I happened to come across about 50 pills of Tramadol (for free!) Anyways, I've been searching around for the active ingrediants in it, and I'm kind of confused. From the different websites that I've been to (Erowid, and various pharmacology sites, also searched this forum and found some threads about it) It seems like some tramadol contains acetaminphin. I'm trying to figure out if the ones I have do, they have the numbers 58 on one side and the numbers 93 on the other. I searched wiht google to no avail, just wondering if anyone knows anything about it? I'm pretty sure they have 50 mg of tramadol hydrocholoride in them.
