Nugenix Side Effects. What are the side effects of Nugenix testosterone boosters? The makers of the male supplement claim in their product FAQ section (at nugenix.com) that their research has not shown “any side effects associated with Nugenix”.
Now, just because the company makes this claim does not mean that there are indeed no Nugenix side effects that you have to watch out for.
The thing is, it is possible that they simply did not do good research.
