I have been using Trimix for 5 months and my current RX is double the concentration of the original so that I do not have to use as much which keeps the cost down per injection.
The RX is PAPV 30MG/PHENTLMN 1.5MG/PE-1 20MCG/ML
I use a 30ga 1/2" BD syringe that is in units, cc and ML. (100 units = 1cc or 1 ml) I am using .35cc/ml or 35 units to achieve a full erection that lasts about 11/2 to 2 hours.
The original RX was PAPV 30MG/PHENTLMN .5 MG/PE-1 10MCG/ML. I started at .30ml and increased it per URO instructions by .05ml each injection until I got to the .7ml that worked which took about 2 months.
I do not take any oral meds any more as the 100MG Viagra had no effect and gave me blue vision and a headache. I was using 25mg of Viagra in between injections per the URO advice but stopped about a month ago and have noticed no difference. I get 0 side effects from the Trimix and my wife and I love it. I used an auto injected at first but now I inject freestyle and have no pain at all.
I have found if I auto stimulate Willie before the injection it will plump up some and make it easier to find the veins and a good place for the injection site. I also do the constriction technique as described by others in this post.
I also got an indication from my URO last month that since I get 0 response from oral meds and due to the high amount of Trimix I need the long term prospects for my nerves healing and once again having natural erections is not very good.
