Xtinguisher is a supplement formulated and sold by Max Muscle. Max Muscle is a vitamin company with stores across the United States, though franchises are limited. The supplement is designed to support muscle growth and replenish energy to the muscle. The ingredients are commonly used in workout shakes, so there is nothing new or exciting about this product. Max Muscle formulates all supplements in-house. This means the products are unique, but the ingredients are likely used in supplements by other companies.

Xtinguisher contains no ingredients to promote metabolism or weight loss. It does support ATP production, which may affect energy levels on a muscular level, but that is not the same as boosting metabolism. The effect of this product on muscle product will depend on the intensity of workouts and diet, just like any other supplement.

List of Ingredients

Beta Alanine, L Histidine, L Citrulline Malate, L Taurine, L Aspartic Acid, D Ribose, Magnesium and Vitamin C.

Product Features

The ingredients in Xtinguisher are not listed in label format, so there could be some other ingredients the company has not listed in the product description. The Max Muscle website is a hard to navigate. Searches for Max Muscle products often return articles or blogs pertaining to the supplement. The reader must visit the official website and search for the supplement directly to purchase. Most Max Muscle products, including Xtinguisher, are available for sale online.

The product description gives the reader a bit of information on each ingredient. Beta Alanine buffers muscles and promote carnosine production, as does Histidine. Citrulline malate supports energy production in the muscle.

In the product description, we find a brief mention of creatine monohydrate. This ingredient is not listed on the main ingredient list, but we are not surprised to find it in Xtinguisher. Creatine monohydrate will cause weight gain and bloating. Muscle cramping is another known side effect.

Xtinguisher is not a new supplement. Max Muscle just placed a great name on a creatine supplement with beta alanine and a few other ingredients. This product is for bodybuilders or athletes in the off-season, not for dieters. The supplement will cause hydration of the muscle, but that hydration also causes water retention and weight gain.
