Tesamorelin Testing Methodology
Our analytical workflow for Tesamorelin follows USP <1225> guidance for validated chromatographic methods. Each lot is processed by a credentialed analyst with documented chain of custody.
Step 1
Sample intake & chain of custody
Your Tesamorelin sample (1-2 mg lyophilized) is logged at our Florida lab with a unique ID, photographed, and stored at -20 °C until analysis.
Step 2
Reverse-phase HPLC purity
Tesamorelin is dissolved in mobile phase and run on a C18 column with a water/acetonitrile gradient containing 0.1% TFA. UV detection at 214 nm quantifies the main peak and any related impurities.
Step 3
LC-MS identity confirmation
An aliquot is analyzed by liquid chromatography-mass spectrometry. The observed monoisotopic mass is compared against the theoretical molecular weight (5135.89 g/mol) for Tesamorelin to confirm identity.
Step 4
Impurity profiling & reporting
Related substances, truncations, and oxidation products are quantified. Findings are compiled into a signed Certificate of Analysis with chromatograms, mass spectra, and analyst interpretation.
Tesamorelin Purity Notes
Recommended research-grade purity for Tesamorelin is ≥95%. Lot-to-lot variation is common with solid-phase synthesis, so independent verification matters.
Common impurities to watch
- Truncated sequences from incomplete coupling
- Deletion peptides missing one or more residues
- Oxidation of methionine, tryptophan, or cysteine
- Residual TFA, acetate, or solvent counter-ions
- Aggregates and dimers from improper storage
What our COA confirms
- Main peak purity by HPLC area %
- Observed vs theoretical mass (5135.89 g/mol)
- Named impurities ≥ 0.1% area
- Net peptide content where applicable
- Method, column, and instrument metadata
Tesamorelin Handling, Storage & Safety
Guidance below is for laboratory and research personnel only. Tesamorelin is supplied for research use and is not intended for human or veterinary use.
Storage
Store lyophilized Tesamorelin at -20 °C, protected from light and moisture. After reconstitution, aliquot and store at -80 °C; avoid repeated freeze-thaw cycles.
Reconstitution
Reconstitute in bacteriostatic or sterile water in a clean environment. Allow vials to reach room temperature before opening to prevent moisture condensation on the powder.
PPE & shipping
Handle with gloves, lab coat, and eye protection. Ship samples to ACS overnight on dry ice or cold packs in a rigid, leak-proof container with a packing slip referencing your quote.
