What is Modified GRF (1-29)?

Modified GRF (1-29) is a peptide analogue of GHRH, first developed in the 1980s. Researchers discovered that the first 29 amino acids of GHRH retained all the properties of the full 44-amino-acid protein. This smaller fragment, known as GRF (1-29), effectively mirrors the activity of GHRH but has a very short half-life, limiting its therapeutic potential.

To address this, scientists further modified GRF (1-29) by substituting four amino acids to prevent degradation and oxidation, both during manufacture and transport as well as within the body. These modifications also increased its binding affinity to GHRH receptors. This enhanced version, known as Modified GRF (1-29), has a longer half-life and greater therapeutic potential. It is sometimes referred to as Mod GRF or tetrasubstituted GRF (1-29).

CJC-1295 No DAC vs. Modified GRF (1-29)

Modified GRF (1-29) is chemically identical to CJC-1295 No DAC. Both peptides consist of the first 29 amino acids of GHRH and include modifications to improve stability and effectiveness. These peptides are distinguished by their lack of the Drug Affinity Complex (DAC), which means they have a shorter half-life compared to CJC-1295 with DAC.

Key Differences

  • GRF (1-29): The original peptide with a very short half-life.

  • Modified GRF (1-29): Enhanced version with four substituted amino acids for better stability and receptor binding.

  • CJC-1295 No DAC: Identical to Modified GRF (1-29), lacking the Drug Affinity Complex.
