10/10 Chocolate

It is a good product and its taste is very good.It gives a good energy.

10/10 Vanilla

I swear this reminds me of pancake mix but so much better. Mixes very well with water (if you don't like milk) and tastes very good. One of my favorite weight gainers.

10/10 Strawberry Milkshake

I've used BSN's True-Mass previously and found it to be a good product. So far it's working well alongside an increase in daily food intake. Up 4 kgs in 7 weeks! I purchased Strawberry which is actually quite nice and mixes well. Sprint Fit's price was better than others I compared and the free next day delivery was outstanding. I'll definitely buy from these guys again.
Great taste and mixability, as always fast shipping, great service!

7/10 Vanilla

9/10 Chocolate

Good product, vanilla is not the best flavour.
Have tried other mass gainers before and this is the best. Being out of the gym after elbow surgery I had lost a bit of weight. I was able to exercise but not do weights. I was down to 84.6kgs. 4 weeks after being on true mass I'm up to 87.5kgs and have lost excess fat around my mid section. I will definitely keep buying. The flavor chocolate milkshake tastes good and it does not have that plastic/fake taste that you sometimes get with other shakes
Love this product, been helping me with gains as I'm someone who finds it hard to gain mass.
First time ever tried mass gainer. Bsn product is great and really delivers but you gotta be careful you diet right and workout otherwise u wont hit that sweet spot of muscle mass gain. Strawberry was top notch but heard choc is just as good.
Recommended to me by my gym instructor I decided to try BSN True-Mass. I noticed gains even using a reduced serving size. Every muscle I exercised was getting thicker and harder. My 2.6kg tub lasted me roughly a month this is a good mass gainer and i recommend it to anyone who is trying to gain weight or put on some bulk. Thanks to Sprint Supplements for the advice also.
