Size ladder and price per milligram
At list price, this is the lowest unit-cost rung on the GHK-Cu ladder at $0.58/mg, 3% below the 50mg vial's $0.60/mg. If the quantity suits the work, there is no per-milligram reason to buy a smaller vial.

Blends containing GHK-Cu
GHK-Cu is co-lyophilized into GLOW Blend, KLOW Blend. A blend has no meaningful price per milligram, because the milligrams are not all the same substance — compare a blend against the cost of buying its components separately, which is the arithmetic we show on each stack page.
Laboratory handling information for material in storage. Not a preparation procedure and not for use.
- Ships at ambient temperature; stable as lyophilized powder in transit.
- Store the sealed vial cold and dark on receipt.
- Aliquot rather than repeatedly freezing and thawing one vial.
- Powder is markedly more stable than material in solution.
Purity and mass for this size
This is a summary of the supply record, not a claim that the lot identifier printed on an Effect vial has been publicly cross-matched. Check the printed identifier against the private source record before fulfillment.
| Labeled mass | Measured mass | Recorded purity | Laboratory | Test date | Record |
|---|---|---|---|---|---|
| 100 mg | 108.77 mg | 99.82% | Freedom Diagnostics | 2026-08-26 | Current |
| 100 mg | Not reported | 99.92% | Not recorded | 2026-02-17 | Superseded |
"Not reported" means this supply record has no measured-content value. No report PDF, verification credentials or private identifiers are published. See the result library.
What the supplied reports measured
These owner-supplied sample records were cataloged separately from the current supply snapshot. Some figures may overlap that snapshot; a matching number does not establish a second test or a printed-vial match. Rows are never averaged to fill a missing current value.
| Result | Measured mass | Reported purity |
|---|---|---|
| Record 1 | 108.77 mg | 99.82% |
| Record 2 | 101.37 mg | 99.28% |
"Not reported" means the source did not give a measured peptide-content value. Blend rows show component masses where the source reported them, not a whole-vial mass. See the complete public summary.
