If a person who had never used opiates before IV'd 1mg of bupe they would barf their brains out for a day.

id start at the .25mg and if nothing than another .25mg. Since the original buprenorphine painkiller Temgesic comes in .2mg sublingual tabs. So I would think .25 would be ideal but anywhere between that and .5mg for a strong experience.
