Sermorelin vs Tesamorelin
Sermorelin and Tesamorelin are both growth hormone-releasing hormone (GHRH) analogs that stimulate pituitary GH secretion. Sermorelin corresponds to the first 29 amino acids of GHRH(1-44), while Tesamorelin is a modified full-length GHRH with a trans-3-hexenoic acid group. Tesamorelin is the only GHRH analog with FDA approval (for HIV-associated lipodystrophy), making these two compounds a natural pairing for comparative analysis.
CJC-1295 (with DAC) vs CJC-1295 (without DAC)
CJC-1295 exists in two distinct forms: with Drug Affinity Complex (DAC) and without DAC (also called Mod GRF 1-29). The DAC modification enables albumin binding for extended half-life, while the non-DAC version mimics more physiological GH pulsatility. Understanding the pharmacokinetic and pharmacodynamic differences between these two forms is essential for growth hormone research.
