about the
Somatropin 100 pen
Recombinant human growth hormone, supplied in a 3 mL / 300-click pen dosed in international units, for research.
Certificate of analysiswhy 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.

The pharmacopoeial identity standard for somatropin as a drug substance, covering peptide mapping, bioidentity, related proteins and host-cell impurities, is defined in the European Pharmacopoeia somatropin monograph maintained by the European Directorate for the Quality of Medicines (EDQM). That monograph describes the substance class; the excipient composition and expression-host details for this pen are reported in Veyvora’s batch documentation, which is where to read them before the material goes into a controlled protocol.
Assay Methods and What They Confirm
For how the principal assay method is measured and what it reports, see what HPLC purity does and does not prove. Researchers comparing pen formats across the catalogue can review the Growth & Recovery Research Pens category for context, and post-receipt handling requirements that follow from the pen’s format are covered in Veyvora’s storage and stability guidance.
Batch Documentation and Analytical Evidence
Veyvora states that each batch is tested first by Asterion Analytics and then again by Veyvora’s own internal testing, using HPLC, mass spectrometry and endotoxin assay, and that every Somatropin 100 IU Research Pen ships with an independent, batch-specific certificate of analysis (CoA) confirming identity and content (Veyvora, 2026). Verify your batch against the public CoA before committing the material to a protocol.
Reading the Certificate of Analysis
A batch-linked CoA documents the results of specific analytical methods applied to a specific production lot: the HPLC line reports purity, the mass spectrometry line confirms identity, and the endotoxin line reports the result for that lot. The certificate applies to the tested batch. Where UK laboratory testing is reported, the relevant accreditation body is the United Kingdom Accreditation Service (UKAS), which accredits laboratories against named methods; the laboratory’s accreditation status is recorded on the certificate.
Confirming Documentation Before Use
Request the following from Veyvora before incorporating the pen into a controlled in-vitro protocol:
- The batch number printed on the received unit
- The corresponding CoA, including the analytical methods used and the laboratory that performed each test
- Confirmation of whether the testing laboratory holds UKAS accreditation for the relevant methods
- The date of analysis relative to the stated shelf life
- Written confirmation that no batch substitution occurred between order placement and dispatch
Settle any of these items for the exact batch received before the material is used; the primary batch documentation is the record to work from.
Handling and Storage
Handling and storage instructions for the Veyvora Somatropin 100 IU Research Pen are supplied with the batch documentation; confirm them with Veyvora for the specific batch before the pen is committed to a protocol.
Storage Conditions
Store the pen at 2–8 °C, protected from light, and do not freeze. Licensed somatropin presentations in the UK are governed by product-specific Summary of Product Characteristics (SmPC) documents, which typically specify refrigerated storage at 2–8 °C, protection from freezing and light, and defined in-use periods; those conditions are a useful reference point for the same molecule, while the research pen’s own storage conditions and excipient composition are listed on its batch certificate.
Confirming Conditions Before Use
Request the following from Veyvora before the pen arrives in the laboratory:
- Written storage temperature range and whether freezing is permissible
- Stated shelf life and any in-use period once the pen is first activated
- Cold-chain packaging specification for transit, including the insulated bag and gel ice pack used
- Instructions for handling if the parcel arrives warm or the insulation or gel pack is compromised
Work from Veyvora’s written details for the specific batch received. Veyvora’s storage and stability guidance is the post-arrival reference.
