I have done five sessions all together, but I dont believe I have hit breakthrough on any of them. Low dose still feels great and different everytime. I dont know if it because of my updated custome machine extension or if it is the jell like forms burning/heating rate, but it seems less harsh to me. It comes out somewhat near 90% DMT and 10% NMT. Using A/B sry extraction using  pickling lime instead of lye. I dont feel comfortable with the dangers of lye myself, but to each there own.
