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 produc

Final Word

Muscle Bomb® pre-workout is one of a kind. Enjoy the great range of fruit flavours, free from artificial colours it also happens to be one of the only pre-workout products that’s completely free from artificial sweeteners.
We categorically guarantee that Muscle Bomb® will blow you away, if it doesn’t simply return it for a full refund.
Quoted dosages are for double servings.

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.
