I've just finished my 3rd bag (Over about 3 months) and went from 205 -> 220. Was hoping to end up around 235 but I'm married so I never get what I want.

Flavor Name: VanillaSize Name: 12-Pounds Verified Purchase
I just finished taking the whole bag. If you are thinking about buying it, here is my two cents:

1) Its scoop size is enormous (a giant baker's cup or 8.45 oz/250 ml plus). I've uploaded a picture of it against a generic protein powder scoop (1.8 oz/70 ml). With two recommended giant scoops per serving we are talking about tons of calories here.

I only use half a scoop at a time mixed with half of a generic scoop of soy or whey protein to prevent fat gain, but still get a good amount of protein and some needed calories without bloating my stomach. I consume about 6 mixes a day.

2) If you are also taking multi/vitamins/minerals/enzymes like Animal Pak while heavily training, be mindful that this weight gainer has some too. Do not overload your liver. What I do is take only one pack a day of Animal Pak against the recommended two.

Flavor Name: ChocolateSize Name: 12-Pounds Verified Purchase
Tastes great with milk, mixes in pretty well in a shaker. Makes a good meal replacement, 1250 calories for less than 3 bucks. Only reason this has 4 stars is because the bag it comes in is faulty. I bought two and on both the zipper broke off immediately, so now I have 24 pounds of protein unsecured, exposed to air

Flavor Name: ChocolateSize Name: 12-Pounds Verified Purchase
To begin, the serving sizes are unrealistic, I drink 1/3 of a serving three times a day with a mix of 1 and 1/2 cups of whole milk and water. The taste is mind blowingly delicious though (obviously the milk will do that) and I actually look forward to drinking it. I've gained about 3 pounds after using 3/4 of a bag, but more impressive are the gains made in the gym. For example, my bench press went from 185 to 225; about 160% of my bodyweight. The only downside I could think of is that the powder is as fine as the purest sand from the Sahara, the slightest nudge and your house looks like a woodshop.
