Key differences

Tesamorelin rests on stronger human evidence (Tier 1) than CJC-1295 (Tier 4) — that means more confidence its observed effects are real rather than artefacts of weaker study designs. Tesamorelin is FDA approved for specific uses, while CJC-1295 is not fda approved and treated as a research compound in the US.

CJC-1295 has 0 human trials on record (0 subjects) versus Tesamorelin's 6 (800 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 Tesamorelin?

Tesamorelin is a synthetic growth hormone-releasing hormone (GHRH) analog approved by the FDA (as Egrifta) to reduce excess visceral abdominal fat in people with HIV-associated lipodystrophy. It is supported by phase 3 randomized controlled trials for that specific indication. It is a prescription medication and is… Full Tesamorelin breakdown →

Where to buy CJC-1295 or Tesamorelin safely
