Some Quick Information On This Product & Company

Phentaslim is a weight loss pill produced by a US-company named Optimum Nutra Inc. When diving into the background of the company, it seems they have been operating for several years and have amassed quite a positive reputation in the industry for producing high quality products. The product costs a reasonable $52.99 and will last users approximately 30 days.

Consumers of Phentaslim are promised effects such as boosted energy levels, an elevated metabolism, the increased ability to burn body fat and suppressed appetite levels.

Does Phentaslim Work?

Based on our research used in the Phentaslim formula, we firmly believe that this is a fat burner that will deliver weight loss results for users. The product contains a complex of clinically proven fat burning ingredients that will help boost your metabolic rates, meaning your body will start burning calories at an accelerated rate (leading to rapid weight loss).

Furthermore, the product contains ingredients that are very useful for appetite control – we expect that the average Phentaslim user will experience appetite suppressant effects, which will help to lower your daily caloric intake.

Another benefit to Phentaslim is that it can help reduce your perceived rate of exertion (RPE). If you’re an avid gym-goer, taking the product prior to your workouts is likely to significantly improve your performance.

I ordered this product mid-April and am really liking it so far! Have lost noticeable weight (that people comment on). I do exercise regularly anyway so haven’t changed anything there, it’s just given me a much needed boost. The only thing I will say is that – as a big caffeine drinker myself – do not drink coffee while taking this product, at first I couldn’t sleep/was feeling a bit jittery. However when I cut the coffee down that all stopped! Good product if taken correctly!

I received my order in the mail super fast which was awesome. Best of luck to everyone who takes these, they’re great!
