Gain the Gold Standard advantage with this colossal weight gainer, designed to maximise muscle growth, enhance recovery and pack in high-quality calories for maximum benefit. Gold Standard Gainer by Optimum Nutrition contains 770 calories, 55g of protein and 112g of carbohydrates, delivering everything the body needs to pack on muscle gain.

Optimum Nutrition is the consumer’s brand, with innovative products, the industry standard quality assurance and consistency of product development, unlike no other brand. Utilising a key 4-way protein blend, accompanied by a multi-stage released high-quality carbohydrate blend and quality fats from MCT oil and chia seeds, Optimum Nutrition’s Gold Standard Gainer is truly the pinnacle of sports performance supplementation.

What are the benefits of Gold Standard Gainer by Optimum Nutrition?

  • Build muscle mass, gain strength and hit weight goals
  • Protein and carb muscle recovery formula
  • 55g of high-quality protein (Complete Protein from Primarily Isolate Sources)
  • 750-770 calories from quality ingredients
  • Fats from flax, chia and MCTs
  • 109-116g of carbohydrates from oat, pea and potato
  • 2:1 ratio of carbohydrates to proteins
  • Informed Choice Certified - Trusted by Sport
  • For a higher standard of muscle

Protein Blend

Utilising a 4-way blend of whey protein isolate, whey protein concentrate, milk protein isolate, and hydrolysed whey protein isolate offers a premium blend of high-quality amino acids with a multi-phase release of critical amino acids for muscle growth, as well as muscle preservation.

Carbohydrate Blend

Unlike most cheap weight gainers, the Gold Standard carbohydrate blend utilises pea starch, potato starch, oat flour and maltodextrin, keeping the sugar content under 10% and offering a high-quality, steady-state release of carbohydrates into the bloodstream. Controlling blood sugar levels means fewer insulin spikes and reduces the risk of heavy energy crashes.

Fat Blend

The consumption of MCTs has been linked to improving energy production, supporting a healthy metabolism and delaying glycogen depletion, as well as being further characterised as a muscle energy source as opposed to being stored as adipose tissue.

Your expectations will not be let down with Gold Standard Gainer. Containing only the highest quality ingredients we have become accustomed to from Optimum Nutrition, Gold Standard Gainer is a great nutritional addition as well as being the perfect product for enhancing recovery and muscle growth.

BETWEEN MEALS: Mix up 1 scoop of Gold Standard Gainer between meals to help support a high calorie diet. 

POST WORKOUT: Mix 1-2 scoops of Gold Standard Gainer in 10 - 20 fl oz of milk or water 30 - 45 minutes following exercise to support maximum recovery. 

BEFORE BED: Mix up 1 scoop of Gold Standard Gainer about 45 - 60 minutes before bed to help muscles recover while you sleep.
