Trimix- Gel or Injection

I know that the injections are more fool proof than the gel but I was wondering if anyone has had positive responses from the gel. Is it worth giving it a try before making the leap to the injections. I am lucky enough to get fairly good erections but not as firm as I would like. Suggestions. I had radiation 5 years ago and still function well. I just want to go to the next level. Thanks!

Why not try the gel and see how effective it is first? If you can get the gel and are happy with the results, great! If not, you can always switch to the injection.
