Tesamorelin: potential benefits
- Reduction of visceral adipose tissue (~15% at 26 weeks in the pivotal HIV trial; FDA-label indication)
- Reduction of hepatic fat content (NAFLD off-label indication)
- Elevated IGF-1 within the age-adjusted reference range
- Preserved pulsatile GH release (vs continuous elevation with CJC-1295-DAC)
- Improved body composition (VAT down, lean mass preserved)
- Sustained VAT reduction through 52 weeks with continued dosing
- FDA-approved - the only GHRH secretagogue with that status
L-Carnitine: potential benefits
- Enhanced fat metabolism
- Improved exercise performance
- Reduced muscle damage and recovery time
- Neuroprotective effects (acetyl-L-carnitine)
- Mitochondrial function support
- Improved insulin sensitivity

L-Carnitine is a weight loss that l-carnitine's mechanisms extend beyond the simple "fat-burning nutrient" label. understanding these mechanisms helps predict where supplementation will and will not produce…. The two differ in mechanism, half-life (30-50 minutes (plasma) vs not reported), and typical dose range.
Which has the longer half-life, Tesamorelin or L-Carnitine?
Tesamorelin has a half-life of 30-50 minutes (plasma). L-Carnitine has a half-life of not reported. Longer half-lives generally mean less frequent dosing but slower on/off kinetics.
