Hey Product Hunt! I built Peptide Compare because I was tired of opening 30 browser tabs every time I needed to source a peptide. Prices vary wildly across vendors, purity is hard to verify, and the "review" sites are mostly fronts for a single vendor. So I built an independent comparison engine. A scraper runs daily across 60+ vendors, normalizes everything to per-milligram pricing, and pairs it with Janoshik lab purity data and Finnrick community trust scores. No vendor pays for placement — revenue comes from clearly disclosed affiliate links. A few things I'm proud of: - Head-to-head comparison pages (e.g. BPC-157 vs TB-500) with editorial guidance on when to use each - Vendor trust scores that combine lab testing, community ratings, and pricing consistency - A reconstitution calculator so you don't have to do syringe math at 6am Built with Next.js, Supabase, and a config-driven scraper running on a VPS. The whole thing started as a spreadsheet for personal use and grew from there. Would love your feedback — especially on what data you wish you had when choosing a peptide vendor. What would make this more useful for you?
