Building a supplement stack doesn't have to be complicated. Whether you're brand new to training or you've been at it for years, there are four core categories that every stack should cover: protein, a fat burner or thermogenic, amino acids, and hydration. Get these four right, and you've got a solid foundation to support your goals — whether that's building lean muscle, losing body fat, or simply performing better every day.
Here's a breakdown of the best products to fill each of those four slots right now.
1. Protein
Protein is non-negotiable. It's the building block your muscles need to repair and grow after training, and it helps keep you feeling fuller for longer — which is key when you're in a calorie deficit. Aim for at least one serve per day, post-workout being the most important window.
Lean Whey by Genetix Nutrition
A premium WPI and WPC blend using ultra-refined New Zealand whey. Lean Whey delivers a steady release of protein to keep your muscles fuelled, with a smooth texture and great taste. Naturally rich in BCAAs and glutamine, it's ideal for daily use by active men and women looking to support lean muscle and recovery.
OxyWhey by EHP Labs
OxyWhey brings a multi-phase protein system with a 70:20:10 ratio of WPI, WPC, and micellar casein for both rapid and sustained amino acid delivery. With 24g of protein per serve, over 5g of BCAAs, added digestive enzymes, and a low-fat, low-carb, gluten-free profile — it's a clean and effective everyday option for those focused on performance and lean muscle maintenance.
2. Fat Burner / Thermogenic
A quality thermogenic can support your fat loss goals by helping you stay energised, focused, and consistent — especially during calorie-controlled phases. The key is finding one that fits your tolerance for stimulants and works with your daily routine.
Ripp3d by Anabolix Nutrition
Ripp3d is built for those who want to push harder in the gym while supporting their body composition goals. Free from fillers and proprietary blends, its transparently dosed ingredient profile is designed to enhance calorie processing, boost energy, improve focus and mood, and complement your diet and exercise routine. A standout option for those who want a potent, no-nonsense thermogenic.
Hydroxy Lean by Genetix Nutrition
If you prefer a lower-stimulant approach, Hydroxy Lean is a smart pick. Formulated with patented, scientifically researched ingredients and natural caffeine sources, it delivers clean, long-lasting energy without the crash — making it suitable for daily use. Ideal for anyone who wants consistent energy and mental clarity without overstimulation.
Meltz by PharmaLabs
Meltz is designed for those who want a smarter, more controlled approach to fat loss — without the intensity of traditional fat burners. With moderate stimulation and a smooth, consistent feel, Meltz supports daily use during calorie-restricted phases. It pairs easily with proteins, pre-workouts, and wellness supplements, making it simple to slot into your existing stack.
3. Amino Acids / Recovery
Amino acids are the building blocks of protein and play a crucial role in muscle repair, reducing soreness, and preventing muscle breakdown — especially important during dieting phases or high-volume training blocks. Sipping on EAAs or BCAAs intra-workout or post-workout can make a noticeable difference to how quickly you bounce back.
Minos by PharmaLabs
Minos delivers a complete blend of EAAs and BCAAs in one formula, enhanced with AstraGin® for improved nutrient absorption and gut health, plus Tart Cherry Extract to support muscle recovery and reduce inflammation. Research shows that consuming EAAs pre-exercise can stimulate an anabolic response while minimising muscle breakdown — making Minos an excellent addition to any training stack.
Revive by Genetix Nutrition
Revive is a sugar-free BCAA formula built around the classic 2:1:1 ratio of L-leucine, L-isoleucine, and L-valine, designed to support muscle protein synthesis during training. Enriched with a potent antioxidant and recovery complex, Revive helps boost strength, endurance, blood circulation, and nutrient transport — making it a versatile option for any training style or athletic goal.
4. Hydration
Hydration is the most underrated part of any stack. Even mild dehydration can impact performance, focus, and recovery — yet most people don't think to supplement for it. An electrolyte formula helps replenish the minerals you lose through sweat so you can maintain peak performance throughout your session and recover faster afterwards.
Hydration+ by Applied Nutrition Professional
Hydration+ is a unique electrolyte and vitamin powder delivering 1,190mg of electrolytes per serve to support optimal hydration, combat fatigue, and maintain energy levels throughout the day. Suitable for vegans and vegetarians, halal-certified, and versatile enough to use during training, travel, or your everyday routine. Simply mix one scoop with water to stay replenished and on top of your game.
Putting It All Together
A well-rounded stack doesn't need to be expensive or complicated — it just needs to cover the basics. Start with a quality protein, add a thermogenic or fat burner that suits your stimulant tolerance, support recovery with a solid amino acid formula, and keep hydration locked in with an electrolyte product.
Mix and match from the options above based on your goals and budget. Whether you're cutting, maintaining, or building — these four categories form the foundation of a stack that actually works.
