    • It does its job!
Flavor Name: Watermelon Size: 9.5 Ounce (Pack of 1)
Love this pre workout. It gives me enough energy to do my cardio and training every single day. The taste is also good, not bad at all. It does have amino acids, which is great if you workout very early in the morning while fasting.

    • First Single Serving, Good Little Energy Boost, Good Taste, Good Presentation *UPDATE
Flavor Name: Watermelon Size: 1.29 Pound (Pack of 1)
So, for right now, I'm going to leave a 4-star review, only because I've just received it, and I haven't had a chance to use it for the reason I bought it for, which is to replace sugar-free Monster energy drinks that I would buy everyday before clocking in at work. I'm testing out a single serving of it now, and will update at the end of this upcoming work week. I'll leave a few initial thoughts, for now: 1. I like the presentation of the bottle; clean and precise, informative. 2. The powder, itself, is very fine and dense. I had to give it a little shake to loosen it up a bit. Reaching in to pull the scoop out left a couple finger tips covered in the super fine powder. Not a big deal, just don't spill it on accident. 3. Because of it's density it takes a short bit to get it all dissolved and mixed in, maybe 20 seconds for a couple scoops. The taste is a mild, refreshing flavor. It's not too tart, not too watered down, and easy to swig down. I'm not noticing an overpowering artificial flavor, it's pretty nice, and it doesn't give much of an aftertaste. EDIT: For this particular flavor, there is a very funky aftertaste; almost like morning mouth, or something, lol. 4. I'm getting a bit of an energy pep that isn't making me jittery, or ramping up my heart rate, but I've only taken a single serving of it (100 mg). It's probably good for a small pick-me-up, here and there. EDIT: Energy boost was good. It took my body a while to adjust to using it, after using popular energy drinks. I usually took about 150mg per serving, which is about one can of Monster, and the energy felt a bit cleaner, healthier. It's okay. So far, it's not bad. As I stated, I'll make an update after a week of using more of it before and during work. EDIT 01: I'm going to stick with the 4-star review, for now, and try out the Blue Raspberry flavor. I certainly saved more money, per day, as compared to what I'd spend on other energy drinks. EDIT 02: Blue Raspberry was good. Same points as before, but, for me, there is much less of a nasty aftertaste. I'd recommend this flavor before the Watermelon, absolutely. Pleased with Blue Raspberry; I'll buy it again :) ... show more

    • Optimum Nutrition Amino Energy – Watermelon Flavor – A Perfect Boost!
Flavor Name: Watermelon Size: 9.5 Ounce (Pack of 1)
I’ve been using Optimum Nutrition Amino Energy as my go-to pre-workout for a few weeks now, and I’m really impressed! Here’s why: Amazing Taste: The Watermelon flavor is absolutely delicious! I’ve tried a lot of pre-workouts in the past, and this one stands out in terms of taste. It’s refreshing and fruity without being too sweet or overpowering. Definitely a treat to look forward to before my workouts. Energy Boost: This pre-workout gives me a clean and sustained energy boost thanks to the Green Tea and Green Coffee Extract. I feel energized without the jittery crash that some other products give me. It’s perfect for both early morning workouts and mid-day training sessions when I need that extra kick. Supports My Keto Lifestyle: As someone who follows a keto-friendly diet, I appreciate that this product fits into my routine without any guilt. It helps me power through my workouts without kicking me out of ketosis, which is a huge bonus. BCAAs & Amino Acids: The addition of BCAAs and Amino Acids is a major plus. I feel like I’m getting that extra support for muscle recovery, which has been helping me push harder in my workouts while reducing muscle soreness afterward. Convenient and Effective: With 30 servings in the container, it’s great value for the price. Plus, I love that it mixes easily with water—no clumps or weird texture, just smooth, refreshing flavor every time. ... show more
