About Tesamorelin
Buy Tesamorelin 5mg at IGF1 Shop. Tesamorelin is a synthetic 44-amino-acid analog of human growth hormone-releasing hormone with a trans-3-hexenoyl moiety attached to the N-terminus, protecting against DPP-4 enzymatic degradation. This stabilization extends the half-life and the duration of GH release beyond what unmodified GHRH offers. Each Tesamorelin 5mg vial is HPLC-verified at ≥99% purity, ESI mass-spec confirmed, and accompanied by a per-lot Certificate of Analysis from an ISO 17025-accredited lab.

Tesamorelin — Mechanism & Specifications
Tesamorelin is a synthetic 44-amino acid analog of human growth hormone-releasing hormone with a trans-3-hexenoyl moiety attached to the N-terminus, protecting against DPP-4 degradation. Currently out of stock — restock expected within 4 weeks.
Quality & release criteria
Every lot of Tesamorelin is released only after passing reverse-phase HPLC (≥ 99% area purity at 220 nm against a reference standard), ESI mass spectrometry confirmation of molecular weight, and Limulus Amebocyte Lysate (LAL) endotoxin testing below 0.5 EU/mg. The lot-specific Certificate of Analysis is provided with the order and available on request before purchase.

FAQ
Tesamorelin — Frequently asked questions
What is Tesamorelin?
Tesamorelin is a synthetic 44-amino-acid analog of human growth hormone-releasing hormone (GHRH 1-44) with a trans-3-hexenoyl group attached to the N-terminus. The hexenoyl modification protects against DPP-4 degradation, dramatically extending the peptide's half-life relative to native GHRH. CAS 218949-48-5.
How is Tesamorelin different from Sermorelin and CJC-1295?
Sermorelin is GHRH(1-29) — the shortest active GHRH fragment, with a very short half-life. CJC-1295 (No DAC) is a substituted GHRH(1-29) analog with four amino acid changes for stability. Tesamorelin is GHRH(1-44) — the full-length GHRH with N-terminal hexenoyl protection. Tesamorelin shows the longest duration of action of the three at clinical doses.
What is the standard Tesamorelin dose?
Common protocols use 1-2 mg per subcutaneous injection, once daily before bed. A 5mg vial reconstituted with 2mL bacteriostatic water yields 250 mcg per 0.1mL, so a 1mg dose equals 0.4mL (40 units on a U-100 insulin syringe). Cycle length typically runs 12-26 weeks with periodic breaks.
How is Tesamorelin tested?
Each Tesamorelin lot is HPLC-tested to ≥99% purity, confirmed by ESI mass spectrometry against the theoretical 5,135.85 Da molecular weight, and endotoxin-tested by LAL to <0.5 EU/mg. ISO 17025-accredited third-party labs perform the testing; the per-lot COA ships with your order.
How do I store Tesamorelin?
Lyophilized Tesamorelin is best stored at -20°C protected from light; it is stable refrigerated at 2-8°C for shorter periods. After reconstitution with bacteriostatic water, refrigerate at 2-8°C and use within 14-21 days. Do not freeze the reconstituted solution.
