Six Star Testosterone Booster Review

Six Star Testosterone Booster is, as the name implies, Six Star Pro Nutrition’s Testosterone Booster. The formula is extremely simple, with only three ingredients: Rhodiola, Gingko, and Boron…

Six Star Pro Nutrition Testosterone Booster



Rhodiola Rosea has a long history of use as an adaptogen, meaning it can decrease the body’s sensitivity to stressful situations, physical or mental. Preliminary studies in animals have shown that Rhodiola Rosea produces anabolic effects similar to low dose testosterone treatment.

One human trial, to determine a possible role in erectile dysfunction, found that subjects who consumed 150-200mg Rhodiola Rosea daily for three months experienced heightened sexual function. Whether this was a direct result of increased testosterone is unknown, but given the preliminary support from the animal studies, it is certainly a possibility.

Six Star Testosterone Booster contains 386mg of Rhodiola Rosea extract per serving.


Gingko, while commonly used as a nootropic, has been under investigation for a variety of applications, including as a potential alternative treatment for erectile dysfunction. It has long been used in alternative medicine for ED because of its alleged ability to enhance blood flow via increasing nitric oxide.

However, a 2011 study found elevated dopamine levels in rats that were given Gingko extract. Dopamine has been identified as a major influence on sexual response, and this offers an alternative mechanism of action by which Gingko may improve erectile function.

However, the evidence is far from conclusive, and a good deal of research would be needed before drawing any conclusions about Gingko as a treatment for erectile dysfunction.

Six Star Testosterone Booster contains 2.7mg of Gingko Biloba extract, an extremely negligible dose.


A 2011 study, published in the “Journal of Trace Minerals in Medicine and Biology”, found that boron supplementation (11.6 mg daily) over a one week period was found to increase Testosterone to a statistically significant degree (28%).

An earlier study (1993), found that daily supplementation with 2.5 mg of boron over a 7 week period failed to increase testosterone levels.

The obvious reason for the discrepancy is that the 2011 study used 4-5 times as much boron as the earlier study, but more research would be needed to confirm that.

Six Star lists the dose of Boron in the formula at 5mg of elemental Boron per serving.


Six Star Testosterone Booster actually doesn’t contain any ingredients which will outright boost Testosterone beyond normal.  There are far superior Testosterone Boosters/Optimizers out there…
