Hello Drewg39
Tried to reply directly to you, but here goes:
I use trimix, have been using it for the past yr and a half. I like the effect it has on me,my dick gets as hard as a brick and it's even harder to pull down, it will pop you in the face upon return. I suggest you might try this first before you inject, if you have a vacuum pump, pump your cock for about 15 minutes on and off, getting it hard in the cylinder and then releasing the pressure. Once you've done this let your cock get soft again and then take the head and pull down it like you want it to go to your knees, do this only until you feel your cock start to pull back, this is to give it extra stretch, then warm it between yr hands by rubbing it back and forth, this will increase the blood flow. Now you might think that this is a bit much, but if you haven't had a hard dick in a long while this should help you before you inject.
I don't know if you have a long dick, and that doesn't matter but then take your dick in yr hands and bend it sideways to the left or right depending on where you intend to inject. I usually inject on my right side, seems that the sweet spot and also I use B-D insulin syringes 31 gauge needle u-100. I fill mine to 10 units and inject, just push the needle in, if you feel resistance then you've got right spot in the cavernosa. Don't flinch as you inject you won't feel any pain. Then when you finish injecting start massaging your dick to spread the medicine around inside, you should start getting hard in less than 5 minutes. If you use a cock ring to constrict the blood , put it on as you start feeling your dick getting erect and then it for all of it's glory. If you have good kegel muscles in yr crotch try making your dick bounce up and down as you contract the muscles as if you wanted to pee and then stop.
I offer you this advice as it does work for me, my dick gets so hard I can go for about 3.5 hrs, letting the hardon subside and then stroking it back to life. I hope this will help you out, don't know if you're married or not, but feel free to reply if you like. I am a diabetic age 55 from NC and I am enjoying the after effects of using trimx.
