While many assume all C4 products contain the same ingredients, the ready-to-drink C4 energy drinks do not have creatine in them. This key muscle-building ingredient is typically reserved for C4's powdered pre-workout supplements, so checking the label to differentiate between product lines is crucial.

According to user reviews and manufacturer information, a primary and expected sensation of the C4 energy drink is a tingling feeling, known as paresthesia, which signals that its beta-alanine is working. Following this, users can expect a noticeable boost in energy and focus, which can help power through workouts or provide an afternoon lift.

In early 2025, C4 Energy's parent company, Nutrabolt, discontinued its official Skittles and Starburst flavor partnerships. This led to the introduction of a new, mixed-fruit flavor called Cosmic Rainbow, causing confusion among long-time fans who loved the original Skittles C4. While Cosmic Rainbow replaced the Skittles flavor in the product lineup, they are not the same product.

According to the brand's official website, the majority of C4's ready-to-drink (RTD) energy beverages are formulated with zero sugar, zero calories, and zero carbs. This commitment to a sugar-free profile is a cornerstone of their marketing, but the question remains: do all C4 energy drinks have zero sugar, or are there exceptions within their product lineup?

The amount of caffeine in C4 pre-workout can range dramatically depending on the specific product, with options containing between 135 mg and 300 mg per serving. This means checking the label is essential for managing your energy levels and ensuring you choose a formula that aligns with your tolerance and workout intensity.

According to the product's supplement facts, a single serving of C4 Original contains 1 gram of Creatine Nitrate (NO3-T®). This provides a lower dose of creatine compared to the widely-studied monohydrate form and raises questions about its effectiveness for muscle saturation.

With more than 2 billion servings of C4 products sold since 2011, many people turn to this brand for an energy boost. C4 Ultimate Energy, a high-stimulant version of their drink line, is often chosen for intense workouts or demanding tasks. However, before consuming, it's crucial to understand if C4 Ultimate Energy is safe for your individual health profile, considering its ingredients and potential risks.

The SKITTLES-flavored C4 energy drink delivers a substantial 200mg of caffeine per 16 fl oz can, designed for explosive energy. While the iconic SKITTLES partnership has been rebranded to 'Cosmic Rainbow,' the potent, zero-sugar formula remains largely unchanged, providing a significant boost comparable to two cups of coffee.

Creatine monohydrate is likely the most studied and universally accepted exercise supplement of all time, known for boosting strength and power output during high-intensity exercise. While many C4 pre-workout powders and some specific energy drinks incorporate this powerful ingredient, it's a common misconception that all products under the C4 brand include it.

Cellucor's C4 pre-workout has been a popular choice since its introduction in 2011, with billions of servings sold. Selecting the best C4 product depends on factors such as experience and training goals. This guide provides a detailed comparison to assist in choosing the ideal pre-workout.
