While testosterone gels can offer numerous benefits, potential side effects may accompany their use if they are misused. Common side effects of testosterone gels include skin reactions at the application site, such as itching, redness, or acne. If testosterone gels are abused, other side effects can arise, including an elevated risk of cardiovascular problems, fluid retention, mood changes, enlarged prostate, and decreased fertility. Adjust dosages when needed, or explore alternative options to effectively manage and minimize it.
