Even if Fat Smack is not the best supplement in the world, it has a great name. The official website for Purus Labs, the creator of Fat Smack, is very difficult to read. The ingredients are not listed in label form, so the dieter must search through the product description looking for all the ingredients. Some could be missing and the dieter would never know. The ingredients are listed with scientific names, in some cases, so the dieter may have trouble realizing if an ingredient is dangerous or associated with potential negative side effects.

Fat Smack contains caffeine, but the manufacturer does not reveal how much. This is dangerous as the dieter may be sensitive to large amounts of the stimulant. It is best to start supplements with an unknown amount of caffeine at the lowest dose to ascertain how the supplement effects the body before taking the full dose.

List of Ingredients

1,3,7-trimethylxanthine (Caffeine), 2-amino-4-methylhexane, Cissus Quadrangularis, Capsaicinoids, Vitamin and Mineral Matrix and Piperine.

Product Features

Caffeine is the first ingredient on the list. If it were the first ingredient on the label, we would know caffeine is added in the highest concentration, but the label is not available for viewing. Purus Labs does not bother to list how much caffeine, but they do refer to a clinical study on the effectiveness of caffeine; at least that is a step in the right direction.

The next ingredient is 2-amino-4-methylhexane. This ingredient is commonly known as dimethylamylamine and it is associated with negative side effects like heart palpitations. We do not support any supplements that contain this ingredient, especially when combined with another stimulant.

Cissus quadrangularis is an antioxidant. This ingredient does not affect weight loss or metabolism. Capsaicinoids is just a fancy name for hot peppers. This ingredient facilitates absorption of the other ingredients in the formula. The Vitamin and Mineral Matrix is unique because most fat burners do not bother to include vitamins. They are included in Fat Smack to support antioxidant effect. Piperine is black pepper and it is added for the same reason red pepper is added.

  • Ingredients are listed in the product description.
  • Includes caffeine, a proven fat burner.


  • Contains a stimulant associated with heart palpitations.
  • May not be safe for all dieters.
  • Antioxidants are not proven to affect weight loss or metabolism.


We are not thrilled with the ingredient list for Fat Smack, but we still love the name. Caffeine is a good start, but adding a dangerous stimulant into the mix is more than enough to give this product a thumbs down. Dieters also need an appetite suppressant, which is missing from this supplement.
