Ascend BioLabs GHK-Cu comparison: labels, sizes & COAs
Source-dated GHK-Cu comparison: specific PEL options, original sample documents, historical Ascend labels and unresolved differences.
Comparison in brief
The PEL 100 mg option is a different amount; a common material label alone does not establish a match.
Match GHK-Cu rather than a non-copper GHK label, then choose the size.
Compare the actual label and evidence
| Field | PEL source | Ascend BioLabs source |
|---|---|---|
| Material and labelled amount | GHK-Cu · 50 mg / 100 mg | The captured bundle listings specified GHK-Cu at 50 mg. |
| Source date | Live product identity rechecked September 15, 2026 (Pacific); sample reports retain their own dates. | Original plural-domain homepage captured September 11, 2026. Current product offer not verified. |
| Product options | Separate option links below. | Do not infer a standalone offer from a bundle or a search snippet. |
| Report access | 2 displayed original links; sample matching still required. | No current product-specific original authenticated for this comparison. |
| Current price and stock | Read the exact live PEL option, including checkout terms. | Not established by the archived observation. |
| Next unresolved question | Does the selected option and supplied lot correspond to the document? | Can the supplier provide the current label and its original lot-specific document? |

What the original PEL sample document says
GHK-Cu 50 mg · GHKCU012
Report V260211-2 037 names Vanguard Laboratory and is dated 2026-02-13.
| Field stated by the source | Reported result |
|---|---|
| Chromatographic purity (HPLC-UV/VIS) | >99.80% ± 0.18% |
| Quantity (HPLC-UV/VIS) | 46.81 mg |
The label is 50 mg; the stated quantity is 46.81 mg. Do not replace that measurement with the label amount. The original notes that the laboratory did not observe or participate in sample selection and cannot establish that it represents the associated lot. No endotoxin, microbial or sterility finding is supplied by this page.

|---|---|
| Chromatographic purity (HPLC-UV/VIS) | >99.80% ± 0.18% |
| Quantity (HPLC-UV/VIS) | 96.50 mg |
This is the 100 mg-labelled sample, separate from the 50 mg report. Its measured quantity is 96.50 mg, not the label amount. The original limits its findings to the submitted portion and states that sample selection and lot representativeness were not established by the laboratory.

Questions answered
Is 100 mg GHK-Cu the same option as 50 mg?
No. The amounts differ. Also distinguish GHK-Cu from non-copper GHK and from blends containing GHK-Cu. Select the actual amount and then match the original report.
Does a report prove the current item will be identical?
No. The report describes its identified sample. Check the physical lot, selected amount and supplier documentation before extending the result to an order.
Where can I check the current Ascend website?
Use the dated website-status record. A DNS hold or connection failure does not establish product quality, fraud or an order outcome.
Keep the source and decision together
The historical observation above comes from ascendbiolabs.com, captured September 11, 2026. It is not a finding about the separate singular-name storefront.
