Gold Standard Gainer

  • 55 g of high quality protein
  • 771 calories from quality ingredients

Product Overview


Size is an advantage in many sports, but some athletes have a hard time gaining weight. You can only eat so much food, so we formulated GOLD STANDARD GAINER™ with quality calories in a 2:1 ratio of carbohydrates to proteins. Each full-sized serving weighs in at 771 calories with 55 g of protein to help you grow bigger and stronger when taken in conjunction with an exercise program. With high quality protein and complex carbs from oats and starch from pea and potato, GOLD STANDARD GAINER™ raises the bar for weight gain performance.


Carbohydrate and protein powder with sweetener. Protein contributes to growth of muscle mass. Carbohydrates contribute to the recovery of normal muscle function after highly intensive and/or long-lasting physical exercise leading to muscle fatigue and the depletion of glycogen stores in skeletal muscle. This benefit is observed with an intake of total carbohydrates at 4 g per kg body weight, at doses, within the first 4-6 hours, following exercise. Protein & Carb Recovery Formula Nutritionals refer to Colossal Chocolate flavour and may vary

5lb in `1 Month

Review by Ralph on Jun 9, 2022
I was able to gain 5lbs in a month 2x a day, also with creatine, cant really ask for more

Optimum Nutrition Gainer (Gold Standard)

Review by John M on May 30, 2022
Mixes quite well for how much you actually consume in a single 20oz cup... Very little clumps if shaken well enough and also very easy to get down as the flavor is excellent. Haven't been taking it long enough to get the results yet, but it definitely feels as though it'll put the weight I'm desiring on me. Overall, seems to be a great Mass Gainer.

The weight gainer i feel good after taking

Review by Roger on Mar 3, 2022
The best weight gainer i ever tried. I feel good after taking it every time.

Great Recipe - Sad its discontinued

Review by HS on Jan 19, 2022
This was the best product in terms of combination of high calories, high protein, and complex carbs rather than bad carbs. Sad to hear that it has discontinued due to every other recipe lacking in one of the three things stated above. Hope to see it back someday!

Good stuff

Review by Anonymous on Nov 27, 2021
Tastes good and does the job recommend using a smoothie maker to mix it for the best results as it's quite thick

Uitstekende smaak & samenstelling. Wel prijzig zoals alles van Optimum Nutrition.

Preis ist hoch aber die Qualität auch

Review by Quaresmaa on Apr 23, 2019
Ich habe früher verschiedene Gainers benutzt und dieses Produkt ist das Beste was ich probiert habe. Es ist teuer klar aber das Geschmack ist echt gut( es ist süß aber das Produkt enthält fast gar kein Zucker). Wenn man Geld hat ist es sinnvoll dieses Produkt zu nutzen weil die Kohlenhydrate hohe Qualität haben.
