I have IV pharma grade Ketamine, and it works amazing for 2 things (3 if youre into the recreational side of it, personally im not)
1. It works GREAT for depression, im convinced that it CURED mine. I took it like 5 times and no more depression since then, and its been about a year since ive last taken it.
2. Its amazing for pain, you wont feel ANYTHING while you're on it. (at least at 25mg IM, the dose i took)
If you're trying to get ketamine infusions for depression, id definitely suggest doing it.
