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 763 calories with 55 g of high quality complete dairy proteins, mostly from isolate sources to help you grow bigger and stronger when taken in conjunction with an exercise program. The carbohydrate blend includes oat, pea and potato, and the fats include medium chain triglycerides, chia and flax. We took it a step further by making the powder easy to mix in a shaker cup. No blender needed. There is no doubt that GOLD STANDARD GAINER™ raises the bar for weight gain performance.

Review by Naren on Aug. 10, 2022
It’s really good

Gainer Pro

Review by Anonymous on Jul. 29, 2022
Mixed well, personally like the chocolate more but the vanilla mixes extremely easy for some reason... Is quite a bit more sweet than the chocolate flavor but none the less is very nice for what it is. Both chocolate and vanilla mix well, but chocolate seemed to take a little more shaking. Would definitely recommend for anyone looking for a product of this nature, flavors are excellent, mixes well with milk, (I haven't tried water) and also hasn't caused any stomach issues or anything for me personally.

Best product out

Review by Arson on Jul. 17, 2022
Have been using the pro gainer for a year and was able to put on 8-10 pounds. Switched over to gold gainer and now I’m 20 pounds. Work out consistently 5 times a week with high intensity training. Recommend for people who have trouble gaining / keeping weight and not looking for that bloated feeling afterwards.

Absolutely amazing taste!

Review by Doug on Jul. 15, 2022
So far, 1 week in (after 3 weeks of vacation and being away from a gym...) already regaining size and definition.!

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

Great taste
