I took plenty on menthol oil back in 2012/2013 winter. I think it upregulated endorphins or something because I experienced some pleasant effects but they were all short-lived. I don't think it's much of a plausible treatment to reguate the (kappa) opioid system to any major extent.
Well, not every treatment is going to work for everyone, or if they do, it has to be in combination with something else - diseases of the brain are often complicated, and hence needs complicated solutions.
I myself am currently on THREE f***ing ADHD-medications, with very different modes of action, and only now am I *kind of* feeling a half-decent effect.
Where you trying to treat some form of anhedonia, loss of pleasure, with kappa-agonism? I believe that is one of your issues, if I recall correctly?
I suppose you may simply be one of the lucky people whom doesn't have the same kind of overtly powerful homeostasis effect as the majority population - remember, using kappa agonists to down-regulate the Kappa-system is basically hedging your bet on the homeostasis effect that underlines the problem of tolerance to drugs - there ARE a number of people whom really can use both stimulants, gabaergics and hey... even opioid pain-killers for YEARS on end, without any appreciable tolerance - it's entirely possible that you're one of these types of people.
Unless you've taken a VERY powerful, and VERY selective Kappa-Antagonist, I don't think you can write off Kappa-modulation, even for yourself - and let's not forget that we're all different, neurodiversity is probably a very good thing evolutionarily, so different responses to different things is to be expected.

Crapppp, Stinkorninjor I need your wisdom!
See above... different strokes for different folks.
Let's not also forget that different issues can give similar symptoms, even though the underlying mechanisms, and hence the necessary treatment, is different.
That's what you're entire anhedonia -thread is all about, yes? You talk about how anhedonia can come from different mechanisms than the classic two or more types of depression and Schizophrenia, yes?
Just because kappa-antagonism doesn't work on some people doesn't mean that there's a number of people out there who will benefit.
