Product Overview

Rule One Mass Gainer is a high-quality weight gain supplement in powder form, specially designed for those who train hard and want to increase both muscle mass and body weight in a controlled manner. The package contains 2.62 kg of powder with a chocolate and peanut butter flavour, a classic combination appreciated by many. Rule One is a brand known for its strict focus on pure and effective ingredients, without unnecessary additives. Their philosophy is based on offering products that support active individuals' goals with well-thought-out formulations and high quality.

The mass gainer is developed to provide a balanced mix of protein, carbohydrates, and essential nutrients that can help you achieve your calorie surplus in an easy and tasty way. Rule One originates from the USA and has established itself as a reliable brand among fitness enthusiasts, thanks to its transparent product descriptions and focus on pure raw materials.

Active Ingredients 26 Science

The main ingredient in Rule One Mass Gainer is whey protein isolate, a pure and rapidly absorbed protein source that has undergone advanced filtration to minimise fat and lactose. This form of protein is particularly popular among fitness enthusiasts because it quickly delivers amino acids to the muscles after training. The carbohydrate component mainly consists of maltodextrin and dextrose, where maltodextrin provides a steady and slow energy release, while dextrose is a fast-absorbing sugar that can help replenish the muscle’s energy stores. Together, these carbohydrates provide a balanced energy supply for recovery and replenishment.

Benefits 26 Uses

  • Provides an easy and effective way to increase your daily calorie intake when regular food is insufficient.
  • Suitable for those who want to gain muscle mass in connection with strength training or other physically demanding activities.
  • Appropriate as a snack or meal replacement when you need extra nutrition and energy quickly.
  • The balanced composition of protein and carbohydrates supports steady energy levels and recovery after exercise.
  • The chocolate and peanut butter flavour makes it easy to vary and enjoy your nutritional drink.

Usage 26 Dosage

For best results, mix one serving (approx. 130 grams) with 300–400 ml of water or milk as desired. The product can be taken 1–2 times per day depending on your calorie needs and training volume. Many choose to consume the mass gainer immediately after training to quickly supply nutrients, but it can also be used between meals or as a convenient option when time is limited. For optimal effect, the product can be combined with other protein or amino acid supplements, but also as part of a varied and balanced diet.

Quality 26 Manufacturing

Rule One places great emphasis on product quality and purity. The products are manufactured according to high standards and undergo thorough testing to ensure content and safety. The whey protein isolate comes from controlled sources and the product contains no excessive additives. The packaging is sealed and airtight to preserve freshness and nutritional content throughout the shelf life. Rule One strives to offer transparent and reliable products developed with both the consumer and the environment in mind.

Who is the product suitable for?

The mass gainer is primarily aimed at adults who are physically active and have difficulty meeting their energy needs through regular diet, such as strength trainers, athletes, or individuals with a high metabolism. It is not intended for children, pregnant or breastfeeding women without medical advice. The content of milk protein, peanuts, and soy means that individuals with allergies to these should avoid the product. For those who want to gain weight in a structured and nutritious way, it can be a valuable complement within the framework of a balanced diet and regular training.

Summary

Rule One Mass Gainer is a well-balanced and flavourful powder for those who want to increase their body weight and muscle mass in a practical way. With a combination of fast and slow absorbing protein and carbohydrates, together with essential vitamins and minerals, the product offers a complete nutritional solution for active individuals.

Whey protein isolate in Rule One Mass Gainer has low lactose levels due to filtration but may still contain traces of lactose. People with severe lactose intolerance should check the product label carefully or consult the manufacturer before use.
How long does a 2620 gram package of Rule One Mass Gainer last?
The duration depends on how many scoops you use daily. A typical scoop weighs about 150-200 grams, meaning a 2620 gram package lasts between 13-17 days with daily use, but this varies depending on individual dosing.
