Optimum Nutrition Serious Mass, Weight Gainer Protein Powder, Mass Gainer, Vitamin C and Zinc for Immune Support, Creatine, Chocolate, 6 Pound (Packaging May Vary)

I’ve been using Serious Mass for a few weeks now, and it's been super helpful for adding extra calories to my day. I’ve always had a hard time gaining weight, and this makes it way easier to get in the calories and protein I need without feeling like I’m constantly eating.The chocolate flavor is actually really good—especially when you blend it with milk, peanut butter, or a banana. Just a heads-up, the serving size is huge (like, 2 giant scoops), so a blender is a must. Don’t even try mixing it with a shaker bottle.I also like that it includes creatine and some vitamins, which saves me from buying those separately.Only downside is it can feel a little heavy if you’re not used to big shakes, so I started with half a serving and worked my way up. But overall, it’s been awesome for helping me bulk up. I’m already seeing some gains.

Buen producto y llegó el día ofrecido. Muy bien.

This mass gainer mixes smoothly and tastes great. It’s packed with calories and protein, making it perfect for bulking. I've noticed steady weight and muscle gain with consistent use definitely effective!

Buen sabor no he visto resultados grandes todavia pero si se notan algunos cambios pequeños!

Es muy buena, la he usado varias veces y me funciona y me ha hecho aumentar de forma sana.

My son has been using Optimum Nutrition Serious Mass for a few weeks and he loves it. Each serving is packed with over 1,200 calories, which makes it easy to hit your daily intake goals without force-feeding. The Chocolate flavor blends well with milk. He didn’t milk the taste when mixed with water. Just a heads-up—start with half a serving if you’re new to weight gainers.

The metrics on this are good in terms of calories and and protein but it has some issues. First the scoop is insanely large. This makes it difficult to even mix 1 scoop with milk without it being super thick. Secondly it doesn't really mix well. Even when using a bullet blender it still clumps pretty hard. lastly the residue it leaves behind is very hard to clean. I'll use it until it's empty and look for something else.

First of all I tried the vanilla and the chocolate flavor. Please do yourself a favor and only get the chocolate flavor. Listen, the chocolate flavor is the same in every other brand protein shake or mass gainer because they all use cocoa powder. So if you like chocolate you will not be surprise when you taste it. Compared to the vanilla one which has a very unique taste that I did not like. Just get the chocolate one.Also, the servings say two scoops but if you have not seen the scoop it is the same size as a detergent scoop. It is even hard to take it out of the bottle. One scoop is enough for one serving (625 calories). If you do decide to take two scoops space them out throughout the day. I do not recommend this though since you should be getting the rest of your calories and nutrients from real food. One scoop every day is fine though.Ok, so how did I mix it? I used a electrical blender. I have used a shaker bottle with the metal spring ball thing before since I did not have a electrical blender in my college dorm. But it taste much better if you blend it with an electrical blender because you will not have large clumps. Also, you can add other ingredients if you like such as peanut butter (chocolate flavor + pb taste freaking good just like reeses cup). Peanut butter adds more calories and protein to your shake. Do not take this mass gainer if you are not working out at least 3 times a week. You will simply gain a gut around your stomach area unless you are anorexic. Even if you are anorexic, you should still work out. And if you are like me and are still looking to add calories to your serving, add in 1 tablespoon of olive oil (120 calories), and you will not taste as long as you drink fast enough so the olive oil does not float up after you blend it.So my shake usually is 1 scoop (625 calories, 24g protein), 12fl oz of milk (225 calories, 12g protein), 2 tbsp of peanut butter (190 calories, 7g protein), 1 tbsp of olive oil (120 calories). Total of 1160 calories, 43g of protein (hopefully my math is correct).With all of that being said, I recommend to buy Optimum Nutrition 100% Whey Protein (Extreme Milk Chocolate flavor) instead of serious mass because this gainer has a ton of carbs. The first ingredient is Maltodextrin which is normally found in soda and candy. You save a lot of money also since the whey one has more servings.Last advice, use MyFitnessPal app if you have trouble gaining weight. Make sure you are actually hitting your calories goal. I used to think that I had a fast metabolism because I ate so much. But in reality after I calculated the calories, I was far away from hitting 3000 calories.I gave it 5 stars because it worked for me. I went from 145lbs to 160lbs in three months. Yes I gained fat but also muscle because I worked out. I no longer take this after finding ON 100% Whey. Much cheaper per serving, a better selection of flavors, and a lot less carbs. Yes, it might not have the calories but you can definitely create your own mass protein shake by using the correct ingredients. Google svunt shake if you need an idea of creating your mass gainer with whey protein (it has 1659 calories and 95g of protein).Have fun gaining.
