Why ANS N-Mass?
- 1,300 calories per serving — one of the highest-calorie mass gainers on the Canadian market, designed to drive serious caloric surplus
- 55g of protein from 3 sustained-release sources — Whey Protein Concentrate 80%, Milk Protein Isolate, and Micellar Casein deliver amino acids over an extended window, not just post-workout
- 32g of naturally occurring BCAAs per serving — supports muscle protein synthesis throughout the day and overnight
- 3g of Creatine Monohydrate included — supports strength and power output without needing a separate creatine supplement
- Zero added sugar — 250g of complex carbohydrates with only 16g of naturally occurring sugars; no fatty creamers
- Appelin™ + N-MASS Digestive Complex (Bromelain, Amylase, Lactase) — designed to support absorption of a high-volume serving and reduce bloating
- 6 flavours — Chocolate, Cookies & Cream, Peanut Butter Fudge, Salted Caramel, Strawberry, and Vanilla
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 supports serious muscle and weight gain when paired with a structured resistance training program. Best taken post-workout or between meals to sustain a caloric surplus, or mixed with milk before bed to take advantage of the slow-digesting Micellar Casein for overnight muscle recovery.
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 ✗ Individuals under 18 years of age — consult a 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 — that releases amino acids across a prolonged window rather than a single spike. This makes it effective both immediately post-workout and as a slow-digesting pre-sleep shake. The carbohydrate content comes from a complex carb blend (N-MASS Carb Complex), and healthy fats are sourced from coconut oil powder, MCTs, and flaxseed oil powder for a balanced macronutrient profile. Creatine Monohydrate (3g per serving) is included to support strength and power output, while the N-MASS Digestive Complex (Bromelain, Amylase, Lactase) and Appelin™ may help with digestion and absorption of the high-volume serving.
