Product Overview



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

55g of protein

The main protein source in One Stop® Xtreme is an EU sourced grass-fed dairy protein blend. It contains 55g of protein derived 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.

5g of Creapure® creatine

The next ingredient is 5,000mg of Creapure® creatine, it’s the world’s most researched form of creatine. It is a proven creatine with a patented manufacturing process that has unbeaten levels of purity, is highly effective and above all, guaranteed to be safe.

packed with amino acids

No serious all-in-one bodybuilding supplement would be complete without the following highly popular and highly acclaimed amino acids; 3,000mg of pure free form L-leucine, 1,800mg of beta alanine, 2,600mg of betaine anhydrous and 1,500mg of L-taurine.

zinc bisglycinate

Next is the 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 supporting cognitive function.

magnesium bisglycinate

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.

friendly bacteria

Three different strains of friendly bacteria 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.

Verified Buyer

I love this product!! In the past 3 months that I have changed to this product I have seen my body size grow - biceps, shoulders, chest, thighs and calves - quite dramatically. Upper body parts by about 1/2" every couple of weeks, lower body by 1/4" every month.... My bench pressing has gone from just over bodyweight to almost 1.5 x bodyweight..... Flavours are good and with a recycle-able bag instead of a big tub it's environmentally sound too.... Lots of additional ingredients including your protein and creatine so you get all your vitamins and minerals to aid good growth..... From stunted growth with my other protein supplement over the course of the last year to the gains that I've had recently..... Very impressed!! I'll pin my dedication to this product..... All flavours taste great.... Geoff x
