Have you tried this:
iPT-141 10mg
The name on RUI's site is different it's actually called PT-141, it works awesome.
I had the same results with liquid via, cialis etc. since i got a sample from my urologist for viagra and I felt it way different than the liquid. None of them seem to work on me but, PT-141 does work really well. I dose it a little higher at first I did 3mg and i was getting hard ons all day and night and just randomly like driving my car or something, or even getting a massage even though normally I don't get hard during a massage but, on that stuff I was popping out and I was getting a legit massage with draping, it wasn't a massage parlor lol so there was no arousal, or anything and it was still working.
I still take a higher dose like 2.5mg and it takes a couple hours to kick in but, then it's good for like the whole day basically, at least for me.
That stuff works differently then cialis, viagra etc. I don't remember exactly I don't want to go through finding the technical info but, viagra, cialis etc. are pde5 inhibitors which try to pump more blood to get you hard but, pt-141 (chemical name: Bremelanotide) works on your CNS system.
With viagra etc. you have to receive direct simulation for it to work, you're not going just get a hard on out of nowhere but, with PT-141 like I said I was getting hard ons just laying down trying to watch tv, or driving, that was when I did the 3mg though. Though it wasn't like I was walking around in public with a boner lol (not like my experience with trimix haha).
My urologist had given me samples of viagra and instead of asking her to prescribe it (didn't work that well for me but, could see an improvement over the liquid stuff on research sites). I decided I'd just stick with pt-141 since it worked way better.
