I wish I had a good answer for you but I don't. I have never suffered from premature ejaculation. In fact I've always been a bit slow but prior to the RP I could always get off in a reasonable time. I didn't have ED prior to the RP and pills didn't work post RP so I can't with any confidence determi...

Don't get discouraged. It just sounds like you just missed on your second shot. Base your next shot on your first shot. I wouldn't bump up more than 5 units, so no more than 23.

I have no experience with bi-mix or tri-mix as the mono-mix works very well for me and is supposed to have a lower risk of ...

Follow your doctor's advice. You haven't mentioned anything about your history or cause of ED. You haven mentioned anything about your script like what mix and strength. Mono-mix, Bi-mix, Tri-mix, etc. I'm not a medical professional of any kind. Anything I post is based on my own experiences at best...
