#CJC-1295

4 stories

CJC-1295 is a synthetic long-acting growth-hormone-releasing hormone (GHRH) analog. Like ipamorelin, it has been heavily marketed in the research-peptide and wellness market — typically paired with ipamorelin in 'GH-restoration' protocols at peptide clinics.

The regulatory picture matches the rest of the research-peptide cohort. CJC-1295 was named in Health Canada's public advisory against unauthorized injectable peptides; sits on the FDA Section 503A bulks list discussions; and was on the ProPublica-reported list of injectable peptides covered by the FDA's 2023 effective ban. State medical board enforcement against peptide clinics has included CJC-1295 in case files.

Clinical evidence for advertised wellness claims remains thin. Stories here cover regulatory action and any registered human trials. See #ipamorelin, #sermorelin, and #tesamorelin for adjacent tags.

Journal of Cachexia, Sarcopenia and Muscle (2026): Scoping Review Maps Peptides for Skeletal Muscle Wasting — Relevant to GLP-1-Era Lean-Mass Concerns

A 2026 scoping review in the Journal of Cachexia, Sarcopenia and Muscle catalogs peptides studied as therapeutic candidates and biomarkers in skeletal muscle wasting — covering sarcopenia, cancer cachexia, and ICU-related atrophy. The review documents MIF1/MIF2 myostatin peptide inhibitors, cachexia-targeting platform peptides, and the broader role of GH-axis peptides (CJC-1295, ipamorelin, tesamorelin) in muscle homeostasis. The clinical urgency lands harder now than it did pre-2024: Nature Reviews Endocrinology recently flagged sarcopenia and frailty as under-recognized GLP-1 receptor agonist side effects, with up to 40% of GLP-1-induced weight loss attributable to lean mass in the highest-loss patients. The review surfaces non-GLP-1 peptide candidates that could be paired with incretin therapy to protect muscle.
