Optimum NutritionSerious Mass Protein Powder High Calorie Mass Gainer with Vitamins, Creatine and Glutamine, Strawberry, 8 Servings, 2.73 kg, Packaging May Vary

I’ve been using this for a while and I’ve gained so much more weight in the gym. I is easy to mix with other flavours which has made drinking my shakes more enjoyable.

I'm pretty fussy when it comes to Protein Shakes.This one however, for a mass gain shake is surprisingly tasty.I tend to make it in the morning, chuck it in the fridge and then drink it in the evening... keeps it smooth, no bits and tastes good cold.I recommend this as a mass gainer shake.

Definitely working for me, however...the standard serving is HUGE and way too much for me. Even splitting in half I found it bloated me up so much I was wasn't eating as much, hence defeated the object!This is what I have found best after trial and error..I personally have two shakes a day but less than half the standard amount in each.I add 350-400ml of semi skimmied milk into the shaker. Then add 100g of powder (put the milk filled shaker on some scales before adding the powder) but also a heaped teaspoon of cocoa powder. This makes a big difference to the taste as without it, the taste isn't that great (for me). Certainly not your usual chocolate milkshake taste without the extra cocoa. Doing this, there is no problem with mixing/lumps. Shaker is fine. This portion size also makes the tub last a lot longer.I have one of these after breakfast and one after dinner. This adds 1000 calories each day to my diet. Have gained several pounds in less than two weeks. Key is to keep eating as you do normally and drink this AFTER eating.Hope this helps.

Normally with shakes I use milk so tried milk first of with this product and was very thick, clumpy and found it very sickly. So since then Iv been doing it with water and it’s a lot nicer, mixes well and far less sickly so would recommend doing it that way 👍 all in all happy with the product and after trying several different weigh gains off amazon I would recommend this one

I bought the banana flavour but it’s too sweet and this makes it difficult for me to take it everyday. I am not sure i will get the expected results when i am not using it consistently.

I brought it for myself and it helps me to gain weight and build muscles. I gain 2 kg weight in just one week.I use it after doing gym and i found it very helpful for muscles recovery. Value for money and its vanilla flavours taste amazing😋Higly recommended to all.
