Total nerd question about F and H

[Farmmaa]

I'm so confused that my head hurts this morning. Have been searching for real answers for two days and can't find two sources that say the same thing.
I am a complete nerd when it comes to knowing anything but the basics about street drugs.
I hope someone here can help.

So, since the darknet banned the use of the word fentanyl in ads … how does one know what it is they're buying ?
Pure H, or close to it, is listed as such but everything else is a crap shoot.

So... what is the difference between China White and Synthetic Heroin ?

A search brings up too many different opinions on whether they have F in them and which one has more or less

Help ??!!

We had a "tutorial" on H. I'm not sure it addresses your very good questions, though:

Thanks … I've read the threads listed and couldn't find anything regarding the different street names and what they actually contain
