Peptidia - The peptide encyclopedia — cited, neutral, nothing sold

Peptide info online is either a vendor blog that's secretly a sales page or a Reddit thread that contradicts itself by comment three. Peptidia is the third option: a source-cited encyclopedia — 20 dossiers covering mechanism, evidence quality, limitations and safety context, every claim carrying a PubMed/DOI citation. Plus Peptarch, an AI that answers with sources and flags thin evidence. No store, no affiliate links, no dosing content by design. $9.99/mo, or $59.99 lifetime for the first 100.

SideMission - Real-life missions that get you off your phone

SideMission gives you small real-life missions that push you out of passive scrolling and into actual experiences: solo resets, cafe missions, city exploration, date-night prompts, social courage challenges, and more. Complete missions, save proof, and share what you did.
