Dose - Oxycontin Beginner

[Psychonaut08]

SWIM has never taken anything from the opiod family before, and his friend should be able to sort out some oxycontin, but isn't sure about the dosage in the tablet e.t.c
when SWIM get's it he can tell through pill -id's hopefully, but he was wondering, he is around 90 KG, 6"2 and has NO tolerance to any opiod.
He has done MDMA/cocaine/acid e.t.c in high amounts, but is aware with the risks of oxycontin and high dosages, so he was wondering, and is sorry for posting as he is sure that there will be threads similar to this but used the search engine, but :

How should he take the OC, if it comes in a tablet form should he just swallow it with water, or crush it up and insufflate (he isn't much of a fan of snorting, and never plans on IV'ing or rectally administrating drugs).

How many MG should he take for a good first opiod experience, not anything too high and overwhelming but not an amount that will leave him feeling slightly stoned..

Thanks a lot
