Optimum mass

I buy this product for my son. He is 18 and gaining weight in conjunction with weight training. He loves Optimum Mass. Optimum Nutrition offers the bigger bag which is very hard to find. My order always comes in time.

I’ve been using Serious Mass for a month now I can say there has been a difference in my body. More toned and gained muscle too. Still got a long way to go. The taste is okay but I usually mix with peanut butter, banana, milk and water - it taste much better that way.

Vanilla is best
