Echo Supplements on Reflex Muscle Bomb

Muscle Bomb is Reflex Nutrition's latest pre-workout supplement and the formula really appeals to us at Echo. There isn't a huge ingredient list which means that the ingredients Reflex have included are in really... really high doses!  

Reflex have covered a few bases with Muscle Bomb - recovery (from iBCAAs) to muscle pump (Citrulline Malate) to energy and endurance from Beta-Alanine, Betaine and L-Carnitine Tartrate. Most pre workouts that attempt this approach fail due to low dosages but that definitely isn't the case with Muscle Bomb. With 7g of instantised branched chain amino acids (iBCAAs) you will get a higher dose in a single serving of Muscle Bomb than most stand-alone BCAA supplements.

Similarly we have never seen a dose of Citrulline Malate as high as 8g - and we're serious about that, most pre-workout supplements have a dose of around 3-4g at best. Beta Alanine is dosed highly enough that at 2 scoops you get a full days worth (3.2g) of this super supplement; again this could easily replace a standalone beta alanine supplement!

Reflex Muscle Bomb Key Facts

Muscle Bomb comes in 2 different varieties - with and without caffeine - which means you can choose to take advantage of the performance boosting ingredients without having a high caffeine dose if you prefer, or you can take the non-caffeine version on rest days, as the ingredients will be beneficial if taken daily. This product is the caffeinated version which has 250mg caffeine per 2-scoop serving.

Reflex Muscle Bomb - Manufacturer's Description

What do you expect from your pre-workout in terms of results? If you want more, if you want those around you to recognise those differences, then you have to optimise every part of your approach.

Categorically and factually one of the world's most, if not the most, potent pre-workout formulae available delivering mega doses for all main ingredients in line with double blind scientific studies. Muscle Bomb is also free from artificial colours and sweeteners.

Key Ingredients:

  • iBCAA 7,000mg
  • Citruline malate 8,000mg
  • Beta-alanine 3,200mg
  • L-Carnitine tartrate 2,000mg
  • Betaine 2,500mg

The problem with most pre-workout products
The market is now flooded with pre workout products and it’s nigh impossible for the consumer to be able to make an informed choice between products with scientifically proven dosages on all key ingredients. Most pre workout products are made from proprietary blends which do not tell you the amount of each active ingredient.

The other significant issue is that nearly all pre-workout products are loaded with caffeine which can disguise a very poor formulation. Caffeine on its own is a powerful ergogenic aid and it’s inexpensive, so it’s normally at the top of the list for most supplement companies to use.

Muscle Bomb, it’s a logical formula supported by science
Muscle Bomb contains fifteen ingredients, seven of which are specifically chosen for their role in the best pre-workout performance, available with and without caffeine. All doses used are at the minimum level used in double blind scientific studies. We’d strongly encourage you to look them up or follow the links on our Muscle Bomb website page. Each of the studies relating to each of the seven key ingredients are also listed below so that you can see first-hand that the doses used in real studies match those found in Muscle Bomb. Be in absolutely no doubt that this has a profound difference to a pre workout formula. Once you try Muscle Bomb we are convinced that you’ll never use another product.

Here’s the kicker that really puts Muscle Bomb into a league of its own, its contains a truly HUGE 25,400mg of active ingredients per 2 scoops (30g):

Key ingredients No.1, 2 & 3 – iBCAA 7,000mg
The 3 branched chain amino acids, L-leucine, isoleucine and valine, all micronized and instant mixing, in the most proven 2:1:1 ratio, they are arguably the most important amino acids an athlete can take. Each double serving contains 7,000mg which is more than the dosage used in a double blind scientific study that demonstrates the anabolic activity of BCAAs during exercise.

The study you need to read: Intake of branched-chain amino acids influences the levels of MAFbx mRNA and MuRF-1 total protein in resting and exercising human muscle. Dose used in study 6.8g for an 80kg athlete.

Key ingredient No.4 – Citrulline Malate 8,000mg
Citrulline malate is one of the best pre-workout supplements for great pumps, delaying fatigue and pushing more reps. Our citrulline malate is in a 2:1 ratio of the amino acid citrulline and malic acid. Although highly popular many supplements only contain a couple of grams at best, science says much more is needed; in fact you need 400%-800% more than most products provide. Muscle Bomb delivers that dose, its 8,000mg per double serving.

The study you need to read: J Strength Cond Res. 2010. Citrulline malate enhances athletic anaerobic performance and relieves muscle soreness. Dose used in study 8,000mg.

Key Ingredient No.5 – Beta-Alanine 3,200mg
Increase muscle carnosine levels with beta-alanine, increase endurance and stamina with proven doses. Scientific studies prove that 3,200mg per day significantly increases carnosine levels in muscle.

The studies you need to read: Amino Acids. 2012 Effect of two β-alanine dosing protocols on muscle carnosine synthesis and washout. Dosage used 3,200mg. Role of beta-alanine supplementation on muscle carnosine and exercise performance.

Key ingredient No.6 – L-Carnitine Tartrate 2,000mg
Another great addition to any pre-workout regime. Carnitine is used by the body to effectively use fat for energy. However scientific studies show it has other significant actions for the athlete, a mega dose of L-carnitine tartrate restores muscles after training and increases the number of testosterone receptors in muscle.

The study you need to read: Metabolism. 2010. L-carnitine l-tartrate supplementation favourably affects biochemical markers of recovery from physical exertion in middle-aged men and women. Dosage used 2,000mg.

Key Ingredient No.7 – Betaine (trimethylglycine) 2,500mg
Another one of the best sports nutrition supplements that has recently become the focus of more scientific studies because of its ability to build lean mass. It shouldn’t come as surprise by now to hear that the double dosages used are significant, often up to 500% more than the doses often found in other pre-workout products. Muscle Bomb once again delivers by supplying 2,500mg, the very same daily dose used in the study listed below. That’s why you will find a mega dose of betaine anhydrous 2,500mg.

The study you need to read: J Int Soc Sports Nutr. 2013 Aug. Effects of betaine on body composition, performance, and homocysteine thiolactone.

Additional ingredients: Muscle Bomb pre-workout contains additional ingredients including caffeine (caffeine version only), taurine, sodium bicarbonate, VpNOS (grapeseed and pinebark extracts), vitamin B6, folic acid and vitamin B12. All of these ingredients are added to round the product off making Muscle Bomb the complete pre-workout product that you expect from Reflex Nutrition.
