Bud: I also have a thin penis, so I use 5/16in. (8mm) needles (31 gauge.) I switched from 1/2in. years ago when I found that I could go right through a corpus. That isn't a problem (except for not getting the Trimix where it's supposed to go). Of course I could still use the 1/2in. length, just not ...

Agree with Old Guy, bldoink, and Txagq8 re auto injectors. I want to control the needle path. Your goal is to inject into a corpus cavernosum, but this commonly-used diagram shows ERECT corpora; the corpus you inject is much thinner. Picture a clock face - if you're trying to hit the right corpus on...

Get testosterone up to normal first! It's easy!

Welcome Bud. You're about to meet new friends. I've injected Trimix for seven years and am very satisfied with it. I find that manual injecting suits me better. The needles are made of very ductile steel, and so I don't worry about bending even 32 gauge, which are the thinnest available. I've bent a...

Rider: Nice to hear a success story!

I've used six-month-old Trimix kept unfrozen at 40F(4C) without any apparent deterioration. On a vacation I used Trimix kept at room temperature for five days with no diminishment of effect. I've never had to increase the dose to get the same result.

I've never frozen Trimix in seven years of use.

The last two-thirds of penis length, toward the head, has a few fluid connections between the two corpora. So I was told to squeeze or "pump" my length 6-8 times after injecting to get some Trimix into the other corpus. This helps to get a symmetric straight-ahead erection. Apparently not ...

Never Enough: I don't know the answer to your question. But my usual blood pressure is 120/80 and I've never noticed any low blood pressure effects from combining sildenafil with Trimix.

Your term "Anxiety" reminds me of the curious "Hard/Flaccid" problem, which has its own topic here on Frank Talk. Take a look there, and particularly at "Hard Flaccid - success story..." from Fed1981 9-3-20, and his original ED description: "27-year-old pump injury...

Agree with bldoink, but if you add Viagra or Cialis to injections, don't forget to take it an hour ahead of an injection, to get it absorbed completely (and stay out of "priapism territory"!).
