Product description

Product Description

Reflex Nutrition The Muscle Bomb Energy Pre Workout is scientifically formulated to elevate your training sessions with unmatched power and focus. Whether you are hitting the gym for strength training or endurance workouts, this lit pre workout powder is designed to stimulate, pump, and sharpen your mind, preparing you for peak performance. Packed with a potent 350mg of caffeine (high stim pre workout variant), The Muscle Bomb pre workout supplements give you an intense pre workout pump, combating fatigue and helping you power through the most challenging workouts. The caffeine-free variant of this dope pre workout provides the same explosive benefits, minus the caffeine, ideal for evening sessions or those sensitive to stimulants. At the heart of The Muscle Bomb preworkout shots is 9g of Citrulline Malate (6g active Citrulline). This powerful ingredient supports nitric oxide production, enhancing blood flow and delivering muscle pumps that not only look great but also aid in nutrient delivery and endurance. To ensure you push your limits, 2.5g of Beta-Alanine is included, helping to buffer lactic acid build-up, delaying muscle fatigue so you can squeeze out those extra reps. Combined with L-Tyrosine and L-Taurine, this anabolic pre workout contains essential Amino Acids, building blocks of protein. Hydration is key during intense workouts, which is why The Muscle Bomb pre workout supplement without Creatine also features a blend of essential electrolytes. These help maintain fluid balance, ensuring you stay hydrated and perform at your best. Available in bold flavours, The Muscle Bomb pre workout advanced offers a smooth, clump-free mix, making it a convenient and delicious part of your routine. Whether you prefer the high-energy caffeine variant or the more relaxed caffeine-free option, Reflex Nutrition has crafted a pre-workout powder that delivers on every front: energy, pump, focus, and taste (preworkout men, pre workout women).

Powder is stuck together
Gutted as it has came and its completely solid when opened so not sure the quality is going to be there and going to be annoying to grind it down into powder to get an actual scoop

    FINALLY i have found a pre workout that tastes nice!!
    It tastes like good ol lemon squash not as zingie more sweet but i like it and its certainly better than many i have tried.
    You know exactly what to expect with the flavour. No creative names or monkeys or dragons just lemon. Thank you.

    The previous version of this was great.
    Then Reflex decided to discontinue it and make this version which is terrible. No pump, no tingle, and always turns up clumped together and solid! It does NOTHING for me. I always used Reflex for all my supplements but they just lost a long time customer. Never buying this again, it’s garbage and a waste of money!!

    Flavour Name: Sherbet Lemon - Caffeine FreeVerified Purchase
    Great pump product without the caffeine so helps fuel the nighttime work outs perfectly. It does make me extremely tingly but it has been dosed well. Flavour is tolerable but would prefer alternative flavours without caffeine in the future.

    Flavour Name: Twizzle LollyAmazon Vine Customer Review of Free Product( What's this? )
    This is definitely one of my favourite pre workouts i've tried in quite a while.
    Not only did the twizzle lolly flavour taste absolutely amazing but i've had a really good boost for my training sessions every time i've used it so far.

    Depending how you use this pre workout you can either single scoop for 175mg of caffeine or double scoop for the full 350mg, however double scooping with drop the number of servings in the tub down to just 20 servings verses 40 if you single scoop.

    Where i normally train at night after i finish work i've only really been using a single scoop serving because i don't want too much caffeine late at night but even with the 175mg servings i have still been having really nice boosts off of it to fuel me through my training sessions.

    I found it mixes into the water perfectly every single time & is ready to drink within a couple of seconds.
    But the best bit by far for me is the flavour, if you have a sweet tooth & like sweets but are trying to keep to your meal plan this truly is a treat as it tastes so good.
    But it is nice to get to have a unique flavour that's not the exact same as every other pre workout out there that we've all had a million times over already.

    Only thing i would say & its down to personal preference but i did tend to use a little more water than the recommended 200ml of water per scoop.
    I just felt at 200ml it was a little too strong for my liking but at around 300ml i found it a really enjoyable to flavour to drink before my workouts.

    Definitely something i will be getting again in the future although i'm now intrigued to try any other unique flavours they may have.

    Can't use it as it's in one lump stuck together.
    This is however a good pre workout. Used it tonnes of times before but this tub is damp inside.

    Flavour Name: Twizzle LollyVerified Purchase
    I spent a hile looking for a cheap pre workout without creatine, and decided to give this a shot.
    I don't know if it's a poor product or Amazon's storage, but my tub was solid... After a few minutes with a fork, and squeezing the sides of the tub, I was able to get myself a scoop.
    It dissolves well, tastes alright, and seems to work. I have one scoop before the workout, the another during, and I've had no issues with side effects yet. Whether there's more energy than other pre workouts, I can't say, but I definitely prefer zero creatine.
    I'll try it again, assuming I got a bad tub. Assuming it's alright, it's good value for money.

    Flavour Name: Twizzle LollyAmazon Vine Customer Review of Free Product( What's this? )
    This is a powdered drink mix with an appreciable amount of caffeine, which seems to give a boost quicker than the equivalent amount of coffee or similar. The flavouring (I ordered the twizzle lolly flavour) is certainly potent, although to be honest it isn't entirely pleasant: starting off nice enough if quite overpowering at the recommended concentration, it comes across as quite artificial-seeming, with a slightly bitter aftertaste that further dilution doesn't seem to do much about. There usually seems to be a little residue left undissolved at the bottom of the glass as well even after some thorough mixing, but perhaps I just need to mix harder. To be honest, any issues with the taste aside it certainly delivers in the boost department and seems to make exercise rather easier, so can't complain about the effect. That said, it is rather pricey, so only worth ordering if you know you're going to use it; the powder inside the tub starts to clump together after a while (at least in the atmosphere around here), so it might be worth transferring to a properly airtight container for long-term storage.
