Side-by-side comparison of key properties, dosing, and research.

Fat Loss & Metabolic
HGH Fragment 176-191
Summary
Tesofensine is a triple monoamine reuptake inhibitor (TMRI) that blocks reuptake of serotonin, dopamine, and norepinephrine. Originally developed for Alzheimer's and Parkinson's disease, it was repurposed as a potent weight loss agent after clinical trials demonstrated substantial fat loss via appetite suppression and increased energy expenditure.
HGH Fragment 176-191 (also known as AOD-9604) is a stabilized, modified fragment of the human growth hormone molecule corresponding to amino acids 176–191 with an addition of a tyrosine residue at the N-terminus. It retains HGH's fat-burning properties without the anabolic, diabetogenic, or IGF-1-stimulating effects.

Key Benefits
  • Potent appetite suppression via triple monoamine reuptake inhibition
  • Significant weight loss (8-12% body weight in phase II trials at 0.5 mg)
  • Increases basal metabolic rate and energy expenditure
  • Reduces fat mass preferentially over lean mass
  • Potential cognitive benefit via dopaminergic and noradrenergic enhancement
  • Longer half-life than sibutramine allows once-daily dosing
  • Selective fat burning without anabolic side effects
  • Reduces visceral and subcutaneous fat
  • No insulin resistance or blood glucose disruption
  • Does not stimulate IGF-1
  • May support cartilage and bone repair (at higher doses)
  • No effect on growth or organ size
Side Effects
  • Elevated heart rate and blood pressure (sympathomimetic)
  • Dry mouth
  • Insomnia and sleep disturbances
  • Nausea
  • +4 more
  • Injection site irritation
  • Temporary lethargy
  • Headache (rare)
