Hi there, Thanks for your query. The potential side effects of Androfil are as follows:- Fluid and electrolyte retention leading to swelling of feet/body; increased calcium in blood, impaired glucose tolerance; increased bone growth and skeletal weight; increase LDL (a harmful cholesterol); headache, depression and stomach bleeding. It can also cause sperm-formation suppression, painful sex, breasts enlargement, and accelerate growth of malignant prostate neoplasms. Since some of the above-mentioned side effects are serious, You should therefore use it ONLY under close supervision of your doctor. If you find my response helpful and informative, do not forget an “excellent” (5-star rating) to my answer, to ENCOURAGE ALL doctors- engaged in social service- to render sound advice to the FREE queries. Take care Dr. Rakesh Karanwal
