Key differences
Ipamorelin rests on stronger human evidence (Tier 3) 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 Ipamorelin's 0 (0 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 Ipamorelin?
Ipamorelin is a synthetic pentapeptide and selective growth hormone secretagogue that mimics ghrelin at the GHS-R1a receptor to stimulate pulsatile growth hormone release. It is not FDA-approved and has not been evaluated in published human efficacy randomized controlled trials; the evidence base is preclinical. It is… Full Ipamorelin breakdown →
Where to buy CJC-1295 or Ipamorelin 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 Ipamorelin. PeptidesHub does not sell either compound.
