How do you dial in the RATIO (not the quantity) for a mix

[BrokenPiston]

The ratio can of course affect quantity, as can the concentration of the mix. I'm looking at a product sheet from one compounding pharmacy and my god the number of different mixes even for just TriMix is astounding. How does anybody go about figuring out which to get without trial and error or just getting a "standard" ratio mix and running with it? The stuff is expensive enough and I'm not aware of any pharmacy that has mini "sampler" vials (though that'd be a cool thing if so).

I visited my urologist and he injected 10 units of the standard 30-1-10 mix. I got about 40% erect. I got a script for it and experimented a little bit. 18-20 units got me 80% of the way there and with stimulation from foreplay I was good to go.
If oral medicine still kind of works but not as well as you need it to I'd start with a small amount of the lowest prescription of Tri-Mix or Bi-Mix.
ALSO: DO NOT START INJECTIONS WITHOUT A BOTTLE PHENYLEPHRINE!!! I can't believe how many guys still have to make trips to the emergency room after trying injections for the first time because they over did it.
With you having Peyronies injections may make this worse.
