Customer Question

Hi, I am 55 years male with no history of medical problems. I exercise twice a week and I gave up smoking three years ago. Lately I was told about a supplement called "prime male" which is a natural testosterone booster. Higher levels of testosterone will lead to easier burning of fat result in high energy etc. I would like to know if this substance is safe to use and if it has any side effects. I would appreciate your reply as I am planning to order this product. The company's site is:

I am one of the medical experts.

Let me review the web page and the ingredient list of the supplement and then I will type an answer.

Expert:  Dr. D. Love replied 1 year ago.

I have reviewed the web page and have also searched the medical literature for other studies.

There is no good evidence that any dietary supplement can achieve significant elevation in testosterone levels. As pertains to this supplement, there is one study that they reference on their web page that shows that D-aspartic acid supplementation increases testosterone levels (see, but in reviewing the medical literature, there are no other studies that are able to replicate these findings. Instead, there is one study that showed no impact on gonadal hormone levels ( and a second study that showed a decrease in total and free testosterone (

Since there is limited data, trying the supplement is not without merit, but with the mixed evidence, it would be reasonable to approach this with an intent to monitor the effect to see if it works for you. To do that, it would be appropriate to measure your baseline level of total and free testosterone, and the repeat the levels after 2-4 weeks of taking the supplement. Once you see how it works for you, then you can make a more informed decision of whether to continue the use of the supplement.

If I can provide any additional information, please let me know.

Thanks for your reply! Do you see any danger in consuming the substance like side effects or any other possible health complications in the future? They suggesting a daily dose of 4 pils per day is this safe?
Expert:  Dr. D. Love replied 1 year ago.

3-6 grams of D-aspartic acid is what hass been studied, and it would take 4 pills to get to the upper range. None of the studies that looked at the short term effect of the supplement reported side effects (other than the one study that showed a lowering of testosterone and free testosterone. However, anything that increases testosterone would be expected to have side effects mediated by the testosterone, although the effect would vary from one person to another. Common possible side effects include acne, prostate enlargement, increased aggression or agitation, and an increased risk of heart disease.
