AOD9604

AOD-9604 – 5mg (Lyophilized Peptide) – For Research Use Only

AOD-9604 is a modified fragment of human growth hormone (HGH), specifically amino acids 176–191, developed for its potential role in fat metabolism and lipolysis research. Unlike full-sequence HGH, AOD-9604 is studied for its ability to promote fat breakdown without influencing blood sugar or IGF-1 levels, making it a focus of metabolic and weight management studies.

Research has explored its effects on adipose tissue, body composition, and metabolic rate regulation.

Product Details:

  • Peptide: AOD-9604 (HGH Fragment 176–191)

  • Purity: >98%

  • Form: Lyophilized powder

  • Quantity: 5mg per vial

  • Storage: Store at -4°F (-20°C). After reconstitution, refrigerate at 36–46°F (2–8°C) and use within 30 days.

  • Grade: For research purposes only. Not for human consumption, therapeutic, or diagnostic use.

Potential Research Applications:

  • Fat metabolism and lipolysis studies

  • Obesity and weight management research models

  • Adipose tissue regulation investigations

  • Metabolic health and energy balance research

AOD9604 peptide​ Details

AOD-9604 is a synthetic fragment corresponding to amino acids 177–191 of the human growth hormone (hGH) molecule — specifically the C-terminal region long associated with hGH's lipolytic (fat-metabolizing) activity, isolated without the region responsible for hGH's growth-promoting and insulin-desensitizing effects. This targeted design was the original rationale behind AOD-9604's development: researchers sought a compound that could reproduce hGH's fat-metabolism signaling — stimulating lipolysis in adipocytes and inhibiting lipogenesis — without triggering the broader anabolic and glucose-regulatory effects of full-length hGH. Clinical-stage trials (conducted by Metabolic Pharmaceuticals/Phosphagenics) examined AOD-9604 specifically for obesity and metabolic research applications, and it remains a frequently cited compound in fat-metabolism and adipose-tissue signaling studies, where it is investigated for its interaction with beta-3 adrenergic receptor pathways involved in lipolysis.

Research

AOD9604 peptide​ Scientific Research

1. AOD9604 and Obesity Models

AOD9604 was originally developed as an hGH analogue with targeted activity against excess adipose tissue. Preclinical and early-phase clinical investigations have examined its impact on body weight and fat mass:

  • In obese animal models, AOD9604 has been associated with reductions in body weight and fat mass over defined treatment periods.
  • Research indicates that AOD9604 can promote fat loss even in models lacking functional β3-adrenergic receptors, suggesting that additional mechanisms beyond classical adrenergic signaling are involved.
  • These findings have led to hypotheses that AOD9604 may influence apoptosis pathways in white adipose tissue or engage other fat-specific signaling cascades.

In a human research context, AOD9604 has been evaluated in controlled settings to observe its impact on weight-related endpoints and the sustainability of these effects over several weeks. The data are interpreted as mechanistic insights rather than as evidence of established therapeutic efficacy.

2. AOD9604, Joint Function, and Cartilage Research

Beyond adipose-focused studies, AOD9604 has been examined in experimental models of joint disease and osteoarthritis:

  • In rat models, intra-articular administration of AOD9604 has been explored for its effects on pain-related behavior, joint function, and structural parameters.
  • Some studies have reported improvements in gross clinical assessment and microscopic cartilage features when AOD9604 is combined with existing interventions.
  • These observations suggest that AOD9604 may interact with cartilage metabolism and joint remodeling pathways, making it a candidate tool for investigating chondrocyte activity, matrix turnover, and osteoarthritic progression in preclinical models.

The mechanisms underlying these potential synergistic effects remain under active investigation and may involve growth factor signaling, extracellular matrix synthesis, or anti-catabolic pathways in joint tissues.

3. AOD9604 and Cardiometabolic Research

Because excess adiposity is closely linked to cardiovascular risk, AOD9604 has also been studied in the broader context of cardiometabolic health:

  • Fat reduction alone can influence cardiovascular biomarkers, but some studies suggest that AOD9604 may have effects on metabolic parameters that are not solely explained by weight loss.
  • Researchers are exploring whether secondary pathways engaged by AOD9604—particularly those independent of β3-adrenergic receptor activation—may modulate lipid profiles, inflammatory markers, or other risk factors in animal models.
  • Comparisons have been drawn to other agents that improve metabolic status without directly causing weight loss, supporting continued interest in AOD9604 as a mechanistic research tool.

These investigations aim to clarify how specific hGH-derived fragments can selectively impact metabolic networks and cardiovascular-related endpoints.

Storage & Handling

All peptides are supplied as sterile, lyophilized powder and are stable when handled correctly.

  • On arrival: Store vials in a cool, dry place away from heat and direct sunlight.
  • Long-term (powder): For optimal longevity, keep lyophilized peptides refrigerated to help maintain integrity.
  • After reconstitution: Use an appropriate research diluent (for example, BAC water). Store the reconstituted solution in the refrigerator and use within 20–30 days for best stability.

Note: Minimize exposure to moisture and repeated freeze–thaw cycles. Follow your institution's safety procedures when handling research materials.
