I am getting ready to make some tren from Fina, and none of the instructions I have read state that one should vent the Tren ampule when baking in oven at 250 degrees. Do you or don’t you vent with needle?
I would think not, as the BA/BB would easily evaporate. Also, needles have that damned plastic doo-whicky on the end where you normally attach to a syringe. Would think that would melt.
Getting ready to make a batch using Methyl Alcohol to make Tren powder from Fina. Will let you know how it goes.
