Dear Wasim Miyaan, Hi I appreciate your concern for the safety of Nandrolone as energy booster. Anabolic steroids like Nandrolone are most oftenly misused for the purpose of enhancing the muscle mass or performance on the sports field. Such type of use is not safe as it may result in testicular atrophy, decreased spermatogenesis, impotence, decreased libido, gynecomastia, & prostatic enlargement in adult males. Continue attending gym but without anabolic steroids, instead take a healthy balanced diet rich in first class proteins such as meat, poultry, fish, and eggs beside fruits and vegetables. Avoid smoking. Hope to have answered your query. Good luck.
