Great taste and easy to consume. Makes workouts and muscle growth simple, especially with a busy lifestyle like mine, which can make it hard to consume enough calories without supplements.

Probably the best tasting protein powder I've had in a long time. If you're looking to gain weight (or "serious mass"), i highly recommend this product. Great amounts of Carbs, Protein, and Fats with perfect blends of vitamins. You can't go wrong in my opinion

At this stage I can't fault the product. Price wise is about $6 per shake, one shake is 1250 calories plus protein and carbs, vitamins etc. One a day to help boost that intake is only $6. Great value.

In the past I have tried the chocolate flavour but i found it too rich, hard to get down. Vanilla on the other hand is not too rich and like most other vanilla shakes, you can always add additional flavours, berries etc to give it a kick or remove the vanilla flavour entirely. Same cant be said with Chocolate though.

All in all, great product, good value and coupled with Mr Supplement delivery and all round great base for training supplements.

By far the best mass gaining protein I've tried. Tastes like chocolate brownies and it's easy to mix. A lot of calories per serve which is great, it's been the only protein that's helped me to put weight on. I have an incredibly fast metabolism but since taking this / lifting regularly I've gained 10kg over the past 8 months. No longer referred to as the 'skinny girl' and I couldn't be happier!

I bought this product for my son who has a fast metabolism and medication that decreases his appetite, making him very underweight.
I am very impressed with the results, he has gained 3kgs in 7 days.
Highly recommend and will be buying again.

If you want to gain mass but also do a lot of cardio based workouts then this definitely works well.
I went from 66kg up to 83kg within a few months.
Definitely recommend!

I've been consuming this gainer for a week and I just got 1~2kg. I'm not sure if I can keep gaining weight tho. It tastes awesome with milk.

Great product to get that extra mass. I'm a seasoned weight trainer and wanted to build up a bit more mass (I can only eat so much). I've gained a kg per bag but only at a half serve each time blended with milk, taking it on waking, after training and at night before bed. I should also note that I've seen a increase in my strength as well.

This was first mass gainer supplement I have taken and I am amazed how much of a difference it made to my weight. I managed to gain 2.5kg in a week and a half.

This is my guide for new people who wants to gain weight:
You have to blend it, instead of shaking because when you shake it, it will form clumps and you don’t want that. The guide tells you to blend it for 30secs but I only blend my 10secs on low because I don’t like air bubbles.

I recommend mixing this powder with milk, first you get extra calories (extra 250calories – one scoop of powder and 6oz of milk) and second, it tastes fantastic! And this is coming for a person who struggles to drink milk.

Before I mixed the powder with milk I tried water and boy let me tell you it tasted awful! When you mix it with water it tasted bland, it tasted like cheap chocolate milk, it tasted bland, there was no texture, it is like drinking milo but with lots of water, sculling it was difficult. However it doesn’t affect this product only, it affects across all protein/weight gain powder. Want to enjoy drinking the mix, mix it with milk trust me, you’ll understand why it tastes so good! Rich in texture, and delicious.
Take one serving a day, I struggle to drink a serving at once because you end up having to drink 1200mL after blending. I usually split the serving into two, half a serving in the morning and another before I go to bed.

Want to gain weight? Eat food while you drink this supplement, it makes it easy to consume lots of calories in one go. Generally make the most out of this mass gainer drink, try mixing it with other ingredients like honey and squeeze extra calories into the mix. The supplement isn’t cheap and this is coming from a uni student where everything is a luxury.

Results? I regret not eating enough when I had this (since I was a uni student I only managed to eat 2 meals instead of 3) however I was surprised to gain 2.5kg in about a week and a half – I weighed 66kg but now I weigh 69kg. Which was pretty good.

I recommend this product because it has the highest calories per serving compared to other mass gain products.

Not a fan of the taste
I usually have no issues with the taste of ON products but this one...I find this product difficult to take on it's own. Probably better mixing it with something with stronger flavours...but honestly - who has the time for that? I'd probably go with another gainer personally.

I was just wondering how many times a day I should take this and how much?
How much you take is dependant on your body type and diet. Have at least one full serve per day if you find that you struggle to put on weight. Otherwise you can have half a serve per day.
I just want to know if serious mass contain all the amino acids like it counterparts 100% whey protein which have all the EAAs, NON-EAAs and BCAAs in it?
Optimum Serious Mass shall NOT contain the concentration of Aminos that Optimum 100% Whey Gold Standard shall contain.
