A friend from uni started using this product and raved about it constantly so I decided to give it a try. The positives do outweigh the negatives but nevertheless, there are negatives to the product. The downsides include: it does help with your workout but increases the amount you sweat enormously (which can be embarrassing in the gym), the taste is pretty awful (i've tried 3 flavours and not ones been nice), the effects where off very quickly when doing cardio as opposed to weight training after using the product 3 times i upped the dose, as reccomended and felt barely any extra energy on my 4th workout (however, aftr a weekend off and going back to the product on monday, it did rekindle the effects) and whilst it gives you a high focus and energy release in the gym, you do feel more deflated after (obviously youre doing more work but it shouldnt drain all your energy after).
The positives of this product though, are what should be focused on and what should convince you to buy the product. I only stated the negatives first as they're minor compared to the positives. They include: the fact that your metabolism rockets through the roof creating a lot of fat loss and more protein synthesis in your muscles, youre focused and determined at the gym and heavy weights do seem lighter, as opposed to other high caffeine products, this doesnt keep you up all night, (i find) it makes the gym more enjoyable as you break barriers and previous personal records, you only need to take little scoops out of a moderately big tub meaning it lasts for ages, the price is amazing for what it does and finally, there are no bad side effects (i.e, illness or using the bathroom more often).
All in all, it is a good product, not an amazing product as the cons do need to be addressed, I dont want to be going for an early morning workout and find myself exhausted for the remainder of the day. But if you are serious about gaining muscle, boosting your metabolism and getting a lot more from your workouts - BUY THIS PRODUCT!!!
