What is Tesamorelin?
Tesamorelin (Trans-3-hexenoic acid GHRH(1-44) analog) is a 44-amino acid full-length GHRH analog + fatty acid conjugate. Full-length GHRH(1-44) analog conjugated to trans-3-hexenoic acid, extending half-life while maintaining full GHRH-R agonism. FDA approved for HIV-associated lipodystrophy (abdominal fat reduction). Produces greater GH pulse amplitude than truncated GHRH analogs (sermorelin, CJC-1295) with full receptor occupancy.

Frequently Asked Questions
How do I reconstitute this peptide?
Add 1–2mL bacteriostatic water to the lyophilized vial by directing water down the inner wall of the vial. Swirl gently until the powder fully dissolves — do not shake or vortex. The solution should be clear and colourless. Use immediately or refrigerate at 2–8°C.
How should this peptide be stored?
Store lyophilized peptide vials at −20°C for long-term storage. Once reconstituted, store at 2–8°C (refrigerator) and use within 21–28 days. Avoid repeated freeze-thaw cycles, direct light, and heat exposure.
What purity is this QSC compound and how is it verified?
All QSC compounds are tested to ≥99% purity by HPLC peak area analysis on every production batch. Molecular identity is confirmed by mass spectrometry. A Certificate of Analysis (COA) is published on the product page and independently verifiable at verify.janoshik.com using the batch reference number.
