AutoInjectors/PenInjectors for Peptides

I see there are a number of very beneficial peptides and unfortunately it seems a lot of them require it to be injections.

I have tried to find oral version of them, but either it is hard to find or has low bioavailability.

So I am starting to consider injections, but I have terrible fear of needles.

I have seen there are some types needles like the Auto-injector or the Pen-injector. Is that suppose to make it less painful and easier?

Anyone used any of these and would I be able to put any medicine into it? Most of the ones sold seems to already contain insulin.

There was a company that for many years had remarkable peptides in the form of a patch, extremely efficient. Unfortunately the Federal Death Administration or Fraud, Deceit Administration (FDA), put them out of business completely.

Why? They are the watch dog for those who pay their bills, pharmaceutical companies or their competition.

Perhaps there are overseas patches that will provide this.
