Tesamorelin and CJC-1295 get compared because they do the same biochemical thing — both are GHRH analogs that stimulate growth-hormone release. But the comparison is really about a single dividing line in the peptide world: one of them is an approved drug and the other is not. The table above is the row-by-row breakdown. Below is what each row means.
Tesamorelin vs CJC-1295: the short version
Tesamorelin is an FDA-approved medication (Egrifta) for excess visceral abdominal fat in adults with HIV-associated lipodystrophy, supported by randomized controlled trials. CJC-1295 is an unapproved research peptide with early-phase human pharmacology data and no controlled trials for the uses it is marketed for. Same drug class, opposite sides of the approval line.
Evidence: an approved label vs early pharmacology
This is the heart of it. Tesamorelin’s development included randomized controlled trials in HIV-associated lipodystrophy that were strong enough to earn FDA approval, and the formulation has since been updated (Egrifta SV, then the F8 formulation Egrifta WR approved in 2025). CJC-1295’s human record is early-phase pharmacology — it raises growth-hormone and IGF-1 — without controlled trials of the anti-aging or body-composition outcomes it is sold for. For how we weigh these tiers, see our how we grade evidence explainer, the full Tesamorelin evidence and regulatory record, and the CJC-1295 evidence and regulatory record.
Regulation: approved drug vs compounding limbo
Tesamorelin is a regulated medicine with an FDA label; its F8 formulation, Egrifta WR, was approved in 2025. CJC-1295 is the opposite case: per Frier Levitt it was removed from the FDA 503A “do not compound” Category 2 list in April 2026 but is not eligible for compounding and remains under PCAC review. In sport, both are prohibited at all times under the WADA S2 category for growth-hormone-releasing factors.
So which one, if either?
If the interest is the approved indication — visceral fat in HIV-associated lipodystrophy — Tesamorelin is the only one of the two that is a regulated, evidenced option, and that is a decision for a physician. For the general anti-aging and performance uses both are marketed for, neither has controlled human evidence, and CJC-1295 in particular remains research-only and unapproved.
