Selfhacked doesn't vet or validate very well. Tons of information that makes you feel like everything under the sun is going to solve your issues, but without the extreme evidence required to prove it.

It's supposed to provide ideas to check yourself by reading the papers, googling for more and mindfully trying yourself (considering counterindications also listed) to find out if it works for you (get your own empirical evidence). This is valuable for specific kind of pracrically-scientifically-minded people. Those who prefer a ready solution meant to be fool-proof (although it rarely is) and off-load research, experimentation and responsibility to someone else should really stick with a doctor. Googling medical advices and expecting them to be correct (for you in particular) by default is a nonsensical approach, sadly many people seem practicing it.

I went in with high hopes of quality resources but I was met with one of those guide selling sites. I never knew exactly what it was trying to sell me either.

I don't care about the guides they sell (they have to sell something to those interested to make their living and I don't mind). I just type a substance name in the search field and get a list of good and bad things it may do with links to relevant papers. Or I type a condition name and get a list of substances which may have relevant effects.

The fact they are sincere as science makes me feel very sympathetic: they don't hesitate to mention nicotine (don't confuse it with cigarettes, it's about pure nicotine which may be delivered by many ways while cigarettes also load your lungs with tar and heavy metals) is great for weight loss and many other things. I don't really like the idea of using nicotine (because I mind physiological addiction) but I'm pleased they let me know and think for myself. They also don't hesitate to mention beneficial effect of some illegal substances.
