Since summertime I've been having issues with my front left delt and pain in that area... So much so I haven't been able to bench much and OHP gets aggravated too.

When I'm cruising it's 200mg test and 125mg nandrolone, and I notice the next morning after injection my left delt will be absolutely killing me. (injected elsewhere)

Due to such I wanted to run my own little experiment and noticed if I inject nandrolone only it does not do so, but it is post testosterone injection that results in the inflammatory response (and it's really noticeable). (I also don't run an AI).

I've been running the above numbers for years with no problems until earlier this year, I think I'm going to try out daily micro injections (not changing weekly totals) and see if maybe it's just the sudden onset too much in one go. Or... it possibly could be a reaction to the carrier oil? (I'm only hypothesizing here as I honestly don't know).

I did used to frequently inject my delts in the past, but once I started having this issue I switched to other sites and that didn't resolve the issue.

Just thought I'd make this post because I'm trying to rack my brain and figure out what the cause is and what changes I might need to make.
