Review: Taste is on point - Fantastic protein. Flavor was on point it mixed well I use milk in a shaker bottle and it mixes easily. It even has little pieces of birthday cake like confetti I love it. It's been easy on my stomach and digest well.
Review: When taste is king - Birthday cake tastes great with just 5 or 6 oz of water. I thought I had clumps but it's sprinkles. The powder looks like you could add eggs and milk and oil to make funfetti cake. i'm buying this flavor again soon but will try something else from them first. The scoop must be dug out but you're used to that but for the fun sprinkles i added a point back on value. If you like to blend until totally smooth then move along to another flavor for shaker bottle. Cost efficient and taste great although some of the sugars are there it's tiny and some eaas is great sooooo worth it by far for me. I was always buying on price point and suffering or paying for so/so gnc brand at a premium so I tried some from a brand I always saw and what a difference! I use it for a lunch replacement and as an appetite suppressant so time will tell how filling it is. It came a full year and a half from expiring so that is huge for me because I know the flavor is there. the stores keep any price of stuff on a shelf too long. stop wasting money and try my new favorite from desertcart. Super happy with this right now.

## Questions & Answers

**Q: does it work?**
A: Sure it works, if you work!

**Q: This package is not coming with a spoon, from where can I find one?**
A: Oh no......oh no. Ever try and find the plastic wrapped prize in those cereal boxes of the 80's? Same deal here....1) roll the tub with the cap closed at a slight angle until you think you see the 'spoon' through the clear-red container....2) open your tub and fish for it the rest of the way. You ring true to the phrase, "We lift heavy things and put them back down"....the struggle is real......3) Enjoy :)

**Q: Why do you put so many unhealthy ingredients in your product- sugar, corn syrup, wheat and corn flour? So many better wats to get you protein!!**
A: SYNTHA-6 has always been a flavor first protein powder. Regular consumers are willing to sacrifice a few more calories and carbs to enjoy phenomenal flavor.

**Q: Can I make Cold Stone ice cream with this?**
A: You can make a high-protein dessert that tastes a lot like Cold Stone ice cream. There are recipes for using protein powders to make ice cream-like treats available online.
