Hey PH 👋 I'm Benja. I built BioStackr because I was that guy — 13 supplements, zero idea which ones were actually doing anything. I'd read a study, watch a podcast, add another bottle to the shelf. Monthly spend kept climbing. "But I feel like they help" was the best I had. Then I started wearing a WHOOP and noticed something. On the days I skipped certain supplements, my sleep scores barely moved. Some got better. That was a problem — because I was paying for those. So I built the thing I wished existed. Upload your wearable data, tell it what you take, and let the math do what your gut can't — compare ON days vs OFF days with real statistics. What we're finding is pretty consistent: most people have at least one or two supplements in their stack that aren't doing a thing. Not because supplements are scams — but because individual response varies wildly, and "I feel like it works" was never going to catch that. BioStackr is early. The stats are real, the product works, but I'd genuinely love tough feedback — roast it, break it, tell me what's missing. That's how it gets better. Be honest: what's your monthly supplement spend, and how much of it is based on actual evidence vs vibes 👇
