AOD-9604

Also known as Anti-Obesity Drug-9604, hGH Fragment 176-191, AOD9604

A fragment peptide studied for fat metabolism support

AOD-9604 is a modified fragment of human growth hormone being studied for its potential role in supporting fat metabolism and body composition, without the broader growth-related effects of full-length growth hormone.

How It Works

AOD-9604 mimics a specific fat-related region of the natural growth hormone molecule. By engaging pathways involved in how fat cells release and store energy, it is being studied for its potential to support the breakdown of stored fat while discouraging new fat formation, without the broader hormonal effects of full growth hormone.

The Science & Mechanism

AOD-9604 is a synthetic peptide based on the C-terminal region of human growth hormone (amino acids 176-191), with an added tyrosine residue at the N-terminus intended to improve stability. This fragment corresponds to the portion of the growth hormone molecule thought to carry its lipid-metabolizing signal. In preclinical models it appears to stimulate lipolysis (the breakdown of stored fat) and inhibit lipogenesis (the formation of new fat). Some early research explored whether it influences beta-3 adrenergic pathways in adipose tissue, though its precise mechanism is not fully established and later studies suggest it may act independently of beta-3 adrenergic receptors. In available studies it does not appear to meaningfully raise circulating IGF-1 or affect blood glucose the way intact growth hormone can. Its mechanism remains an area of ongoing investigation.

Potential Benefits

  • May support fat metabolism and lipolysis
  • May support body composition goals
  • May complement a structured metabolic protocol
  • Being studied for effects on adipose tissue without growth-hormone-like IGF-1 elevation
  • May support energy utilization from stored fat

Who It May Be Best Suited For

  • Individuals focused on metabolic and body composition optimization
  • Those exploring fat-metabolism support without growth-hormone-level signaling
  • Clients pairing peptide therapy with nutrition and training under guidance

Important Considerations

AOD-9604 is offered strictly as educational, physician-guided content and is not a weight-loss drug or a substitute for nutrition, training, and lifestyle foundations. It is not an FDA-approved treatment for obesity or any medical condition. Individual responses vary, and suitability is always assessed and personalized 1:1 by Dr. Rob. It is best considered as one part of a comprehensive metabolic strategy rather than a standalone solution.
