Muscle Bomb Pre Workout Review

Muscle Bomb is a new high-end pre workout made by Reflex Nutrition and manufactured exclusively in the United Kingdom. This new pre workout is available in both caffeinated and non-caffeinated forms and we had the privilege of trying them both. Overall, our experience with Muscle Bomb was great and we highly recommend it to our fellow bodybuilders in the UK. Here is our experience with and overview of Muscle Bomb.

The best UK pre workout supplement we’ve tried

Muscle BombWhat makes muscle bomb special? It’s not flashy advertisements, a bright colored container, super concentrated claims, or even a mega-death dose of stimulants… Muscle Bomb contains none of that. What makes muscle bomb special is the fact that it’s based on scientific dosages; aka the doses shown to produce results (but too expensive for most companies to use).

You know it’s actually pretty crazy how effective this pre workout is, considering it isn’t geared to super-stimulate your central nervous system with synephrines, pikatropins, yohimbes, and etc. In fact, it’s important to point out that your first few workouts with a supplement like muscle bomb, you may find yourself a bit confused. That’s because Muscle Bomb derives extra power from your actual muscle tissue, and not the CNS. This produces a much more functional and natural workout experience that is much more beneficial for muscle growth than the stimulant loading you find in most ‘concentrated’ pre workouts.

What’s in Muscle Bomb

Like we said before, the ingredients in muscle bomb is what makes it important. When you take muscle bomb, you can either take one or two scoops. With one scoop, you are getting a 15 gram serving size containing a complete 4 grams of L-Citrulline, 1.7 grams of leucine, 1.6 grams of beta-alanine, 1.4 grams of betaine, 9 grams of protein, and if you are taking the caffeinated version – 125 milligrams of caffeine, and a few more ingredients. If you don’t read the back of your supplement labels often, this may not seem like a big deal. But, to put things into perspective – some pre workouts are only 4 grams total; in muscle bomb, one ingredient totals 4 grams in this 15 gram scoop!

Muscle Bomb UK Pre Workout

Working out with Muscle Bomb PWO

Working out with muscle bomb is intense! Not antsy or drugged out intense; but rather focused and powerful – a silent confidence. When I first took Muscle Bomb, the first thing I noticed was the beta-alanine presence rushing through my veins (a good indicator of ingredient quality). Next, as I began lifting – my pump was off the chain. During my entire workout, I was able to push myself hard; harder than normal. The only limiting factor was whether or not I remained properly hydrated (drinking 1-1.5 L water per workout).

Something about the intense large dose Citrulline pump, heavy BCAA presence, and the just right stimulant push from 125 grams of caffeine really put me in the zone. The only thing better than this was taking 2 scoops of Muscle Bomb which took it to a whole new level.

Muscle Bomb Experience

Overall, this was a great pre workout and it’s exactly the type of pre workout I feel comfortable putting into my body. It’s literally built for building muscle, has caffeine but not enough to mess you up, and in my personal opinion is a healthy long-term option. If I was in the UK, I would be taking nothing but this pre workout.

Quick Notes –

  • The caffeine levels were just right for a good stimulant push.
  • The Combination of BCAAs, Citrulline, and Beta Alanine made my workouts last longer and promoted serious muscle pump.
  • The high Leucine content makes this a true muscle builder.
  • Taking 2 scoops is killer, in a good way.
  • The Caffeine free version is awesome for late night lifts and works very well. I would definitely use it during no-stimulant months in confidence.
  • This pre workout is a little pricey, but it is one of the best muscle building pre workouts out there.
  • We would rank this pre workout high on our supplement rankings, but our following is primarily USA based.
  • If you’re in the UK or European Union, has muscle bomb for cheap. Otherwise, go to and email Mark about placing your order; he’ll take care of you!
