I tried injecting Primo subq like I do with my TRT. It has not been pleasant. I experimented with .5ml 3 days ago and it has caused a painful lump still sitting there. Hopefully not an abscess. Going to just keep massaging, applying heat, and watch it for a week...hopefully goes away. Any other advice? I’ll be going back to IM, but curious if anyone else has ever tried Primo subq?
