The critical period for metabolic and body shape changes begins at 4-8 weeks. Continued growth hormone secretion accelerates fat breakdown, resulting in a significant reduction in abdominal fat. Subjects experienced an average waist circumference reduction of 2-3cm. When combined with resistance training, lean body mass can increase by 0.8-1.2kg, while skin elasticity improves and fine lines diminish, directly related to increased collagen synthesis.
Long-term, profound effects are visible after 12 weeks or more. Middle-aged and elderly users experience a 1%-1.5% increase in lumbar spine bone mass, delaying osteoporosis; adolescents with partial growth hormone deficiency who continue use for 6 months experience an increase in annual height growth rate of 2-3 cm.
Endocrinologists remind users that those with high basal growth hormone levels and good pituitary function will see faster results, while obese individuals may require up to 6 weeks to see effects. Blindly increasing the dosage can easily cause headaches; regular monitoring of insulin-like growth factor-1 levels and proper lifestyle adjustments are necessary for optimal results.
