not dying, Iโd say itโs worth it.
