Some dietary supplements are intended to assist you in more ways than one. Therefore you should take the time to consider the type of assistance you need, whether it be with fat loss, muscle building, endurance levels, or weight management, before you choose any specific product. In this piece, we will help you become better acquainted with BPI B4, which is one of several supplements offered by BPI Sports. According to BPI, this supplement is available in super capsules, which probably means the capsules are large. As for the cost, BPI B4 sells for anywhere from $27 to $50 through online stores.

Product Features

BPI B4 is essentially marketed as a supplement for fat loss and enhanced workouts. In other words, this product may help improve your performance, while reducing your weight. One capsule is a serving, and it should be taken 20-30 minutes prior to working out. If you are not working out, take BPI B4 in the morning or midday. According to the website, this product is high-end and dual-performance. Unlike many weight loss pills, this supplement is mostly geared toward guys.

Some of the notable ingredients used in BPI B4 are Caffeine (a stimulant and diuretic that ignites energy levels), Yohimbe Bark (aids with fat loss), Red Wine Concentrate (contains antioxidants and may support heart health), Sophora Japonica, Psoralea Corylifoia, and Dendrobium Nobile. This product is not suitable for those under the age of 18, and it is not okay for women who are pregnant.

  • Some interesting ingredients are used in this weight loss formula.
  • BPI B4 only needs to be taken once each day, one capsule.

  • You might experience some side effects when taking BPI B4.
  • There is no mention of a 100 percent satisfaction guarantee with this diet product.
  • This supplement may cause sleeplessness when taken late in the day.


It is unclear what makes BPI B4 so “effective.” While this supplement does contain caffeine to boost energy levels and stimulate the metabolism, most of the other ingredients are not elaborated on. This factor alone is enough to deter some dieters. On a separate note, it is obvious that BPI B4 is intended for men who exercise regularly. This is why this supplement is for improved endurance and performance levels.

    I was given B4 sample by a GNC store manager. I am a nurse and work 12 hour shifts, so I am frequently exhausted. I took this and was so sick. I usually drink 3-5 cups of coffee per day, so I ruled out caffeine sensitivity. I was so nauseous, my heart rate was in the 120’s, I was flushed and sweating through my scrubs. My pupils were dilated and I was shaking. I actually had to leave work. I was sick all day long. I noticed when I read other reviews, most positive comments were from specifically men that have used workout stimulants before. I did read up on the ingredients, and the dendrobium works like, and has a similar chemical composition of amphetamines. Just a word of advice from a naive, had to learn the hard way this time girl; not everything from a health food store is safe. Know what the ingredients are and what their mechanism of action is before taking an supplement.

    I have started to use this product 5 days ago and I am losing about a pound of weight each time I go to the gym. I don’t think that people will have the same results as me I am an advanced lifter and have a lot of muscle and I think it’s helping with the weight loss but I had belly fat I could not get rid of and I’m becoming very lean. I am very happy with the results. I will post back when I have reached the 2 week mark or until all b4 has been taken

    I was given a sample at GNC. I am 62 y/o . I took it in the morning. Within 2 hours I became extremely tachycardic and light headed & sweaty. I felt nauseated. This is a supplement which should not be taken w/o proper warning . I almost went to the hospital thinking something was terribly wrong. I was glad I did not go to work out!

    I have recently went to my GNC store and talked with a associate there who recommended this for me to loose my belly fat that I can’t get rid of while working out. I’ve read that this is mainly used for men so I’m kind of wondering now if this is the right product for me. Can someone help



    Hello Jennifer,

    I’ve been taking the product for 5 days now and have notice a trimming of my belly fat. My love handles are disappearing and the stomach is smaller than before. But, I also take the nite fat burner and put on my elastic stomach support (the one I use when I work out) and I am looking better in my clothes….my stomach is not as obvious. Last thing, I stopped working out to see how good it actually works. I will give you an update next week. Good luck!



    just started on Saturday. will let people know in a few weeks.



    I’m 24 and getting married in a few months and want to lose the few extra stubborn pounds I haven’t been able to shed. My local GNC recommended this for me. However after reading side effects I’m apprehensive. I would love to hear everyone’s feedback on this product before I start taking it. Thank you.
