Fastin-XR is a nonprescription weight loss formula that markets itself as the “King of Stimulant Weight Control Formulations.” It is based on an original formulation that has since been updated in order to become even more effective, according to the official website claims. The product is designed to be taken for an all-day extended release. This may be appealing to dieters who don’t want to have to take more pills at every meal and who would prefer to keep their dosages to a minimum number of times throughout the day.
The official website of the manufacturer, Hi-Tech Pharmaceuticals, calls this product the “Strongest and most technologically advanced diet aid ever developed.” That said, as dramatic as all the claims may be on the website, and as much as they are made repeatedly throughout its description, no studies of any kind are cited to support these statements. If research has been conducted and published in a peer-reviewed medical journal, no mention of it was made on the official website.
This suggests that the product has not been researched as any company that has gone to the time and expense to hire an unbiased organization to conduct the investigation and publish it would flaunt such reputable evidence. This suggests that there may not be much to the Fastin-XR claims other than a motivated marketing strategy.
That said, just because there isn’t any science behind the product, it doesn’t necessarily mean that it won’t work. It does, however, mean that there isn’t any proof that it works. It also means that there isn’t any real way to know what the ideal dosage should be, whether or not there are side effects, or whether it’s possible for the ingredients to be toxic beyond a certain amount or if used for too long. It does leave a certain amount of risk on the side of the consumer.
At the time of the writing of this review, the Fastin-XR ingredients were: senegalia berlandieri leaf extract (containing phenylethylamine alkaloids including methylsynephrine, N-methyl-B-phenylethylamine, N, N-dimethylphenylethylamine, phenylethylamine), synephrine HCl, theobromine, green tea leaves, isopropylnorsynephrine, naringen fruit, 5-methoxytryptamine HCl and yohimbine HCl.
At first glance, certain red flags should raise when looking at this ingredients list. It is packed with powerful stimulants, as the marketing suggests, but it also combines substances that the FDA has recommended – even warned – against using. It contains ingredients that have both synephrine and caffeine in them. The FDA has warned consumers not to use diet pills combining those two stimulants as it increases the risk of heart attack and stroke, among other dangerous side effects.
