Phenbuterol is a dietary supplement that comes from MuscleMeds Performance Technologies and is marketed as a fat burner. On the box it says that it is a “Maximum Strength Fat Burning Catalyst”. Although on the official product website it states that “Phenbuterol is a trade name and is not intended to depict any comparison to any pharmaceutical or other product of any particular benefit thereof”, the “Phen” in “Phenbuterol” was clearly selected in order to capture the attention of consumers in search of alternatives to the prescription diet drug Phentermine.
The makers of Phenbuterol claim that this product provides advanced fat burning technology by activating UCP-1 (Uncoupling Protein 1). UCP-1 supposedly boosts fat burning in brown adipose tissue. It achieves this result by carrying fatty acids from stored body fat into the mitochondria. This produces heat and activates a process known as thermogenesis. Thus, instead of utilizing ATP (Adenosine triphosphate) from muscle tissue, it uses fatty acids from stored body fat. According to the manufacturer, it is the brown adipose tissue and the fat burning mechanism of UCP-1 that is the prime benefit of Phenbuterol.
The ingredients in the formula include: Caffeine Anhydrous, Ilex Paraguariensis Leaf Extract, Grains of Paradise Seed Extract, Rauwolfia Serpentia Extract, and Advantra Z, which is comprised of Citrus Aurantium Extract, N-methyltyramine, Octopamine, Hordenine, and Tyramine.
Although the official product page goes into detail about the “science” behind the fat burning formula, provides several references to studies, and gives basic details about the different product ingredients and how they supposedly help to burn fat, there is not enough clinical evidence to support the claims that have been made about the effectiveness of ingredients.
In addition, the manufacturer does not list any side effects. However, considering some of the ingredients within this formula, the risk of adverse effects is possible. For starters, there is caffeine, which is a stimulant that is associated with side effects that include, but are not limited to: restlessness, insomnia, anxiety and nervousness. Caffeine may also increase heart rate and blood pressure in some people. Furthermore, Phenbuterol contains Citrus Aurantium, also known as bitter orange or synephrine. When combined with caffeine it can increase the risk of serious side effects, such as fainting, cluster headaches, high blood pressure, strokes, and heart attack.
Prior to taking this dietary supplement, it is strongly recommended that you first consult with your medical practitioner to make sure it is the safe and right choice for you.
