Is $600 for a 5-meo-dmt session reasonable?

A friend who goes to meditation retreats and has experimented with psychedelics. She recently met a couple at one of her meditation retreats that offer 5-meo. She recommends them and I am eager to try it. But $600 seems like a lot. But I don’t have anything to compare it too. It just seems like a lot. When I did Ketamine, it was $600 a session and that was in an office with a doctor. And while I trust her, she’s a rather trusting person that isn’t overly careful with her money. I often assume that people who are interested in psychedelics are going to be more ethical and moral (not just trying to make money), but there are all kinds and my own personal history tends to make me less trusting.

So I’d love to know from more experienced people whether $600 (US dollars) is within normal range. I don’t know how much synthetic 5-meo costs to obtain.

To some extent, I realize that it’s a matter of what it’s worth to each individual. And for a potentially life changing experience, a high price may be worth it.

Thanks in advance.

ETA: what is the going rate, if there is one? Also, I realize people need to make a living, I don’t expect people to just give it away. But since they portray themselves as wanting to help people become more aware, etc. and this is not their primary source of income.

Is it weird to ask? I feel weird asking since she thinks of them as friends and I don’t want to make her uncomfortable.

ETA2: I feel a little vulnerable because I am a bit desperate for healing. I just don’t want to feel taken advantage of. This isn’t just for personal experimentation. And I don’t have limitless funds. But I’m looking for some hope.

ETA3: He and his wife are traveling and are staying at my friend’s house for 2 nights. She asked if they would do the 5-Meo for me. So it would be at her house. (I usually do my psychedelic journeys at her house. She is my dad’s ex-wife. So she is like a mother figure) They mentioned a little breathwork. Instructions on how to take it. They will be there to watch. And I don’t think they took any formal course. He knew a friend that introduced him to it and taught him how to do it for others. He said he’s administered it to about 60 people so far.

I have been in therapy for over 2 decades. I’ve tried other therapies like Ketamine and ECT. I’ve done LSD, psilocybin and mdma therapeutically. I’m trying to get insurance to cover TMS. I am desperate for relief from my treatment resistant depression.

I am ultimately willing to pay for it because I am desperate and this opportunity is so convenient. But I’m scared of ruining the experience if I have these internal doubts about the integrity of the people administering it. And being so depressed, I have doubts about my ability to think things out rationally. Perhaps I am letting my distrustful part talk me out of it. I don’t know. I am just stressing about it now. I am probably overthinking everything. And due to my depression and anxiety, it is not easy for me to just go to another country where it’s cheaper. It is hard enough just getting through each day. So there’s a scarcity component. I don’t know when I’ll have this kind of opportunity again.

Eta4: I don’t think this will cure my depression. They are not claiming it will and they are not therapists. It’s just something they offer. I am just open to trying that may help in the healing journey and I’ve heard it can help.

I appreciate everyone’s feedback.
