Tesamorelin for Men Over 40: Fat Loss vs Growth Hormone Comparison
Tesamorelin 2mg daily GHRH receptor agonist. Stimulates endogenous pulsatile GH release 15–18% reduction in VAT (Phase 3 data) High. Preserves nitrogen balance and amino acid uptake $400–$700 (research-grade compounded) Best for men over 40 targeting visceral

- Tesamorelin 2mg daily
- GHRH receptor agonist. Stimulates endogenous pulsatile GH release
- 15–18% reduction in VAT (Phase 3 data)
- High. Preserves nitrogen balance and amino acid uptake
- $400–$700 (research-grade compounded)
- Best for men over 40 targeting visceral fat without exogenous GH exposure. Mimics natural physiology most closely
- Recombinant GH (somatropin)
- Direct GH replacement. Bypasses pituitary signalling
- 10–15% VAT reduction at 2–4 IU daily
- Very high. Direct anabolic effect on muscle tissue
- $800–$1,500 (prescription required)
- More potent for lean mass gain but suppresses endogenous GH production. Requires careful cycling and may increase insulin resistance
- Ipamorelin + CJC-1295
- Ghrelin mimetic + GHRH analogue. Dual stimulation of GH release
- 8–12% VAT reduction (observational data, not Phase 3)
- Moderate. Preserves muscle but less pronounced than direct GH
- $250–$500
- Lower-cost peptide stack with moderate efficacy. Useful for men who want GH support without committing to daily tesamorelin injections
- Caloric restriction alone
- Energy deficit forces lipolysis across all fat depots
- 5–8% VAT reduction (highly variable, often regained)
- Low. Muscle loss common without resistance training
- $0
- Least effective for visceral fat specifically. Caloric restriction reduces subcutaneous fat preferentially and triggers metabolic adaptation
- Metformin + lifestyle intervention
- Improves insulin sensitivity, reduces hepatic glucose output
- 3–6% VAT reduction over 12 months
- Minimal direct effect on lean mass
- $10–$30
- Adjunct strategy for metabolic health but insufficient as monotherapy for meaningful VAT reduction in men over 40
