Tesofensine- Summary
- 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.
- 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.
