Verdict
Tesamorelin wins for targeted visceral fat reduction (VAT/NAFLD), proven clinical effects, and single daily dosing. If you need to crush GH gut or liver fat, there's nothing more effective—this is what the data actually supports.
Ipamorelin wins for ease of daily use, side-effect profile (no cortisol or prolactin spike), versatility in sleep/recovery/connective tissue protocols, and stackability with GHRH or CJC-1295 for broader body-recomp. Best choice for everyday GH modulation with minimal baggage.
Pick A or B?
Pick Tesamorelin if:
- Your main goal is eliminating visceral fat or recovering from HGH/insulin-induced "GH gut"
- You're managing NAFLD or want to drop liver fat—clinically validated
- You want a peptide with real, MRI-measured outcomes in humans
- Single daily convenience trumps pinging multiple doses
- You're stacking for a serious recomp phase post-bulk or post-cycle
Pick Ipamorelin if:
- You want the cleanest, most side-effect-free GHRP for sleep, recovery, or mild IGF-1 boost
- You're stacking with CJC-1295 for multi-pulse GH/IGF-1 modulation
- Fasted AM or pre-bed dosing fits your lifestyle (2–3x/day for optimal pulses)
- Joint or connective-tissue recovery is a priority
- You want a compound usable by both men and women, cycle after cycle, with minimal desensitization risk
