The Science of GHRH and GHRP Signaling Pathways

In 2026, the investigation of the somatotropic axis remains a cornerstone of regenerative and longevity science. Polaris Peptides provides the high-purity ligands necessary to study the intricate feedback loops between the hypothalamus and the anterior pituitary gland.

Selective Agonism: Ipamorelin & CJC-1295 Our San Diego

facility specializes in the production of GHS compounds designed for high receptor selectivity:

• Ipamorelin: A selective GHRP (Growth Hormone Releasing Peptide) investigated for its ability to stimulate GH release without significantly impacting cortisol, prolactin, or appetite-stimulating hormones (Ghrelin).

• CJC-1295 (Tetrasubstituted GRF 1-29): A synthetic analogue of GHRH. Researchers utilize the “No DAC” version for studying physiological GH “pulses,” while the “With DAC” version is utilized for investigating extended half-life and sustained plasma levels.

• Tesamorelin: A stabilized 44-amino acid GHRH analogue primarily studied for its impact on visceral adipose tissue and lipodystrophy models.

Analytical Integrity and “Zero-Degradation” Shipping

The somatotropic axis is highly sensitive to the precision of the ligands used in study. Trace impurities in GHS compounds can lead to “off-target” pituitary activation. At Polaris Peptides, our Triple-Point Verification (HPLC/MS/NMR) ensures that every vial is free from synthesis byproducts and residual TFA salts. Furthermore, our San Diego fulfillment center utilizes expedited, temperature-stable packaging to ensure that fragile peptide chains remain intact during transit to your laboratory.
