This protein is the best protein in the world for people trying to gain weight.
All the flavours are amazing but I order vanilla because I feel the others are too dense
2018-10-26
My gym partner recommended me this protein and this page, and the truth is that I am very satisfied.

A classic for the time of volume for its result and its flavor. It's great and I won't change it
2022-05-17
Although the flavor is not the most determining factor, this one is great, especially the chocolate one.
2022-01-05
It is very balanced in its macro cast, although perhaps a little more protein would be ideal. Taste is really good and not cloying (biscuit).
2021-10-18
Quality like all ON products and at a very affordable price for this weight gainer.
2022-02-17
I USED TO TAKE ANOTHER WEIGHT GAINER, BUT THEY RECOMMENDED ME THIS ONE FROM THE OPTIMUM BRAND AND THERE IS A HUGE DIFFERENCE COMPARED TO OTHERS. I'M GETTING LITTLE BY LITTLE IN WEIGHT AND ONLY TAKING 2 SHAKES DAILY.

I always use this gainer at the times of the year when I need to gain volume fast because it works well for me
2022-08-03
It seems to me the best gainer on the market for its perfect balance of macros and efficiency, gaining quality mass.
2021-06-04
Weight gainer par excellence of serious athletes. It works well, reliable source and the flavors are very successful and all tasty
2021-09-02
A fairly powerful gainer in terms of calories, but with a very good distribution of macronutrients. It has helped me a lot to gain muscle mass without a lot of fat.
2021-06-02
One of the best gainers on the market and with the ones with the best results I have noticed. The relationship between its macronutrients is one of the most balanced I have ever seen. If you adjust the necessary amount well to your objective, the gains are of a high quality.
