making testosterone without magnetic stirrer

Idk how you guys do it, but my buddy who runs his own lab told me to put the solvents and powder in a beaker FIRST; let them break down the powder into a liquid; then heat that up in the pan; and finally, add oil in the beaker LAST, while it is in the pan.

At first it may seem the solvents alone are not enough to liquify the raws, but they are...

That's how I've done all my brews, and I have had zero crashes, no PIP, and it's very easy to have warm oil go through the syringe and filters.
I always only add 50% of the oil. Then heat and dissolve and top her off to the beaker lines last.
