Help for taking T on secret?

A friend from Spain asked for my help so I come here as he doesn't have a reddit account (i asked permission to post this so dw) if it they could do it without the people he lives with noticing (they are his tutors, something like that, some either are transphobic/homophobic or just ignorant, he doesn't how could react but he said that they could react in ways that would put him into stress plus more depressive than he already is. He is unsure if he could get kicked, he was close to, a few times mind you, for another unrelated reasons, but nothing happened in the end so it's not very clear), they know the risks so that's why he wants to make sure if there's a chance they can get away with it. He's aware it's a very bad idea, but they're suffering a lot bc of dysphoria and other problems in their life. They're an adult, still unemployed. They're kind of wary of doctors bc what if they snitch out? What if they are transphobic? Is there any kind of red flag? Or what if the pharmacist or doctor accidentally tells someone? Or what if somehow these people can see personal info of them? I don't know how it works in Spain so if someone knows pls tell me.

For all these things that could go wrong he's reluctant to do it and also, because going through male puberty with the people who lives with, knowing how it goes... I can understand why it can get uh weird/awkward, he's worried it can trigger him new flashbacks (bc of CSA), is that possible? And before you ask, nope, he can't get professional help right now. He's indecisive from thinking of going high dose not low dose even if the most noticeable changes show bc of his high dysphoria and then thinking of going through the safest way which is low dose. He doesn't want these people to know he's trans and there's one of them who is very.. perspective? Like they can tell when there's something he's hiding (nothing illegal dw lol) or when he's feeling off (like depressed), they can tell, which, obviously, is another problem.. He has been on the closet for years, not being able to transition, so I can tell it's reaching to a point he's getting desperate.. Obviously he would stop when he can't no longer hide it if he keeps taking it.

Pls be kind to him, he's been through a lot
