Who Is This For?

ANS N-Mass is designed for hard gainers, ectomorphs, and athletes in a dedicated bulking phase who cannot consistently hit their calorie targets through whole food alone. It helps you add calories for weight gain when paired with a structured resistance training program. Take it post-workout or between meals to keep a calorie surplus, as the label directs.

Who Is This NOT For?

✗ Anyone not following a structured resistance training program — high-calorie intake without exercise may lead to unwanted fat gain ✗ Individuals with dairy sensitivities — contains Whey Protein Concentrate, Milk Protein Isolate, and Micellar Casein ✗ Those in a cutting or calorie-deficit phase — this is a purpose-built bulking supplement ✗ Anyone pregnant or nursing — the label says do not take this product if you are pregnant or nursing ✗ Individuals under 18, or anyone with a medical condition (including diabetes or hypoglycemia) or taking prescription or over-the-counter medication — check with a qualified healthcare professional before use ✗ Anyone sensitive to sucralose or acesulfame potassium — check the label before purchasing


What's In It?

N-Mass is built on a three-source protein blend — Whey Protein Concentrate 80%, Milk Protein Isolate and Micellar Casein. The carbohydrates come from the N-MASS Carb Complex, and the fats from coconut oil powder, MCTs and flaxseed oil powder. Each 4-scoop serving also includes 3g of Creatine Monohydrate, 200mg of Appelin™ (alfalfa sprout, caraway, orange bioflavonoids, ginger) and the N-MASS Digestive Complex (Bromelain, Amylase, Lactase).

⚠️ Allergens: Contains ingredients from milk, coconut and soy; Peanut Butter Fudge also contains ingredients from peanuts. Warning: Do not take this product if you are pregnant or nursing. Check with a qualified healthcare professional before using this product if you are under 18 years of age or if you have any known or suspected medical condition(s) including diabetes or hypoglycemia, and/or if you are taking any prescription or over the counter medication(s). Keep out of reach of children. Check the allergen statement and warnings on your bag. Always read the full label before use.

Frequently Asked Questions

How many calories are in ANS N-Mass per serving?
ANS N-Mass delivers 1,300 calories per serving (4 scoops / 330g). Each serving also provides 55g of protein, 250g of carbohydrates, and 9g of fat. New users may start with 2 scoops (approximately 650 calories) to assess tolerance before progressing to the full serving.
How do you mix ANS N-Mass — water or milk?
Mix 4 scoops of ANS N-Mass with 500mL (16.9oz) of cold water in a shaker cup or blender and shake for 30–60 seconds. For a thicker shake with additional calories and protein, mix with milk instead of water. Mixing with milk is a popular choice for a pre-sleep shake due to the added casein protein.
Does ANS N-Mass contain creatine?
Yes. ANS N-Mass includes 3g of Creatine Monohydrate per serving. This means you don't need to purchase a separate creatine supplement while using N-Mass, making it a convenient all-in-one mass gainer for athletes focused on muscle gain and strength performance.
Can ANS N-Mass cause bloating or digestive issues?
ANS N-Mass includes Appelin™ and an N-MASS Digestive Complex (Bromelain, Amylase, Lactase). Because the full serving is large, new users are advised to start with 2 scoops mixed in water before progressing to the full 4-scoop serving. N-Mass contains ingredients from milk, coconut and soy (Peanut Butter Fudge also contains ingredients from peanuts), so anyone with those allergies or with dairy sensitivities should check the allergen statement on the bag.
Is the ANS N-Mass sold at Bulldog Nutrition authentic?
Yes. Bulldog Nutrition is an authorized Canadian and US retailer of ANS Performance. Every tub of ANS N-Mass is sourced directly from the brand — 100% authentic, never grey market or counterfeit. Bulldog Nutrition has been online since 2016, serving customers across Canada and the US.
