ARTG listing means every claim is backed by science. When you’re comparing a “sports cream,” the most useful part of the label is often the line people overlook: the AUST L number. That number means the product is a listed medicine in the Australian Register of Therapeutic Goods (ARTG). Listed medicines must meet quality and safety standards and can only advertise product claims that are supported by clinical or scientific evidence. Furthermore, products must be manufactured in facilities that abide by the Australian Good Manufacturing Practice (AUS GMP). In reality, this matters more than clever marketing. It means products that can claim exactly what it’s proven to do. It also means customers get clear directions for use, written in a language for the public and not for lab benches. For RYGG and for our founder, orthopaedic surgeon Dr. Steve Andrews, this framework is non‑negotiable: product efficacy comes first, and advertising language must be honest. ARTG listing strips away marketing hype and highlights the true potency of our products. Brands are built on choices. RYGG began with a clinical one from our founder: put product efficacy first. That is why our claims are grounded in the Australian Register of Therapeutic Goods (ARTG), and our products are certified by Informed Sport. The goal was never to dazzle; it was to deliver warmup and recovery tools that work in busy lives. HEATE™ is used before activity to improve muscle performance, endurance and stamina. KHULE™ is used after activity to assist recovery and relieve mild joint inflammation. Dr. Steve Andrews brought surgical discipline to product design and Rygg’s advertising language. ARTG listing ensures claims are evidence‑anchored and consumer‑appropriate. Informed Sport certification adds every‑batch analysis and public verification. The result is a warm‑up performance cream and a cool-down recovery gel people can trust. Efficacy, not hype, is the organising principle at RYGG. How do HEATE and KHULE work The biological mechanisms that support performance and recovery Used together, RYGG’s HEATE™ thermo performance cream and KHULE™ cryoactive recovery gel create your end‑to‑end performance and recovery regime. HEATE™ prepares muscle groups, supports increased blood circulation and provides anti‑inflammatory support. KHULE™ delivers fast‑acting cryotherapy‑like cooling to help calm the body and support post‑exercise recovery. Together, they provide a practical, science‑aligned protocol. At a sensory level, these effects align with the behaviour of TRP (Transient Receptor Potential) ion channels in the skin and peripheral nerves. Menthol is a classic agonist of TRPM8 (Transient Receptor Potential Melastatin 8), a cold‑sensitive channel whose activation is associated with the perception of cooling. This cooling input is linked to downstream vasoconstrictive responses that can help manage post‑exercise intramuscular stress and transient joint swelling—think of KHULE as an ‘ice bath in a bottle’ used within the product’s directions. By contrast, warming actives such as methyl salicylate can activate TRPV1 (Transient Receptor Potential Vanilloid 1), a heat‑sensitive channel associated with warmth perception; TRPV1 activation is consistent with local vasodilatory responses that accompany a feeling of heat. In HEATE, that fast‑onset warmth helps prime primary movers and prepare joints for activity. Beyond sensation, methyl salicylate also provides anti‑inflammatory support, rounding out HEATE’s role as a pre‑sport ritual. How to use HEATE and KHULE HEATE — Application guidance Apply an ample squeeze of HEATE 15–30 minutes pre‑sport or exercise to large muscle groups that will be active. Target areas: quadriceps, hamstrings, calves, glutes, lower back, shoulders and forearms (for grip‑intensive tasks). Rub the cream into muscles until it is no longer visible, then wash hands immediately after. Shop HEATE KHULE — Application guidance Apply KHULE™ to trained muscles or areas of the body experiencing discomfort (for example, quadriceps and calves after running; shoulders and elbows after overhead work; knees and ankles after field sessions). Massage the gel into the area until absorbed. Wash hands afterwards and reapply as needed according to the label. Shop KHULE Sources & further reading Therapeutic Goods Administration.

From warm up to recovery, batch codes keep your routine transparent and safe. Clean sport depends on clean products. That sounds obvious until you’re standing in a doping‑control station or a workplace testing bay and someone asks, “What exactly went on your skin?” In a market crowded with badges, only a few marks mean what professionals think they mean. Informed Sport certification is one of them. It’s not a loose “quality” logo; it is a program built for sport and high‑compliance environments that requires every batch of a certified product to be analysed for banned substances in ISO/IEC‑accredited laboratories before release. Crucially, the batch number printed on your tube links to a public record you can look up in seconds. That traceability protects athletes who live under strict liability, and it protects first responders, defence personnel, and industry workers subject to routine screening. If you use topical sports products like performance cream for warm‑up, muscle rub for activation, recovery gel after training, then batch testing is the difference between confidence and guesswork. With RYGG, both HEATE™ and KHULE™ carry Informed Sport certification and are listed medicines in Australia’s ARTG, so the claims you read are backed by science, not marketing hype. This article explains how to tell a robust certification from a look‑alike, how batch testing differs from occasional auditing, and why a simple verify‑document‑use workflow belongs in your kit policy. We’ll show you where to find a batch code, how to record it, and how to align your warm‑up cream and recovery gel choices with clean‑sport standards without adding friction to busy days. The outcome is practical: you reduce contamination risk, you answer questions with evidence rather than memory, and you keep focus on what matters; performing well and recovering fast with products you can trust. Informed Sport certification is built around ISO 17025 laboratories and documented methods. Every batch analysis is linked to a batch code printed on the tube so you can match product to lab record. Public batch verification makes audits simple for teams, coaches and compliance officers. If you cannot verify a batch, you are carrying unnecessary risk in a high‑compliance environment. Batch‑tested topical products reduce the chance of inadvertent contamination from banned substances. For athletes under strict liability, the safest path is to use products with every‑batch testing and keep a usage log. First responders and defense members who face internal testing benefit from the same discipline. Industry workers can use batch verification as part of a safety management system. HEATE™ and KHULE™ carry Informed Sport certification and are batch tested prior to release. The combination of ARTG listing and Informed Sport creates a clear, evidence‑led trust chain. Clean‑sport culture values procedure more than promise, and batch codes make procedure visible. When a label uses vague language like 'lab tested' without batch detail, treat it as insufficient for sport. A real certification program provides searchable records, explicit scope and ongoing oversight.

TRPM8 (Transient Receptor Potential Melastatin 8) is an ion channel predominantly involved in sensing cold temperatures and cooling agents like menthol. Belonging to the TRP (Transient Receptor Potential) family of ion channels, TRPM8 is expressed in sensory neurons and various tissues, including the skin, prostate, and bladder. This channel is activated by temperatures below approximately 26°C (78.8°F) and by chemical stimuli such as menthol and icilin. Upon activation, TRPM8 allows the influx of calcium (Ca²⁺) and sodium (Na⁺) ions into the cell, leading to depolarization of the neuronal membrane and the generation of action potentials. These signals are then transmitted to the brain, where they are perceived as a sensation of cold. This mechanism plays a crucial role in thermoregulation and the sensory perception of temperature changes. In addition to its role in cold sensation, TRPM8 has been implicated in various physiological and pathological processes. It is involved in the regulation of bladder function, and its expression levels have been linked to certain cancers, particularly prostate cancer, making it a potential therapeutic target. Research on TRPM8 continues to uncover its diverse functions and potential applications in medicine, including pain management, cancer treatment, and the development of cooling agents for therapeutic use.

For athletes, socks are not just a minor accessory but a critical component of preparation for training and play a significant role in performance, comfort, and injury prevention. 1. Moisture Management: Athletic activities cause feet to sweat, and moisture can lead to blisters, infections, and discomfort. High-quality athletic socks are made from moisture-wicking materials that draw sweat away from the skin, keeping feet dry and reducing the risk of blisters and fungal infections. 2. Cushioning and Impact Protection: Athletic socks provide extra cushioning in high-impact areas such as the heels and balls of the feet. This cushioning absorbs shock, reduces stress on the feet, and prevents injuries caused by repetitive impact, which is crucial in high-intensity sports like running, basketball, or soccer. 3. Improved Fit and Support: Well-designed athletic socks enhance the fit of sports shoes, providing additional support and reducing the chances of shoes rubbing uncomfortably against the skin. Compression socks, in particular, improve blood circulation, reduce muscle fatigue, and support recovery by applying gentle pressure to the legs and feet. 4. Temperature Regulation: Athletic socks help regulate temperature, keeping feet warm in cold conditions and cool in hot environments. They achieve this through the use of advanced materials that provide insulation and breathability, ensuring optimal comfort during various weather conditions. 5. Injury Prevention: Specific designs in athletic socks, such as arch support, reinforced heels and toes, and compression zones, contribute to stability and support. These features help prevent common injuries like sprains, strains, and plantar fasciitis by providing proper alignment and reducing excessive foot movement. 6. Hygiene: Athletic socks play a crucial role in maintaining foot hygiene. By absorbing sweat and preventing it from accumulating in shoes, they help reduce foot odor and the risk of infections. 7. Psychological Boost: Wearing the right gear, including socks, can provide a psychological boost to athletes. Knowing they have the proper equipment can enhance confidence and focus, contributing to better performance. For athletes, socks are essential for moisture management, cushioning, support, temperature regulation, injury prevention, and hygiene. They are an integral part of athletic gear that significantly impacts performance and overall foot health.

Sleep, often overlooked, is a critical component of overall health and well-being. It’s not just about feeling refreshed - it’s about giving your body the time it needs to repair and rejuvenate itself. When we sleep, our bodies enter a state of restorative calm. This is when the magic happens. Our muscles repair, our brains process the day’s events, and our immune system strengthens. It’s a time of healing and growth. Research shows that lack of sleep can lead to a host of health issues, including weakened immunity, increased stress levels, and even weight gain. It can also affect our mood, memory, and cognitive function. For athletes and fitness enthusiasts, sleep is even more crucial. It’s during sleep that our bodies produce growth hormone, which aids in muscle repair and growth. Without adequate sleep, our bodies can’t fully recover from the stresses of exercise. In conclusion, sleep is not a luxury, but a necessity. It’s an essential part of our body’s recovery process. So, prioritise getting a good night’s sleep - your body will thank you! Remember, quality sleep is just as important as diet and exercise in your health and fitness journey. Don’t neglect it! Sleep well, recover better.
