Can't review since ordered was cancelled.
Ordered it like 2 times plus a different item and all my 3 items were cancelled. So I don't know how to review this until my husband gets back and gets to buy it through the store since yes it was free shipping for apo, but ordered was cancelled 3 times.

Buy it!
Besides the taste, it mixes well if done right. Been trying different brands and this one seems to make a slight difference.

Great Flavor
Gave it a three for great taste in the chocolate flavor. But did not see results in 2 weeks of use.

I’m currently in highschool football and once I started fluently taking this I made crazy gains every time I stepped in the weight room , this is worth every penny , taste is alright as well.

Big price tag, meh.
Good taste but the shakes are chalky. The product seems to be working as i feel my recovery time is getting quicker. Horrible gas though! I drink it before my workout because of the high carb content but it keeps me running to the bathroom. Price is too much, won't be using this again

Great taste and good gaining results but gives you gas
Vanilla flavor taste great. I mix it with outmeal and a little cinnamon for flavor and to add heartiness. It gives me a lot of gas and I seem to be having blood flow issues... a friend of mine told me to drink more water then I already do so that’s where I’m at right now

So far so good
Good product but gives you the farts the rest of the day. Don't use on days when you plan on having "relations" with a lady.

Not worth it
I bought this to try something new. i was intrigued by this have BCAA and Creatin in it, and it was only a little more than the ProBuilder weight gainer i usually buy. Its really not worth it, i find it harder to mix, thick and chalky and you end up drinking these massive shakes that leave me with a gut ache and burbs the rest of the day. I will be going back to Probuilder.

How to use to have a better results?
America S on Apr 6, 2018
BEST ANSWER: 3 Scoops with 16 oz of water after your workout, if you workout at night have it 3-5 hours before going to bed. but because of the 16g of BCAA and high protein it really helps with the gym aftermath and fuels your muscles.
