Overview
Tesamorelin — Growth hormone releasing factor analog
What is Tesamorelin?
Tesamorelin is a synthetic analog of growth-hormone-releasing hormone (GHRH), stabilised by a single N-terminal modification that protects it from the rapid enzymatic degradation native GHRH suffers. The result is a releasing-factor analog with a workable half-life — one of the cleanest levers available for endocrine and growth-hormone-axis research.
Why researchers choose it
Acting upstream in the GH axis, tesamorelin is a different experimental instrument from direct secretagogues: it lets a protocol interrogate the axis at the releasing-hormone step itself. REPRIME supplies lyophilized 10 mg and 20 mg vials, so reconstitution timing, diluent, and concentration remain the researcher's decisions.
The REPRIME standard
Every batch is tested by an independent laboratory and released at ≥99% HPLC purity; the batch COA is public on this page before purchase. Vials arrive cold-chain in tamper-evident packaging with a unique REP-XXXX-XXXX-X code — one scan at first use confirms yours is genuine. For laboratory and research use only.
Storage
Store lyophilized at -20°C. After reconstitution, refrigerate at 2-8°C.
Research use only
For laboratory and research use only. Not for human or animal consumption.

FAQ
Frequently asked questions.
What class of peptide is Tesamorelin?+
Tesamorelin is a stabilized analog of growth-hormone-releasing hormone (GHRH), studied in endocrine and GH-axis research.
How should Tesamorelin be stored?+
Store the lyophilized 10 mg and 20 mg vials at -20°C; after reconstitution refrigerate at 2–8°C and use within the period on the COA.
How do I verify the product is authentic?+
Each vial's insert carries a unique code in the format REP-XXXX-XXXX-X. Enter it on the /verify page — the first scan stamps it verified; a later scan warns the code has already been used.
