Seems like (oral) androsterone is banned in my country. According to the gov’t website:
Epiandrosterone and 4-androsterone are drugs that are not authorized for use in Canada. Epiandrosterone is a metabolite of dehydroepiandrosterone (DHEA) and is a weak androgen, or male hormone. DHEA can cause higher than normal levels of male hormones in the body and could increase the risk of prostate, breast, ovarian and other hormone-sensitive cancers. Potential side effects include serious cardiovascular disease, and changes in fertility and sperm production. DHEA should be avoided by individuals with a history of abnormal heart rhythms, blood clotting disorders, liver disease, and those who are pregnant or breast-feeding.
4-androsterone is a metabolite of testosterone. Risks of using testosterone can include liver disease, heart disease and behavioural changes. Testosterone should not be used in men with prostate cancer.
Are these legit safety concerns?
