| Category | Growth Factors | Growth Factors |
| Standard Dose | Research indicates 250-300 mcg daily via subcutaneous injection, administered in the morning on an empty stomach. | Research indicates 1-2 IU daily for anti-aging and general optimization. 2-4 IU daily for body composition. 4-8+ IU daily in clinical GH deficiency (physician-supervised only). |
| Timing | Morning administration on empty stomach, at least 30 minutes before eating. Fasted state enhances lipolytic effect. | Bedtime injection (mimics natural nocturnal GH surge) or morning fasted. Split dosing (AM + pre-bed) for higher doses. Always on empty stomach — carbohydrates blunt GH action. |
| Cycle Duration | 12-20 week cycles. | Continuous use is common in anti-aging protocols. 6-12 month minimum for full benefits. Clinical GHD treatment is typically lifelong. |

AOD-9604 is a synthetic 16-amino acid fragment (residues 176-191) of the C-terminal domain of human growth hormone with a tyrosine substitution at the N-terminus. It selectively stimulates lipolysis by upregulating beta-3 adrenergic receptors in adipose tissue while inhibiting lipogenesis. It modulates lipid and glucose metabolism through beta-adrenergic and AMPK-related pathways without influencing IGF-1 activity, growth, or insulin sensitivity — retaining GH's fat-burning properties without its growth-promoting effects.

Human Growth Hormone (somatropin) is a 191-amino acid single-chain polypeptide produced by anterior pituitary somatotrophs. It binds the GH receptor (GHR), activating JAK2-STAT5 signaling and MAP kinase pathways. Systemically, HGH upregulates hepatic IGF-1 production, which mediates most of its anabolic effects through IGF-1R/PI3K/Akt/mTOR-driven protein synthesis. Direct GH effects include lipolysis activation, insulin antagonism, chondrocyte/osteoblast stimulation, and enhanced collagen synthesis. Effects are divided into direct (lipolysis, insulin antagonism) and indirect (IGF-1-mediated growth and anabolism).
Research indicates 1-2 IU daily for anti-aging and general optimization. 2-4 IU daily for body composition. 4-8+ IU daily in clinical GH deficiency (physician-supervised only).
