"Growth-hormone peptide" is an umbrella term used in research for a whole range of molecules. In this guide we order the field, research-only: which families exist, how they relate to one another and which well-known examples belong to each group. Without any health or performance claims.
Growth-hormone peptides are research peptides around the release of growth hormone, split broadly into two families: GHRH analogues (including CJC-1295, tesamorelin) and ghrelin-mimetic GHRPs (including ipamorelin). They are not medicines and are offered for research only, ≥99% pure with a COA per batch.
What are growth-hormone peptides?
Growth-hormone peptides are short research peptides studied in science around the system that regulates the release of growth hormone. They are also called growth-hormone secretagogues. Rather than one molecule, this is a family with different points of focus. New to peptides? First read what peptides are.
Family 1: GHRH analogues
GHRH analogues are peptides that mimic growth-hormone-releasing hormone (GHRH). The best-known examples in research are CJC-1295, tesamorelin and sermorelin. They share a common theme but differ in stability and half-life — precisely the properties that make them separate objects of study.
Family 2: GHRPs (ghrelin mimetics)
GHRPs are peptides that take the ghrelin receptor as their point of focus instead of the GHRH receptor. Ipamorelin is the most studied, selective example of this; older GHRPs such as GHRP-2 and GHRP-6 also appear in the literature. Why are both families studied together? Because combinations of a GHRH analogue and a GHRP are a recurring subject in research, such as the CJC-1295 + Ipamorelin blend.
Which growth-hormone peptide for which research?
The choice between a GHRH analogue and a GHRP depends entirely on the research design, not on dosing or usage advice. See the full range in the muscle growth & growth hormone category, or dig into each molecule via the individual guides above. Every product is supplied as a lyophilised powder and reconstituted in the lab with bacteriostatic water — work out the ratio with the reconstitution calculator.
Purity and documentation
Reproducible research into growth-hormone peptides requires material with verified purity and full traceability. Every batch at LYSENTA is tested by Janoshik Analytical at ≥99% purity by HPLC and mass spectrometry, with a public certificate per lot number. Read more about our approach on the science page.

Frequently asked questions about growth-hormone peptides
What are growth-hormone peptides?
Growth-hormone peptides (GH peptides) are research peptides studied in science around the release of growth hormone. They fall broadly into two families: GHRH analogues and ghrelin-mimetic GHRPs. They are not approved medicines.
What is the difference between GHRH analogues and GHRPs?
GHRH analogues (such as CJC-1295, tesamorelin and sermorelin) mimic growth-hormone-releasing hormone. GHRPs (such as ipamorelin) are ghrelin mimetics that work through a different receptor. In research the two families are often studied together.
Which growth-hormone peptides are there?
Widely studied examples are CJC-1295, tesamorelin and sermorelin (GHRH analogues) and ipamorelin (a GHRP). Each has its own profile and is offered for research purposes only.
Are growth-hormone peptides pure at LYSENTA?
Yes, every growth-hormone peptide is lab-verified at ≥99% purity by HPLC and mass spectrometry, with a public Janoshik certificate per batch. For research purposes only.
