Show HN: Peptide calculators ask the wrong question. I built a better one Most peptide calculators ask the wrong question. They ask: How much water are you adding? But in practice, what you actually know is your vial size and your target dose . The water amount should be the output , not the input . It should also make your dose land on a real syringe tick mark. Not something like 17.3 units. I built a peptide calculator that works this way: https://ift.tt/n5O7ZRT What’s different: - You pick vial size and target dose → reconstitution is calculated for you - Doses align to actual syringe markings - Common dose presets per peptide - Works well on mobile (where this is usually done) - Supports blends and compounds (e.g. GLOW or CJC-1295 + Ipamorelin) - You can save your vials. No account required. Happy to hear feedback or edge cases worth supporting. https://ift.tt/n5O7ZRT January 31, 2026 at 11:02PM
