Tesamorelin Pre-Mixed Pen 2mg Peptide

Direct Anti Peptide is proud to offer the Tesamorelin Pre-Mixed Pen 2mg Peptide — a high-purity, pre-configured research tool engineered for accuracy, convenience, and compliance. Manufactured to ≥98% purity standards and supplied in a ready-to-use pre-mixed format, this product is intended exclusively for trained research professionals operating within controlled laboratory environments.

Product Overview

Tesamorelin is a synthetic analogue of growth hormone-releasing hormone (GHRH), composed of the full 44-amino acid sequence of endogenous GHRH with a trans-3-hexenoic acid group conjugated at the N-terminus. It has been widely studied in research contexts related to growth hormone secretion, metabolic regulation, and body composition modelling. The pre-mixed pen format offered by Direct Anti Peptide eliminates manual reconstitution steps, reducing the risk of preparation errors and improving reproducibility across experimental protocols.

Peptide Structure & Amino Acid Sequence

Tesamorelin is a 44-amino acid peptide analogue structurally derived from endogenous human GHRH(1–44). The addition of a trans-3-hexenoic acid moiety at the N-terminus enhances its stability and resistance to enzymatic degradation compared to native GHRH. This structural modification is a key focus of ongoing peptide stability and pharmacokinetic research. The molecular formula is C₂₂₁H₃₆₆N₇₂O₆₇S and it carries a molecular weight of approximately 5135.8 Da, making it a mid-to-large range research peptide with well-documented structural characterisation in the scientific literature.

Purity & Analytical Verification (HPLC & MS)

Every batch of Tesamorelin Pre-Mixed Pen 2mg Peptide supplied by Direct Anti Peptide undergoes rigorous analytical testing prior to release. High-Performance Liquid Chromatography (HPLC) is used to confirm purity at ≥98%, while Mass Spectrometry (MS) verifies molecular identity and sequence integrity. These dual verification methods ensure that researchers receive a product meeting the highest quality benchmarks expected in modern peptide science. Certificates of Analysis (CoA) are available upon request and reflect lot-specific testing data.

Quality Control & Lyophilisation Integrity

The Tesamorelin peptide used in this pre-mixed cartridge system is sourced from lyophilised stock that has been validated for structural integrity and biological activity consistency. The lyophilisation process preserves peptide conformation and prevents degradation during transit and storage. Each cartridge is pre-mixed with 2ml of pharmaceutical-grade bacteriostatic water under controlled conditions, eliminating variability introduced by manual reconstitution. This pre-mixed format is particularly valuable for high-throughput research environments where reproducibility and time efficiency are critical.

Safety, Handling & Laboratory Precautions

This product is intended solely for use by trained laboratory researchers and scientific professionals. It must be handled in accordance with standard laboratory safety protocols, including the use of appropriate personal protective equipment (PPE). Tesamorelin Pre-Mixed Pen 2mg Peptide is not approved for, and must never be used in, human subjects, animals, clinical trials, or any consumptive application. Researchers should consult relevant institutional biosafety guidelines before commencing work with this compound. Store away from direct light and heat sources, and keep out of reach of unauthorised personnel.

Reconstitution, Packaging & Storage

The pre-mixed cartridge format removes the reconstitution step entirely — each 2mg cartridge arrives pre-mixed with 2ml of bacteriostatic water, ready for immediate integration into your research workflow. The complete pen kit available from Direct Anti Peptide includes:

• 1 x Pre-Mixed 2mg Tesamorelin Cartridge (peptide pre-mixed with bacteriostatic water)
• 1 x Precision Peptide Cartridge Pen for accurate, repeatable dosing
• 1 x Hard Carry Case for secure transport and storage
• 3 x Disposable Pen Needle Tips

Multi-cartridge options (1, 2, or 3 cartridges) are also available for researchers requiring extended supply. Store cartridges refrigerated at 2–8°C when not in active use. Do not freeze. Keep sealed until ready for laboratory application.

Intended Research Use & Market Positioning

Tesamorelin has been extensively investigated in peer-reviewed research relating to growth hormone axis modulation, visceral adiposity studies, and metabolic research models. Its well-characterised structure and documented research history make it a preferred compound for investigators studying GHRH receptor biology, lipid metabolism, and body composition dynamics in controlled in-vitro and ex-vivo settings. Direct Anti Peptide positions this product as a premium, compliance-ready research reagent for academic institutions, independent laboratories, and contract research organisations.
