I use .5ml bimix. I take Viagra generic nightly, usually and hour or so after the injection, but it has no effect on the injection itself. I have never used the autoinjector. Autoinjectors can be found at most large box pharmacies, like Walgreen's and CVC. Learning to and then manually injecting yourself won't be a big deal after the first time, I bet. Once you have a good result, after months of failure and impotence, then that injection will be looked forward to. lol
.2ml sounds like a good place to start. Up it to .3ml if it doesn't work. Bimix allows for larger amounts to adjust, as it isn't as powerful as the trimix or caverject. Not too close to the base, nor too close to the glans....Make sure you take time to study the various injection info links I gave you a couple weeks ago. Most of all, relax---it will be easy, and you will wonder what the nerves were all about after you've done it a couple times.
