Certificate of analysis

why a pen beats
a vial & syringe

Traditional research peptides arrive as lyophilised powder that must be reconstituted, drawn into insulin syringes, and converted from milligrams to units by hand, every step a chance for a dosing error.

A multi-dose pen removes the whole failure chain. The peptide arrives already dissolved and calibrated. Attach a fresh needle, turn the dial until you count your clicks, and you're done, the same audible-click mechanism trusted in insulin and GLP-1 pens worldwide.

Pens travel and store better, too: no open vials, no bent needles, no septum contamination after repeated draws. One sealed barrel, ten sterile needles, one dosing card.

how to buy
peptides safely

The peptide market has a purity problem: independent surveys routinely find underdosed, mislabelled or contaminated product sold online. The only reliable defence is third-party verification you can check yourself, not a supplier's own claims.

Before buying any peptide pen, ask three questions. Is every batch tested by an independent lab? Is the certificate of analysis available, so you can check your exact lot before first use? And does it ship cold-chain, insulated and gel-packed, so what was tested is what arrives?

Veyvora answers yes on every order, independent assay, a CoA on request against the batch number, and cold dispatch within 24 hours, paperwork packed inside.

ProductMelanotan II 20 mg Research Pen
Labelled fill20 mg per pen
FormatMulti-dose research pen, 3 mL, 300-click
Supply basisIn-vitro laboratory research use only

Veyvora’s Melanotan II 20 mg Research Pen is a 3 mL, 300-click multi-dose pen containing 20 mg of Melanotan II (CAS 121062-08-6), specified at approximately 67 micrograms per click, supplied for in-vitro laboratory research (Veyvora product specification, 2026). Melanotan II is a synthetic cyclic heptapeptide analogue of α-melanocyte-stimulating hormone (α-MSH) [1], studied for its activity at the melanocortin receptors. The pre-filled pen format gives a laboratory a ready-to-use, batch-numbered presentation of the compound.

Each pen ships with a batch-linked certificate of analysis (CoA). Confirm current GBP pricing, stock status and delivery terms directly from the live Veyvora en-GB product page, dated to the day of purchase, as these figures are not reproduced here.

This page covers how the pen’s specifications are structured and what each parameter means; what a batch CoA contains and how to match it to your unit; and what ordering and handling steps apply before commencing in-vitro work.

Product Identity and Scope

The Veyvora Melanotan II 20 mg Research Pen contains 20 mg of Melanotan II (CAS 121062-08-6) in a 3 mL, 300-click multi-dose pen. The active substance is a synthetic cyclic heptapeptide analogue of α-MSH with the sequence Ac-Nle-c[Asp-His-D-Phe-Arg-Trp-Lys]-NH₂, supplied for in-vitro laboratory research [1]. For the underlying melanocortin-receptor mechanism and evidence context, see Melanotan II research explained.

The labelled fill of 20 mg across 300 clicks gives a nominal delivery of approximately 67 micrograms per click, based on the Veyvora product specification (2026). Current GBP pricing, stock status and delivery terms are not reproduced here; confirm these figures directly from the live Veyvora en-GB product page, dated to the day of purchase.

Verified Specifications

The table below lists the parameters drawn from the Veyvora product specification (2026). Per-click delivery is calculated from labelled fill and click count, so it is a nominal figure; the measured content for a lot is on its CoA.

Values Reported per Lot

Declared purity (% by high-performance liquid chromatography, HPLC), residual solvent levels, endotoxin specification, fill-weight tolerance and solvent or excipient composition are lot-specific values. Take each from the current Veyvora en-GB product page or the batch-linked CoA for the lot in hand, rather than from generic peptide industry thresholds.

Batch Documentation and Analytical Evidence

The batch-linked CoA is the document that reports the identity, purity and quality attributes of the specific unit in a researcher’s hand. A catalogue-level purity statement describes the specification the product is made to; the CoA reports the measured result for the lot shipped.

What a Valid CoA Should Cover

For a research peptide such as Melanotan II (CAS 121062-08-6), a CoA names the analytical methods applied to that lot, typically HPLC for identity and purity, mass spectrometry (MS) for molecular confirmation, and an endotoxin assay, and states the result against a defined acceptance criterion. ICH Q6B (1999) sets out the framework for what a biotechnological or biological specification addresses (identity, purity, impurities, quantity and other quality attributes), a useful reference for reading the sections of a batch certificate.

Veyvora Batch Documentation

Veyvora states that each batch is tested by two independent laboratories using HPLC, MS and endotoxin assay, with a published CoA to check against the batch number before first use (Veyvora quality documentation, 2026). Retrieve the current CoA directly from Veyvora and match the lot number printed on the pen or carton before use. Where the document names an accredited laboratory, record that laboratory’s name and the report date exactly as they appear on the document.

For how HPLC purity is measured and what the figure reports, see how HPLC purity is measured. To match a pen’s batch number to its published certificate, follow the steps at verify a batch against its CoA.

Handling and Storage

Take the storage and handling conditions for the Veyvora Melanotan II 20 mg Research Pen from the current product label, insert or structured data sheet, and confirm on arrival that the shipment’s temperature indicator strip shows no excursion.

Veyvora states that orders are dispatched in insulated, gel-packed 2–8 °C mailers with a temperature indicator strip (Veyvora fulfilment specification, 2026). Confirm current shipping terms with Veyvora when placing an order.

Laboratory Receipt Checklist

On receipt, record the following before proceeding with in-vitro work:

  • Confirm the temperature indicator strip shows no excursion from the labelled range.
  • Match the lot number printed on the pen or carton to the published CoA.
  • Note the labelled fill (20 mg) and any in-use period stated on the insert.
  • Store the pen under the conditions printed on the current label.
  • Document the receipt date, lot number, storage location and the name of the person accepting delivery in the laboratory record.
  • Retain the original packaging and temperature strip as part of the batch record.
