Documented reference chemistry.
Tesamorelin — a 44-residue stabilized GHRH-analog research peptide — supplied by BioFusion as a vacuum-sealed lyophilized 5mg vial for full-length GHRH-pathway research chemistry.
Research context
Tesamorelin is the trans-3-hexenoyl-modified version of the natural 44-residue GHRH(1-44) sequence — a structural modification at the N-terminus that improves stability and receptor-research kinetics relative to native GHRH. As the longest standard reference in the GHRH research panel, Tesamorelin is the typical control compound when comparing the truncated CJC-1295 and CJC-1295 no DAC analogs against full-length GHRH.
Synthesis & documentation
Produced by solid-phase peptide synthesis using Fmoc protecting-group strategy in a U.S.-based ISO 9001:2008 facility, with the trans-3-hexenoyl modification incorporated post-cleavage. Each lot is verified for identity (LC-MS), purity (reverse-phase HPLC-UV ≥99.0%), moisture (Karl Fischer), and counter-ion (ion chromatography). Signed COA ships with every order; lot archive on the COA library.
Storage & handling
Lyophilized Tesamorelin is stable at −20 °C for the printed shelf life. After reconstitution, the standard 14-day-at-2-8 °C reference window applies; avoid freeze-thaw cycling. At 44 residues, Tesamorelin is more aggregation-prone than shorter GHRH analogs — use mild solvents (bacteriostatic water or saline) rather than aggressive co-solvents. The reconstitution calculator handles concentration math.
Why BioFusion
Synthesizing 44-residue peptides at ≥99% HPLC purity is technically demanding — sequence length increases the probability of single-residue deletion impurities. BioFusion’s Tesamorelin is purified to ≥99.0% reverse-phase HPLC purity at every release, with synthesis-date metadata on the batch transparency ledger. Bulk discounts at three+; members save 25% plus free U.S. shipping for 365 days.
For research and laboratory use only. This product is not a drug, food, or cosmetic, and is not intended for diagnostic, therapeutic, or in vivo human use.
Keep lyophilized until needed.
Store the lyophilized vial cool and dry, away from light, until your protocol calls for it. In freeze-dried form the material stays stable for extended bench storage.
Reconstitute as needed with the diluent your method specifies, then keep the prepared solution refrigerated and use it within your validated window.
