Which one should you choose?

Tesamorelin is better for targeted visceral fat loss, while CJC-1295 is better for general anti-aging and recovery. Both are GHRH analogs. Tesamorelin is an FDA-approved formulation specifically designed to reduce visceral adipose tissue (hard belly fat) by creating massive, sharp spikes in GH that strongly trigger lipolysis. CJC-1295 provides a more moderate, sustained elevation of GH suitable for long-term use. Choose Tesamorelin if your primary goal is aggressive fat loss or reversing metabolic syndrome. Choose CJC-1295 if you want a cost-effective, long-term protocol for sleep, skin, and mild body recomposition. For pure fat loss, Tesamorelin is the premium default.
