In the vast sea of the protein powder market, BSN has released "an ultra-premium sustained release protein powder" formulation named Syntha-6.

The majority of protein powders are a relatively simple mixture of whey protein or isolate, with the addition of artificial coloring and flavoring agents to make the product more palatable. Syntha-6 departs from this mold by including ingredients that serve to delay the process of digestion, thus in theory providing sustained levels of amino acids in the blood.

Sustained Release Blend of 6 Proteins

Six types of fast and slow digesting protein comprise the blend. The addition of calcium caseinate and micellar caseinate support the claim of sustained release, as both are slow digesting proteins, while the first ingredient, ultra-filtered whey protein concentrate, digests more quickly.

Also, the addition digestive enzymes "Aminogen®" and Papain is a welcome addition to the formula, as they may help alleviate stomach upset associated with protein powder consumption.


BSN lists several product highlights. Let's examine some.

"Produces 'ridiculously' delicious protein drinks that maximize lean muscle development". I must admit that this protein is extremely delicious. It is easy to forget that you are chugging down a protein powder and instead believe you are savoring a refreshing and tasty smoothie.

The product tastes exceptionally well when mixed in a blender with milk and banana. Please keep in mind that because of certain proteins found in Syntha-6, the product will not dissolve as easily as an instantized whey protein isolate.

"Doesn't leave you feeling bloated or stuffed: Great for several-times-daily use". The degree to which an individual may tolerate this product, or any protein powder for that matter, is dependant upon the individuals ability to digest milk derived protein powders.

Personally, this product seemed easy on the stomach, but as the servings per day increased, so did the incidence of slight stomach discomfort. Syntha-6 seemed to (more so than other protein powders) keep my appetite suppressed for a substantial duration of time.

"Doesn't leave you feeling bloated or stuffed: Great for several-times-daily use."


Overall, I am impressed with Syntha-6. It seems as though BSN is gaining momentum in the supplement industry and because of products such as Syntha-6 and NO-Xplode, such a trend is no mystery.

The product provides the user with a delicious way to consume necessary levels of protein, which is for some a huge chore and inconvenience. Along with the premium features it affords, so too does it come with a premium price.

At nearly the same cost of a 5 lb container of "100% Whey" by Optimum Nutrition, the 2.91 lb Syntha-6 may not be within everyone's budget. According to BSN, Ronnie Coleman's favorite protein is the Strawberry Syntha-6, sorry Ronnie, but I'll take the Mochachino.

BSN Syntha-6 Review: By Dave


I used sample packets (one serving packets) of the Chocolate, Mochachino and Vanilla flavors, each of which I mixed in 1 cup of 1% milk. My taste review of each is as follows:

Chocolate: Distinct milky chocolate. Great choice for those who appreciate a milky chocolate taste. This is the good taste I have come accustom to and expect from the BSN line of supplements. Would purchase again.

Mochachino: If you like Tim's Iced Caps, you will love this flavor. Personally, I don't even like Iced Caps. However, I still enjoyed the taste of this flavor, despite how much I dislike Iced Caps.

Vanilla: Delicious creamy vanilla taste. Great choice for those who appreciate a creamy vanilla taste. Would purchase again.

As you can see, I thoroughly enjoyed each flavor and wish I had more to sample! Flavor-wise Syntha-6 receives a score of 9.5/10. This is near the highest rating I will give because no matter how good something is, there is always room for improvement.


Although I blended Syntha-6, rather than using a shaker, I only did so for a matter of seconds and it was ready to go. However, most protein mixes I've tried take longer than this. Therefore, it receives a score of 8/10.


As with any protein supplement review, it is difficult to evaluate the overall effectiveness of the product. The reason being, unlike creatine and pre-workout amplifiers there is no significant effect. The purpose of protein is to either get extra calories in your diet or to be used as a meal-replacement on the go.

Also, protein supplementation may be used in place of an unhealthy meal, which would be detrimental to an individual seeking an improved physique. Since I began working out, protein shakes have been a part of my daily diet. The convenience of a protein shake is too good to not take advantage of.


Syntha-6 cannot be beaten in taste to date. Also, it has a high protein content per scoop. However, Syntha-6 has its negatives. Syntha-6 is an expensive choice of protein.

As good as Syntha-6 tastes, I find it has a high fat content for a protein powder. Therefore, it may not be the best choice for the individual attempting to avoid fat. That being said, in the correct moderation, fat can be a healthy part of a diet. However, I would not recommend taking this as a late night snack. In light of all that, it receives an overall score of 8/10.
