Full description




EFECTIV MASS is a scientifically formulated hard gainer formula designed to support anybody whose goal is to increase bodyweights and build muscle tissue.

Each 250g serving packs in over 900 calories, less than 10g of sugar and over 45g of protein, with over 17g of total branched chain amino acids (BCAA’s).

We’ve used a carb blend including rolled oat flour, maltodextrin, and sweet potato to provide sustained release, quality carbohydrates. Also added are healthy fats from coconut milk powder, quinoa and MCT’s.

As to be expected from EFECTIV, our mass gainer comes in three delicious flavours and mixes incredibly well.

Each bucket contains 20 servings based on the recommended 250g serving size.


Milky Choc Flavour

Carb Blend (Rolled Oat Flour, Maltodextrin, Sweet Potato), Protein Blend (Whey Protein Concentrate (Milk), Milk Protein Concentrate (Milk), Skimmed Milk Powder (Milk), Hydrolysed Egg White Powder), Cocoa Powder, Coconut Milk Powder (Milk), Quinoa, Flavour, BCAA (l-leucine, l-isoleucine, l-valine), Micronized L-Glutamine, Sunflower Lecithin, MCT (medium chain triglycerides) (derived from Coconut (Milk)), Thickeners (Acacia Gum), Emulsifier (Xanthan Gum), Sweetener (Sucralose), Digestive Enzyme Blend (Amylase, Lipase, Protease), Vitamin & Mineral Blend.

Recommended Use

Mix THREE scoops (250g) to 500-600ml of chilled water or to your preferred flavour requirement, shake vigorously for 30 seconds using a shaker or using a blender. Once mixed consume immediately.

For greater accuracy use weighing scales as scoop provided is included as a tool. We recommend 1-2 servings between scheduled meals per day and/or directly post intense exercise.

When first using this supplement, it is advisable to start using a half serving to assess tolerance.
