Tirzexyl contains 5 mg of pharmaceutical-grade Tirzepatide in a 2 mL vial. This dual GLP-1 and GIP receptor agonist is Kalpa's answer to the growing demand for advanced weight loss peptides. Tirzexyl mimics natural incretin hormones to control appetite, slow digestion, and enhance insulin sensitivity.
Tirzepatide is best known under its prescription name Mounjaro. Kalpa's version—Tirzexyl—is designed for research and off-label applications focused on body recomposition, fat reduction, and improved metabolic health. Clinical studies, such as those reviewed here on PubMed, show it can outperform both GLP-1 monotherapy and traditional fat burners.
Most users begin at 2.5 mg per week and titrate up gradually to 10–15 mg per week. Tirzexyl is injected subcutaneously once weekly, typically in the abdomen or thigh. The long active life (~7 days) makes it extremely convenient.
For enhanced fat loss, Tirzexyl pairs well with Letroxyl (Letrozole) during cycles that risk estrogen buildup. It also complements Clomixyl for post-cycle therapy or metabolic support.
To boost thyroid function and support energy output, consider stacking with Thyroxyl (Liothyronine Sodium). For appetite control during cycles, Sildenaxyl can assist indirectly by managing blood flow and mood stability.
Tirzexyl contains the same active compound—Tirzepatide—as Mounjaro. Both act on GLP-1 and GIP receptors, but Tirzexyl is available without a prescription for research use.
When used responsibly, Tirzepatide has a favorable safety profile. Most users tolerate weekly injections well over extended cycles, especially with proper dosage titration.
