Product description Reflex One Stop Xtreme

One Stop XTREME - THE HARDCORE BUILDER

One Stop XTREME is the strongest hardcore version of Reflex Nutrition that has been developed in the last 15 years! The whole product concept is designed for all athletes whose goal is muscle growth. The base of One Stop XTREME is the patented Quattro® gradual release protein blend, which as ALWAYS in every production batch of the product is tested for guaranteed content of the proteins and amino acids used.

55 g of special Quattro gradual release protein blend

Probably the most sophisticated protein and amino acid blend developed to date. The base is a combination of premium whey protein, native whey protein and micellar casein. The fast-release versus gradual-release amino acid sources are in an optimized ratio of 3.35:1, exactly what is best for muscle fibers.

Only top quality: One Stop XTREME does not contain non-full-fat protein sources such as soy concentrate, collagen (protein of bovine origin), calcium caseinate, dried egg white and more.

Additive 3.000 mg mTOR L-Leucine

L-Leucine is known to be the most potent amino acid of all the essential amino acids.

10,320 mg of BCAAs in each serving

Due to the use of high BCAA protein (fermentation source), each serving of One Stop XTREME contains 10,320 mg of BCAAs within the protein used. If we add the additive mTOR L-Leucine, which is also one of the BCAA amino acids, we get an incredible total of 13.320 mg of BCAAs!

5,000 mg of patented Creapure® creatine monohydrate

Creapure® is considered the most effective creatine available on the market today.

A proven, functional dose of Beta-Alanine

A daily dose of One Stop XTREME contains 1,800 mg of beta-alanine.

Glutamine peptides

Glutamine peptides are absorbed by the body much more readily than L-Glutamine alone, which is especially important in products like One Stop XTREME where absorption is affected by other proteins and amino acids.

Full vitamin doses

With 100% RHP of all essential vitamins ( note for 2 doses per day ), One Stop XTREME is completely unique among all-in-one formulas.

Zinc Bisglycinate, Magnesium Bisglycinate and Avena Sativa Oats

Current EU legislation does not allow us to describe the benefits of this combination, but our own experience will give you a clear answer.

It contains stable probiotic cultures and digestive enzymes

Digezyme® probiotic cultures and enzyme complex aids in digestion and nutrient absorption. Another ingredient is BioPerine®, which increases the utilization of individual ergogens.

REFLEX NUTRITION will fully support you throughout your journey

If you want to make the most of the potential of One Stop XTREME, it is important to make sure your training habits are set up correctly. Below are a few steps to follow. If necessary, you can also contact our team of expert advisors.

Step 1:

Exercise 3-4 times a week and do this with free weights (one-handed and loading dumbbells), also include "supplemental" cardiovascular training. When working out, focus on "double-joint exercises", i.e. bench press, squats with dumbbell, deadlifts and dumbbell pull-ups in the front. These four exercises stimulate protein synthesis, i.e. the formation of muscle mass, the most.

Step 2:

Eat 6 protein-rich meals a day. We recommend a protein intake of 2g of protein for every kilogram of your body weight, e.g. if your weight is 75kg, you need to take in 150g of protein per day. Make sure each meal contains healthy forms of carbohydrates and fats. The easiest way to manage all this is to take three complete meals a day (breakfast, lunch, dinner), supplemented with three more protein servings in the form of supplements such as protein drinks, bars etc (morning snack, afternoon snack, second dinner).

Step 3:

Prepare your body and mind for each workout. In addition to focusing and visualizing your entire workout, we recommend incorporating pre-workout supplements to help you get the most out of your workout.

Step 4:

Always make the most of the "GOLDEN TIME WINDOW", which is the time interval immediately after your workout when your body is energetically depleted and most importantly - OPEN for an extra intake of essential amino acids, proteins, carbohydrates and other nutrients. Take one dose of One Stop XTREME immediately after your workout to make sure your body is getting everything it needs.

Step 5:

Make sure your body is getting enough of all the important vitamins, minerals and healthy fats ( the base of the supplementation pyramid ) every day. One Stop XTREME provides you with a full daily dose of vitamins and minerals. For healthy fat intake, we recommend eating fish 2-3 times a week, or dietary supplements containing unsaturated fatty acids such as Omega 3, Krill Oil, etc.

Recommended dosage:

  • Mix approx. 70g of product (approx. 1 250ml scoop) thoroughly in 400ml of water in a shaker or blender. Consume immediately after mixing. Take 2 servings per day:
  • Training days: first serving mid-morning between meals (breakfast and lunch), second serving after training.
  • Non-training days: first serving mid-morning between meals (breakfast and lunch), second serving mid-afternoon between meals (lunch and dinner). Note: Dosage adjusted according to Czech legislation. The original British "hardcore" version recommends a limit daily dose of 290 g (2 x 145 g per day).

Warning. Do not exceed the recommended daily dose. Does not replace a varied diet. Store dry, cool, out of reach of children and sun. Close tightly after opening, use within 3 months or by expiry date if earlier. Package includes measuring cup. May contain traces of egg and soya lecithin.

S čokoládou to nemá nic společného. Strašná chuť. Možná se jim nepovedla šarže. Borůvka byla OK.
