It is fair to say that Reflex Nutrition probably has more experience making all in one bodybuilding supplements than any other UK company in the industry today. In 1997 we launched our first ever product, called Advantage, which was an all in one bodybuilding supplement that contained Whey Protein, Creatine, Glutamine and essential vitamins.

Today, getting close to 20 years later, we have two specific products that are designed solely as all in one bodybuilding supplements. They are the original One Stop, which is designed for anyone wanting one product that delivers results and covers the essentials.

The second product is called One Stop Xtreme, detailed bellow, which takes everything we know about bodybuilding supplements into account. It literally contains just about every single super high quality bodybuilding supplement that’s worthwhile all in one product.

One Stop from Reflex Nutrition delivers on a very serious level, it’s a unique formula which has been very carefully designed with a sole aim, to deliver the best of the best, to outperform and provide superior quality from each and every ingredient.

Because One Stop has been formulated to replace the use of numerous supplements we did not want to fall into the trap of making compromises. For example the use of cheaper forms of creatine, vitamins, minerals and perhaps more importantly the protein source.

Instead One Stop is a complete powerhouse of the world’s finest sports supplements in one easy to use shake;

With Exclusive high B.V Quattro® Protein Blend

The protein source found in One Stop, like nearly all our proteins, is an exclusive EU sourced grass fed dairy protein blend as the primary protein source. Our exclusive high B.V Quattro® protein blend is made from Whey Protein Concentrate, Native Whey Protein Isolate, High DH Whey Hydrolysate and Micellar Casein, all EU sourced, all from grass fed milk. We’d argue that it’s one of the finest blends you will ever find in an all one muscle builder. It provides a very rich source of Branch Chain Amino acids, Essential Amino acids and Glutamine. We’re also keen to stress that One Stop Xtreme does not contain any added lower quality Soy Protein which contains Trypsin inhibitors which may actually prevent protein digestion.

Low GI Carbohydrates

One Stop’s main carbohydrate source is a high quality EU sourced combination of low GI oats and barley. Both oats and barley are superb sources of complex carbohydrates and dietary fibre, not mention naturally occurring vitamins, minerals and fatty acids. Other products may just use dextrose (sugar) as the carb source, not what we would term healthy.

The World’s No.1 Creatine, Creapure

We now move onto one of the One Stop’s primary bodybuilding supplements. Creapure Creatine, it’s the world’s most researched form of creatine with studies relating to its role in many different forms of exercise and safety. A glass of fresh water can contain harmful bacteria and germs but to the naked eye it looks just as good as 100% pure water. This is true for creatine too. Even though creatine can look like pure white powder, it can be of inferior quality, containing toxicologically harmful impurities. It’s therefore vital that you choose a proven creatine that is both extremely pure, proven to be highly effective and above all proven to be safe; it’s for this very reason that Reflex Nutrition only supply and manufacture products with Creapure® creatine monohydrate.

Supporting Healthy Testosterone Levels, Normal Protein Synthesis and Muscle Function and your COMPLETE A-Z !

Many all in one bodybuilding supplements contain minerals, few if any supply the type of minerals that One Stop Xtreme does, we feel that’s something that should be done right or not at all;

Certain minerals are very important to athletes and hard training individuals especially compared to the average person. Two minerals in particular that really can make a difference are Zinc and Magnesium both of which are found in One Stop Xtreme supplying at least 100% of the Recommended Daily Amount per daily serving;

The zinc used in One Stop Xtreme is a highly bioavailable form called Zinc Monomethionine which contributes to the maintenance of normal testosterone levels in the blood, normal function of the immune system, normal carbohydrate and metabolism and protein synthesis, protection of cells from oxidative stress as well as normal cognitive function. We do not use the inferior cheaper form Zinc Oxide.

The magnesium in One Stop Xtreme is also contained in a highly bioavailable format called Magnesium Citrate which contributes to normal muscle function, normal energy-yielding metabolism, a reduction of tiredness and fatigue and normal functioning of the nervous system. Once again we do not use the inferior cheaper form Magnesium Oxide.

To complete the picture One Stop Xtreme provide 100% of the RDA of all your daily vitamins, in addition we’re sure you will also welcome the inclusion of friendly bacteria and Digezyme enzymes.

Great Flavours that mix perfectly in a shaker

Using our new flavour technology we are continuously making improvements to the flavours of One Stop Xtreme. Its not an easy task when you consider the vast array of ingredients in this amazing product. It mixes perfectly in a shaker without clumps in just a few seconds and coupled with the great flavours makes using One Stop XTREME very straightforward.

Additional Product Information

Each serving of One Stop XTREME contains 3,000mg of L-leucine.

Because one stop XTREME contains such a potent complex of whey peptides and whey fractions it contains naturally high levels of branched-chain amino acids. Just one serving provides 10,500mg of BCAA’s (Branched chain amino acids).

It contains 5,000mg of Creatine© creatine monohydrate which is unbeaten in terms of quality and safety. Nearly all of the scientific studies relating to increased muscular strength, increased power, increased endurance and increased lean body mass have one thing in common. They all used Creapure creatine monohydrate. That is because Creapure© is recognised as the best quality creatine monohydrate available today.

The harder, more intensely you train, the greater performance and results. However, with intense training comes lactic acid, ammonia and acidity build up. Industry leading doses of 1,800mg beta-alanine are found in just 1 serving of One Stop XTREME.

Each serving contains 10g of glutamine peptide which are absorbed by the body more easily than normal L-glutamine. This is especially important in an all-in-one formula where protein and other amino acids will compete for absorption.

By including 100% of the RDA of vitamins in the daily serving, One Stop XTREME is unique in the all-in-one market.

One top XTREME contains zinc monomethionine, the highest known quality form of zinc. This is instead of the cheaper, less easily absorbed zinc oxide. Avena sativa is included as is magnesium, in the high quality form of magnesium citrate (instead of magnesium oxide) which contributes to normal protein synthesis, normal muscle function and a reduction of tiredness and fatigue.

Finally, LactoSpore probiotics are added for gut health and Digezyme digestive enzyme complex is added along with BioPerine.
