Dialing in trimix

I had my fourth shot today . Sorry guys if I’m being repetitive. Started 5 then 10 then 12 then 15 . Not getting what people are getting . Can I try 20 tomorrow that would be my 5th shot this week ? Is my injection technique right ? I stand , make my self semi flaccid or semi erect then shoot at 2 o’clock ? I might have hit a vein . I shoot just before the base . I was told to go up in 5 but didn’t want to incase of priapism.. is my mix weak ? Should I try 20 tomorrow ? I got Sudafed in hand . Those doses did do something today on my fourth shot I didn’t get the tingling sensation like the previous shots ?

Cheers guys sorry to hear annoying I made a few posts so far ..
