Fisetin to Clear Senescent Cells
Following studies with mice that showed significant senolytic clearance of senescent cells following large doses of the readily available flavenoid supplement Fisetin, my wife and I (ages 79 and 84) decided to try it. We have just completed two sets of massive Fisetin doses.
We had Life Extension blood-work done in October before the start, and we will have more again next week to observe any changes. The first set of Fisetin doses was on October 22-25 with 800 mg/day for three days followed by 600 mg on the fourth day, for a total of 4 g. I didn't notice much in the way of effects. Perhaps some reduction of small aches and pains and some increase in energy and mental acuity.
For the second set of doses done November 22-26, since we experienced no negative side effects in the first set we decided to increase the dosage a bit and to add 10 mg of BioPerine, a supplement that is reputed to magnify the effects and potency of flavenoids. For five days starting on Thanksgiving we took 500 mg of Fisetin and 10 mg of BioPerine twice per day, for a total of 5 g of Fisetin.
This time. I did experience one negative side effect. A few months ago, about 2 AM in the morning I awoke from a deep sleep and experienced a severe episode of vertigo. I turned over in bed, and the the whole room seemed to tilt. Suddenly, I didn't know which way was up. I staggered to the bathroom and vomited. The symptoms tapered off and disappeared in a few days, but it was a very distributing experience.
On the 2nd day of our 2nd Fisetin series, I experience a recurrence of that vertigo in the middle of the night, not as bad as my initial experience but still rather disturbing. I tolerated this mild vertigo and continued the treatment. My wife had no similar symptoms, and after my last dose I experienced no further vertigo symptoms.
On the positive side, following the second set of dosages I did feel very well, and very sharp and alert. This past weekend I ran my Shetland Sheepdog Taliesin in an AKC Canine Agility Trial in Mt. Vernon, WA, and we did very well, qualifying in 7 runs out of 15 and getting various colored placement ribbons. I was feeling quite sharp, and I even invented a new dog-handling technique that fixed an ongoing problem we were having.
Next week we will do the blood-work again, and I'll report any changes.

New Fisetin Senolytic Session
It has been about 30 weeks since our last senolytic sessions, which were done last January. This morning my wife and I each took 10 mg of BioPerine, followed in 90 minutes by 2.00 grams of 98% pure Fisetin powder "dissolved" in olive oil. I put "dissolved" in quotes because I am not able to distinguish fully dissolved Fisetin from undissolved Fisetin in a colloidial suspension in the olive oil.
I put room-temperature olive oil in a 1 oz shot glass, then added 2 grams of yellow Fisetin powder, as measured on a digital scale with a precision of 0.01 grams. I stirred until I had a smooth liquid that looked a bit like French's mustard. It did not become clear, which may be an indication that lots of undissolved Fisetin granules were still suspended in the oil. The taste was acceptable, but not great. I noticed a slight burning sensation in my throat as I was swallowing the liquid. We used pieces of bread to soak up the mixture remaining in the glass, to make sure that we got it all.
That was three hours ago, and so far we have experienced no observable effects. We will repeat tomorrow, and then I plan to warm the olive oil in the microwave a bit before adding the Fisetin powder, to see if it dissolves better.

Unpleasant Side-Effects from a D+Q+F+P Session
Yesterday morning, my wife, daughter, and I did D+Q-based senolytic sessions. I took 10 mg of Bioperine, followed in 2 hours by 200 mg of Dasatinib, 2,400 mg of Quercetin and 1,700 mg of Fisetin. About 3 hours later I experienced a bout of mild diarrhea and a mild headache, but these passed and everything seemed fine.
In the late afternoon we all went to a Shakespeare-in-the-park performance of The Winter's Tale. Later that evening my daughter and I went to the cast party, at which I had three beers (she was driving). I went to bed about 10:30 PM feeling fine.
About 2:30 AM I awoke with intense abdominal cramps. I couldn't sleep for the rest of the night, so I got up and did computer things. At one point I became nauseated and vomited a bit of yellow fluid. The cramps were very intense and persisted until about 9 AM the next morning. Later, I took a long nap, and now I feel quite well and even a bit energetic.
I guess the moral here is, don't follow a senolytic session with beers. Live and learn.

98% pure Fisetin powder is available on Ebay in 10g ($22) or 25g ($49) quantities. The listing provides additional information, and suggests an EZ way to take it by just stirring the fisetin into a standard 1 oz. shot glass of warm water to form a milky yellow suspension, and then quickly gulping it down before the suspension has a chance to settle. You could say it has a 'chalky' taste, but it is basically tasteless. I've taken 500mg 'shots' this way. It's possible more than 500mg could be taken this way in a single shot, but I limit myself to 500mg. This is a very easy way to take it.
I personally do not like capsules (they seem to 'float' in my esophagus a while), but out of curiosity I made a few capsules containing approx. 500mg of the pure yellow powder. Using a size "00" empty capsule (empty wt. 110mg), I packed the big part of the capsule by pressing it down into the powder a few times until it wouldn't take any more, and then I put the smaller 'cap' part back on. The filled capsule weighed 610mg. Subtracting the 110mg wt. of the empty capsule, the content wt. was right around 500mg.
If doing this, keep in mind that the fisetin will dye fabrics a bright yellow, so avoid getting it on your clothing and wash your hands afterwards.

I've been lurking on this post and just signed up so that I could comment on the use of EGCG/Green Tea. My interest has been in the prevention of Alzheimer's and other dementias and depression. For those that do not know, EGCG is a powerful anti inflammatory that easily crosses the BBB. It acts on the same cytokines that present in the inflammatory process of brain issues mentioned above, notably TNFa, IL-6, and IL-1. So far it all seems to be of theoretical benefit.
My reasons for interest in this subject is that I have someone in my life with APOE4-4 and a long history of bipolar2, and intense depression. In my studies over a number of years I have come to accept that depression is the result of brain inflammation, which is becoming more widely accepted.
The practical application of this theory was tested one cold winter at about 3 am when the person in question decided to just walk away from life, not knowing where to go .. just trying to escape the depressive episode they were stuck in. I intervened about half a block away and returned them to the house with fair amount of resistance.
Maybe it sounds stupid but I had been studying the effects of EGCG on brain inflammation so I went to an all night grocery and bought up a bunch of green tea extract. It literally made a night and day difference in this person the same day.
Since then we have settled on 700 mg of decaf Green Tea extract from LEF 3 times a day. It's important to spread out the dose because EGCG has a short half life of about 5-6 hours. This event was years ago, BTW. My point? EGCG DOES work on an acute level in high doses. You do not need to theorize it's effects.
There is some speculation that EGCG can be tough on livers. We have not found that to be the case and early we did get liver enzymes tested a few times.
In your use with asynolitic treatment it's anti inflammatory effects alone might minimize the stress of the treatment and would likely improve the treatment IMO.
BTW, here's a link discussing the properties of green tea and EGCG in particular. It is much more than just an anti inflammatory but I cannot directly speak the many other benefits of it.

I will likely be trying out my own synolic testing with Q and F, and it will always include EGCG.
For those affected by APOE4 I do have a considerable amount of info to share which I am sure would be useful. When I get time I may search out any APOE4 posting on this site and contribute there. For now I am following this post and if this site allows it you could send me a message and I can share what I do know. I won't be polluting this fine post with that subject matter.

Hello, again. I take 500mg daily of pure theannine in capsule form., it is an important derivative of green tea. It has transformed the major stresses out of my life. I've taken it almost daily for 4 and a half years to help deal w a 4 1/2 year old child. It was recommended by my naturopathic physician. I know quite a few others who successfully use it also. Thankyou

I have been looking for a dasatinib mimic. In other words a Bcr-Abl tyrosine kinase inhibitor. If we can find this kind of substance then this substance could potentiate the combinations that we already experiment with. (fisetin, curcumin, quercetin and others) There are quite a few natural BCL-2 and BCL-XL inhibitors. Since dasatinib is a potential companion to fisetin I post this here.
Dasatinib is a BCR-ABL tyrosine kinase inhibitor and has, as far as I have seen, few similar natural substances. Until recently I have not found any interesting candidates that mimics dasatinib. What I have found out now is that chlorogenic acid might be a theoretical candidate. And I like to share this theory with the rest of you and those that are curious about finding a potential partner to fisetin + quercetin.
This indicates that chlorogenic acid has potential for being a dasatinib mimic. It is a long shot, but this is a far I have come. Future studies are of course needed but I have not found any other than the above mentioned study. The question is if we will see increased senolytic activity when Chlorogenic acid is combined with fisetin or quercetin or both? Or if it is combined with curcumin or theaflavins?
Since science (most likely) not will go in this direction it is up to us to do self-experiments. There are of course very many questions. How much chlorogenic acid is needed to reach therapeutic levels in plasma? Is it even possible to reach therapeutic levels? What do you think?
And does anybody here know of other Bcr-Abl tyrosine kinase inhibitors that are widely distributed substances.
And also, what relevance does this recent article in fight aging has on this theoretical discussion?
It is a long shot from the deletion of p38α in Neurons to triggering p38 mitogen-activated protein kinase-dependent apoptosis in chronic myelogenous leukemic cells.
Yes I know, This is a speculative theory but this is were we are right now. (Flying low and flying short, like the wright brothers did at kitty hawk).

I've done two courses of Fisetin treatment (I'm 50) along with my wife and aged mother, and we all saw fairly obvious symptoms of senolytic action. During the first round of treatment, I had a brief runny nose, my Mother had full-on cold symptoms, and my wife didn't notice any change. Also a scar/mole on my stomach started weeping from the edges. I noticed a week later that my stomach scar had shrunk greatly in size, and another scar on my shoulder that I had been keeping an eye on had completely disappeared. My occasional aching knee has stopped aching, and feels much looser. My mother and wife both had some skin tags that have now disappeared.
I see a lot of "fisetin does nothing" posts on the net, with people saying to try D+Q instead. I have a feeling people are using a sub-optimal protocol, sub-optimal fisetin, or don't have a great senescent cell burden, if they're seeing nothing.
The protocol I followed was to take 3g per day split over in 2 doses - one in the morning and one a couple hours later around noon, repeated 3 days in a row. To improve bioavailability, I took bioperene first, and unlike others here, I mixed the fisetin with cream. I seem to be one of those people that react badly to the salicylate in olive oil, and found the stuff would stir into table cream fairly easily, which covers the fat-soluble requirement. Two days prior to the protocol I dropped every supplement I was using, which at the time was just NR. I will say that none of us stopped drinking coffee.
The fisetin was 50% pure fisetin in bulk powder form. I used 6g of the product, to obtain a dose of 3g of fisetin. I mention this in case some of the other 50% product in the fisetin source (Cotinus Coggygria P.E.) has an impact on the effect.
Anyway, I tried this out mostly thanks to the information here. A big thanks from me for this great resource.
