Best Peptides for Fat Loss
Fat loss peptides target adipose tissue through direct lipolysis, metabolic rate acceleration, or GH-mediated fat oxidation. These compounds offer targeted fat reduction without the muscle-wasting effects of caloric restriction alone.

AOD-9604
ResearchFat LossA modified fragment of human growth hormone isolated to replicate fat-burning capability without altering IGF-1 levels or causing insulin resistance.
MOTS-c
ResearchMitochondrialA mitochondrial-derived peptide dubbed an 'exercise mimetic' that reverses age-related insulin resistance and enhances fat oxidation even in sedentary individuals.
HGH Fragment 176-191
ResearchFat LossAn isolated C-terminal fragment of human growth hormone engineered to deliver pure fat-burning without growth-promoting or diabetogenic effects.
5-Amino-1MQ
ResearchMitochondrialA small-molecule NNMT inhibitor that disrupts fat storage at the cellular level, reversing diet-induced metabolic slowdown and shrinking fat cells.
Adipotide
ResearchFat LossAn aggressive peptidomimetic that eradicates white fat by destroying the blood supply feeding fat cells. Carries severe renal toxicity risk.
AICAR
ResearchMitochondrialAn AMPK activator studied for endurance enhancement and metabolic effects. Sometimes called an exercise-in-a-pill compound.
Thyreogen
ResearchBioregulatorA Cytomax bioregulator for thyroid regeneration, preferred over synthetic T4/T3 for resolving age-related hypothyroidism.
