Most of what I've tried hasn't worked. That's the honest version of decades of self-experimentation. But some of it has, and the difference between the two is usually in the quality of the evidence behind the substance before you start.

St John's Wort interacts badly with SSRIs and a long list of other prescription medicines. It's also sold freely in every health food shop with no warning label. This is a gap in consumer protection that most supplement sources don't mention. #supplements #herbalmedicine

Ashwagandha and cortisol keep turning up together in the research. The connection makes sense: when your stress system is running hot everything else gets deprioritised. Sex included. That's not folklore, it's biology. #wellness

Western medicine has done well at solving the mechanics of sexual function. What it has almost entirely ignored is desire — the wanting, the appetite, the subjective experience of feeling sexual. Those are not the same problem. #desire

Herbal supplements don't have to prove they work before going on sale. Prescription drugs do. That gap between those two sentences is where a lot of people get misled and occasionally hurt. #supplements

Walk into any pharmacy and you'll find products for erectile dysfunction, vaginal dryness, and contraception. Nothing for desire itself. That gap is what I've spent decades investigating. #sexualhealth

Saffron keeps showing up in the libido research and it's one of the more credible stories in a field full of wishful thinking. Three clinical trials, consistent results, a plausible mechanism. Worth knowing about. #libido

A teenager reads one article in a science magazine and spends the next fifty years testing supplements on himself. That's the origin story behind pascalacy.com — and it turns out some of them actually work. #sexualhealth #libido
