The Peptide Price Index

Deliberately vendor-blind. Every price is an aggregate across the in-stock suppliers we track. No vendor names, no per-vendor breakdowns. Each strength cell uses the arithmetic mean of standard-package per-vial prices when available; otherwise the mean uses the available package quantities, each normalized per vial. Mixed packages are not an exact package-price comparison.

Range and lane. The range glyph draws the lowest and highest priced offer against the mean at its center tick, so a wide glyph means the sources disagree; single-source cells show no glyph. Domestic lanes typically price above international ones. Blends and oils show no $/mg (two compounds, or a per-ml concentration). Prices are TitrateLab retail with margin included and shipping excluded; your exact package, lane and delivered total are quoted at order time. Research use only.

Source counts. The first number is the suppliers priced into the mean. The second is every distinct supplier with that product in stock for your delivery lane across the full pricelists we track, counted only if the pricelist passed validation and the offer was seen within the last 30 days. A frozen or quarantined listing never inflates the number. For the few products we cannot match in the supply feed, the count falls back to the suppliers currently priced in the catalog. Today the means come from 5 priced suppliers; 6 are tracked.

Priced means a supplier's current offer enters a published mean: its checkout-priced offer where one exists, otherwise its catalog offer.

Median $/mg across market is $1.08. It mixes very different compounds and is a scale reference, not a benchmark. The snapshot date is the catalog build date, not a per-source observation date.

Compare $/mg within one compound; a larger vial almost always lowers it. A single-source cell is one supplier’s asking price, not a market.
