CJC-1295 (without DAC) vs Sermorelin

A side-by-side research comparison of CJC-1295 (without DAC) and Sermorelin drawn from Cedar Peptides' peptide database records.

CJC-1295 (without DAC)

CJC-1295 (without DAC), also known as Modified GRF 1-29 (Mod GRF 1-29), is a short-acting synthetic analog of growth hormone releasing hormone (GHRH). It is designed to stimulate endogenous growth hormone (GH) release in a pulsatile, physiologically consistent manner. Unlike the DAC-modified version, this variant has a very short half-life, allowing precise control over GH pulses and reducing the risk of receptor desensitization. It is primarily used in research focused on recovery, anti-aging, body composition, and endocrine function optimization.

Sermorelin

Sermorelin is a synthetic peptide corresponding to the first 29 amino acids of endogenous growth hormone-releasing hormone (GHRH 1–29), representing the shortest fully biologically active fragment. It functions as a physiologic stimulator of endogenous growth hormone (GH) secretion by acting on the anterior pituitary. Unlike exogenous GH administration, sermorelin preserves the natural pulsatile release of growth hormone, maintaining regulatory feedback mechanisms and reducing the risk of supraphysiological exposure. It is widely used in research contexts investigating growth hormone axis modulation, recovery, and metabolic regulation.

Reading a comparison

A comparison places two records side by side; it does not merge them. Each description above is drawn from that compound's own record, and the two were not necessarily characterised by the same methods, at the same time, or to the same level of detail. Before comparing any attribute, it is worth establishing that both records describe the substance you think they describe — names are not identifiers, and two entries sharing a name can differ in salt form, stereochemistry or the convention used to state a mass. Where a figure carries no method beside it, the comparison is between two reported numbers rather than between two measurements.
