How did you feel the neurotoxicity? Short-term effects or even long-term effects from excessive use are not tantamount to neurotoxicity. I bet long-term post-use syndromes from 4-MMC similar to those happening from excessive use of MDMA happen, but are they really all due to actual neurotoxicity? I doubt it, I've had my share of excessive use of 4-MMC and 3-MMC for half a year maybe, and I had some side effects lingering for a few months like low mood (couldn't really tell that apart from my usual low mood though), feeling tired, unmotivated, and numbing in extremities, but it all passed. I'm not saying these drugs don't affect your brain long-term, but I don't think it's neurotoxicity.
Anyway, nobody can actually give you the structure of 5F-PVP or 9F-PVP, they are not chemical names according to any standardized nomenclature, they could be anything. With 4-MMC for instance it is at least clear that 4-methylmethcathinone is meant (which doesn't change the fact anyone could sell anything as 4-MMC), with 5F-PVP it's impossible to tell. I suppose it might be a trick to postpone banning those compounds, certain countries ban substances by their chemical names, e.g. in Poland there was an update of the banned substances list some time ago and they basically put there anything they could find on the internet, including compounds from Wikipedia, I guess, that never made it to the market, they can't ban 5F-PVP though that way. I suppose a similar system may function in a lot of countries that don't have analogue acts.
