Are we using WAY to low dose of fisetin? 10% vs 50% vs 98%

Hey guys. 

I just came to the conclusion that we might are using a way to low dose of fisetin. Alot of the sellers use 10% fisetin. This last year ive bought a 98% extract. But now when i started looking at better prices, its seems like alibaba got a 98 wich is yellow powder, and a 50% wich is brown yellow (the one i use now)

Wich is the powder ive used for a year now, marked as 98% pure fisetin ... wich means that if this pure fisetin, is only 50% ive only get half the dose.

I would guiess almost everyone who uses fisetin are getting the brown/yellow fisetin thats 50%. some might even use the 10%, and the side effects they get arent from removal of senessent cells but from the toxticity of the unpure plant.

So. 100g of 50 cost 80 dollar on alibaba. 100g 98 cost 160 dollars. 

I really like the 50% that i tought was pure but maby its better to spend the extra dollars and only use 1g per day instead of 2-3g of the half pure 50%.

The big question tho ... with all the studies about fisetin .. we dont even know what % they use. 

Are all these studies of fisetin made with pure 98% ? and the whole globe are using 10-50% pure and are under the illusion that we are getting the effect? 

And the side effects we get arent from cleaning the body of damaged cells but from plant toxticity. 

Toughts?
