What Is Sermorelin?
Sermorelin is the first 29 amino acids of the 44-amino acid growth hormone-releasing hormone (GHRH) sequence — designated GHRH(1-29)NH2. This truncated fragment retains full binding and activation capability at the GHRH receptor (GHRHR), making it functionally equivalent to endogenous GHRH while being more practical to synthesise and study.
Preclinical research has focused on Sermorelin as a tool for studying pituitary somatotroph function, age-related decline in GH secretion, body composition changes, and metabolic effects downstream of GH axis activation. It is frequently compared to other GHRH analogues such as CJC-1295 (which uses albumin-binding DAC technology for extended half-life). Eternal Peptides Wholesale also stocks the CJC-1295 + Ipamorelin combination blend (CP10) for researchers studying GHRH/GHSR co-administration.
For GHRH + GHSR agonist combination research, see the CJC-1295 + Ipamorelin Research Guide. For research use only.

Frequently Asked Questions
Where can I buy Sermorelin in Australia? +
Eternal Peptides Wholesale is an Australian-owned, ABN-registered distributor supplying Sermorelin for research purposes. SMO5 (5mg, box of 10) is $495.00 and SMO10 (10mg, box of 10) is $693.00. Janoshik-verified with COAs on each product page. Dispatched within 1-2 business days. For research use only.
What is Sermorelin used for in research? +
Sermorelin is used to study pituitary somatotroph function, pulsatile GH release, age-related decline in the GH axis, and downstream metabolic effects of GH stimulation. As a GHRH(1-29) analogue it provides a research tool for the native GHRH signalling pathway. For research use only.
What is the difference between SMO5 and SMO10? +
SMO5 is 5mg per vial (box of 10, $495.00). SMO10 is 10mg per vial (box of 10, $693.00). Concentration selection depends on your research protocol. Both are Janoshik-verified. For research use only.
How does Sermorelin differ from CJC-1295? +
Sermorelin is GHRH(1-29) with a relatively short half-life, enabling research into pulsatile GH release patterns. CJC-1295 uses Drug Affinity Complex (DAC) technology for albumin binding, extending its half-life significantly for sustained release studies. Eternal Peptides Wholesale stocks CJC-1295 in the CP10 combination blend with Ipamorelin. See the CJC-1295 + Ipamorelin Guide. For research use only.
How is Sermorelin quality verified? +
Every batch is tested by Janoshik Analytical — HPLC purity, mass spectrometry identity, sterility (USP), endotoxin (LAL), heavy metals (ICP-MS). COA published on the product page, independently verifiable at janoshik.com. For research use only.
How quickly is Sermorelin dispatched? +
Orders are dispatched within 1-2 business days of payment confirmation from Australia. COA documentation is included with every order.
