The supplement bottles on the windowsill in my Pearl District apartment run oldest-to-newest from left to right. By the end of a busy test month, the row runs past the window frame. The rolling whiteboard behind the standing desk tracks which stacks are in active trial, which weeks have closed out, and what the current serving totals are. A digital kitchen scale sits next to the keyboard for the moments when a serving-size claim looks off enough to weigh.

Six years of this. It started with a checkup that flagged some numbers I hadn't been watching, a detour through everything fitness forums were recommending at the time, and a slow realization that the products with the slickest packaging almost always hid their actual dosing behind a proprietary blend. Forty-plus bottles later, the pattern is consistent enough that the testing process runs itself.

Two years in Southeast Asia came before any of this. A lot of that time was in markets and pharmacies where traditional remedies are as ordinary as anything in a Western chain. I paid too much for a tongkat ali extract in a Chiang Mai pharmacy and got a laugh from a Vietnamese friend whose grandmother grew the same plant in her yard. That trip made me permanently skeptical of "ancient formula" language on American supplement labels. The phrase almost always signals that someone copied it off another bottle, not that the product carries any particular heritage.
