BSN Syntha-6 is one of the most talked about protein powders in the market, but how effective is it really?

After scouring the net for the best protein supplements, we eventually came across with BSN Syntha-6. BSN Syntha-6 is a creation of BSN, a known brand in the supplements industry. With the numerous reviews we’ve encountered, it became known to us that BSN Syntha-6 is best known for one function:

BSN Syntha-6 is indeed, delicious.

In fact, BSN Syntha-6 is marketed as “The best-tasting protein shake”. While that title is debatable, there’s surely no denying that BSN Syntha -6 is palatable for many.

Still, the more important question that needs to be answered is – is BSN Syntha-6 effective?

It seems that the priority of BSN when marketing Syntha-6 is just selling it based on its taste and nothing more. Any serious athlete, whether amateur or professional, would tell you that the taste wouldn’t matter as long as the product works. It seems to us that BSN doesn’t get that if customers wanted tastier shakes, they would have drank milkshakes instead. What about the real benefits that the customers are looking for? That’s what we tried to find out with this review.


BSN Syntha-6 claims that it provides an essential function much needed for exercise and bodybuilding – sustainable protein to achieve muscle recovery throughout the day. According to the product literature, BSN Syntha-6 is composed of different proteins that break down differently.

In theory, having different paces of digestion means that BSN Syntha-6 can provide a steady source of protein over a longer period of time. We put this theory to the test, and our results are not quite what you’d expect.

For our first trial of BSN Syntha-6, we measured the effectiveness of 1 serving. The product promised better muscle development by giving muscles the time to recuperate, and by providing the necessary protein that allows muscles to repair throughout the day.

The first thing that we noticed is how quickly our test subjects got side effects from BSN Syntha-6. Some of those who used BSN Syntha-6 reported an upset stomach, some had dehydration issues and some even had gas problems. As a protein shake that’s supposed to replace meals, having these side effects could greatly alter someone’s day-to-day life should they continue using BSN Syntha-6 regardless of how effective it is.

The effectiveness of BSN Syntha-6 cannot be accurately measured, since its effects are highly dependent on the physical activities of the user, and their individual diet as well. This is consistent with the majority of customer reviews we’ve read on bodybuilding forums, with much of the users raving about the taste rather than what BSN Syntha-6 is supposed to do.


BSN Syntha-6 boasts a combination of 6 proteins, each with different paces of digestion. These proteins are in the form of:

  • Whey protein concentrate
  • Whey protein isolate
  • Calcium Caseinate
  • Micellar Casein
  • Milk protein isolate
  • Egg albumen
  • Glutamine peptides

It looks good on paper, but until you measure the actual protein content, you wouldn’t see how it really fares against similar products.

BSN Syntha-6’s protein component has a total of 22g, or 44% of your daily allowance. Many other protein supplements have a much bigger protein concentration per serving, and they do not break down over a longer period of time – which leads me to believe that the gradual absorption of protein may even be too small to discern any benefit.

Pros of BSN Syntha-6:

  • Great-tasting
  • Displays information about ingredients
  • Fair reviews online
  • Sustained protein absorption

Cons of BSN Syntha-6:

  • Side effects
  • Very minimal protein absorbed over time
  • Expensive
  • Too much artificial flavoring that may contain high doses of sugar

The Takeaway:

It’s an established fact that we need protein that will be absorbed over a period of time, but you’re better off sticking to your regular diet if your protein shake doesn’t give you the amount of protein that you need to feed your muscles. You also need to consider that BSN Syntha-6 may be loaded with artificial flavoring that takes points off of its nutrient value. It’s clear that with this product, BSN gave more weight to the taste than its actual effects.

What we recommend:

NitroGenix 365 is the right brand for people who want visible results right away. It’s the perfect balance of protein, nutrients, and hormone boosters to give you the ripped body you want – FAST!
