Tesamorelin Nasal Spray

Tesamorelin Nasal Spray is a high-purity synthetic peptide formulation developed to support advanced scientific investigation into growth hormone secretagogue activity, visceral adipose tissue biology, and related metabolic research pathways. Available at ≥98% purity through Direct Anti Peptide, this product is supplied strictly for qualified laboratory environments. For research use only. Not for human or veterinary use. Not for clinical, diagnostic, or consumptive applications.

Product Overview

Tesamorelin is a synthetic analogue of growth hormone-releasing hormone (GHRH), engineered to stimulate endogenous growth hormone secretion from the anterior pituitary gland. The nasal spray format represents an innovative, non-injectable delivery format of interest to researchers studying transmucosal peptide absorption, bioavailability, and systemic peptide distribution. Direct Anti Peptide offers this formulation for sale to verified research institutions and qualified investigators seeking reliable, analytically verified material for in vitro and preclinical study designs.

Peptide Structure & Amino Acid Sequence

Tesamorelin is a 44-amino acid synthetic peptide corresponding to the full-length sequence of human GHRH(1–44), conjugated with a trans-3-hexenoic acid moiety at the N-terminus to enhance structural stability and resistance to enzymatic degradation. This modification is a key point of research interest when studying peptide half-life, receptor binding kinetics, and pharmacodynamic profiling in controlled laboratory settings. The intact GHRH receptor-binding domain is preserved, making this compound a valuable reference material in GH-axis research.

Purity & Analytical Verification (HPLC & MS)

Every batch of Tesamorelin Nasal Spray supplied by Direct Anti Peptide undergoes rigorous analytical verification prior to dispatch. High-performance liquid chromatography (HPLC) is employed to confirm peptide purity at ≥98%, while mass spectrometry (MS) validates molecular identity and confirms the absence of truncated sequences or synthesis by-products. Researchers can order with confidence knowing that each unit is backed by traceable quality data, ensuring experimental reproducibility and data integrity across research programmes.

Quality Control & Lyophilization Integrity

The peptide active component within this nasal spray formulation originates from a lyophilized bulk that has been processed under controlled conditions to preserve structural integrity and biological activity for research purposes. Lyophilization parameters are optimised to minimise moisture content and oxidative degradation, ensuring that reconstituted material maintains consistent physicochemical characteristics throughout the stated shelf life. Batch-level documentation is maintained to support research traceability requirements.

Safety, Handling & Laboratory Precautions

This product is intended exclusively for use by trained research professionals operating within appropriately equipped laboratory environments. Standard laboratory safety protocols must be observed at all times, including the use of appropriate personal protective equipment (PPE) such as gloves, eye protection, and lab coats. Researchers should consult applicable institutional safety guidelines and local regulatory frameworks before handling. This material is not approved for administration to humans or animals under any circumstances.

Reconstitution, Packaging & Storage

Tesamorelin Nasal Spray is supplied in a ready-to-use nasal spray format intended solely for laboratory research application.
