Pro Nutrition Six Star Testosterone Booster

Verdict: Definitely Not Recommended

Reason: Ingredient formula is incredibly weak with no scientific data to back it up. The product does not  include the following ingredients which are scientifically proven to work:

  • D-Aspartic Acid
  • Vitamins D and B6
  • Magnesium
  • Zinc

This product lacks any real substance and I would be very surprised to see any results based on the ingredient list.

I personally recommend Testogen – read my review.

Six Star Testosterone Booster


Six star test booster does not include my recommended ingredients, especially D-aspartic acid which is a non-negotiable and scientifically proven to be extremely effective at promoting testosterone production.

Boron Citrate 

Boron is used in quite a few boosters however there is very little proof that it is effective. Also it has been reported to be toxic in large doses.


Six star supplements contain 45mg of calcium thus meeting the body’s calcium needs. Other than strengthening bones, calcium can help in building muscles – although will only have a mild impact.

Anti Catabolic Complex

This consists of Rhodiola and Gingkgo extract. Unfortunately there is no real proof of either of these ingredients being very effective.

Results from Users

Overall, the results and reviews for this product were mixed. You can read some reviews on the Amazon listing.

Six Star Testosterone Booster Side Effects

During my research I noticed a few side effects associated with this testosterone supplement that include headaches, acne and insomnia. Almost 5% of all users complained about this same issue.  However I stumbled on a solution on one of the bodybuilding forums where a user suggested that it is due to lack of water and people should increase their water intake to at least 120oz a day. Whether this is the case or not I can not safely say.

A lot of users have experienced terrible acne breakouts using this product.


To buy Six Star testosterone booster, Amazon seemed to offer a fair deal provided that a user bought in bulk.

To be honest it doesn’t really matter though because this product can not work based on its ingredients, I guess that’s why it’s so cheap.

Which Booster Do I Recommend?

For most guys I recommend Testogen.

If you are over 50 and looking to offset the symptoms of low t levels I recommend Prime Male.
