Zombie Labs have been making waves in the supplement industry in 2025, with the release of the strongest pre-workout in Australia, End of Dayz. What goes up, must come down. Enter Blackoutz, a sleep formula that makes sure that you can kick back, unwind and get some sleep after those sessions where the strongest pre in Australia is the only thing that will cut it. Product Breakdown When you think of sleep supplements, your brain probably goes to melatonin and/or magnesium. Those ingredients definitely help in a sleep support supplement, however, adding in ingredients that help with relaxation, unwinding and getting you to sleep across multiple pathways is really what makes the difference. Each 10 g scoop includes: L-Glycine (3000 mg) A nice clinical dose of L-glycine to promote a deeper and more restorative sleep, as well as assist with your body temperature. Magnesium Citrate (2000 mg, providing 320 mg magnesium) Naturally, you’d see a decent hit of magnesium in a sleep supp. Helping your nervous system calm and reducing muscle tension. Myo-Inositol (1000 mg) Balancing neurotransmitter signalling and reducing feelings of stress, A 1000mg dosing of Myo-Inositol will support a calm mental state before bed.

Lemon Balm (500 mg, providing Rosmarinic acid) Easing tension and stress from the day, letting you transition smoothly into sleep. California Poppy (300 mg, providing Protopine) A natural alkaloid with sedative properties. Aiding relaxation. Chamomile Flower (100 mg, providing Apigenin) You can’t have a sleep supp without Chamomile. Known to help calmness and rest. Green Tea Leaf (100 mg, providing L-Theanine) You’d probably find this in a pre-workout. Here it takes a different role, helping with relaxation without being paired with caffeine. Griffonia (100 mg, providing 5-HTP) A direct precursor to serotonin and melatonin. Helping balance your mood and regulate your sleep. Vitamin B6 (3.2 mg as Pyridoxal 5-Phosphate) Supports the conversion of 5-HTP into serotonin and helps regulate brain activity. Vitamin C (80 mg as Sodium Ascorbate) Provides antioxidant support while contributing to overall wellness and recovery. BioPerine® (5 mg) A patented form of piperine that enhances nutrient absorption, making sure you get the most out of the formula. It’s clear that a lot of thought went into this sleep formula. Making sure that your body unwinds and relaxes, before helping you go to sleep. Formula Rating - 8/10 Ticking all the boxes for a sleep support supplement.

Sleepy Strawberry Kiwi: A refreshing fruity twist that balances sweetness with a gentle tartness, ideal if you prefer a lighter night time drink.

Navigating Creatine

As widely available and widely studied creatine supplements are in the fitness industry, there are always ways to make choosing a creatine supplement confusing and overwhelming. The benefits are easy to understand, so why shouldn't knowing what you’re looking for be easy too? Let’s go into the different variations of creatine and find what’s best for you. A Background On Creatine Creatine is one of the most researched supplements in the world, known for its role in improving strength, power, and muscle performance. It works by helping your muscles produce more energy during high-intensity exercise. Beyond performance, studies also show creatine supports muscle growth, recovery, brain health, and even endurance. Its safety and effectiveness are backed by decades of scientific research, making it a reliable choice for both beginners and advanced lifters. Creatine is proven to be a supplement with a multitude of benefits, and very low risk of side effects. Over the decades, many new types of creatine have been marketed as either more effective than the original, or a boosted version of it. Creatine Nitrate claims to be more soluble than the original, with its bond of nitrate being easier to digest. The same can be said about Buffered Creatine or Ethyl Ester, where taking it is an "improved" version of the original source, with various benefits mainly seen on a microscopic level. Two types however, stand out among the crowd as the most popular, and most effective. Creatine Monohydrate Creatine Monohydrate is the most researched and trusted form of creatine, known for its effectiveness, safety, and affordability. It has all the various benefits of creatine, while also supporting muscle growth and recovery. With decades of studies proving its benefits, and a price point much lower than newer alternatives, creatine monohydrate stands out as the best-value option for athletes, lifters, and anyone looking to improve performance. Creatine Hydrochloride Creatine HCL (Hydrochloride) is a newer form of creatine that’s praised for its superior solubility and easier digestion compared to monohydrate. Because it mixes well in water and is often taken in smaller doses, it’s a popular choice for those who experience bloating or stomach discomfort with other forms. While research on HCL is more limited, many people find it convenient and effective, though it generally comes at a higher price than creatine monohydrate. Wrapping Up The bottom line is all creatine generally is going to have a benefit on you, your performance and recovery. Taking monohydrate gives you the benefit of knowing what you’re taking is researched thoroughly, taking HCL gives you that same benefit, with the inclusion of people who may have issues digesting monohydrate. Always consult a nutritional specialist to see what the best version is right for you.

What Is A Calorie?

Whether it be dieting or exercising, having even a baseline understanding of what calories are and how they make up certain foods, is essential to achieve long term success with your goals. But what is a calorie actually? How much of these calories make up the macronutrients present in our everyday lives? Macronutrients & Calorie Density Firstly, it’s common knowledge that there are three main macronutrients that the body ingests and uses the nutrients from to run on a day to day basis. These macros each have a very specific role to play in the body’s functions, and all have different caloric amounts; Carbohydrates - 4 calories per 1g These are the body's primary source of energy. When consumed, carbs are broken down into glucose, which is used by the body for fuel. Carbs also play a role in the storage of energy in the form of glycogen, which can be accessed during physical activity. Fats - 9 calories per 1g These are made up of fatty acids and glycerol that are essential for many vital functions. Fats help absorb fat-soluble vitamins (A, D, E, and K), support cell structure, and protect vital organs by providing cushioning. Additionally, fats are involved in hormone production and help regulate body temperature. Proteins - 4 calories per 1g These are made up of amino acids, which are the building blocks of the body. They play a crucial role in repairing and building skeletal tissue, skin, and organs. Proteins are also important for producing enzymes and hormones that regulate several bodily functions, including metabolism and immune response. Foods found at the supermarket, made at home and bought out, are made up of these macronutrients, the macros you’re eating all have a caloric amount. Therefore, when you meal prep and have a high protein meal for example, it tends to be lower in calories because you may not cook the chicken with oil, or you’ll have extra vegetables instead of extra rice, you’re digesting macros with a better calorie to gram ratio and being more conscious of how the food is cooked. Pretty Obvious Right? Most of this information is readily available, and if you’ve progressed from being a novice in gym, you’d have an understanding of how those calories are burnt off in the same way. What’s important to remember though, is that a reminder can go a long way. If you’re struggling to lose weight for example, and you’ve prepared meals all week, not eaten out and stayed super strict on your diet, but you’ve stayed the same weight or maybe even gained, it may be because of the process you’re cooking your food in. The Bottom Line All in moderation and with balance is a very popular saying right now within lifting and dieting circles, it couldn’t be more true. At the end of the day, this information isn’t to ward yourself off of certain foods, but to become more aware of the processes and ways you can enhance your training and overall quality of life. There’s no need to remember how many calories a teaspoon of oil is or the grams of avocado on your toast, but be conscious of your goals whenever the opportunity comes.
