Essentially you are trying to bring on gynecomastia. It is frequently a side effect of these drugs, some of which are OTC. Omeprazoloe and Cimetidine are two I know of.
Certain medications can promote breast growth. They interact with the natural levels of testosterone and estrogen, and upset the balance in some manner. Gynecomastia is a common consequence of estrogen treatment in patients with prostate cancer. Drugs that may cause gynecomastia include:
Hormones (androgens, anabolic steroids, estrogen agonists)
Antiandrogens or androgen-synthesis inhibitors
Antibiotics (isoniazid, ketoconazole, metronidazole)
Anti-ulcer medications such as
cimetidineCancer chemotherapeutics, especially alkylating agents
Cardiovascular drugs, such as captopril and digitoxin
Psychoactive agents, such as diazepam and tricyclic antidepressants
Recreational drugs, such as alcohol and marijuana
Penicillamine
Alcohol and drugs can cause gynecomastia by mimicking estrogen and stimulating androgen production. Steroids and other excess androgens are sometimes converted by the body into estrogens and consequently cause male breast problems.
