Understanding where in the GH axis each compound intervenes is fundamental to research design. QSC Peptides offers compounds at every level — from hypothalamic GHRH analogs to direct somatropin to downstream IGF-1 LR3.
| Compound | Class | Axis Entry Point | Target Receptor | Bypasses Pituitary? | QSC Peptides Price |

| CJC-1295 (No DAC) | GHRH Analog | Anterior pituitary | GHRHR | No — stimulates pituitary | From $230 |
| CJC-1295 (With DAC) | GHRH Analog (long) | Anterior pituitary | GHRHR | No — sustained pituitary | From $290 |
| Sermorelin | GHRH 1-29 | Anterior pituitary | GHRHR | No — stimulates pituitary | From $220 |
| Tesamorelin | Enhanced GHRH | Anterior pituitary | GHRHR | No — stimulates pituitary | From $240 |
| Ipamorelin | GH Secretagogue | Pituitary + Hypothalamus | GHSR-1a | No — amplifies pulse | From $190 |
| GHRP-2 / GHRP-6 | GH Secretagogue | Pituitary + Hypothalamus | GHSR-1a | No — amplifies pulse | From $180 |
| IGF-1 LR3 | IGF-1 Analog | Peripheral tissues (IGF-1R) | IGF-1R | Yes — bypasses fully | From $200 |
| HGH Frag 176-191 | Lipolytic fragment | Adipocytes (HSL) | Lipolytic pathway | Yes — bypasses fully | From $220 |
Direct somatropin from QSC Peptides completely bypasses the hypothalamic-pituitary axis. Use it when:
GHRH analogs stimulate the pituitary to release endogenous GH. Use them when:
GH secretagogues act on GHSR-1a to amplify GH pulses. Use them when:
QSC Peptides Tip: For comprehensive GH axis research, QSC Peptides offers compounds at every level — direct HGH (10–36 IU vials), GHRH analogs (CJC-1295, Sermorelin, Tesamorelin), GH secretagogues (Ipamorelin, GHRP-2, GHRP-6, Hexarelin), and downstream effectors (IGF-1 LR3, HGH Fragment 176-191).
