Legal Risks of DIY T by Country
Key Difference from Estrogen
Testosterone is a controlled substance
Unlike estradiol, which is a non-controlled prescription medication in most countries, testosterone (and its esters) is classified as a controlled substance in the US, UK, EU, Canada, Australia, and many other jurisdictions. The legal risks for DIY testosterone are significantly higher than for DIY estrogen.

General Recommendation
