This is very good for gaining mass. I put on 27pounds in 2 1/2 months, and still gaining. This would be good belnded into a shake, but as you know we dont have time for that. USE WATER! and shake until there is little to no residue at the bottom and drink it fast. Dont concentrate on the taste because you will find yourslef not wanting to finish it. If you can take it, it packs on pounds. However not a good tasting one. I prefer the Hyperbolic mass gainer by GNC. This is the best, goes down smooth, and tastes better than strawberry milk!

Great Product
I Tried the product with Milk alone at first and it wasnt bad, I realized that taking a full serving after working out did make me feel very bloated so I proceeded to take half a serving after working out and then a full serving before bed and over the course of a a month I have gained 6 lbs since using this. Recently I changed up mixing it with milk and started mixing it with orange juice and putting a banana or two in a blender and mixing it all up, works great.

This product helps me to maintain weight and gain muscle. I use it after meals at least twice a day.

Great product!
I take this product every morning after breakfast and it works great! I only take half the serving because I feel too bloated otherwise. I've seen gains since using this product- about ten pounds over the course of three months. Tastes great, somewhat like juice. I didn't notice a chalky taste, but that might be because I only use half a serving with 20 oz of water.

Worked for me
Used about half the recommended amount per day and gained about 5+ lbs in about a month. Seemed to be muscle weight I gained. Also focused on eating well/more and worked out pretty hard 3+ times per week. Was lifting more weight after a month.

Strawberry Review
The taste is horrible, I would stay away from this flavor. I thought I would try strawberry because the banana was so good but it tastes like your drinking water with chalk in it.
