This entire process that we go through is due to excess vasodilation caused by stress that causes low serotonin, sedentary lifestyle that causes low dopamine and endorphins and muscle weakness (genetic) that makes us more susceptible to pain and tension. As long as this cycle is not broken, studying receptors and drugs wont help.

Actually nothing you have said here makes much sense, and it's not relevant to the topic being discussed.

Predisone is one of the few drugs that helps me.  At a high enough dose, I don't have any symptoms.  I was just wondering, is there any explanation of prednisones' efficacy (for my particular biology) that would serve to substantiate this theory?

Thanks, BB88, I assume the higher dose anti-POIS efficacy has a significant downside of side effects for you?

10 years of significant POIS-reduction, treatment consisting of daily (365 days/year) testosterone patches.

TRT must be checked out carefully with your doctor due to fertility, cardiac and other risks.

40+ years of severe 4-days-POIS, married, raised a family, started/ran a business

One possible explanation:
High-dose corticosteroid therapy increases plasma SIRT-1.
https://academic.oup.com/ndt/article/36/Supplement_1/gfab078.0020/6288899?login=true

SIRT-1 is a co-activator of PGC-1a and their interaction positively influences mitochondrial biogenesis.

The cause is probably the senescence of sexual organs and resultant inducible SASP, which also acts as a kind of non-diabetic metabolic syndrome.

@demografx - I actually haven't had a problem with side effects from Prednisone thankfully!  I've found that if I maintain my vitamin D levels, I don't experience side effects until I get into really high doses of prednisone.  Lately, I've taken around ~7.5mg with no side effects.


@Progecitor - Thanks for sharing!  The doses discussed in that research are way, way higher than what I take.  I wonder if the SIRT-1 increase with my dose schedule would be enough to account for muscarinic effects.
