What's in the capsules? Tiny beads?

@tisme My independent pharmacist gave me a bottle of empty capsules, a tiny funnel, and a little plastic tray with pinched corners. I empty one 37.5 mg capsule into a small clear glass bowl, press my fingers onto the granules and count them as I move them to a clear glass custard dish. I pour those onto the tray, and funnel them into an empty capsule, cap and repeat. I do this over a plate with a rim, to catch any escaping granules.
To start, I counted the number of granules inside three capsules--an average of 136. (The number may vary by manufacturer.) Then I calculated how many beads I needed to remove for the next lower dose. I'm doing reductions of no more than 10%.
My pharmacist assured me I could do it, and he was right. Good luck.
