Growth hormone research peptides are studied as growth-hormone secretagogues — compounds acting on the pathways that stimulate the body's own growth-hormone release. NextGen holds the CJC-1295 / Ipamorelin Blend, standalone Ipamorelin, and Tesamorelin, all in Australian stock, independently tested, with a Certificate of Analysis published before you order.

Products in this category

  • CJC-1295 / Ipamorelin Blend — both compounds combined in a single vial, pairing two different growth-hormone-secretagogue pathways.
  • Ipamorelin — a ghrelin-receptor agonist, studied standalone.
  • Tesamorelin — a GHRH analogue studied in its own right, distinct from CJC-1295.
  • GH Axis Stack — CJC-1295/Ipamorelin + Tesamorelin combined, for researchers studying the full axis together.

CJC-1295 vs Ipamorelin

CJC-1295 is a GHRH (growth-hormone-releasing hormone) analogue. Ipamorelin is a ghrelin-receptor agonist — a distinct class of GH secretagogue. Because they act on different receptor pathways, they're frequently studied together as a combined blend rather than in isolation.

Frequently asked questions

What are growth hormone research peptides?
A class of peptides studied as growth-hormone secretagogues — compounds studied for their action on the pathways that stimulate the body's own growth hormone release. Supplied strictly for laboratory and in-vitro research use only.

What's the difference between CJC-1295 and Ipamorelin?
CJC-1295 is a GHRH analogue; Ipamorelin is a ghrelin-receptor agonist. They act on different pathways, which is why they're frequently studied together as a blend.

What is CJC-1295 / Ipamorelin Blend?
A combined product pairing both compounds in a single vial, for researchers studying the two pathways together.

Are these peptides tested and CoA-backed?
Yes — every batch is independently tested for purity and identity, with the CoA published in our CoA Library before you order.
