CJC-1295
CJC-1295 (No DAC). A tetrasubstituted GHRH analog with four amino acid modifications that solve the primary limitation of native GHRH: enzymatic destruction before the signal reaches its target.
Clinician-prescribed. Ships from a licensed U.S. pharmacy.
Four Substitutions. One Problem Solved.
Native GHRH arrives at the pituitary, activates the receptor, and is destroyed almost immediately. DPP-IV cleaves it within minutes. The signal is real but too short to produce meaningful GH output. Sermorelin has the same problem at a slightly longer timescale. CJC-1295 solves this with four targeted amino acid swaps. Each modification protects a specific enzymatic vulnerability without changing how the peptide binds its receptor or what happens after it does. The half-life extends from 5-10 minutes to approximately 30 minutes. The signal lasts long enough to matter.
The Evidence
Conventional GH Approaches vs. CJC-1295 (Modified GRF 1-29, No DAC)
| Conventional GH Approaches | CJC-1295 (Modified GRF 1-29, No DAC) |
|---|---|
| Native GHRH destroyed by DPP-IV within minutes of release | Four amino acid substitutions protect against all major cleavage sites |
| Sermorelin effective but short-lived (5-10 minute half-life) | 30-minute effective half-life, 3-6x longer than native GHRH |
| Exogenous HGH bypasses pituitary, flat non-pulsatile elevation | Pulsatile release through intact pituitary feedback loop |
| CJC-1295 with DAC produces continuous GH elevation, blunting pulsatility | Without DAC, preserves natural pulse pattern and somatostatin regulation |
| MK-677 oral secretagogue causes appetite, water retention, insulin effects | No oral side effects, no appetite stimulation, no insulin disruption |
| Single-receptor approaches limit total GH output ceiling | Pairs with Ipamorelin for dual-receptor synergistic activation |

Important Information About Compounded Injectables
- Compounded medications are not reviewed or approved by the FDA and do not undergo the same pre-market evaluation as FDA-approved drugs.
- IVUSE peptide injections are prepared using peptide ingredients by FDA-registered, U.S.-licensed 503A & 503B compounding pharmacies, where available and clinically appropriate.
- Availability and formulation may vary based on state regulations, evolving clinical guidance, and pharmacy partners.
All prescriptions, treatment decisions, and care plans are made independently by licensed healthcare providers using their professional judgment. Images and product depictions are for illustration only; actual packaging and supplies may vary.
*If you are interested in a prescription product, IVUSE will coordinate a telehealth visit with a licensed medical provider who will determine whether you are an appropriate candidate based on your health profile and current standards of care. If approved, a prescription will be issued and filled by one of our partner pharmacies. All prescriptions are subject to provider discretion and clinical appropriateness.
