Product Overview

Tesamorelin is a 44-amino-acid synthetic analogue of endogenous growth hormone-releasing hormone (GHRH). It was engineered to replicate the full biological activity of native GHRH while offering improved stability and a longer functional shelf-life. Within the research community, Tesamorelin has attracted significant scientific interest due to its selective action on somatotroph cells of the anterior pituitary gland, where it stimulates the pulsatile secretion of endogenous growth hormone. Researchers investigating metabolic regulation, body composition modelling, and neuroendocrine signalling pathways continue to explore Tesamorelin as a valuable molecular tool. Available for sale online through Direct Anti Peptide, this compound is positioned as one of the most analytically rigorous GHRH analogues on the market today.

Peptide Structure & Amino Acid Sequence

Tesamorelin consists of the complete 44-amino-acid sequence of human GHRH(1–44) conjugated at the N-terminus with a trans-3-hexenoic acid moiety. This structural modification significantly enhances resistance to enzymatic degradation by dipeptidyl peptidase IV (DPP-IV), extending the compound’s functional stability compared with unmodified GHRH. The full sequence retains all residues critical for receptor binding and downstream signalling, making Tesamorelin a structurally authentic and pharmacologically relevant research tool. Its molecular weight is approximately 5135.8 Da, and its molecular formula is C₂₂₁H₃₆₆N₇₂O₆₇S. Researchers sourcing this peptide from Direct Anti Peptide can be confident they are working with a structurally complete and sequence-verified compound.

Purity & Analytical Verification (HPLC & MS)

Every batch of Tesamorelin supplied by Direct Anti Peptide undergoes dual analytical verification using High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (MS). HPLC confirms that purity meets or exceeds the ≥98% threshold, while MS validates the precise molecular mass and confirms structural identity. Certificates of Analysis (CoA) reflecting these results are available upon request, ensuring full traceability and scientific confidence for research procurement teams and principal investigators alike. Researchers who buy Tesamorelin online from Direct Anti Peptide receive a compound backed by documented, reproducible analytical data.

Quality Control & Lyophilization Integrity

Lyophilization is the gold standard for preserving peptide bioactivity during long-term storage, and Direct Anti Peptide applies this process under strictly controlled temperature and pressure parameters. The resulting lyophilized cake is visually inspected for uniformity, and each sealed vial undergoes headspace integrity testing to confirm the absence of moisture ingress. Batch-to-batch consistency is maintained through standardized manufacturing protocols, ensuring that every order placed through our store delivers the same analytical profile and physical presentation.

Safety, Handling & Laboratory Precautions

Tesamorelin Peptide Vial is intended exclusively for use by trained laboratory professionals operating within appropriately equipped research facilities. Standard peptide handling precautions apply:

• Use appropriate personal protective equipment (PPE) including gloves and eye protection.
• Avoid inhalation of lyophilized powder during vial opening.
• Handle in a clean, controlled laboratory environment.
• Dispose of all materials in accordance with local institutional and regulatory waste guidelines.
• Keep out of reach of untrained personnel.

This product is not approved for any use outside of in vitro or controlled laboratory research contexts.

Reconstitution, Packaging & Storage

Tesamorelin Peptide Vial arrives sealed in pharmaceutical-grade borosilicate glass, chemically inert and resistant to compound interaction. The lyophilized format allows reconstitution in a laboratory-appropriate aqueous vehicle according to the specific requirements of the research protocol in use. For optimal preservation of compound integrity, store lyophilized vials at −20°C and protect from light and humidity. Once reconstituted, follow institutional guidelines for storage duration and conditions. Direct Anti Peptide ships all peptide vials with cold-chain-compatible packaging to maintain product quality throughout transit.
