So you didn't think to tell us about this sub-q pin you were doing that came along with this horrible pip (that would last 3-4 days where you couldn't sleep) that you would get in your delts and glutes following each pin? Why wouldn't you inject a sub-q injection somehwere like your belly if you couldn't sleep on your side or back if this was the case. Something isn't adding up here
Edit: Your blood draws for TRT, how long after pinning do you have bloods taken?
I've had PIP from SQ shots, I've had PIP from IM shots. It's all the same. I don't inject oil on my belly because it looks awful. I can rotate a mL of oil SQ in my delts and V-glutes and I'll have an egg sized lump in each spot for 3 days. Inject that same mL into my belly and it I wind up with golf ball sized lumps on my abs, and I pin 3x week. At the gym and at home, it brings a lot more attention to something I'm not too keen on people knowing.
Blood draws on TRT are between 40 and 48 hours.
