Not intended for human consumption. - [Tess-10](https://getleanlabs.com/product/tesamorelin/): Research Use Notice For research use only. - [CJIPA-10](https://getleanlabs.com/product/cjc-1295-ipamorelin/): CJC-1295 and Ipamorelin are frequently paired in research due to their complementary mechanisms of action within the growth hormone (GH) axis. Together, they provide a coordinated approach to stimulating endogenous GH release through both hypothalamic and pituitary signaling pathways. CJC-1295, a growth hormone releasing hormone (GHRH) analog, works by promoting sustained stimulation of GH release, while Ipamorelin, a selective growth hormone secretagogue, triggers pulsatile GH secretion through ghrelin receptor activation. The combination allows researchers to investigate both sustained and episodic GH signaling within a single model. This dual-pathway approach makes the blend a widely used option in studies focused on recovery […] - [BacW](https://getleanlabs.com/product/bacteriostatic-water/): Research Use Notice For research use only.
