3-FPM, vs , 4F-MPH, 2-FMA

Which is the least and most toxic? 
 

gives you the most focus?

Toxicity is not well known as these are RC's.

That being said, 2-FMA wins in the focus department. 4mph is nice but can be edgy to some folks. 3fpm ive used but remember virtually nothing about it besides the holy burn when trying to insufflate.

@7ohmbro If you throw let's say 3-FA, 3-FMA and 2-FA into the mix, would 2-FMA still be the best one for focus? And most euphoric out of the bunch?

I have no experience with any of those three so I cannot say.
