Tracked medians showed mixed direction
Movement is based on each peptide’s median effective price per milligram, with ±0.5% treated as approximately flat.

The largest changes in median effective $/mg
These are market-lane medians—not a single vendor’s promotion or a claim about completed transactions.

Median prices at a new tracked low
Requires at least 14 qualifying observations and three current vendors. Gaps are not interpolated.
No qualifying new median lows
The absence of a new low is itself retained with this edition; PB does not force a headline when the data does not support one.
MARKET DEPTH
The most broadly priced peptide lanes
Vendor and offer counts help readers distinguish broad market signals from thinner listings.

METHODOLOGY & CITATION
What this report measures—and what it does not
Every edition carries its construction and coverage snapshot so later citations are interpreted against the data available at publication.
Tracked listing prices
Median effective USD per milligram across exact-comparability offers, using the discount rules recorded with each pricing snapshot.
Fixed-cohort index
Equal-weighted fixed cohort. Each eligible peptide is normalized to 100 at its first observation; daily index values average available normalized medians and require at least 70% cohort coverage.
Coverage limits
This is a tracked-listing index, not a transaction-price index. Vendor mix, availability, quantities, discounts, and catalog coverage can change over time.
