Tesamorelin
Tesamorelin is a synthetic peptide analogue of growth hormone–releasing hormone (GHRH). It works by stimulating the pituitary gland to increase the body’s natural production and pulsatile release of growth hormone, rather than supplying growth hormone directly. This supports more physiologically regulated hormone output.
Body Composition and Fat Metabolism
Tesamorelin has been studied for its effects on fat metabolism and body composition, particularly visceral fat. By increasing endogenous growth hormone levels, Tesamorelin supports lipolysis (fat breakdown) and improved metabolic signalling, making it commonly used in protocols focused on reducing stubborn or hormonally driven fat accumulation.
Muscle Preservation and Recovery
Growth hormone plays a key role in maintaining lean muscle mass and supporting tissue repair. Through its stimulation of growth hormone release, Tesamorelin may assist in preserving muscle mass, supporting recovery, and improving physical resilience, especially in individuals experiencing age-related hormonal decline.
Metabolic and Cardiovascular Health
Healthy growth hormone signalling is associated with improved insulin sensitivity, lipid metabolism, and cardiovascular markers. Tesamorelin’s ability to enhance endogenous growth hormone release may contribute to supporting metabolic health and overall cardiovascular risk profiles when used as part of a structured health program.
Cognitive Function and Wellbeing
Growth hormone and IGF-1 influence brain function, mood regulation, and cognitive performance. By supporting these pathways, Tesamorelin may contribute to improvements in mental clarity, focus, and overall sense of wellbeing, particularly in individuals with low growth hormone activity.
Sleep and Recovery Support
Growth hormone is primarily released during deep sleep. By enhancing natural growth hormone signalling, Tesamorelin may help support sleep quality, overnight recovery, and circadian hormone rhythms, which are critical for long-term health and performance.
Healthy Ageing Support
Growth hormone levels decline steadily with age, contributing to changes in body composition, energy levels, and recovery capacity. Tesamorelin is commonly used in healthy ageing and longevity-focused protocols to support hormonal pathways associated with vitality and metabolic health, without suppressing the body’s own hormone production.
Physiological and Regulated Action
Unlike exogenous growth hormone, Tesamorelin preserves the body’s natural feedback mechanisms. This helps reduce the risk of hormone suppression and supports a more controlled, physiologically aligned approach to growth hormone optimisation.
