Here's a possible review: I'm absolutely loving Big Muscle Karnage Pre-Workout! It gives me an instant energy boost that lasts throughout my workout. The watermelon lime flavor is refreshing and mixes well with water. I experience an intense muscle pump with Karnage, making my workouts more effective. I feel the effects of Karnage within 20-25 minutes of consumption. Unlike other pre-workouts, Karnage doesn't give me any jittery feelings or crashes. I'm impressed with the quality and quantity of Karnage Pre-Workout. Bigmuscles Nutrition is a trusted brand, and Karnage is one of their best products.

I purchased BigMuscles Karnage Black expecting a reliable pre-workout supplement, but my experience was utterly disappointing due to the product’s ineffectiveness and the company’s frustratingly poor customer service. Upon receiving the product on May 30, 2025, I noticed it lacked both the Trust Seal Sticker and LV Code, raising immediate concerns about its authenticity. I contacted BigMuscles Nutrition via WhatsApp, sharing multiple images and a video of the product as requested. Their response was dismissive, claiming the batch number confirmed it as "original" and that a sticker was "missed due to high demand." However, when I used the product, it was noticeably ineffective compared to previous batches I had used successfully. After a few days, I experienced no noticeable effects, unlike the consistent performance of earlier purchases. When I raised this concern, they vaguely attributed it to "changes in raw material" and directed me to email their support team without offering a solution or replacement. I emailed [email protected] on June 2, 2025, to request a resolution, attaching images of previous batches for comparison. Over the next week, I received only responses promising a reply "by the end of the day" (on June 9 and June 11), but no meaningful action was taken. Even after 72 hours, as promised, there was no update or resolution. My follow-up emails, expressing frustration and offering additional details to expedite the process, were met with the same generic responses. By June 11, I made it clear that I was prepared to escalate the issue to Amazon and write a negative review due to their unwillingness to address the problem, yet no further assistance was provided. This experience with BigMuscles Karnage Black has been incredibly frustrating. The absence of verification stickers, combined with the product’s complete lack of effectiveness and the company’s unresponsive and dismissive support, makes me question its quality and reliability. I strongly advise potential buyers to avoid this product and choose brands that prioritize consistent quality and genuine customer care.

Bigmuscles Nutrition Karnage Black Preworkout is hands down one of the most powerful and effective pre-workouts I’ve tried. The “Sex On The Beach” flavor is refreshing, delicious, and not overly sweet, making it easy to sip before training. Within minutes, it delivers a strong energy boost, sharp focus, and incredible endurance that pushes me through even the toughest workouts. The pump is intense, strength levels feel elevated, and there’s no crash afterwards, which is a big plus. The formula feels clean and well-balanced, showing real results in performance and stamina. If you’re serious about training and want something that truly fuels your sessions, this pre-workout is a game-changer. Highly recommended for athletes and fitness enthusiasts!

Five stars from me. This pre workout shows up when you need it. Energy kicks in strong and stays steady all session with zero crash or jitters. Focus sharp as a blade and muscle pumps feel insane yet smooth no annoying itch. Flavor is refreshing and mixes effortlessly so drinking it is easy. The label is transparent about what it contains and quality feels top notch. If you are serious about training you will get your money’s worth.

Best for advance training

This pre-workout has totally improved my workouts! It offers me a steady energy boost without making me unsteady or worried. The focus is fantastic; I feel more motivated and in control with each session. It's been extremely helpful in increasing my endurance, whether I'm lifting weights or performing high-intensity exercise. The beta-alanine tingle is present but faint, which I appreciate because it makes me feel prepared to go. The flavours are delicious (not very sweet) and combine smoothly with no clumps. I also appreciate that it is made with clean ingredients, so I know I'm nourishing my body with quality. It's excellent for any lady who wants to push harder, stay focused, and feel more confident during her workouts!

DON’T BUY I received a white powder which is completely ineffective and shows no pre-workout effect at all. I have used Karnage pre-workout multiple times earlier and it always worked very well, giving a noticeable pump. That is exactly why I skipped MuscleBlaze and trusted this product again. Unfortunately, this pack feels totally different and does not work even like a normal pre-workout. It seems either defective or of compromised quality. I have wasted ₹1500 on this product.
