Loved the taste and quality.

Syntha-6 is by far the highest quality protein powder that I have ever used. The taste cannot be beat! When everyone says it tastes just like a real milkshake, they are not lying. I would drink other brands of protein over the sink in case I had to throw up from the taste being so bad! Also, this really stepped up my game in my weight loss and muscle gaining goals. Before I took the protein i would feel weak after working out since I was on a calorie deficit, now when I drink my shake i feel full and satisfied after my workouts. I gained a noticeable amount of strength and muscle volume once i started religiously drinking Syntha-6. It has been a year long journey and over 80 pounds of fat lost,and I could not have done it without the help of and Sythna-6.Cannot recommend this product or company enough!

Syntha-6 has to be the best tasting protein around. I only complain about the servings per container, this is where I feel they lack. aside from the great taste its a thick shake when mixed with water and you don't need to mix 2 scopes for volume or substance. I believe I could replace a meal with this shake, overall great product just need more serving per bottle. 48 servings isn't competitive- 9

I really look forward to drinking these shakes any time. They really taste that good. The vanilla ice cream for me is ridiculously good. I drink it at LEAST 3x a day. I ended up buying a 5lb tub. The protein is moderate and has some carbs and fat but unless you're prepping for a competition or something this is perfect for people trying to get supplement their protein intake or just live a healthier lifestyle.

Actually bought this elsewhere as delivery to New Zealand can be slow and I'd run out. Tastes great though (and I should have read this first), it's got corn syrup in it which I really don't expect from something in a sports supplement. Is sucralose not a better option? I know it's a popular protein but in my 40gram scoop I think if like more protein and less fillers - especially the corn syrup

Only Strawberry flavored protein mix that I've enjoyed other than Max Muscles brand. Good taste and doesn't give you that metal aftertaste many Strawberries do.
