Price Transparency Data
We track what research-peptide vendors actually charge — and publish the movements as open, machine-readable data. This is our own first-party dataset, normalized to a single comparable unit: price per milligram.
What this dataset measures
Each record is a single observed price change of 5% or more for a specific peptide and dosage at a specific vendor, within the trailing 30 days. For every change we record:
- ✓List price (USD). the advertised price before and after the change
- ✓Price per milligram (USD/mg). the normalized unit that makes vendors and dosages comparable
- ✓Percent change. the size and direction of the move
- ✓Observation date. when the change was recorded
- ✓Vendor & product. which vendor, which peptide, which dosage
How the data is collected
Prices are observed from vendors' own public product pages and normalized to price per milligram so that a 10 mg vial at one vendor can be compared honestly against a 5 mg vial at another. The dataset is regenerated daily; we surface only changes of 5% or greater to filter out rounding noise and keep the record meaningful.
This is observed transparency data, not real-time quotes and not purchasing advice. Prices change; always confirm the current price on the vendor's own site before buying. The dataset is independent of our affiliate relationships — every tracked vendor is measured the same way, partner or not.
