Sermorelin GHRH(1-29)-NH2 Research Peptide
Sermorelin is the C-terminally amidated 29-amino-acid fragment of human growth hormone-releasing hormone, commonly written as GHRH(1-29)-NH2 or GRF(1-29) amide. This region retains full GHRH-receptor agonist activity in experimental systems.
It is used in receptor, pituitary-cell and somatotropic-axis research. This product is not presented as a medicine, diagnostic agent or human-use preparation.

Independent Batch Testing
Every current ZENTRA batch is independently tested and records an HPLC purity result above 99%. Use the batch number printed on the product label to locate the corresponding third-party report in our Batch Verification and COA Centre. Researchers should consult the individual report for the exact analytical methods, result and testing date for their supplied batch.
Sermorelin Research Context
Published studies established that GHRH(1-29)-NH2 can activate the GHRH receptor and stimulate growth-hormone release in controlled research settings. It has also been investigated as a pharmacological probe of pituitary reserve.
Those findings concern regulated study material and defined protocols. They do not establish a self-use application for this research product.
Storage and Handling
Keep unopened lyophilised material at approximately -20°C for long-term storage or 2-8°C for short-term laboratory storage. Protect from light, moisture and repeated temperature changes.
Research FAQs
Sermorelin is the amidated first 29 amino acids of human GHRH.
Why is it written GHRH(1-29)-NH2?
The notation identifies residues 1-29 of GHRH and the amide group at the C-terminus.
Is Sermorelin the same as Tesamorelin?
No. Tesamorelin is a modified 44-amino-acid GHRH analogue; Sermorelin is the shorter 1-29 amide fragment.
What receptor does it activate?
Published research characterises it as a GHRH-receptor agonist.
How is purity checked?
The current batch is independently HPLC tested above 99% and linked to an online report.
Is this for human or veterinary use?
No. It is supplied strictly for laboratory research.
