Ag116797I've had like 6 flavors of flavcity protein powder all of them with the exception of the butter coffee tasted delicious. But yeah that getting down that butter coffee flavor was brutal.
Aggravating_Lemon874I actually like flavcity protein. Tastes delicious and smooth, no weird after taste. I’ve been buying them from tik tok shop when there’s a sale at almost half the price and free shipping. It’s higher in calories but works for me as I don’t need to add any additional fixins to make it taste better.
bowinkle1969I always buy the peanut butter chocolate. Taste great, seems to be a high quality type of protein powder
brandirose72FlavCity but you can only get it at Target right now or the FlavCity website (cheaper at Target). It’s all delicious and clean.
CleriisyWe have very different tastes lmao. I got some Flavcity protein packets from a Strava promo...worst protein powders I've ever tried. The Butter Coffee specifically was nearly inedible.
fayeray311It's pretty pricey, but the Flavcity protein powder is the best I've ever had. They have lots of flavors too.
