What Are Growth Hormone Peptides?
Growth hormone peptides are research compounds studied for how they stimulate or modulate the secretion of endogenous growth hormone from the anterior pituitary. This collection separates the two mechanistic classes researchers most often compare — GHRH analogs and GH secretagogues — plus the downstream growth-factor peptide IGF1-LR3. All are lyophilized, high purity, USA lab tested, for laboratory research use only.
GHRH Analogs vs GH Secretagogues
The first decision in a growth-hormone study is which receptor pathway to engage. GHRH analogs such as CJC-1295 w/DAC and Tesamorelin bind the GHRH receptor to prime pituitary somatotrophs. GH secretagogues such as Ipamorelin act on the ghrelin/GHS receptor through an independent, calcium-dependent mechanism. The CJC/IPA blend pairs both classes for co-activation studies.
Choosing by Research Focus
For fat-metabolism models independent of the GH receptor, AOD-9604 (a GH fragment) is the usual choice; for downstream IGF-1 receptor signaling, IGF1-LR3 provides a long-acting analog. Note that BPC-157 is sometimes confused with this class — it is a tissue-repair peptide, found in our Tissue Repair collection, not a growth hormone peptide.
Comparing Growth Hormone Research Peptides
| Compound | Class | Receptor / target studied |
|---|---|---|
| CJC-1295 w/DAC | GHRH analog (long-acting) | GHRH receptor |
| Tesamorelin | GHRH analog | GHRH receptor |
| Ipamorelin | GH secretagogue | Ghrelin / GHS receptor |
| AOD-9604 | GH fragment (176-191) | Lipolytic pathways |
| IGF1-LR3 | IGF-1 analog | IGF-1 receptor |
Frequently Asked Questions
What are growth hormone peptides in research? They are compounds studied for stimulating or modulating endogenous growth hormone secretion and the downstream IGF-1 axis in laboratory models.
How do GHRH analogs differ from GH secretagogues? GHRH analogs such as CJC-1295 and Tesamorelin act on the GHRH receptor; secretagogues such as Ipamorelin act on the ghrelin/GHS receptor. The two are often studied together for synergy.
What is Tesamorelin studied for? Tesamorelin is a GHRH analog researched for endogenous GH secretion and visceral-adipose-tissue metabolism models. It is a research compound only.
Is BPC-157 a growth hormone peptide? No. BPC-157 is a tissue-repair peptide and is listed under the Tissue Repair collection, not here.
Are these peptides approved for human use? No. Every compound in this collection is supplied strictly for laboratory research use only and is not approved for human or veterinary use.
