Phenastin is a non-prescription diet pill that you might come across if you are in search of a Phentermine alternative. While it is not truly an OTC alternative to phentermine, it does claim to be a “pharmaceutical grade weight loss stimulant.”
The product comes from Phenastin Clinical Weight Loss Solutions and supposedly provides benefits, such as reduced appetite and cravings, increased thermogenesis as well as improved energy levels and mood via its rapid acting and releasing caplets. When this Phenastin review was written, the product could be purchased on Amazon for $36.99.
Furthermore, at the writing of this review, each Phenastin white and blue speckled caplet contained 425 mg of the PHENASTIN 425 blend: Caffeine Anhydrous, Theobromine Anhydrous, Phenethylamine Hcl, 5-hydroxytryptophan (5-HTP), Mentha Piperita, Alpha Yohimbine.
Each of these ingredients can be found in many dietary supplements developed to support weight loss. Caffeine can boost mental alertness and is believed to also enhance energy and reduce appetite. Theobromine may increase metabolism and boost energy levels. 5-HTP is thought to help reduce appetite and is also believed to inhibit the intake of calories from carbohydrates. Alpha yohimbine is thought to help in the suppression of appetite.
All that said, only caffeine’s ability to boost mental alertness has ever been proven by clinical research. The rest of the claims made about these ingredients regarding their ability to help with weight loss are not scientifically proven fact. This means that taking this product will not necessarily lead to weight loss.
As for side effects, due to Phenastin containing stimulants, there is a risk of certain unpleasant effects, such as difficulty sleeping, sleeplessness, restlessness, jitters, anxiety, rapid heartbeat, headache, upset stomach, etc.
The suggested use is to take 1 caplet in the morning and 1 again with lunch. Users are cautioned not to take Phenastin late in the evening to avoid sleep disturbances as this product does contain caffeine. Additionally, users are instructed never to take more than 1 caplet at a time and not to exceed more than 2 caplets in a 24-hour period.
It should also be noted that this product has been developed to be used in combination with a healthy calorie-reduced diet and regular exercise, for optimal results.
While you may be interested in obtaining a stimulant diet pill, play it safe and make certain that Phenastin is the right choice for you. Consult with your healthcare provider before taking this product and/or making it a part of your weight management regimen.
