what it is

Use TruePeptideSource inside ChatGPT, Claude or any MCP client: peptide doses labelled by origin, side effects, storage and exact reconstitution, blend and supply math. Free, no sign-in. Ask your assistant about a peptide and it pulls our dose ranges, side effects and storage, then runs our calculators for the syringe math. Six tools, all reading the same records and calculators as this site. Dose ranges and protocols, each labelled by where the number came from, plus side effects, storage, half-life, FDA status and what Reddit communities report.
