Report published
GHK-Cu / KPV is a two-component research blend labelled 50 mg / 20 mg per vial. Read the GHK-Cu total, its GHK peptide and copper breakdown, and the separate KPV amount under their own result labels. A report for standalone GHK-Cu does not replace this blend's batch documentation. Supplied as lyophilised powder for research use only.
Batch HK50KP20-0429 is linked to Janoshik task 156948, commissioned by the manufacturing partner. The submitted sample is recorded as ghk50mg-kpv20mg. This report is attached to the blend's batch, separately from the catalogue's standalone GHK-Cu product.
The batch record lists 61.55 mg GHK-Cu total, with 51.86 mg GHK peptide content and 9.69 mg copper content, plus a separate 23.79 mg KPV result. The peptide and copper entries describe the GHK-Cu breakdown; they are not extra amounts to add on top of the GHK-Cu total. The 50 mg / 20 mg label remains the labelled strength.
The report's recorded test scope is amount, with identity recorded as confirmed by the assay. No overall purity percentage is reported for this blend. Component amounts are not purity percentages, and this record supplies no sterility, endotoxin or heavy-metals results.
