I would tell your platypus to go with the d-limo, then salt with vinegar. Repeat extensively, then purify the final product with multiple anhydrous, ice-cold MEK washes.
The oil tek is still in its infancy phase for mescaline, and has not been extensively tested. AFAIK, only yatiqiri's SWIM has attempted it, and the results seemed a little disappointing...
69ron's d-limo tek is pure gold, but only if one performs the final MEK wash. If the MEK wash is ignored or fouled up, the results are often inconsistent and disappointing. SWIM has never had anything but great results with this tek...
