great but costly

I have no idea why someone would buy this tub when it is less protein and more expensive than the other tub sizes. With that being said, you are getting the same great protein as you would be getting if you purchased any of the other tub sizes. BSN syntha 6 is one of the best protein blends on the market today. It can be a little costly if you buy it in the smaller tub sizes, but wither way the money is worth it. It will give you some good protein that your muscles need.


Good quality protein

Syntha-6 is a great quality protein that taste great and get the job done every time whether it be after a workout or if you need to get some extra protein in during the day.

Great product, good choice

I have gone through a few tubs of Syntha-6 Isolate and it has done me well. Nothing crazy but expected gains with a good tasting product. Has a good multi-release protein matrix which makes it good to use even before bed. It is in my Top 3 proteins for sure.


Very good protein but definitely doesn't live up to the Syntha-6 taste.

This product is very good as a protein. BSN I'm sure tried their best to make the product taste as what Syntha-6 should taste like but I assume that one can only do so much when the only protein sources you are using are isolates and probably more whey isolate than milk protein isolate. So the product mixes very thin and watery. The flavour isn't anywhere near as decadent as regular Syntha-6, but for an isolate, it's really not bad and better in taste and texture than many other pure isolates on the market.


Awesome taste and product!

Love to take this protein post workout or whenever I need to get some more protein or need a sweet tooth fix. Helps with recovery and the taste is incredible!
