ON Gold Standard Mass Gainer

Gold Standard Gainer is Optimum Nutrition’s balanced mass gainer built for quality calories — not just sugar. It combines a multi-source protein blend with complex carbohydrates (oat & grain-based) and supportive fats for a thick, milkshake-style gainer that’s easy to use daily.

• High-calorie gainer with balanced protein, carbs & fats
• Designed for steady weight gain and recovery
• Thick, milkshake texture — great taste & mixability

*Flavour availability can vary by batch.

• Quality calories: Macro-balanced to help you hit a surplus consistently without relying on straight sugar.
• Multi-phase protein: Fast and slow proteins support immediate recovery and sustained amino delivery.
• Carb matrix: Oat/grain-based carbs help replenish glycogen with a smoother sweetness.
• Easy to stick with: Thick, dessert-like flavours you’ll actually enjoy daily.

Stack idea: Post-workout Gold Standard Gainer + 3–5 g creatine; add fruit or nut butter if you want even more calories.

Typical Ingredients: Protein blend (whey & milk proteins), carbohydrate blend (oat & grain-based carbs), fats (including MCTs), flavours, sweeteners, emulsifiers, thickeners. Ingredients may vary slightly by flavour.

Gold Standard vs Serious Mass?
Gold Standard Gainer focuses on quality calories with a thicker, oat-style profile; Serious Mass pushes even higher total calories per serve.

Water or milk?
Water mixes lighter; milk adds creaminess and extra calories. p>

Can I split the serve?
Yes — many users do 1 scoop twice daily if a full serve feels too heavy at once.

Creatine stack?
Great post-workout stack: add 3–5 g creatine monohydrate.
