New to trimix, not sure what to expect.

[whatevery]

Decided to switch from 30mg Edex to trimix and am wondering if I made a mistake. Probably should've asked here first before switching but what's done is done.

Just got my first batch few days ago, haven't used it yet, put it in the refrigerator. It says 'inject 0.2ml 30 minutes before the activity. May increase dose by 0.1ml per injection to max of 1ml."

Looked through the posts here and couldn't find similar doses. I'm wondering what to expect. Will I get hard at all?

Also is it really 30 minutes before sex and it stays hard no more than 1-2 hours?

How long does it stay potent in the fridge? Should I move it to the freezer?

Should I go back to Edex?
