Overview of Sinister Labs SINFIT Bars

Sinister Labs, makers of the epic protein and caffeine infused nut butter spreads, has the mastermind of Scott James behind it, along with Mr. 212 Flex Lewis. Sinister Labs is aiming to make better tasting food products that help contribute to your gains.

The SINFIT Bars from Sinister Labs are game changing in terms of texture and taste. Soft, chewy and delicious, these bars can be addicting. The one area in which you might want to draw some concern is to the macros since it is a bigger, carb packed bar. If you are not concerned as much with calories and carbs and you just want the best tasting and textured bar out there, then Sinister Labs SINFIT Bars are exactly that.

Why You Should Trust Our Reviews

    Our review panel is made up of individuals with many years of experience in the sports nutrition industry, dating back to the early 2000’s. Their tenure gives them knowledge on brands, supplements, ingredients, dosages and more.
    Unlike the majority of “review” sites on the internet, Fitness Informant reviews every supplement on a full-container basis. What does this mean? It means that a review is not written or recorded until the last serving of that product has been finished. We’ve all had products that were great for the first couple of days, but then lost their effectiveness shortly after. We want to ensure you are getting a full review based on a full product.
    We breakdown each ingredient in our reviews to educate you on exactly what the ingredients do, and what is the proper dosage of each ingredient to effectively do what they are intended to do.
    Our number #1 priority is to inform you proper supplement selection through honest reviews. The majority of “review” sites on the internet will push you to buy a certain product based on the commissions they received. Not us. We want you to purchase the highest quality supplements at the best value. We put your health and wellness first. To achieve your goals we want you to use only the best supplements that you can afford. We do this by being honest.

Testing Results and Ratings

We reviewed Sinister Labs SINFIT bars on four categories. We first start by looking at it’s ingredient profile. This portion of the review looks at quality of protein used in the protein bars and amount, macros and other ingredients involved in the making of this protein bar.

Then we move into the taste of the different flavors we’ve tried. We grade each flavor separately and average the scores for their overall taste rating. We were able to try the following flavors: Chocolate Crunch, Peanut Butter Crunch, Cinnamon Crunch and Caramel Crunch.

Texture is important in a protein bar selection. We review the texture as well. We discuss chalkiness, chewiness, softness and crunch.

Finally, we talk about value. Value is the combination of profile, taste and texture in relation to cost. Another part of value are the competitors and other versions of protein bars available on the market.

Ingredients Profile


Prior to buying a protein bar at a convenience store, or even online, most of us tend to look at the macros. These are extremely important because we all have various fitness goals. If you’re cutting, for example, then you might want a protein bar that limits the carbs. I will say right away that the SINFIT Bars are not that. If you’re bulking, you may look for a bar that could essentially be a meal replacement bar.

SINFIT Bars from Sinister Labs are big in terms of size and macros.  Let’s start with the macros:

Calories: 350
Protein: 30
Fats: 16g
Carbohydrates:​ 28g

Yes, this bar is much bigger than most on the market (hence our conversation during the value section). These are not made for those of us trying to cut carbs. At 350 calories these bars could almost double as a meal replacement bar. I like that a lot about them.

You don’t find many bars with a protein level over 20g. This does. Th​e bar contains 30g of protein from Whey Protein Concentrate and Whey Protein Isolate (you get some from Soy Protein Isolate too). If you’re protein deficient in your diet then this would be a solid choice.

Carbs are higher than most at 28g. However, you are not finding the use of sugar alcohols here, which has a tendency of being hard on your stomach. They do use an addition of 7g of sugars, which I am not too keen on, but I realize in order to make a bar that tastes good, and since this is so big, it makes sense. If you look at a smaller size bar like Quest, they could have gotten away with using almost 50% less sugar. ​You do have 1g of Dietary Fiber which reduces the NET Carbs to 27g.

Fats, important to a lot of people, come in at 16g. They are 8g of Saturated Fats (bad fats) and 8g of Unsaturated Fats (good fats). Now, Saturated Fats should be limited in your diet. At 8g of Saturated Fats this won’t kill you or make you unhealthy. Look at a Snickers Bar, it is 1/2 the size of this bar and contains 5g of Saturated Fats and no Unsaturated Fats. Just use that to put it into perspective. Unsaturated fats are good for you. We’re lucky here that this contains 8g​ as well.

There’s nothing out of the ordinary on the ingredient list. You find a lot of these in protein bars on the market. You do find your total grams of sugars in the ingredients but then again you find your 30g of protein as well. This is a good bar, not as clean as others, but a good solid bar that will fill you up.​

Chocolate Crunch: (9/10)
Peanut Butter Crunch: (7/10)
Cinnamon Crunch: (9/10)
Caramel Crunch: (10/10)

One of the best tasting protein bars I have ever had, prior to testing these, was another baked bar from another company, ProSupps MyBar. This bar rivals that for taste. The combination of the texture along with taste makes these great. Plus, I just think baked bars without sugar alcohols taste better.

My favorite flavor of the SINFIT Bars was Caramel Crunch. If you’ve ever gotten a dipped ice cream cone with the hardshell on it, the caramel or even butterscotch, it tastes like that shell. It’s unreal. My second favorite flavor was Cinnamon Crunch, followed by Chocolate Crunch (very rich in chocolate flavor) and finally Peanut Butter Crunch. It was surprising that I like Peanut Butter Crunch the least since I love their spreads so much. The coating on these bars is top-notch.

Overall, these taste great and your taste buds will thank you!



This is the big advantage that baked protein bars have over the ones like ONE Bars and Quest Bars…the texture is softer and more chewy. These are extremely soft, which makes eating them fairly easy. You’re not getting the chalkiness that you get with some protein bars. We all hate that, don’t we? It’s almost as if you’re eating a piece of cake, covered in a nice coating.



SINFIT Bars do retail higher than other competitors in the same category, but it’s important that we do the math. Let’s take Quest Bars for example. Each bar is approximately 60g. You get 12 per box for $25. That’s 720g of bars for $25 which is $.034 per gram. Each SINFIT bar is 83g. Let’s do that same math. That comes out to be $.035 per gram. Is it really that much more? Plus, these trump the taste of Quest…by a long shot. ONE Bars are also 60g and retail for the same as Quest…so not much of an argument here.

Per gram of protein bar, these are right in-line with the competition and they are much better tasting than the vast majority of the competition. Don’t let the sticker price shock you. These are the real deal and are worth every penny.
