This product really give you the boost that you are looking for . I have a month already using the product before my training. And the boost that I have during my workout is amazing. I train dayly basis betwen 2 to 3 hours , am hours. Usually 12 am to 3 am . I have so much energy that I really have to control on my repetitions. And the burning fat really works. Also I have my self a diet high in protein high in fiber but low on calories. In my case I am a big guy 295 pound 5' 11" so my diet no necesary will be yours. The product works really good but is not magic. Try to add a diet adapted it for what are YOU looking for and overall training training. It is a waist of time if you take the pill but not train. Because you need to burn that over energy you have. The only reasson that I dont give a 10 is because I am very acceptable on caffeine caffeine dont.bother to me at all. But I know that it all cases is not the same. Many people are suceptible to caffeine. Overall for me exellent I will keep using it.

Didn't notice any change in appetite or really any benefits of this product. Could have been user error, but I followed instructions and just didn't see any change.

This pill was horrible, I took it as directed and it made me feel awful. I became so hot and itchy and sick to my stomach. My resting heart rate rose to almost 100for several hours and I became seriously worried and short of breath. I would but recommend this to anyone under any circumstances.

My friend recommended this product to me so I tried a sample. I took one pill at 12 noon, 30 minutes before my workout as instructed. I got the shakes mid way through my workout and felt terrible by the end of it. I was shaky the rest of the day. I went to bed at 11 pm and did not fall asleep until 4 am. I felt wide awake. I won't be using this product anymore and have gone with a different fat burner.

I've been looking for a thermogenic powerful enough to take just once a day but did not give me the jitters. This is it. Very safe product and a good value. Don't take it (or any thermo) thinking that it's a magic pill. It works best as a part of a fat loss stack along with BCAAs, protein powder and good, clean nutrition plan. I plan to purchase again.

Please help me… I’m using this product for 4 days now. My workout starts at 5:30pm and then I can’t sleep at night. Will it’s still work if I take it in the mornings and do my workouts at night?

I felt the product did what it said it would do.

I take this every morning on an empty stomach before work and class. I have noticed good energy in the mornings and a positive mood. As a fat burner I wouldn't really recommend this, I think the only reason I would buy this again is because of the nice energy and positive mood it provides and you can stack this with your pre-workout. If you are looking to "shed fat" look into other products or focus on your diet and exercise.

Been taking for two weeks now. Not enough CNS stimulation to make me jittery. Improves my energy a ton for early morning workouts (almost everyday thanks to work). I love the product. I think it's important to note two things: (1) You can take the product for an extended period without having to time rest weeks in every two months. Right away that tells me the stuff is a little less toxic, maybe a little less habit forming, but reliable. (2) It doesn't have so much caffeine and other fast acting stimulants that you can't stack it. I take before breakfast w/ a half-scoop of preworkout after my first meal prior to working out (30min later than the manufacturer 'ideal' workout window, but that's ok).

B4 Thermogenic, by BPI Sports. Here's my take on this stuff. If you want to take this for fat loss - honestly, I can't say this stuff helps. How would it even be possible to know? I'm already exercising and dieting. If it does help, the impact for me was negligible. However, as a "mood lifter" - I do notice that I'm more....1) willing to workout 2) Nicer to the people around me 3) have slightly more ...enthusiasm that I normally do. In that context, it can impact - but not because it's burning calories while I sit in front of my computer screen and type this out. Is that what I thought it would do? Nah. But, I figured every teeny bit would help. But, the "help" is so teeny, I can't notice it. But, that could just be me. Will I buy it again? Most likely not. It's too expensive in my mind for what it does. That money would be better spent on another pack of creatine.

There are more pros than cons with this product, I am and will be a repeat buyer. I have tried several other fat burners from CTD, PS Sports, Cellucor, and others but I prefer this one. Pros - Only have to take one pill per day!! No crash or gitters or tingles. No rushing to the bathroom. Noticeable effects after only a week and more noticeable with future use. Cons - Not the bet fat burner to take prior to working out for energy, without having to stack it.

I was skeptical about using this, but the results I've seen definitely back up the product. I'd recommend this to anyone, and using the pre, aminos, and post workout that BPI Sports offers compliment this product nicely.

I bought two sample bottles and 3 capsules into the first bottle i knew this was a product that needed to be added to my supplement list. you will definitely feel the focus with some surges of heat that let you know the product is doing it's job. the sweat factor during workouts is awesome. you can almost hear the calories crying as they burn away. awesome product. BPI, as usual, did not disappoint.

OMGEEEE!!! You dorks!!! You are not breaking out into hives! You are all not having allergic reaction to this product! It's the niacin that cause that feeling! Niacin causes your body to get a flush. Makes your skin hurt almost like a sunburn or a bunch of needles all over your skin. It doesn't mean you are allergic it just means it's working! ANYWAYS!! This is a good product, it is kinda strong! All you have to do is open the capsule and remove some of the powder to not get the entire affect!

I took my first pill today...no any side effects beside the heart beat( not a real problem to me , i was a pro athletes , i do cardio a lot...) I thought it will give me some more power but it didn't , it even lower my muscle strength a bit..... However it did make more blood rush into the muscle which makes me not as sore as before during the workout and the caffeine help a little bit at the last 20min of my workout. I will recommend the kind of guy who is lack of willpower to take it , you will be able to do more reps. And about losing weight , i take only one pill , don't know how it works.
