C4 Sport®, Pre-Workout, Blue Raspberry, 7.5 oz (213 g)

The quality is fine and the taste (blue raspberry) is actually decent, but overall this pre-workout feels very soft. It doesn’t give enough kick or stamina for HIIT or hard workouts, and the efficiency just isn’t there compared to other stronger formulas. On the plus side, it’s cheap and might be okay for beginners or for lighter training sessions. But if you’re looking for real intensity and performance, this one falls short.

I've been using it from iHerb for a few weeks now, and I'm genuinely satisfied with both the product and the service. The item arrived well-packaged and on time, which is typical of my experience with iHerb orders. As for the product itself, it lives up to its claims. The quality feels consistent, and the ingredients seem clean and reliable. I appreciate that iHerb provides detailed product descriptions, customer reviews, and supplement facts—helpful when comparing options. The pricing is also fair, especially with the occasional discounts and rewards program. Overall, I'm happy with my purchase and plan to reorder. iHerb continues to be a trustworthy platform for wellness and supplement needs.

Snagged the rose water toner during a flash sale and it’s shockingly good. The scent reminds me of actual garden roses, not perfume. It calms the redness around my nose instantly. I decant it into a small spray bottle for midday refreshment.

I am using this from last 10 days It's really work on me. I took 45 minutes before my workiut session it's gives really strength. And the quality is really good what i need and i took blue raspberry the taste is also awesome.

Thank you very much for this product, it suited me, I like the packaging, comfortable and stylish, I will order more of these products, and recommend them to all my friends and relatives! good!!

Wow that was so good 😊 and the first thing you do to get

This pre-workout is very effective and gives a clean energy boost without feeling too heavy. It helps improve focus, endurance, and overall workout performance. The blue raspberry flavor is refreshing and not overly sweet, making it easy to drink before training. It mixes well and works consistently every time. Great quality product and definitely worth repurchasing.

Great product! The quality is excellent and it works exactly as described. I noticed positive results after using it consistently, and the ingredients seem clean and effective. The packaging was perfect and the product arrived in great condition. I would definitely repurchase and recommend it to anyone looking for a reliable product.

I ordered this one based on quality ingredients, as others have more harmful additives like green tea extract and cassia cinnamon. This brand has been around for 15+ years to my memory and I trust them. Anyways, gives energy and focus to run longer and faster and also to focus better at work:

I recently started using C4 Sport pre-workout, and I’m impressed with its quality and performance. The ingredients are well-formulated, and each serving size delivers an effective dose to support energy and focus during training. The composition works perfectly alongside my diet and protein intake, providing a noticeable boost to muscle endurance and overall workout performance. The benefits are immediate — increased energy, improved focus, and enhanced stamina throughout my sessions. The package is vibrant and practical, making it easy to store and carry. The taste is excellent, with a refreshing flavor that makes it enjoyable to mix with water before workouts. Overall, C4 Sport combines high-quality ingredients, well-balanced composition, and real benefits for energy, muscle performance, and training results.
