I have been using muscle blaze xxl since a month.Though the weight gain was not much just only 1 kg, but this product helped me to gain big muscles, such as biceps and chest.
Usually I was a skinny guy until the last 4 months, but after using this product and doing the gym, I have become a bit bulkier.
Talking about the flavour, it is not as good as born vita or horlicks, but still you can adjust.
The packaging is good and tightly sealed.
Therefore if you wish to gain some muscles faster, you can try this product as its price is less than that of other supplements
