Sinrex is a daily male enhancement supplement that claims to have a 2-in-1 action when it comes to male sexual performance. Firstly, it contains nutritional compounds which improve performance in the bedroom while also contributing to overall male health, and secondly it helps increase testosterone levels in the body.
After the age of 30, testosterone levels in the male body start to decline by about 1% per year on average. Low testosterone can have a number of negative effects on the body, including weight gain, lower energy, low libido, loss of muscle mass and depression.
