Somatotropic research peptides

GHRH analogs and growth hormone secretagogues for somatotropic-axis research: CJC-1295, Tesamorelin and Ipamorelin. Research use only.

Quick answer

Somatotropic research peptides are tool compounds used in laboratory studies of the growth hormone axis. They fall into two groups. GHRH analogs, such as CJC-1295 and Tesamorelin, are modified forms of growth hormone-releasing hormone. Growth hormone secretagogues, such as Ipamorelin, act through a GHRP-like receptor instead. The category also lists a combined CJC-1295 + Ipamorelin vial. For research use only.

Questions

What is the difference between a GHRH analog and a GH secretagogue?
A GHRH analog is a modified growth hormone-releasing hormone, such as CJC-1295 or Tesamorelin. A growth hormone secretagogue such as Ipamorelin acts through a GHRP-like receptor rather than the GHRH pathway.
What is the difference between CJC-1295 DAC and CJC-1295 no DAC?
CJC-1295 DAC carries a reactive maleimidopropionic acid group that links it covalently to plasma proteins such as albumin, which extends its half-life and duration of action in published studies. The no DAC form lacks that reactive group.
How does tesamorelin differ from CJC-1295?
Both are GHRH analogs. Tesamorelin is human growth hormone-releasing factor (1-44) amide with a trans-3-hexenoyl group on Tyr1, which resists dipeptidyl aminopeptidase-IV. CJC-1295 DAC instead extends its action by binding albumin.
Are these peptides for human or animal use?
No. Every compound in this category is sold for laboratory research use only, not for human or animal consumption.

What is the difference between a GHRH analog and a GH secretagogue?

GHRH analogs and growth hormone secretagogues reach growth hormone release by different routes. GHRH analogs are modified forms of growth hormone-releasing hormone: Tesamorelin is human GRF(1-44) amide with a trans-3-hexenoyl group that resists dipeptidyl aminopeptidase-IV, and CJC-1295 binds albumin covalently through a reactive maleimidopropionic acid group, extending its duration of action. Ipamorelin is a synthetic pentapeptide secretagogue that acts through a GHRP-like receptor, described in 1998 as a selective growth hormone secretagogue.
