STAY AWAY !!!!!!!
Used to love this product. They changed something and it's not terrible. The first ingredient is MALTODEXTRIN. Look up that. It's a sugar supplement that's not real sugar but acts as one. Protein concentrate. So processed protein Go down the line of actual ingredients. Artificial flavors and Sucralose. This used to be a great product. Now it's just absolute garbage. Diabetics in a bag disguised as protein powder. Sad because I took this for years.

Shawn's review
I take this and I use the vanilla, for when I bulk up starting October every year until April. I try and have my calorie intake at 3000 per day at least 5 days a week. I mix it with peanut butter, quaker oats, honey, almond milk and a banana. taste damn good. I take it right after i workout. I workout mostly in the evenings after work, just good enough for the shake and bedtime after, I also eat 4-5 meals a day when I bulk up as well.

Pros/Cons
Four starters I have been trying to put on weight for why do while within two weeks or less with the amount I have consumed I have gained maybe 5 pounds for me Adam water to mix this product is not a good idea unless you doing it in a blender obviously sometime I am on the go so I have a nice long spoon and a cup with milk and it makes very well with milk the vanilla taste it?s good and I don?t like vanilla very much is store-bought the smell is perfect if you take this product and you don?t eat anything you consume a lot it will mess your stomach up or if you eat a very small meal and consume more of this product it will mess your stomach up to each his own there is not a lot of the product inside of the container it?s like half air which is empty try to do some type of exercise after consuming this product instead of laying around and not doing anything any kind of exercise it takes a while to see a major increase on your weight gain journey no matter if you take two full scoops twice a day it takes a while and if you?re not a milk drinker the taste gets on bearable on a regular basis other than that you will have to see any additional results this is my experience

Effective
The powder is very chalky and not easily mixable. Taste is ok. However if you are a hard gainer or needing meal replacement this will help you get what you want and hopefully graduate to something stable afterward.

Pretty good
Its only been a solid 2 weeks, so its too soon for me to really give my opinion on the gainzz .Flavor isnt too bad. I got vanilla, I always go with chocolate but the savings deal only had vanilla flavor to offer. I just straight chug my whole shaker. Goes down smooth. The scoop is big, think of a detergent cup and thats your scoop. Ive been fairly consistent with it. Twice a day on workout days and once a day on non workout days. It has given me the extra strength. Its an overall good product. I would definitely go for chocolate next
