Love both!! But the peanut butter is better. No after taste!

  • 9 Vanilla Ice Cream

The nutrition facts and all are objective, so form your own opinion there, but subjectively, the taste and blendability in my opinion are top tier. One of (if not THE) best protein powders I’ve ever purchased.

  • 10 Strawberry Milkshake
  • 6 Chocolate Peanut Butter
  • 9 Banana

Loved this as a protein shake! I found that the chocolate peanut butter flavour was a little chunkier and didn't mix as well but the banana was much smoother. It was also one of my favourite protein flavours I've had! Results were fantastic with the blend of proteins.

Alright, so I was a bit skeptical about this product at first, I mean the package just look outdated and cheap, and what's up with this complex protein blend, why couldnt they just put 100% whey right? Oh man, I've never been that wrong in my entire life. Let me get this straight, so there's no confusion about it; THIS IS THE BEST SUPPLEMENT I HAVE EVER BOUGHT. Thats it! There is no "but", it's the best, peridod. I mean, I dont know if it's the actual blend combining fast digesting and slow digesting protein, or if I just needed that extra carbs and fat this product contains, but I have seen so much improvements in my workouts since I switched from ON gold standard to BSN syntha-6, it's insane! I would definitly recommend this product to every skinny ectomorph out there trying to gain mass. It won't make you pill some fat like a weight gainer, and it give you more for your money then a regular whey supplement. No complaints what-so-ever, this is the ****!

I always seem to come back to syntha 6. It's good protein that tastes great and mixes extremely well. The high calories are a down side.

  • 10 Chocolate Milkshake
  • 9 Cookies & Cream
  • 8 Strawberry Milkshake

Mixability is the best, flavor is amazing. Doesn't get you bloated, has some sugar. I take this protein for building rather than cutting, and i really like them. Anyways, it is just protein, and if you are on a budget, due to the price, i would go for something else. If you can afford them, go for it, it won't make much of a difference but they are just perfect.

  • 9 Chocolate Milkshake

Best protein product I have ever used by far. Have had better gains (and better cuts) on this product than any I have ever used before. The quality of the protein is second to none.

I have tried just about every protein on the market and Syntha 6 is by far my favorite! It's not the lowest calorie or the lowest fat but the macros are still great. One of the few protein shakes that mixes equally well with water OR milk. I love that there is added fiber and that the sources of proteins are blended. I've never had a protein that I like better. Muscle Pharm's Combat Powder comes close in SOME flavors but EVERY single flavor of Syntha 6 I've ever tried is 100% legit. Also this powder is a great flavor addition for plain oatmeal and making pancake batter. Gotta try it!

My favorite flavor of protein by far!!! It may not have the greatest macros (but they still aren't bad) but it's worth finding a way to make it work in your diet.

Verified Buyer

I wouldn’t waste my time writing a review on a product. But!!!! After tasting the strawberry milkshake flavor it was only right that I did . This flavor/Product is probably the best tasting I ever had in my life!!! Definitely recommend this! Just get it you won’t regret it trust me!

  • 7 Chocolate Milkshake

The flavour is fine but I dont understand, how can people say its a great whey protein when out of a scoop of 47g, only 22g is protein??!!! Thats lesser than 50%! Is everyone on some heavy drugs here?
