I-Force Dexaprine Ingredient Write-Up.

Figure 1: I-Force Nutrition's
newest fat burner Dexaprine
Just received an email from the marketing guys @I-Force Nutrition informing me that "Dexaprine is finally here...". Well, to be honest, I had not been waiting for it, but the email intrigued me and I would like to give you a brief rundown on the ingredients, which are "guaranteed to give you more energy, increased appetite suppression, and insane mood enhancement than you have ever experienced!" - I don't know about you, but I think I have heard similar claims before ;-)

Ok, here we go: One bottle of Dexaprine, which is 39.99 (pre-order offer @ I-Force webshop) has 60 servings (serving size 1 capsule) of the "thermogenic powerhouse" (I love these advertisment guys) @ 600mg of the following ingredients
  • Thermophoric Amine Mood Enhancing Complex,
    which is basically just synephrine (from citrus aurantium) + geranamine (which is also known as 1,3-dimethylamylamine, 4-methyl-2-hexylamine, or as I-Force has it on the label 1,3-dimethylpentylamine)
  • Extended Release Energy Complex,
    which is a combination of caffeine and theophylline, with the latter having identical beneficial (stimulant, beta receptor agonism, etc.) as well as detrimental (e.g. temporary insulin resistance in muscle tissue, cf. Colnes. 2010, adrenal problems due to long term (over-)use etc.) effects on perceived energy and weight loss, but a longer half-life, which is even prolonged by the concomittant admistration of caffeine (Jonkman. 1991)
  • Anabolic Protein Synthesis Enhancing Complex,of which I think that it is completely mislabeled, because it is a combination of the two diiodo-L-Thyronines (also known as T2s), 3,3'-T2 and 3,5-T2, of which I have already written in a paper for a German BodyBuilding and fitness magazine (click here for Google-translation) that their impact on metabolic rate (in non-hypothyroid individuals) is probably negligible and would - according to the mice studies that are presently available - require much higher doses than those present in current "thyroid stimulating" products to up-regulate UCP significantly above "normal" levels.
So, overall this does leave us with a probably relatively long lasting stimulant that will enable you to work harder and thus burn more calories and subsequently more fat. Not bad, but nothing new or even revolutionary here.

On a side note: As it is quite often the case in the supplement industry, Dexaprine is deliberately named to sound similar to a potent drug, the synthetic amphetamine Dexedrine (has up to 15 mg dextro-Amphetamin per cap). This practice is about as shabby as calling a product XYZ-"drol". The latter, i.e. the "drols", have incidentally been banned by bodybuilding.com - good idea, guys ;-)
