C9-T11 2.0 Review and Product Info

C9-T11 2.0 is advertised as “The world’s most powerful anti-catabolic muscle growth formula.” Today we offer our C9-T11 2.0 review along with additional product information.

We first discussed the original C9-T11 product in October 2012. Since then, the C9-T11 formula and marketing have both changed. Today we’re taking a look at the 2.0 version of C9-T11 a little closer.

C9-T11 2.0

The official website remains unchanged, and can still be accessed at In 2012, the website focused on “700% more muscle in 7 weeks.” In 2013, the 2.0 version of C9-T11 highlights the “anti-catabolic power” of the product, and its cortisol-lowering properties.

C9-T11 vs C9-T11 2.0

The original C9-T11 only contained a single active ingredient:
1000mg CLA Complex (75% Conjugated Linoleic Acid).

C9-T11 2.0 contains three active ingredients:
50mg Vitamin C, 50mg Phosphatidylserine, and 900 mg CLA Complex (72% Conjugated Linoleic Acid).

It appears that the addition of phosphatidylserine is what separates the original C9-T11 with the 2.0 version.


Although phosphatidylserine has been studied and listed as possibly effective for neurological benefits, it has also been cited in recent years as a means to reduce cortisol after exercise. Most studies, however, have focused on much higher doses than found in C9-T11 2.0.

This study in the Journal of the International Society of Sports Nutrition, for example, found that 400mg was not sufficient to lower cortisol: “The results of our study showed that 14 days of supplementation with 400 mg of PS had no effect on serum cortisol or total testosterone levels.”

Another study of a much higher dose found that, “In a double-blind study of active young men, supplementation with 750 of soybean-derived phosphatidylserine per day for 10 days increased the time the men could exercise until exhaustion by approximately 25%.”

C9-T11 2.0 recommends one to two pills a day, which only amounts to 100mg of phosphatidylserine.

Alternatives to C9-T11 2.0

It has been stated that C9-T11 2.0 could be substituted with less expensive CLA and phosphatidylserine supplements. Phosphatidylserine can be found anywhere from $9 to about $40, while CLA can be purchased for about $15 to $25. These can also be found locally, which avoids shipping charges and delays.

Bottom Line

C9-T11 is a supplement which contains CLA and phosphatidylserine. The amount of phosphatidylserine is below what most studies have found to be effect for lowering cortisol.
