Actually Tramadol and Buprenorphine (Subutex/Suboxone) are great together; Tramadol is one of the very few opioids that is not blocked by Buprenorphine and still binds to opioid receptors and combining the two has a synergistic effect and a high that lasts for at least 8-12 hrs IF you are opiate/opioid tolerant, if you have no tolerance to opiates/opioids then you'll probably get high for at least 2 days as Buprenorphine has an extremely long half-life and Tramadol has a relatively long half-life. The combination is quite euphoric and pleasurable and can be a little 'speedy' at the beginning but then it slowly smooths itself out and eventually you'll be nodding your ass off.
As for doses, I'd say for a non-tolerant person 0.2mg-0.5mg of Buprenorphine depending whether the consumer is opioid-naive along with 50mg-150mg of Tramadol; A tolerant and experienced opiate/opioid user should use around 2mg-8mg of Buprenorphine and 200mg-600mg (maybe even more if you are experienced with Tramadol as it is a very unique opioid).
You should use a low dose of benzodiazepines if you're planning to do this though seeing as both Tramadol and Buprenorphine lower the siezure threshold; I'd recommend a long-acting benzo like Clonazepam (klonopin) or Diazepam (Valium) seeing as they both have long half-lives.
If you're planning to get really fucked up then smoke a few bowls on top of that and you'll be in heaven.
IME this is true. Many say that you should dose the tramadol after the bupe, because of the blockade effect of both bupe and naloxone (but the naloxone is proven to basically be inactive, so don't even both taking it into consideration IMO. Buprenorphine has a much higher affinity for the opi receptors than naloxone) and the fact that bupe is a potent partial-agonist, but the best synergy I ever got outta' tramadol and bupe was back when I was still attending a local community college and took about 350mg of tramadol + 50mg diazepam and a couple hours later took 2mg of Suboxone (the "less is more" statement about buprenorphine is most certainly true dose no more than 2mg, but since sublingual BA isn't 100%, you can take 4mg sublingually and it = 2mg bupe; I find many people are happy with doses <2mg). I was nodding face! I never thought the synergy between these very mildly euphoric drugs, and tramadol- being such a weak opioid, could reach such a significant opioid-euphoria. If I hadn't known any better, I would've assumed I had been on a high dose of morphine or another potent, sedating mu-opioid full agonist!Actually Tramadol and Buprenorphine (Subutex/Suboxone) are great together; Tramadol is one of the very few opioids that is not blocked by Buprenorphine and still binds to opioid receptors and combining the two has a synergistic effect and a high that lasts for at least 8-12 hrs [or more considering buprenorphine has a half-life of 36 hrs]...
