Fisetin - misc

1.  Buying:  I  noticed this morning that a few products of Fisetin are either out-of-stock, or the price has increased considerably.  I'm esp interested in 500 mg caps, but I saw one offering 1,000 mg.  And one 50 gram in powder form.  Recommendations?

2.  Monitoring:  Personal feedback is super impt, but has anyone monitored some ez tools, e.g., blood pressure; Oximeter  readings; pulse, in addition to some blood work such as CR-P?  Preferably, history of 6 months, including days before, during, & after F + Q dosing?

3.  Including other info would also be helpful:  diet, exercise, supplements, any Rx drugs, etc.  Also age, weight, as well as either specific health issues, or at least a level of health issues.  Likely a 30 year-old, will have very different response than 70 y.o.  Also, one 70 y.o. in relatively good health, will not respond with same changes as someone with cancer, etc.

Possibly also helpful, would be health history / habits, over prior 5 - 20 years.  Someone whom spent youth drinking, and/or various drugs, likely have different senescent cells 30 years later.  Rx for SSRIs, statins, beta-blockers, etc., may also be of interest.
