The idea that fat burner pills can double up as a pre-workout energy boosting product is certainly nothing new – in fact, other than some small differences, the two types of product are very similar. Despite the obvious similarities, BPI are one of the first companies to release a self-proclaimed “fat burning pre-workout”.
In this B4 Thermogenic review, we’re taking an in-depth look into the formula to establish what we believe consumers can realistically expect from it.
Readers please note that statements on this page are fair comment based on observation. This content is produced on a matter of public interest.
What Is B4 Thermogenic?
B4 Thermogenic is a weight loss and pre-workout pill produced by a US-based company named BPI Sports. At the time of writing this review, BPI Sports having a 3-star rating on the popular customer feedback platform Trustpilot.
You can buy B4 Thermogenic at the BPI Sports website (www.bpisports.com). It is also available on Amazon and at various other online supplement stores.
One bottle of B4 Thermogenic contains 30 capsules, costs $19.99 and will last users for 30 days based on the directions of taking 1 capsule prior to your workout.
This product is targeted towards those who are looking to lose weight. Unlike most other conventional diet pills, BPI have essentially made this a 2-in-1 product; in buying B4 Thermogenic you’re essentially getting a diet pill and a pre-workout formula – while it is certainly not the most potent fat burner or pre-workout, it still does offer good value for money for those who are regular gym-goers looking to cut fat.
Consumers of this product are told that the product can help them burn their body fat, lower their appetite level and improve their energy levels.
Does B4 Thermogenic Work?
Based on our research into B4 Thermogenic, we believe that it may be useful for the purposes of weight loss if used correctly.
To set your expectations for this product, users should be aware that B4 Thermogenic does not contain any ingredients that will directly and independently “burn body fat” – we believe the product is best viewed as a “weight loss support pill”, rather than something that can quickly “melt away excess body fat” for users.
In order to see genuine weight loss results with this product, you’ll need to stick to caloric deficit diet for a period of 8-12 weeks.
While the product concept is a little unorthodox, B4 Thermogenic does contain some useful ingredients that can help boost your metabolic rates and improve your athletic performance.
With that being said, it’s certainly not the most potently-dosed weight loss pill we’ve ever seen, and it doesn’t contain a lot of the core ingredients that go into effective pre-workout products – in our opinion, B4 Thermogenic is a bit of a mediocre mishmash.
The main benefit users will get from this product is increased metabolic rates and energy levels. With an increased metabolism speed, your body will be able to increase the rate in which it burns calories (though you must remember that if you’re still consuming more calories than your body actually needs, you’ll continue to gain weight).
The bottom line is, if you’re willing to overhaul your diet and lifestyle, B4 Thermogenic may be a helpful little tool for achieving your goals (just remember, it’s not going to produce miracle-like results).

Our Final Verdict On B4 Thermogenic
To conclude our B4 Thermogenic review, it’s a bit of a mixed bag – there are things that we like about it and things that we aren’t too blown away by.
It is very interesting that BPI felt the need to combine a weight loss pill with a pre-workout, as typically weight loss pills are loaded with caffeine and stimulants anyway. Nevertheless, B4 Thermogenic does have something to offer those who are looking to lose weight.
BPI’s B4 certainly has the ability to boost your metabolic rates and energy levels. It can also trigger cognitive enhancement effects like increased focus and concentration – allowing for a great gym-session.
Like any supplement, B4 Thermogenic has its drawbacks. It contains a potentially unsafe stimulant named Yohimbe, which has some nasty possible side effects. It also will not directly and independently “burn body fat”.
The bottom line is, B4 Thermogenic is best viewed as a weight loss support supplement and should be used in such a manner. If you were hoping the product would deliver miracle-like weight loss results without changing your lifestyle or diet, you’ll be disappointed.
