Mod GRF 5 mg (CJC-1295 without DAC) – Peptide Hubs
Mod GRF 1-29, commonly referred to as CJC-1295 without DAC, is a short-acting growth hormone-releasing hormone (GHRH) analog. It has been modified to enhance stability while avoiding long-term GH elevation, offering a pulsatile GH release pattern more in line with natural secretion. Peptide Hubs supplies Mod GRF in a 5 mg lyophilized vial for scientific research on recovery, GH dynamics, and anti-aging protocols.
Mechanism of Action
Mod GRF acts on the anterior pituitary by stimulating GHRH receptors, promoting a natural pulse of growth hormone. Unlike its long-acting DAC version, it mimics the body's endogenous GH rhythm and is often paired with GHRP compounds like GHRP-2 or Ipamorelin to amplify the GH surge. It avoids constant GH elevation, reducing desensitization risks. For more, see this NIH paper on GHRH analogs.
Research Applications
- Growth hormone pulse stimulation studies
- Recovery and injury repair models
- Anti-aging and cellular rejuvenation research
- GH axis modulation and endocrine function experiments
Mod GRF is often used in conjunction with GHRP-6 or GHRP-2 for synergistic GH release. It may also be stacked with GHK Basic for tissue recovery or AOD 9604 for metabolic studies.
Suggested Experimental Use
- Dosage: 100–200 mcg per injection, 2–3 times daily
- Administration: Subcutaneous injection, often timed with GHRP administration
- Cycle Duration: 4–12 weeks in GH restoration protocols
Stacking Recommendations
- GHRP-2 – for amplified GH surge and pituitary stimulation
- DSIP – for sleep-dependent GH optimization and recovery
- GHK Basic – to support collagen synthesis and injury repair
- Semaglutide – in metabolic modulation and fat-loss studies
Safety & Legal Status
Mod GRF is sold strictly for laboratory research use only and is not FDA-approved. It has shown excellent tolerability with no aromatization, hepatotoxicity, or suppression of endogenous hormones. For trial listings, visit ClinicalTrials.gov.
Frequently Asked Questions
What is Mod GRF used for in research?
Mod GRF is studied for its role in stimulating growth hormone release, promoting recovery, and restoring natural GH rhythms in endocrine research models.
How is Mod GRF different from CJC-1295 with DAC?
Mod GRF is short-acting and mimics natural GH pulses, while CJC-1295 with DAC offers extended GH elevation. Mod GRF allows better physiological control.
Can Mod GRF be stacked with GHRPs?
Yes. Mod GRF is often stacked with GHRP-2, GHRP-6, or Ipamorelin to achieve synergistic GH release in experimental settings.
Is Mod GRF FDA-approved for human use?
No. Mod GRF is not FDA-approved and is strictly intended for research use only in preclinical studies and scientific models.
