These drugs aren't dangerous, and for those that seek them it's often life saving. This isn't "illegal prescriptions" like oxy for a high that fuels drug trade. Seriously, there is no gain for humanity by making life MORE difficult for trans folk. Especially in the UK where the wait list for a prescription is literally YEARS long.
It's super duper disengenerous to call these illegal drug. Their medicine for people with gender dysphoria, and further restricting their access to it is nothing short of cruelty.
