Can you inject bimix on the side of the curved penis? I got the curve a few months ago and have only injected on the opposite side...

hi all, newbie here...I've tried trimix 3 times, 1st one a fail......next one was good, 3rd one was ok for penetration but 'bendable'; I use .21 amount; it last approx. 1 hour then subsides completely after 2 hours...........if I go to .25 amount with it be 'harder'?
