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.

Product Identity and Scope
Veyvora’s Tirzepatide 40 mg Research Pen is a pre-filled multi-dose click pen containing 40 mg of tirzepatide in a 3 mL barrel, delivering approximately 133 micrograms per click across 300 measured clicks (Veyvora product specification, 2026). The pre-filled format needs no reconstitution.
Tirzepatide is a synthetic dual GIP (glucose-dependent insulinotropic polypeptide) and GLP-1 (glucagon-like peptide-1) receptor agonist that binds to and activates two distinct hormone receptors involved in glucose regulation and appetite signalling. That dual mechanism separates it from single-receptor GLP-1 agonists such as semaglutide. The same molecule is the active substance of the SAHPRA-registered medicines Mounjaro, Persovance and Mounjaro KwikPen (Eli Lilly), prescription medicines registered in 2024 and 2025 in strengths from 2.5 mg to 15 mg [1]; the 40 mg research pen is a laboratory format with a larger total fill and click-based dispensing.
The specifications above reflect Veyvora’s published product data, and the batch-specific certificate of analysis that ships with each pen reports the measured values for the lot supplied. Once a batch number is allocated, verify your batch against its CoA to match the certificate to the pen, and read what HPLC purity does and does not prove for how the purity figure is measured and reported.
Verified Specifications
The figures below reflect Veyvora’s published product data. The batch-specific certificate of analysis (CoA) for the lot supplied reports composition, identity and purity as measured for that batch.
| Parameter | Veyvora-stated value (2026) | Where it is reported |
|---|---|---|
| Total tirzepatide content | 40 mg | Batch CoA |
| Fill volume | 3 mL | Batch CoA |
| Clicks per barrel | 300 | Batch CoA |
| Delivery per click | ~133 micrograms | Batch CoA |
| Excipients | Available from Veyvora | Batch CoA |
| Needle interface | 31G, 6 mm | Veyvora product data |
For comparison, the SAHPRA-registered tirzepatide pen in South Africa is Mounjaro KwikPen (Eli Lilly), registered in 2025 in strengths from 2.5 mg to 15 mg [1], with its specifications set out in the professional information approved by SAHPRA. The Veyvora 40 mg Research Pen is a laboratory presentation with a single 40 mg fill dispensed in 300 clicks, so the quantity dispensed is set by click count rather than by a fixed dose strength.
Before accepting delivery, read the storage and stability guidance for research peptides for what to check on receipt. For a compound-level comparison, the retatrutide versus tirzepatide comparison sets out the receptor-binding differences.
Batch Documentation and Analytical Evidence
Each Veyvora Tirzepatide 40 mg Research Pen ships with an independent, batch-specific certificate of analysis (CoA) reporting LC-MS identity, HPLC purity (≥ 98.0%), peptide content (95–105%) and a safety panel. The CoA is the analytical record for the lot supplied; match the certificate to the pen’s batch number, and Veyvora confirms on request which analytical methods and acceptance criteria were applied.
Reading the Certificate of Analysis
Each batch is verified independently by Asterion Analytics, then again by Veyvora’s own internal testing. The LC-MS line confirms identity by matching the measured mass to the expected mass of tirzepatide. The HPLC line reports chromatographic purity as area-percent at the detection wavelength, against the ≥ 98.0% acceptance criterion. The peptide content line reports the measured quantity against the stated fill, within 95–105%. The safety panel reports excipient identity, endotoxin and sterility status for the lot. For the registered product Mounjaro KwikPen, the corresponding identity, purity and stability criteria are set out in the professional information approved by SAHPRA [1], which is a useful reference for how the same molecule is specified in a medicinal presentation.
Where a batch number is provided at point of supply, verify your batch against its CoA before use; Veyvora confirms on request which analytical methods, reference standards and acceptance criteria were applied.
Handling and Storage
Dispatch temperature, excursion limits, in-use dating and stability data for the Tirzepatide 40 mg Research Pen are available from Veyvora on request; ask for them alongside the batch documentation so that receipt and storage can be planned before the pen arrives.
Storage Conditions
Store the pen at 2–8 °C, protected from light, and do not freeze. For the registered product Mounjaro KwikPen, the manufacturer’s Summary of Product Characteristics, as published in the UK electronic medicines compendium, specifies refrigerated storage at 2–8 °C, protection from light, and defined in-use periods after first use [2]; those conditions are a useful reference point for the same molecule, while the research pen’s own excipient composition is reported on its batch certificate.
For detailed guidance on what cold-chain receipt and 2–8 °C storage mean in a research-peptide context, see storage and stability guidance for research peptides. Inspect the cold-chain packaging on arrival, and confirm post-receipt handling with Veyvora where the laboratory’s workflow needs it.
