Key differences
Sermorelin rests on stronger human evidence (Tier 2) than CJC-1295 (Tier 4) — that means more confidence its observed effects are real rather than artefacts of weaker study designs. Neither is FDA approved for human use — both are not fda approved / not fda approved and treated as research compounds in the US.
CJC-1295 has 0 human trials on record (0 subjects) versus Sermorelin's 2 (150 subjects). Evidence tiers are a shorthand for how strong that human data is — see our guide to understanding peptide evidence tiers for how to weigh them.
What is CJC-1295?
CJC-1295 is a synthetic analog of growth hormone-releasing hormone (GHRH 1-29), commonly studied alongside ghrelin-mimetic secretagogues. A DAC (drug affinity complex) variant is designed for an extended half-life. It is not FDA-approved and lacks published human efficacy randomized controlled trials; mechanistic data… Full CJC-1295 breakdown →
What is Sermorelin?
Sermorelin is a synthetic peptide corresponding to the first 29 amino acids of growth hormone-releasing hormone (GHRH 1-29). It was previously marketed in the United States (as Geref) for diagnostic and pediatric growth indications and is no longer sold as an approved product, though it remains available through… Full Sermorelin breakdown →
Where to buy CJC-1295 or Sermorelin safely
Both are sold by research-chemical suppliers, not pharmacies, so the source matters as much as the compound. Before buying either, vet sellers on third-party lab testing and enforcement history in the ranked directory of trusted peptide sellers — or jump straight to vetted sources for CJC-1295 or Sermorelin. PeptidesHub does not sell either compound.
