Trimix. Please help to find it

[JackBlack]

Hello everyone I’m living in Vietnam and can’t find any Trimix here. I know a place in Thailand but they don’t provide any prescription so I’m a bit afraid I’m gonna have troubles when try to leave Thailand or enter Vietnam.
Please share your experience if you have any tips how to find Trimix in Vietnam or any near country and be able to get back without risks.
I need 1-2 vial every 6 months.

I also tried to order it from IndiaMart but package stuck in customs forever.

Please help, it is extremely crucial for me, I think you understand. If you want you can contact me by email: 0001byte@gmail.com
