Buy GHRP-2 (5mg x 5) & Mod GRF 1-29 (CJC-1295 no DAC) (5mg x 5) for GH Research
What Are GHRP-2 and Mod GRF 1-29?
GHRP-2 (Growth Hormone Releasing Peptide-2) and Mod GRF 1-29 (CJC-1295 no DAC) are two complementary peptides widely studied for their synergistic effect on growth hormone (GH) secretion.
-
GHRP-2 acts as a ghrelin receptor agonist, stimulating GH release directly through pituitary signaling.
-
Mod GRF 1-29, a modified analog of GHRH (Growth Hormone Releasing Hormone), enhances GH production by extending the half-life of native GHRH without altering natural GH pulse frequency.
Together, these peptides are known for potent, short-acting, and natural GH release patterns, ideal for studying metabolic regulation, tissue repair, and cellular recovery.
How Does the GHRP-2 & Mod GRF 1-29 Combination Work?
This pairing utilizes two distinct yet complementary biological pathways:
-
GHRP-2 triggers a direct GH surge by activating the ghrelin receptor (GHS-R1a).
-
Mod GRF 1-29 supports and amplifies this response by stimulating the pituitary gland to release GH naturally.
Unlike CJC-1295 DAC, the Mod GRF 1-29 version has a shorter duration, producing a natural GH pulse that mimics physiological secretion — making it ideal for precise and controlled research models.
