Overall the taste is good

Overall the taste is good and for the price you get a good size tub of weightgainer. A couple minor gripes is that the scoop size is not like your Typical scoop—it’s like a shovel. Won’t easily fit into most shaker cups which makes For some tricky, awkward mixing. Also the powder is so fine that the slightest sharp movement will result in powder all over yourself! All in all it tastes good; not the best for easy quick mixing but the price is pretty fair for the quantity. Worth trying once

Does the trick

I got the banana flavor and I didn’t mind the taste. I mix one scoop with water and will take another scoop later in the day. Super easy way to pack on the calories. Plus, it isn’t chalked full of sugar. The only bad thing is the price, but you get what you pay for I guess.
