These figures are what pepmg still publishes about price: the floor, the middle, the spread and how many sources we track, computed from listings we captured first-party and refreshed on the same schedule as always. We no longer publish the individual listings or the sellers behind them.
Computed from 65 in-stock listings across 63 sources we captured first-party, with bulk vials, blends and statistical outliers excluded so the figures compare like with like. The spread is the highest tracked price divided by the lowest — how much the same milligram varies depending on where you look. The chart is the daily minimum; days we did not capture are left out rather than filled in.

▸ Why compare $/mg for GHK-Cu?
Per-mg prices for GHK-Cu vary widely due to differences in synthesis scale, purity levels, and vendor markup. Comparing prices helps researchers find cost-effective sources without compromising on quality, ensuring reproducible results.
▸ Reading the COA
Check the COA for identity via HPLC retention time and mass spectrometry, and purity should be ≥98% with no heavy metals or residual solvents. Common issues include under-filling (lower actual mg content) and adulteration with non-bioactive peptides or copper salts.
