Know your target alkaloid dose? Calculate how much powder you need to measure.
Formula: Target dose (mg) / Potency (%) x 100 = Powder needed (mg)
If you want 70mg of 7-OH from a 14% extract, you need: 70 / 0.14 = 500mg of powder.
This is the reverse of the potency calculator. Use this when you know how much active alkaloid you want and need to figure out how much powder to weigh out on your scale.
