I also have had herniated discs in my neck. Bad. This is how I got into peptides and eventually steroids.
I started with bpc157 and then tb500 as well.
The initial relief was not huge. I did get like 90% better over time, but I did EVERYTHING I could reasonably believe might help.
If I could get back in time and Klow was available then, I would do that and I would do it for a very long time
Herniated discs are tough. As stated they will not unherniate the disc, but you will probably feel better and perhaps it will do something for you over a very long time period
