How much is a good microdose of PE?

Hey guys so I have took shrooms twice now well 3 times really but the first time they really hit i took about 1.2 of penis envy and it blew me away. Recently I got some more penis envy and I didnt use my scale I just bit a couple peices off and it hit hard. I want to take a small microdose but not trip to hard. What do yall recommend? Maybe .2 ish or 3?
