"Cellucor" is a well-known brand in the fitness and nutrition industry. They offer a range of products, including the popular C4 pre-workout and Cor-Performance Creatine. The Cor-Performance Creatine is described as a solid, run-of-the-mill option that mixes well and is affordable. It contains creatine monohydrate, which is linked to improved power output, greater muscle size, better muscle endurance, and possibly cognitive benefits. However, customer reviews on Trustpilot show mixed experiences. Some customers praise the products and customer service, while others report issues with customer service and side effects from the products. As with any supplement, it's important to consider individual tolerance and consult with a healthcare provider before use..
