Research Comparison
CJC-1295 (without DAC) vs Ipamorelin
A side-by-side research comparison of CJC-1295 (without DAC) and Ipamorelin 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.
Ipamorelin
Ipamorelin is a selective growth hormone releasing peptide (GHRP) that stimulates endogenous growth hormone (GH) secretion via activation of ghrelin (GHS-R1a) receptors in the pituitary. It is characterized by a highly selective profile, producing GH release without significant stimulation of cortisol or prolactin. This selectivity distinguishes it from earlier GHRPs, making it a preferred compound in research focused on body composition, recovery, sleep, and anti-aging. Its ability to preserve physiological GH pulsatility while minimizing off-target endocrine effects has positioned it as a core peptide in GH optimization protocols.
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.
