Hi Brightcloud,
I am currently taking three capsules a day a little before meals to maximize absorption. The most I have taken a day is four, the least two. To me even 4-6 weeks is a fair trial for PEAPure. I think you can only buy six boxes at a time dues to customs. I don't know how much the PEA has contributed to my well-being since I go to acupuncture also, but I do feel it has helped and I take pretty minimal medications (low dose nortriptyline) considering.
good luck!
