Product Overview

Protein & Carb Muscle Recovery Formula

GOLD STANDARD GAINER is built on a foundation of complete dairy proteins, mostly from isolate sources. 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. This is the new Gold Standard for weight gain support.

It wasn’t for me

Review by Leo on Oct 2, 2022
I wish the label was on the website so that I could see the sodium amount on this new product. The previous product had less. The customer service and delivery was on another level of greatness. I will definitely buy from them again. I will give 2 starts for the gainer I bought, but just for the customer service and delivery, I will give them 5 starts.

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.
