Nutrition Label and Ingredient Transparency

C4 Extreme Energy by Cellucor Product Label

C4 Extreme Energy lists the amount of 69% of its ingredients. It contains 16 ingredients. Out of those, 11 are listed with amounts while 5 are listed without amounts. The chart below illustrates how many ingredients in C4 Extreme Energy are listed with amounts. Green represents ingredients with amounts while red represents ingredients without amounts. The more green, the better.

Many supplement manufacturers hide the amount of a certain ingredient under the guise of a great sounding proprietary blend such as "Maximum Muscular Size Enhancer" or "Anabolic Cell Strength Matrix."

The amount of each individual ingredient included is hidden from the label making it impossible to know what's actually in the product you're using. Companies have the ability to mix costly and effective ingredients with cheap and ineffective ingredients making it difficult to tell which one is actually in a product.

Products with high percentages of ingredients without amounts are hiding the true nature of their effectiveness. Ideally, a product should list amounts of 100% of the ingredients they are using.
