One Thing I Noticed,
and When
Not a list of four. I take it for one reason, and one effect is all I can honestly report after 10+ years of daily use.
It Was Distracting
I took it for one reason: after 50, sexual interest drops off. Within the first couple of weeks my mind kept going there — enough that concentrating got harder. I assumed I was imagining it. I wasn't.
I Still Notice When I Stop
I never tracked any of it — no spreadsheet, no bloodwork. But the difference between taking it and not taking it is obvious to me, and that is the only reason I still buy it.
No Trial Has Tested This
No randomised trial has tested cistanche on its own for sexual function. The closest human work pairs it with ginkgo, and those authors cautioned the effect may be too small to matter. Mine is one man's experience, not evidence.
