Flavor tastes great, like hot chocolate. It mixes very easily in a blender but have to drink it in serving as it doesn’t fit in a 22oz shaker cup. Highly recommended to get in quick carbs and protein post workout or any time.

Great product! I felt I started gaining weight two days later after I started consuming. It can be easily digested but causes some bloating. I drank it before bed for weight gain. I gained 3 kg within a week, also The taste is very good.

Hard to get the whole shake down, however using whole milk, bananas and sometimes peanut butter makes the taste better and adds cals. Tastes pretty good

This is the best mass gainer I have tried. Great blend-ability. Been using it roughly twice a day between meals and the results a obvious. Starting about 4 months ago I have now gained 10lbs and my goal of benching 225lbs x 20 has been surpassed to completing 21 rep sets now. I began at 13reps. Overall body size has increased dramatically.

The Vanilla flavor is a little chalky once it comes to texture however, other than that once blended with the right mixtures, it"s flame! The Chocolate flavor is enjoyable. You DO get Results from this product as well, after a solid use of 3 months accompanied by intense work outs.

Flavour is great, tastes like chocolate milk. Scoops are large I did half servings morning and afterworkout/evening.

I started at 162LBS (6'2') and after taking this twice a day (1 scoop each time) I'm weighing 170LBS. about to order again and planning to eat more as well. Heres how I did it-- one scoop, 16 ounces of whole milk, a 3 scoops of ice cream, .. sometimes I would throw a banana or a tablespoon of peanut butter but that always made it hard to get down.

This is gonna help so much for me and I'm so glad I finally got mine! Just had a curious questions my nutritional facts are the one from Vanilla (I think) but I got chocolate Peanutbutter, but its no biggie, they aren't much different from nutritional facts, but taste is obviously different, im for sure going to buy another bag of this! Totally recommend for people who can't put on weight or trying to bulk up!

I use a scoop of this (625 cal, 25g of protein) and a scoop of syntha-6 vanilla protein. I blend it, and it comes out to 825 cal, 47g of protein after my afternoon workout. The flavor that comes out of this is awesome, tastes great and is filling as heck. Serious mass alone flavor is great too, I've put on roughly 13 pounds in 3 months, a lot of muscle but some fat included. It's just what happens unless you are tracking your exact macros/etc which I don't. Happy with this product

Really good mass gainer which helped me get 15 pounds of weight. I really like the chocolate peanut butter flavour. I took 2 scoops of mass gainer twice a day and beleive me it has seriously good results.

Great weight gainer- helped me put on 10kgs in just a few months. Doesnt mix particularly well, so I'd recommend a blender if possible. Choc Mint flavour has some poor reviews but I really like it (although it kinda grew on me- the first time I didn't like it that much). I split the portions into 2, as 1200 calories in a single hit is quite a lot. I have half a serving twice a day and have definitely reaped the rewards (especially coming from someone who struggles like hell to put on any weight). 10/10 would recommend.
