Verdict
HGH (Somatropin) wins for direct, predictable increases in IGF-1, global recomposition (lean mass gain + low-level fat loss), skin and tendon quality improvements, and overall potency for physique changes. More established dosing protocols and easier to quantify/verify with bloodwork.
Tesamorelin wins for targeted visceral fat and liver fat reduction, lower risk of soft tissue side effects (edema, carpal tunnel), preservation of endogenous GH rhythm, and a much tighter safety profile for long-term metabolic health. Superior for users wanting VAT loss without the full spectrum of HGH effects or side effects.
Pick A or B?
Pick HGH (Somatropin) if:
- You want broad-spectrum recomposition: subcutaneous fat loss, lean mass gain, skin thickening, and connective tissue support
- Prioritizing muscle, skin, or anti-aging effects rather than only visceral fat
- You need a predictable boost to IGF-1 for synergy with TRT, AAS, or other stack compounds
- You have access to verified, high-quality HGH kits and reliable IGF-1 lab monitoring
- Willing to navigate higher cost and side effect risk for wider results
Pick Tesamorelin if:
- Reducing stubborn visceral adipose tissue or hepatic fat is your primary goal (especially for controlling 'GH gut' or NAFLD)
- You want lower water retention, arthralgia, and carpal tunnel risk
- You prefer stimulating your own GH axis for a more physiologic, pulsatile release
- Long-term metabolic health and safety are higher priorities than maxing out physique gains
- You want to preserve more of your natural hormonal rhythm (less risk of suppressing endogenous GH pulses)
