This stuff tastes great. Adds the calories you need after a workout and keeps you from getting hungry and cheating in the afternoon after my workout. It is a little hard to mix but really works.

I tried Optimum's other mass gainer, the gold standard one, and it was way too sweet. This product tasted great. I also saw barely any progress while on the Gold Standard Mass Gainer but this one proved to be great. Amazing for hard gainers like me.

My teenage sons (17/19) are hard gainers. They have had great success in making muscle gains and maintaining mass with the help of this product. We've used this before bedtime for over a year and will continue doing so. We mix on scoop with 10-12 oz water in a shaker...mixes great...like all good things...you have to be consistent with a good diet as well...this is a supplement if you're looking to gain mass.

Tastes great, doesn't always mix well, but way better than other powders tried in the past. Banana cream pie tastes like artificial banana flavored milk when mixed with milk.Oh and takes longer to mix with a portable battery blender, or mixes even less with a hand shaker. I really like the strong artificial banana flavor so that's a plus to me.

Tastes alright, mixed relatively well given the large serving size. I was just disappointed in the amount of servings you get. I should have paid more attention to that, as 14 servings for $90 is a bit insane. That being said if you're willing to pay it I would recommend this. It's never been easier to take in 60 grams of protein.

This is an excellent gainer that helped me quickly gain 20+ pounds of mass in a few months. It mixes in a shaker cup excellently. It’s a big scoop but one scoop and some milk and it doesn’t even come out overly thick. I don’t mix with anything just the powder and milk and take post workout or before bed depending on when I trained. I don’t eat like a bodybuilder and do not have a big appetite but this product helps me get 3500 cals a day in everyday with a minimal effort and I have put on a small amount of fat but the mass I’ve put on is quality and I credit this gainer for being the most beneficial thing I do along with counting cals/ macros on an app on my phone.

Every since i wanted to get bulky I read about pro gainer. But before that ON has never let me down so I tried to purchase it. Honestly vanilla is the way to go but i had gain gains as soon I killed the tub I purchased the bag. Sure feels like a rice bag. I totally recommend if your trying to get heavier on your weights as well weight but I got the serious mass too and it sure works good too. Keep doing well ON.

I am not a big food/eating person so this gainer really helps. Product mixes very well. I don't usually use a mixing ball and after some vigorous shaking there are no/very minimal clumps. Tastes great for what it is. Has that typical funny aftertaste that any mass gainer has. Double chocolate is great with fruit and other carby foods in a blender for a huge carb packed shake after training. Love that is also has 60g of protein to really help me hit my macros. Taste the gains!

I am almost finished with a 5lb tub of this stuff and I have not had any increase in weight but I have made gains in muscle tone and strength. Now this is not to say that this product would not help you gain some weight in muscle but I do have a really fast metabolism. I am 5'8 and weigh 132 pounds so it is hard for me to pack on any mass. I orignally started looking into weight gainers in ordered to gain some weight and muscle but that quickly turned into me just looking looking to maintain my body weight as a more realistic goal. Before I started working out really consistently about 8 months ago I had lost 6 pounds (from some where) and I quickly maxed out and this product has helped me put back on 4 pounds of it in muscle in about 2 months. Overall I love the flavor, the ease of mixing and overall effects of this product and plan on buying more soon.

Product is great but do NOT get banana cream pie unless you love those little marshmallow peanut chewie candies because it tastes exactly like that. Gross to me

I workout for 2 hours a day every day. This product not only helped me gain the muscle I am trying to build but also gives me the amount of energy and recovery I need to go just as hard the next day. Double chocolate also tastes great and the powder mixes easy.
