I'm having an issue since starting Opti blues. For context, I've been running 4IUs daily from another vendor for about 2 months with no issues. I had VERY slight CTS on my right hand but really only if I made exaggerated movements looking for it.
I then switched to Opti blacks, ran a kit of those for 20 days (5.08IUs per day) without issue.
4 days ago I switched to Opti blues, half a vial per day (5.43IUs per day). After 2 days I noticed my CTS was a bit worse. After 3 days it was noticeably worse to the point it woke me up. After 4 days it's so bad that I can't fully make a fist with my right hand.
So I'm completely stopping and waiting for it to completely go away, then I'll switch to Opti golds or my previous vendor (I have stock of both) at the same dose and see how they goes. If those are fine, I'll try the blues again and see if the issue returns.
Disclaimer: the day my CTS starting getting worse/the day I started blues was also the day I got really sick with what I assume to be the flu or covid. I want to mention this because I have no idea if an illness would exacerbate CTS. My whole body feels like death, I have chills and body aches, etc. so maybe it's making my CTS worse. ChatGPT says illnesses can make CTS worse, so hopefully that's all this is, but ChatGPT is wrong so often that it's hard to tell.
Also FWIW none of mine have been cloudy.
