CJC-1295 / Ipamorelin vs Tesamorelin — evidence grades compared.
The honest verdict
Tesamorelin has the stronger evidence (Grade A vs CJC-1295 / Ipamorelin's Grade C).
Tesamorelin wins on evidence: it is the only FDA-approved drug (Grade A) in this matchup, proven to cut visceral fat, while CJC-1295/Ipamorelin (Grade C) has one PK study and no efficacy trial. The catch — tesamorelin is approved only for HIV-associated visceral fat, and CJC-1295/Ipamorelin isn't legally compoundable, so neither is a clean off-label muscle option.
CJC-1295 / Ipamorelin vs Tesamorelin: side by side
| Compared on | CJC-1295 / Ipamorelin | Tesamorelin |
|---|---|---|
| Evidence grade | Grade C | Grade A |
| Legal status | Research-only | FDA-approved |
| Safety | Limited human safety data, no major documented harms | Well-characterized human safety (FDA-approved or long clinical history) |
| Primary use | Muscle Growth | Weight Loss |
| Typical cost | $200–$400/month (stack) | High — branded Egrifta commonly $3,000+/month retail |
| One-line verdict | CJC-1295/Ipamorelin is not FDA-approved and is not legally compoundable (CJC-1295 withdrawn April 2026). Human evidence is Grade C — one PK study proves it raises GH/IGF-1, but no trial shows muscle or fat-loss benefit. Researching CJC-1295 on its own (often "with DAC")? See our standalone CJC-1295 page. | Tesamorelin is an FDA-approved drug (Egrifta, 2010) — Grade A, the strongest evidence tier here. But it is approved for HIV-associated visceral fat, not general weight loss; for that, approved GLP-1s are the evidence-backed route. |
