One of the best

Have been using this for a good year and is my one and only choice. Overall, not as sweet as other brands used. Great gainer for my body type.

Great flavor and not too sweet!

Thankful for prompt delivery of product. Very good on the digestive side of things. Overall, great between meals to keep metabolism working and have another serve before bedtime so that my body is being rejuvenated whilst asleep. Ready for next busy day. Recommend this product.
