Tesamorelin vs CJC-1295

Growth Hormone

Tesamorelin and CJC-1295 are both GHRH analogs but occupy different positions in the peptide landscape. Tesamorelin (Egrifta) is the only FDA-approved GHRH analog — approved specifically for HIV-associated lipodystrophy — with strong clinical data on visceral fat reduction. CJC-1295 is a research peptide with modifications for extended half-life, especially the DAC version which provides weekly dosing.

Side-by-Side Comparison

AspectTesamorelinCJC-1295
costHigher — prescription drug pricingLower — research peptide pricing
dosing2 mg SubQ daily (standard protocol)100-300 mcg 2-3x daily (no DAC) or 300-1000 mcg 1-2x weekly (with DAC)
best forVisceral fat reduction, abdominal fat, metabolic syndrome, those wanting FDA-approved optionSustained GH elevation, anti-aging, body composition, stacking with GH secretagogues
mechanism44-amino-acid GHRH analog — rapid GH pulse, specifically studied for visceral fat reductionModified GHRH (1-29) — engineered for protease resistance; DAC version binds albumin for 6-8 day half-life
fda statusFDA-approved (Egrifta SV) for HIV-associated lipodystrophyNot FDA-approved; research peptide
side effectsInjection site reactions, joint pain, paresthesia, elevated IGF-1Flushing/head rush, water retention (more with DAC)
clinical evidenceStrong — multiple Phase 3 trials, FDA-approved, proven visceral fat reductionLimited — Phase 2 data available, not FDA-approved

Verdict

Tesamorelin for visceral fat and FDA-regulated safety. CJC-1295 with DAC for convenient weekly dosing and sustained GH. Tesamorelin has the clinical evidence advantage; CJC-1295 DAC has the convenience advantage.
