I respect completely everyone here who is open about it with their significant others. An honest life is enviable.
I'm with all the other guys though. While she knows I'm on TRT, she doesn't really understand what it means so a box of needles and vials is just part of the deal. I keep my gear for runs in another spot and preload pins so to her, its just a box of medical supplies that I need to take every few days. If she ever got really nosy it wouldn't take much for her to wonder why my TRT dose is 6cc's a week
OP... it's been 1.5 months.... and you're offering her an easy way to destroy your life.
Best of luck,
