The practitioner must stay in the formulation.
Formulation is not a manufacturing process; it is a considered decision. Every ingredient, every ratio, every process has a reason, rooted in classical pharmacology and in watching what actually works on actual bodies.
When that practitioner's attention leaves, the product becomes something else.
"I formulate every batch personally. Not because it's efficient, but because I believe a practitioner's attention changes what a product is."
