parachute it... divide it into two 75mg parachutes each, and drop one, then when you start coming down, drop the other (approx 4 hours after the first one)
i just rub it all on my tongue and gums (not sure if theres a name for that). next time i do it i'm parachuting though
put it up your ass. most effective way and im not joking haha.
Also you will prolong the roll if you take 100 mg each to come up and split the remaining 100 mg about an hour later.
In reality your gf will probably need less and you will need slightly more.
