Just came across this by a guy called Oleksandr Savsunenko:

Not sure if it’s particularly relevant to blood clotting but it deals with blood markers in general after taking 3 gram of fisetin for 6 days, so any scientists here might be able to make sense if it all.
I’ve quoted it in full below:
“I am sharing a story of self-experiment with fisetin — a potential health and longevity-boosting drug, belonging to a novel class of senolytic compounds.
Background
I am an enthusiast “biohacker” (whatever this means). I am doing regular health check-ups and bloodwork at least two times a year, monitoring critical health and ageing biomarkers, as well as trying various medical interventions to boost my mental and physical state. Also, I can “almost” be considered a professional, as I am M.Sc. biochemist and a PhD in macromolecular chemistry (this means I try not to do stupid things).
Senotylics have been taking anti-ageing community by storm. Senescence-based theory of ageing is currently considered as one of the most promising approaches to fight some critical manifestations of ageing.
Long story short. There’s a normal ageing process that every cell goes thought. They divide, they live, they die. But, not all of them — sometimes natural mechanism of removing old cells (apoptosis) gets broken and some cells get into the senescence phase. That’s a state of “limbo” — cell continues to live, consume resources, but produces no useful functions and pollutes surrounding space with chemical markers of age. Time goes by, body continues to accumulate those cells and impact becomes more and more visible — ageing.
The idea of senolytic therapy is pretty simple — let’s force those cells to die and remove them out of the body. This should really improve our health.
As I am writing this article Phase I of trials testing a most well-known combination of senolytics is in progress and even some very preliminary results made available.
Recent publication showed that a compound called “fisetin” has very pronounced senolytic properties. A high-dose acute intervention was shown to promote cleansing of senescent cells in mouses and human tissues.
And, by a great coincidence, fisetin is not an extremely expensive research chemical but rather a well-known flavonoid. And you can buy it online as a supplement.
Whaaaat? If this is such a great compound and it’s sold online, why nobody noticed any great health-promoting effects? One of the explanations is simple — the dosage. Researched used much higher doses of fisetin.
Anyway, I decided to give it a try.
The Experiment
I did a traditional bloodwork check-up based on Longevity Panel 1.4, containing major biomarkers a few weeks before I started the experiment.
This is a diagnostic panel developed by Russian longevity community, and I wasn’t able to find an English website to link you, guys. So, here’s my adjusted version of human blood biomarkers for longevity prediction and general health assessment.
Alanine transaminase
Vitamin B12
Albumine
Vitamin D (calciferol)
Folic acid
Ca 2+/Na 2+/K+/Cl-
Insulin
Creatinine
Uric acid
C-reactive proteins
T3 free / T4 free/ TSH
Ferritin
Lipid profile + cholesterol
HOMA-IR
HbA1
What did I expect from successful treatment? I had no idea, to be honest. Based on preliminary results from a similar experiment going on in Russian biohackers community I was looking for the dramatic change in cystatin C.
During my 6 day treatment, especially on the first and second day, I felt really strange — kind of light-headed and dizzy, also extremely thirsty and dehydrated (signs of dehydration are clearly seen even after two weeks when I did post-intervention checkup).
During the treatment, the most pronounced subjective effect was a change in skin condition. My wife noticed a fast and rapid change in my skin quality just in a few days. It became much firmer, hydrated (despite general dehydration) and smooth. I was very disappointed that I haven’t found a way to quantify this change. My next experiment will definitely include in-depth skin analysis using professional dermatologist equipment.
After two weeks from the last dose, I repeated my bloodwork, just to find that none of the biomarkers changed in a better direction and some just got slightly worse.
Conclusions
Other people experimenting with fisetin also didn't noticed any change in blood markers, as well as preliminary results from stage 1 clinical trial of another senolytics regiment (D+Q).
Potential explanations:
- it takes more time to develop changes in blood
- compound is ineffective in humans
- we should focus more on monitoring functional characteristics, like VO2 max, heart rate variability, pulse wave speed, etc.
- we need more people and more data”
