I have been using Bimix standard concentration of 30mg/1mg for around 2 months now. I started small with .1ml, then worked my way up to .5ml/50 units in a diabetes syringe. Until I got to .5ml, I didn't get any real results. At .3ml, I got puffy, at .4ml I got semi erect, not useable. .5ml give me an erection that comes on in 20 minutes or so and lasts for around 2 hrs. I have tried to go back down in the dose a little at a time, but it takes the full .5ml dose to work for me. I am hopeful that as I regain function, I will be able to cut back on the dose size, to eventually reach the zero level. Now, I am 5 months post surgery, using Viagra 50 mg and a pump daily since Day 10, and am having absolutely no response to any of it. The Viagra does nothing, the pump does its job, but the blood flows back out as quickly as it is pulled in. I think thats the reason I need so much Bimix, compared to others here. I have no veinous valve control yet, so it takes more Bimix to do the deed. When using rings and the pump, rings don't help, unless they are so small they completely cut off all blood inflow and outflow. The Bimix works great, keeps the veinous valves closed after filling the penis and it doesn't hurt in any way. Injection technique is a big part of successful use of it. I switched from a 1/2 long needle to 5/16 long, as the 1/2 inch seemed to get into the cartlidge or whatever that is in the middle of the penis, seperating the 2 cavernous areas. Each time it did, it hurt like heck and I couldn't inject the dose, had to pull back on the needle a little way to get the injection done. A few times I have injected into the rolled and bunched up skin that is much more present since the surgical shorting I got for free////lol. Lately, I have been using the pump to pre-plump before injecting, giving myself a larger area to hit when I inject. That seems to work best for me.
It may be that you do need to increase the dose, maybe a .05 or .1 ml at a time, or reexamine your injecting technique to make sure you are hitting the right area with the full amount of the drug.
