about the
Tesamorelin 20 pen
Tesamorelin is a stabilised growth-hormone-releasing-hormone analogue, supplied in a 3 mL / 300-click pen 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.

Product Identity and Scope
Veyvora supplies the Tesamorelin 20 mg Research Pen as a 3 mL pre-filled multi-dose pen, batch-numbered on the barrel, for in-vitro laboratory research (Veyvora, 2026) [1][2].
Veyvora describes tesamorelin as a stabilised growth-hormone-releasing hormone (GHRH) analogue and positions the pen within visceral-fat and growth-hormone-axis research programmes [1][2]. The product page closes with the statement “For research reference only”, consistent with the site-wide statement that all peptides are supplied for laboratory research use [1][2]. Researchers receiving a unit should verify their batch against its CoA before first use, since the barrel batch number is the controlling link between the physical pen and its documentation.
Tesamorelin is the active substance of Egrifta, whose EU marketing-authorisation application was withdrawn on 21 June 2012 according to the European Medicines Agency (EMA) record [4]; no tesamorelin medicine is registered in the South African Health Products Regulatory Authority (SAHPRA) Registered Health Products Database as of 2026 [6]. The research pen is a laboratory presentation.
Verified Specifications
Each click of the Tesamorelin 20 mg Research Pen delivers approximately 67 µg, the arithmetic result of 20 mg divided by 300, as stated in the product specification (Veyvora, 2026) [1]. Each unit ships with 10 × 31G 6 mm pen needles in the box [1].

Veyvora describes the pen as sealed and ready to prime, with the barrel batch number linking the physical unit to its CoA [1][2]. The full excipient list, fill volume by mass and amino-acid sequence are reported in the batch documentation rather than on the product page. Researchers requiring those values can request the batch-specific CoA or consult the tesamorelin research profile for compound background before ordering [1][2].
Batch Documentation and Analytical Evidence
Every Tesamorelin 20 mg Research Pen carries a batch number on the barrel, and Veyvora makes a CoA available on request, matched to that specific lot number [1][2]. The testing laboratory, analytical methods and numerical purity, endotoxin and sterility values for a specific tesamorelin batch are reported on its CoA rather than on the product page [1][2]; the CoA is the controlling document for batch-specific purity.
Veyvora’s category pages state that each pen is independently assayed and that the CoA reports identity and high-performance liquid chromatography (HPLC) purity [2]. The specific lot result, detection limits and endotoxin threshold are read from the batch document [1][2].
Researchers comparing formats across the Growth & Recovery research pens catalogue can request the CoA before placing an order; batch-level analytical data is the basis for the documentation review. For post-receipt handling considerations, including storage conditions that affect sample integrity, see Veyvora’s research-peptide storage and stability guidance.
Handling and Storage
Veyvora dispatches the Tesamorelin 20 mg Research Pen cold, packed in an insulated sleeve with an ice pack, and ships within 24 hours to South Africa [3][5]. Order paperwork is included inside the parcel [1][3]. The stability window, beyond-use date and storage temperature range are stated on the batch CoA or the insert supplied with the order [1][3]; store the pen as the insert directs.
Storage conditions can vary by batch and fulfilment route, so the batch-specific insert and dispatch materials are the primary handling references for any given lot. Before first use, verify your batch against its CoA to confirm that the received pen matches the documented analytical result. For how HPLC purity data is measured and reported, see what HPLC purity does and does not prove.
Ordering Information
Veyvora lists the Tesamorelin 20 mg Research Pen as an active product dispatched to South Africa, with cold shipping within 24 hours and order paperwork packed inside the parcel [1][3]. The purchase price in ZAR is confirmed at checkout [3]. Minimum order quantity, shipping fees and live stock levels are confirmed with Veyvora at the point of purchase [1][3].
A CoA is available on request and matched to the batch number on the pen barrel, providing lot-level traceability between the physical unit and its documentation [1][2]. Researchers who need compound background before committing to an order can consult the tesamorelin research profile; those who need reference values for the pen format can refer to the tesamorelin dosing-card reference values.
Research Use
The Tesamorelin 20 mg Research Pen is supplied for in-vitro laboratory research, such as GHRH-receptor signalling assays, cell-culture work and use as an analytical reference material [1][2]. Not for human or veterinary use. The Tesamorelin 20 page closes with the notice “For research reference only” [1][3], and the product page contains no dosing protocols or treatment directions.
For post-shipment handling within a research setting, research-peptide storage and stability guidance covers considerations beyond the dispatch summary on this page. Researchers comparing nearby formats in the same research category can browse the Growth & Recovery research pens catalogue [2].
Related Research and Comparison Pages
Veyvora positions the Tesamorelin 20 mg Research Pen within two distinct category ranges: the Growth & Recovery research pens catalogue, which groups tesamorelin alongside other GHRH-axis compounds and includes a head-to-head comparison page for this peptide class [2], and the Metabolic & Weight research pens range, which places tesamorelin alongside compounds such as tirzepatide and retatrutide, organised by receptor profile and research pathway [3].
Before committing to a purchase, researchers should verify their batch against its CoA by matching the barrel lot number to the corresponding certificate of analysis. The batch document is the controlling source for purity and endotoxin values [1][2]. For a precise account of how HPLC purity is measured and how identity is confirmed, what HPLC purity does and does not prove provides the methodological context.
