I buy it from Costco. Cheaper than Walmart/Sams. I feed 23 pills 2x a day. I copied the dosage from a different forum.
"6.6 mg/kg, PO, q 8 h.
Roughly translated, 1200 lbs = 545.5 kg, so 3600mg/dose.
I use the 150mg pills, so that would be 24/meal. If you can't do three times a day, there are people that see positive results with twice daily administration."
