What are the undesirable side effects of Testek ?

Testek naturally increases testosterone levels. Since everyone has different sensitivity to an increase in this hormone, reactions to this supplementation can vary. This can lead to mood changes, sleep problems, and acne. However, these side effects remain theoretical for any increase in testosterone.

Most products do not cause side effects and are very well tolerated. There are always possibilities of allergies or digestive issues with any food product, but these are quite rare.
