Description

Product Overview

Reflex Nutrition Instant Mass Heavyweight is a high-calorie powder designed for those looking to add extra energy and nutrition alongside strength training and muscle building. The generous pack size lasts a long time, making it suitable for both everyday use and intensive training periods.

Reflex Nutrition is a British brand with extensive experience in sports nutrition. The company has built its philosophy on science and quality, focusing on offering products that meet the needs of both elite athletes and dedicated fitness enthusiasts.

Active Ingredients & Science

The protein in the product consists of several fast- and slow-digesting sources to ensure a steady supply of amino acids.

Benefits & Uses

  • Can be used as a convenient meal between meals or after training to support recovery.
  • Easy to mix and adjust to your own needs, both in flavour and quantity.

Use & Dosage

The recommended dose is usually 2–3 scoops (approx. 100–150 grams) per serving, mixed with 300–400 ml of water or milk. The product is flexible and can be adjusted to suit your individual energy needs. It can be taken immediately after training to provide nutrients to the muscles, or as an extra snack during the day when calorie requirements are high. For best results, follow the product's dosage instructions and combine it with a varied diet and regular exercise.

Quality & Manufacturing

Reflex Nutrition places great importance on the quality and purity of its products. Instant Mass Heavyweight is manufactured in modern facilities that comply with strict hygiene and safety standards. Production follows GMP (Good Manufacturing Practice), and the product contains no unnecessary additives or fillers. Each batch undergoes thorough testing to ensure accurate contents and high purity. The packaging is designed to preserve the product's freshness and shelf life, with clear storage instructions.

Who Is This Product Suitable For?

This mass gainer is primarily intended for people who train regularly with a focus on strength and muscle mass, such as gym-goers, bodybuilders and other strength athletes. It is also suitable for those who find it difficult to meet their energy needs through food alone, for example during periods of high physical activity or when trying to gain weight. The product is not recommended for pregnant or breastfeeding women without medical advice. It contains milk protein and should be avoided by people with lactose intolerance or a milk allergy.

FAQ

Frequently asked questions about Reflex Nutrition Instant Mass Heavyweight

How is Reflex Nutrition Instant Mass Heavyweight absorbed, and what affects its absorption?
The product contains whey protein concentrate, maltodextrin, oats and creatine monohydrate. Whey protein is broken down into amino acids during digestion, while the carbohydrates are broken down into sugars. The product also contains milk, peanuts and soya.
How should Instant Mass Heavyweight be dosed, and when should it be taken?
The manufacturer's recommended serving is 2 scoops, approximately 150 g, mixed with 300–400 ml of milk or water. Drink one serving daily, preferably after training or as a snack to increase your calorie intake. Follow the serving instructions on the packaging and include the serving in your total daily intake. Mix well before use.
Can I combine the product with creatine or other supplements?
One serving contains 5,000 mg of creatine monohydrate, so check the contents of other products before combining them to avoid consuming creatine from multiple sources without accounting for the amounts. The product also contains vitamins and minerals. If you take medicines or several supplements at the same time, ask a pharmacist or healthcare professional whether the combination is suitable.
What side effects or contraindications should I be aware of?
The product contains milk protein, peanuts and soya, so it is unsuitable if you are allergic to any of these ingredients. A large serving may feel filling or cause stomach discomfort in some people, particularly those who are sensitive to dairy products. The product is not vegan, but is suitable for vegetarians.
Can I mix Instant Mass Heavyweight with milk instead of water?
Yes. The manufacturer states that the serving can be mixed with 300–400 ml of milk or water. Milk gives a different flavour and consistency from water and contributes its own nutrients, which are additional to those in the product. If you avoid milk or are allergic to milk protein, do not use milk as the mixing liquid; the product already contains whey from milk.
How should the product be stored?
Follow the storage instructions on the packaging and keep the product tightly sealed in a cool, dry place, protected from direct sunlight. Use a dry scoop and avoid letting moisture get into the container. Keep it out of reach of young children. Once mixed, a serving should be consumed straight away rather than stored for a long time.
