Optimum Nutrition Serious Mass

I recommend this product to anyone that wants to get big. ON is the best brand of protien.

I like it. It mixes well, contrary to popular belief. Tastes pretty decent, a little floury, but I can live with it.

As the name suggests this is a very serious product with some rather impressive numbers. Unfortunately in order to get those impressive numbers in one must use two gigantic scoops that I found nearly impossible to consume. The serving sizes are simply huge with my 5.45kg bag containing a mere 16 standard serves. A fantastic product that does take a bit of getting used to.

I have been using serious mass for a long time now, after trying quite a few mass gainers before it. The total number of calories is what does it for me, cant find it anywhere else and the chocolate flavour is pretty dam good. I drink it warm like milo. I usually struggle to eat enough calories in a day for really good muscle growth but i find the job a lot easier with this product. Thank you optimum nutrition!

The serving size is huge, and the mix-ability of the powder itself is very average. The chocolate taste pretty good though. However, I can see this product working within the first couple days of using it, putting on close to 0.6kg already. The results can only get better from here. I would question, however, whether a normal protein/carbs mix would result in the same as serious mass if it were taken in the same quantity.

Being 6'2" and 57kg's, I had serious issues gaining weight regardless of anything I try. A PT gave me about 2kg of this supplement and I immediately liked the taste, consistency and results that I noticed. As soon as I ran out of that amount, I purchased a 5.5kg bag of Serious Mass from Mr. Supplement and noticed immediate results. In one month, I gained 7.3kg of muscle and mass, I still remain quite lean and toned but my weight is skyrocketing! The recommended amount is two HUGE scoops but I've found that one scoop mixed into full cream milk gave the most noticeable results. The chocolate flavour was tasty and mixes well and the results speak for themselves. I have often used Serious Mass as a meal replacement with no issues and it is honestly one of the best weightgainers for any hard gainers like myself.

Since using Optimum Nutrition’s “Serious Mass” I have noticed a huge gain in weight. I stacked on 4kg within the first 3 weeks and then another 3kg in the 3-4 weeks following. I was worried that the calories would make a huge increase to my BF% but it didn’t seem to impact me that much. I was using half a recommended serve each time and having 2 shakes a day which worked fine. In terms of taste it is definitely one of the harder proteins to drink but not that bad if mixed with chilled water. After finishing the bag I have moved onto ON 100% gold standard to lean up but will definitely use Serious Mass again when going through a bulking stage of my workouts. I would definitely recommend this product for any hard gainers or people who are just trying to supplement some needed calories into their diet.

I have done a lot of research about the best weight gainer on the market and Optimum Serious Mass kept coming up. I purchased it with great hope that I would see results, within 2 weeks I have noticed lifting gains and my weight sessions tend to be more intense now. The product recommends you take 2 scoops in a serve but I found if I did that a normal size shaker would not fit it all in so I took 1 scoop before my workout and 1 scoop after my work out. The strawberry taste ok but the mixabilty is very poor and I recommend using a blender. Overall I think this product is going to work wonders by going what I have seen in the past 2 weeks, thanks Mr S for the top advice.

After reading good review online about Optimum Nutrition Serious Mass, I decided to give it a try in order to gain some much needed. I went with chocolate flavour to be safe, and it didn't disappoint! It tastes delicious in comparison to other gainers I've tried, and allowed me to take in my needed calories to gain weight. It contains a huge amount of calories and protein in each serve allowing an ectomorph like me with a fast metabolism to put on some weight. I've been through one bag already, and gained around 3kg which I'm extremely happy with considering how hard it is for me to gain weight. Definitely recommend Optimum Serious Mass to anyone who has a hard time putting on weight, or is in need of serious calories in their diet. Another great product, Will be buying again soon!
