Hello and welcome!
We can't really help you with that as it's against the rules.
I've seen a few pain pills on the DN but they were always something stronger like oxyodone 80mg or methadone 40mg. Maybe you could find some tapentadol on there but to specifically find a 60mg codeine you are likely to need to know someone with a prescription. Have you ever tried kratom for pain? I used it for pain for years.
@Dribly , welcome to bluelight. But your first post is really a violation of rules (BLUA) as we do not allow drug sourcing or selling. If you don't delete the post (I don't know how you could edit it so it isn't sourcing) I believe that moderators of this subforum will and will inform you that this is not allowed.
Hope that you get medical care for your leg, as I know how painful a tear of the muscle is. Wish you speedy recovery, and that you will stick around - but sourcing is just not acceptable as Bluelight would not exist in a blink of an eye.
