1/4g seems like a very low dose for pram, as I remember. I used to take it considerably higher, I just can't remember WHAT, since its a long time ago, and I actually do have a functional mnemonic impairment, and quite severe (for instance, I left a container of SOCl2 out for long enough that the quantity poured from the main reagent bottle almost entirely evaporated, and since I was masked up, I only noticed once my eyes started to sting like a bugger from the SO2/HCl fumes. Left a big jug of MeOH with the cap off, went to sort that out and in doing so, turned away from the thionyl, and it all hydrolysed by the time I remembered. Thankfully not a massive quantity and thankfully I most certainly did not leave the top off my actual bottle of the stuff and in doing so, thus waste precious reagents. Can get more SOCl2 any time I want some, without the slightest effort, but still, its getting to be one of my reagents that are flavour of the decade, lol. So versatile, lovely and quick in its reactions and breaks down to gaseous byproducts, for lovely simple workups. I'd hate for what I have to just have up and evaporated, and not just because the house would become uninhabitable, as would the lab section thereof, but because it is definitely one of my favourite reagents for many things at the moment)
What would folks call the upper ceiling for pramiracetam, per dose?
One thing I don't like about it though, is the way that it has that absolutely atrocious taste. Tastes nasty as all hell as I remember it.
