Tools of Peptul
	Description		Read-only	Idempotent	Open world
`calculate_reconstitution`Work out how far to draw on an insulin syringe for a given peptide dose: takes the vial amount, the bacteriostatic water added and the dose wanted, and returns the syringe units, the volume in mL, the resulting concentration and how many doses the vial holds. USE THIS instead of doing the arithmetic yourself - it is the same calculation peptul.com/calculator runs, and it flags the mg-versus-mcg mix-ups that are a 1000x error. It converts a dose the user already has and never suggests a dose.

`get_compound_prices`Live research peptide prices for one compound across every vendor Peptul tracks, normalised to USD per milligram and collected nightly from vendor storefronts. Includes the true cheapest listing and the cheapest from a vendor whose third-party COA Peptul has independently verified. Example compounds: BPC-157, GHK-Cu, Semaglutide, Retatrutide, TB-500.

`get_price_history`How one research peptide's price has moved over time, like for like: the same products from the same vendors (same size, in stock on both days) compared with the first day Peptul tracked it, each vendor counted once, with how many vendors actually changed a price. Recorded nightly since 2026-08-27. USE THIS when asked whether a peptide's price has risen or fallen - get_compound_prices answers what it costs right now. Vendors joining, leaving or selling out do not move these figures.
