The use of testosterone gel in combination with Viagra does not increase the effect of the blue pill. Testosterone gel is commonly prescribed to men with low libido, reduced hormone levels, and weak bone and muscle mass. According to experts, testosterone can also have a number of other benefits. A study found that in erectile dysfunction, testosterone therapy has a positive result. However, it is believed that combining testosterone therapy with Viagra does not increase the effect of the medication. 140 men between the ages of 40-70 took part in the study. Participants were prescribed 50-100 mg of Viagra. The tablets should be taken immediately before intercourse. After 6 weeks, the volunteers were randomly divided into two groups. The first group started using testosterone gel in combination with Viagra, and the other placebo gel again in combination with the medication for a period of 3 months. On the erectile dysfunction scale, 11-16 is considered moderate erectile dysfunction, 17-21 is mild to moderate dysfunction. The highest score for an erectile problem was 30.
