Reflex One Stop Xtreme 2Kg


Reflex One Stop Xtreme 2Kg Product Information

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

EU Sourced Whey Protein and Native Milk Protein, Fast & Slow Proteins.

The main protein source in ONE STOP® XTREME is an EU sourced grass-fed dairy protein blend. Made from preferentially selected undenatured ultra filtered whey protein and undenatured native milk protein providing a valuable source of micellar casein. It provides a very rich source of branched-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 that may actually prevent protein digestion.

The World’s No.1 Creatine, Creapure®

Creapure® creatine, it’s the world’s most researched form of creatine. It’s vital that you choose a proven creatine that is both extremely pure, highly effective and above all safe; it’s for this very reason that Reflex Nutrition only supply and manufacture products with Creapure® creatine monohydrate.

Additional Amino Acids

No serious all-in-one bodybuilding supplement would be complete without the following highly popular and highly acclaimed amino acids; pure free form L-Leucine; Beta Alanine; Betaine Anhyrdous and Taurine.

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

ONE STOP® XTREME contains highly bioavailable zinc bisglycinate made using a patented process by the highly acclaimed mineral specialist Albion® Minerals. Zinc contributes to the maintenance of normal testosterone levels in the blood, normal function of the immune system, normal carbohydrate metabolism and protein synthesis, protection of cells from oxidative stress as well as normal cognitive function. The magnesium bisglycinate in ONE STOP® XTREME is also made by Albion® Minerals. Magnesium contributes to normal muscle function, normal energy-yielding metabolism, a reduction of tiredness and fatigue and normal functioning of the nervous system. We do not use the inferior and cheaper form magnesium oxide. To complete the picture ONE STOP® XTREME also provides 100% of the NRV of all your daily vitamins.

Now with Patented LAB2PRO® Friendly Bacteria

Three different strains are used; Lactobacillus acidophilus, Bifidobacterium lactis and Lactobacillus rhamnosus. LAB2PRO® friendly bacteria have been coated using a patented multi component protection process to ensure that they reach the upper intestine intact. More information is available on LAB2PRO® website.

Results Money Back Guarantee

Use ONE STOP® XTREME as directed with an intense weight lifting programme and if you don’t experience the results you were expecting we’ll happily refund your purchase price in full. See website for full terms and conditions.


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.
