Tesamorelin + Ipamorelin Blend
Components: Tesamorelin acetate + Ipamorelin acetate
Tesamorelin CAS: 218949-48-5
Ipamorelin CAS: 170851-70-4
Tesamorelin Molecular Formula: C221H366N72O67S
Ipamorelin Molecular Formula: C38H49N9O5
Chemical Description
This product is a lyophilized peptide blend containing a synthetic 44–amino acid growth hormone–releasing hormone analog (tesamorelin) combined with a selective growth hormone secretagogue pentapeptide (ipamorelin).
Tesamorelin is modified at the N‑terminus with a hydrophobic acyl moiety to enhance stability against enzymatic degradation, while ipamorelin is a small peptide designed for potent and selective stimulation of growth hormone release in experimental systems.
Both components are supplied as acetate salts in a single vial for simplified handling in in vitro and ex vivo research applications.
General Properties
- Appearance: White to off‑white lyophilized powder
- Peptide class: Growth hormone–releasing factor analog + growth hormone secretagogue
- Form: Acetate salts, sterile‑filtered, lyophilized
- Solubility: Freely soluble in sterile aqueous buffers; limited solubility in most anhydrous organic solvents
Usage Notes
The tesamorelin + ipamorelin combination is intended for controlled laboratory studies of growth hormone axis modulation, peptide synergy, and receptor signaling in cell culture or ex vivo models.
Researchers typically reconstitute the lyophilized powder with sterile aqueous diluent and may further dilute into assay buffer or culture media according to experimental design.
Storage and Stability
Store lyophilized vials at or below −20°C in a tightly sealed container, protected from light and moisture.
After reconstitution, aliquot and store at −20°C or below; avoid repeated freeze–thaw cycles to maintain peptide integrity.
Structural Classification
Compound type: Peptide blend consisting of a long‑chain growth hormone–releasing hormone analog and a short‑chain growth hormone secretagogue.
