Optimum Nutrition Serious Mass Weight Gainer Protein Powder, Vitamin C and Zinc for Immune Support, Vanilla, 12 Pound (Packaging May Vary)

I picked this a couple of summers ago to help keep weight on me. I tend to lose a lot of weight in the summer because I work outside a lot. This year was no exception and this stuff is absolutely amazing! It mixes up so well, I can work out with it, which helps build muscle, it helps my energy level levels., The ingredients are everything you need in a daily supply and the taste is great. I always mix mine with frozen fruit or peanut butter.!

Loved The Taste It’s So Good & It Work GreatJust mix it in your shake, I use bananas, peanut butter, milk, and oats

I’ve been using Optimum Nutrition Serious Mass for a while now and keep coming back to it because it delivers consistent results. It’s a great weight gainer with plenty of calories and protein to help me build muscle and add mass.The added creatine is a nice bonus, supporting my strength gains and recovery. The taste mixes well and isn’t too sweet or chalky, which is a plus compared to other mass gainers I’ve tried.If you’re looking for a dependable product to help with weight gain and muscle building, I’d definitely recommend Serious Mass. I’ve bought it over and over again and plan to keep doing so!

Tastes good and delivers great macros however the quantity you need to consume a single serving is massiveIf you want to blend two heaping scoops, which is one serving, and want to drink something that's less solid than concrete, you'll need to drink 5 or 6 pint glasses of this stuff.This isn't a quick, easy, dense way to get 1500 calories. It's a tremendous effort.I'm sure the ON mix is cleaner, but you can get easier calories with a 16" steak and cheese sub, and be less full.

Quality, dissolves easily, Taste is great. Love it already. Packaged properly.

Highly recommend serious mass , I’ve been using it for 2 years, the results are fantastic. With serious weight training.

Bought this for my girlfriend to help her out some weight on and it has worked well so far. She loves the taste we mix ours in a ninja blender so its like a milkshake. We use whole milk and add peanut butter to up the calories and protein content. Plus it's a 12 pound bag it's huge and it works enough said it works.

This is the first time I’ve actually finished a full container of a mass gainer, and while it helped me gain about 5 lbs (alongside eating more), I had some struggles with it too. I got the vanilla flavor, and it was extremely sweet—to the point where it felt like a sugar coma every time I drank it. I normally don’t eat sweets, so I believe this sudden sugar intake caused a noticeable acne breakout on my face.Like most gainers, it’s heavy on the stomach and made me feel bloated for hours, which made it hard to eat proper meals after having a shake. That said, it does mix very well with no clumps, and the texture is smooth and creamy.I’m not sure if vanilla is just the sweetest flavor, but I’m hesitant to repurchase unless I try a different one or find a cleaner option. It works, but there are trade-offs.
