The Veyvora Skin Stack is a two-pen laboratory research bundle containing GHK-Cu 100 mg and Melanotan II 20 mg, supplied for in-vitro and laboratory research. As of 30 August 2026, the Skin Stack is listed as an active bundle on the Veyvora stacks page with a stated saving of 12% compared with purchasing each pen separately; the GBP bundle price is confirmed with the operator [1]. Confirm current pricing and availability directly with the operator before placing an order.
Skin Stack Pen Set, Specification Table
The table below reflects Veyvora product-page data as of 30 August 2026 [1].
| Pen | Active compound | Format | Dose per click | Supplied with |
|---|---|---|---|---|
| GHK-Cu 100 | Copper-binding tripeptide | 3 mL · 300 clicks | 333 µg | 10× 31G 6 mm needles, dosing card, CoA on request |
| Melanotan II 20 | Melanocortin-receptor agonist | 3 mL · 300 clicks | 67 µg | 10× 31G 6 mm needles, dosing card, CoA on request |
Two independent laboratories test every batch using high-performance liquid chromatography (HPLC), mass spectrometry and endotoxin assay before dispatch, with a batch-specific certificate of analysis (CoA) linked to the pen barrel number (Veyvora, 2026) [1].
Key Takeaways
- The Skin Stack bundles two separately characterised research reagents, GHK-Cu 100 mg (copper-binding tripeptide) and Melanotan II 20 mg (melanocortin-receptor agonist), at a stated 12% saving versus separate purchase.
- Every batch is tested by two independent laboratories using HPLC, mass spectrometry and endotoxin assay; a batch-specific CoA is available on request and keyed to the pen barrel number.
- Contact info@veyvora.com to confirm the GBP price, UK shipping charge and delivery timeframe before ordering.
- Both pens are supplied for in-vitro and laboratory research; GHK-Cu is studied in copper-peptide collagen-support work and Melanotan II in pigmentation research.
Exact Bundle Identity
The Skin Stack is a two-pen laboratory research bundle from Veyvora containing one GHK-Cu 100 mg copper-peptide pen and one Melanotan II 20 mg melanocortin-receptor agonist pen, supplied for in-vitro and laboratory research (Veyvora, 2026) [1].
Veyvora lists the Skin Stack on its stacks page under the descriptor “Copper-peptide collagen support with pigmentation research,” with both component pens named line by line beneath the stack heading [1]. The bundle carries a stated saving of 12% compared with purchasing GHK-Cu 100 and Melanotan II 20 separately; confirm the GBP bundle price with the operator (pages reviewed 30 August 2026) [1].

Included Components
The Skin Stack contains two independently characterised laboratory research pens, GHK-Cu 100 mg and Melanotan II 20 mg, each in a 3 mL, 300-click format with pen needles, a dosing card and a batch-specific CoA available on request (Veyvora, 2026) [1].
| Component | Strength | Format | Dose per click | Accessories | Source |
|---|---|---|---|---|---|
| GHK-Cu (copper-binding tripeptide) | 100 mg | 3 mL · 300-click pen | 333 µg | 10× 31G 6 mm needles, dosing card, CoA on request | [2] |
| Melanotan II (melanocortin-receptor agonist) | 20 mg | 3 mL · 300-click pen | 67 µg | 10× 31G 6 mm needles, dosing card, CoA on request | [1] |

GHK-Cu and Melanotan II belong to distinct mechanistic families — copper-binding tripeptide chemistry and melanocortin-receptor pharmacology respectively — which is why Veyvora groups them within its Skin & Aesthetics range by research area rather than by shared mechanism (Veyvora, 2026) [1]. Each pen carries independent HPLC purity and identity data reported per batch.
Consult Veyvora’s storage and stability guidance before receiving stock, and confirm the specific temperature requirements for each pen barrel with the operator prior to ordering [1].
State of the Evidence
Veyvora groups GHK-Cu 100 mg and Melanotan II 20 mg into the Skin Stack by shared research area. The Skin & Aesthetics category page describes the bundle as “Copper-peptide collagen support with pigmentation research” and notes that each pen is independently assayed [1]. GHK-Cu is studied for its copper-binding chemistry and extracellular-matrix and collagen-related signalling; Melanotan II is studied for its melanocortin-receptor pharmacology and pigmentation signalling. Each body of evidence sits at the individual compound level, and the bundle brings the two research areas together in one order (pages reviewed 30 August 2026) [1].
Veyvora’s site-wide framing is consistent with that map: products are supplied for in-vitro and laboratory research, with each pen documented on its own terms [1][3]. Researchers procuring the Skin Stack therefore work with GHK-Cu 100 and Melanotan II 20 as two separately characterised reagents bundled for convenience and price.
Where a protocol requires a copper-peptide blend rather than the pure tripeptide, the GLOW 70 Skin & Repair Pen is a separately listed component with its own batch documentation and specification sheet.
Batch Documents and Handling
Every Skin Stack pen ships with a batch-specific CoA available on request; the batch number printed on the pen barrel allows researchers to match the physical unit to its documentation before laboratory work begins [3]. Veyvora states that two independent laboratories test each batch using HPLC, mass spectrometry and endotoxin assay prior to release, with CoAs reporting identity and HPLC purity for each component independently [3][1].
The CoA reports chromatographic purity relative to the stated compound; HPLC purity does and does not prove explains how that figure is measured. Endotoxin assay results are reported separately and are particularly relevant for cell-based in-vitro protocols where contamination would confound results [1].
Pens are dispatched cold; confirm the specific °C storage range for GHK-Cu 100 and Melanotan II 20 against the individual component CoA or the supplier’s storage and stability guidance before receipt [1]. Each pen is supplied with 10× 31G 6 mm needles and a dosing card [1][3].
Receipt Verification
Upon receipt, procurement teams should check four items before logging the batch into inventory:
- Batch number on the pen barrel matches the CoA
- Temperature-indicator strip confirms cold-chain integrity was maintained in transit
- CoA endotoxin value meets the threshold required by the receiving laboratory’s protocol
- HPLC purity figure on the CoA corresponds to the declared compound for that barrel
Commercial Terms
Veyvora lists the Skin Stack with a stated saving of 12% compared with purchasing GHK-Cu 100 and Melanotan II 20 separately, as recorded on the stacks and Skin & Aesthetics category pages as of 30 August 2026 [1][3]. Contact Veyvora directly at info@veyvora.com to obtain the current GBP bundle price, lead times and applicable shipping terms [3].
For distributors, Veyvora states that wholesale supply begins at 50 units per SKU, with tiered pricing at 250 and 1,000+ units; all wholesale batches are independently assayed and shipped cold with batch-specific CoAs [3]. Veyvora asks distributors to work within the regulations of their own market [3].
Confirm UK VAT treatment, returns policy and minimum order quantities for non-wholesale buyers with Veyvora before placing an order (pages reviewed 30 August 2026) [1][3].
Research Use
Veyvora supplies every pen in the Skin Stack, GHK-Cu 100 and Melanotan II 20, for in-vitro and laboratory research, such as cell-culture models of collagen and extracellular-matrix signalling, melanocortin-receptor assays and use as analytical reference materials [1]. Not for human or veterinary use.
Veyvora’s category pages describe the research area and the per-pen documentation for the Skin Stack [1], and ask each buyer to work within the regulations of their own market [1].
Confirming Your Order
To confirm that a received pen matches its declared specification, verify a batch certificate against your pen using the batch number printed on the barrel. Contact Veyvora at info@veyvora.com to request current pricing, lead times and batch documentation before placing an order [3].
