Review: Best Protein in - Great protein! This is my second bottle and will be buying again! Super easy to mix no clumps or bad taste! The flavor is really spot on! I take 2 scoops in the am and pm! It is just the same as the other whey proteins but less expensive!
Review: Delicious not chalky - I’ve been drinking SYNTHA-6 Ultra Premium Protein – Vanilla Ice Cream since 2018, and it’s still my go-to. The flavor is honestly what keeps me coming back. It actually tastes like vanilla ice cream -smooth, creamy, and not overly artificial. No weird aftertaste, no chalky texture. It mixes well with just water, but it’s even better blended with almond milk or in a smoothie. What I love most is the consistency. Same quality, same taste, year after year. It’s easy on my stomach, keeps me full, and fits perfectly into my routine whether I’m using it post-workout or as a quick meal replacement. If you’re looking for a protein powder that doesn’t taste like you’re forcing yourself to drink it, this is it. Been loyal since 2018 and not switching anytime soon.

## Questions & Answers

**Q: does this product contain any carbohydrates, if so please explain**
A: Yes it has about 15g of carbs. 5 grams fiber and 4 gram sugars. You can also see nutrition facts in pictures for more details.If you are looking for zero carbs go for dymatize ISO-100 vanilla in our amazon store.Thanks and have a great one.

**Q: How sweet does it taste? it feels like on puts way too much splenda/sucracose, and i want to try something new..that tastes less sweet**
A: I haven't tried it. But my husband uses it everyday and says it tastes just like a strawberry milkshake.

**Q: how many calories in a drink?**
A: READ THE LABEL!!! Duh

**Q: i am 19 years old,5'9 and 160 pounds... im trying to grow some mass...will this help me??**
A: Protein powder is always a great thing to have in order to get at least your body weight in in protein grams. One needs to eat every 2-3 hours. Food is the key to getting huge and strong in the gym. One needs to get in their body weight in protein grams consistently and this kind of protein powder will help you because let’s face it, it’s easier to drink a good protein drink verses chew through another meal. Obviously you don’t want to have nothing but protein powders. You would live on the toilet. I like to have a shake usually a couple times a day with two scoops with ice cold water. I usually have it in-between each of my solid meals. I do every other meal with a shake. If you are eating consistently through the day and getting your body weight in in protein grams, your results in the gym will be so much more paid off! You need it to grow. I have used this brand for a number of years. I go back and forth between only a few of my favorite national brands and bsn is one of them! Optimum Nutrition and Muscletech are the other two. Get your protein in with at least 160 grams a day. Realistically you should be getting in at around 240 grams of protein a day to keep growing and recovering from your workouts. It’s hard but worth the sacrifice. God bless!
