no offense man but what does mean i will sell sudo when i will learned bout chemistry, wow you look like me when i was doing the armchair cook at the underground hive or at the wetdreams/zonez years.
first how would you collect the precursors? if you are in EU u know like me that since there is no major dealing of d-meth aside czech republic and some thailand community who use and sell shaboo and the pink yaba tablets only to thai people.
also the rc scene here in eu was huge and im talking not nowadays but from the inception of the uk scene, the uk ban and back then the scene was more obscure, i mean i was almost killed from bromodragonfly which at the time i used for novelties shop because before the china ban here in EU there were internet shops from poland and email vendors like till.i.come which used to sell pse extracted from pills, but i mean, you cannot make money over pse manufacturing.
also remember that most methods you find are not usable anymore especially in the us.
the best are the white 60 or the 120 mg, personally i only use the 60 mg pse 2,5 cetirizine which you can pull good yeilds or the 120 with povidone.
also remember that the write ups from the legendary guys here who share this work of god is always the ending process of a long way full of failed experiments and trials.
and also the minimun pse to have a good newbie cook is in my experience 8/10 grams of pse fb,
