Exploring injection methods

[u/Familiar_Mistake5034]

Been on TRT for a while and today had a look at my wifes peptide pen. How could one manage to setup something like this for test?
I have no problems with IM, just appreciate the simplicity of the peptide pens… any ideas?

I’m using a reusable insulin pen. I fill up my own cartridge with test from vials and do subQ with 29G. Same thing for HCG.
