I'll Pump You Up



BSN Syntha-6 Isolate protein is a high quality isolate matrix that will fuel your hard working muscles with amino acids and protein. BSN’s supplement promises to deliver a moderately paced release of amino acids to constantly drip feed your muscles the necessary fuel to initiate protein synthesis and help you reach your muscle building goals.

Let’s dive in and see how BSN Syntha-6 Isolate stacks up to its competition.


Taste and Mixability:

Syntha-6 Isolate is a 100 percent isolate protein matrix that comes in various delicious flavors: chocolate milkshake, strawberry milkshake, vanilla ice cream and peanut butter cookie. Our favorite flavor is the chocolate milkshake, but all four flavors are incredibly delicious. The mixability is also very good, as this protein powder will easily mix in a blender bottle or a standard shaker cup.


BSN Syntha-6 Isolate is priced at little more than $1 per serving, which is on the high side for a protein powder supplement. Although it is priced higher than most, it also contains higher quality protein sources with its protein matrix of whey protein isolate and milk protein isolate. This gives you a nice combination of fast and slow release proteins for moderate release of key muscle building amino acids. You are also getting 25 grams of protein per serving.

The best price we found for a 4.01 lb tub (48 servings) was $51.99 at



BSN Syntha-6 Isolate is a highly effective meal replacement protein supplement because it contains the perfect ratio of fast and slow release proteins. This will help to drip feed your muscles with anabolic fuel – as opposed to a faster digesting protein source that will instantly penetrate your blood stream. This can be used as a high quality meal replacement protein supplement or a normal post workout shake.


Side Effects:

Since one of the main ingredients is Sunflower powder consisting of sunflower oil, corn syrup solids and a few other artificial sweeteners – several people with allergies have complained of stomach problems. This was not a regular occurrence and only happened in a small percentage of users.

For For

  • Plenty of protein (25g)
  • Fast and slow release protein sources
  • Great taste

Against Against

  • Quite expensive
  • Contains 7g of carbohydrates


BSN Syntha-6 Isolate – Our Verdict:

BSN Syntha 6 Isolate is a delicious whey protein powder that contains a nice ratio of fast and slow release proteins for a moderate release of amino acids. The only downside to this product is the addition of the sunflower powder, making it not the ideal choice for someone looking to cut body fat. This is however a high quality meal replacement protein powder, and comes in three delicious flavors.
