PhD Fat Catalyst Review

Fat-Catalyst is a pharmaceutical strength fat burning product marketed towards users with a more athletic nature than the average dieter, but the blend appears not to contain anything that cannot be found in hundreds of other weight loss supplements so there is no reason it could not be used by the average Joe or Joette who needs to shift a few pounds and does not mind paying over the odds prices for a simple blend hiding behind a lot of technical jargon.

The product is manufactured by the Canadian company PhD Nutrition Ltd and sales are made via their company website and through several independent online stores including GNC and Although PhD’s company headquarters is located in British Columbia, Canada, they are only willing to ship to customers in the US. This hints that the main distribution center is probably located somewhere south of the Canadian border and the fact that all their preferred marketing partners appear to be based in the US and Canada suggests the company is concentrating most of its marketing efforts in those areas, so non-North American customers may find it difficult to find a supplier.

The Cons 

  • Some of the ingredients may be problematic

  • Rather pricey

  • Use of proprietary blends

Promised Benefits and Selling Points

In chemistry a catalyst is a substance that has the power to initiate or accelerate a reaction between two or more other ingredients and PhD have so named their product because they claim the formulation can initiate accelerated fat loss. They further claim that no muscle definition will be lost during the process. Other promised benefits include:

  • Maximized energy without the jitters
  • Increased epinephrine and norepinephrine
  • Increased stored fuel metabolism

Key Ingredients

PhD states Fat-Catalyst is ‘the most effective fat loss agent’ because it contains only ingredients that science can support, but the entire ingredient profile is incorporated in two proprietary blends so the inclusion rates are not known. If the quantity of any ingredient is insufficient it does not matter how good the ingredients are the formulation simply will not work.

Each capsule contains:

Blend 1: Phd Fat Catalyst Metabolic Intensifier (462 g)

  • Epigallacatchin 3-gallate (EGCG) (Green Tea Extract standardized to 50% EGCG/98%poly/80% cat), (EGCG):  Never before has such a vast amount of letters, numbers, and brackets been required to say green tea extract, but that’s the truth of the matter—it’s simple ol’ green tea, and green tea has a powerful reputation for encouraging fat burning, but its ability is not wholly supported by scientific evidence.
  • 1,3,7-trimethylxanthine:  Another very simple ingredient hiding behind a very grandiose-sounding name—it’s caffeine so it should provide some extra energy (if enough is included), but its inclusion also gives the blend the potential to cause caffeine-related side effects such as headaches, the jitters, and heart palpitations.[source]
  • Oleuropein Aglycone:  A dose of good, old, olive oil. Apparently incorporated here to initiate the release of the hormones epinephrine and norepinephrine. Many ingredients are said to possess this ability and are often incorporated in blends such as this to trigger a state of fight or flight that then has the effect of suppressing the appetite.

Blend 2: Phd Fat Catalyst Metabolic Extender and Hormone Trigger (292mg)

  • 4-Hydroxy-3-Methoxybenzyl 8-Methyl-Nonoate Ester (Sweet Red Pepper Extract [CH-19]): Another simple diet pill regular made to sound like something more technical than it is—red pepper extract. Red peppers contain a compound called capsaicin and several studies show it has the power to boost thermogenesis and power up the fat burning process, but only if included in sufficient quantity and the inclusion rate here is not known.
  • 4-(4-Hyrdroxyphenyl)-2-butatone (Raspberry Ketone):  Raspberry Ketone is a popular diet pill inclusion with an enviable reputation for encouraging fat burning. Initial interest in its fat burning qualities dates back to 1995, when Life Sciences published the results of a study conducted in Japan
  • 6,7 dihydroxybergamottin:  A component found in grapefruit juice. Some researchers are exploring the possibility that the ingredient may have the ability to encourage the easy absorption of nutrients, but 6,7 dihydroxybergamottin can interact badly with some medications.[source]

[info]Usage Instructions

One capsule should be taken each morning 30 to 60 minutes before a workout session. If desired a second capsule may be taken in the early afternoon.[/info]


Prices can vary a little from one supplier to the next, but the average retail price is usually about $50 for a bottle of 60 capsules.
