CJC-1295

History

CJC-1295 was developed as a modified GHRH analog with the objective of producing more prolonged stimulation of growth hormone secretion than native GHRH. Research into the compound investigated its ability to increase circulating growth hormone and IGF-1 concentrations following administration.

Clinical research demonstrated prolonged elevation of GH and IGF-1 following administration of the long-acting CJC-1295- DAC form. However, CJC-1295 did not progress to an approved therapeutic medicine and remains an investigational peptide.

NEXON

Chemical Structure

CJC-1295 is a modified synthetic peptide derived from the structure of GHRH.

The modifications are intended to:

• Improve metabolic stability
• Extend systemic exposure
• Increase interaction with circulating proteins
• Prolong stimulation of the GH/IGF-1 axis

The DAC-containing form incorporates a Drug Affinity Complex that contributes to its extended pharmacological profile.

NEXON

Pharmacology

CJC-1295 acts as an analog of growth hormone–releasing hormone, stimulating the GHRH receptor located primarily on somatotroph cells of the anterior pituitary gland.

Activation of this receptor promotes endogenous growth hormone secretion. Increased GH can subsequently stimulate production of IGF-1, particularly in the liver and other tissues.

The resulting pathway can be summarized as:

CJC-1295 → GHRH Receptor → Growth Hormone → IGF-1

NEXON

Mechanism of Action

The general mechanism involves:

• Subcutaneous administration
• Systemic peptide exposure
• Binding to GHRH receptors
• Activation of pituitary signaling
• Increased endogenous GH secretion
• Increased IGF-1 production
• Modulation of growth hormone–dependent metabolic processes

NEXON

Pharmacodynamics

CJC-1295 primarily influences:

• Growth hormone secretion • IGF-1 production • GH/IGF-1 axis activity • Pituitary endocrine signaling

NEXON

Pharmacokinetics

The pharmacokinetic characteristics of CJC-1295 depend substantially on the molecular form being studied.

The CJC-1295-DAC form was specifically designed to produce prolonged systemic exposure. Clinical research demonstrated a substantially extended pharmacological effect compared with native GHRH, with sustained increases in circulating GH and IGF-1.

The pharmacokinetic profile of non-DAC CJC-1295 is considerably shorter and should not be treated as interchangeable with the DAC form.

NEXON

Physiological Effects

CJC-1295 primarily influences physiology by stimulating endogenous growth hormone secretion through activation of the GHRH receptor. Increased GH secretion can subsequently elevate IGF-1 concentrations, producing downstream effects on protein metabolism, lipid utilization, connective-tissue turnover, bone physiology, and glucose regulation. This mechanism differs from direct administration of recombinant growth hormone because CJC-1295 acts upstream of GH production at the pituitary level.

The magnitude and duration of these effects depend on the molecular form, particularly whether the peptide incorporates the Drug Affinity Complex. Clinical research involving CJC-1295-DAC has demonstrated prolonged increases in GH and IGF-1 concentrations, but these endocrine changes should not automatically be interpreted as established improvements in muscle growth, athletic performance, or body composition.

NEXON

Clinical Applications

CJC-1295 has been investigated primarily as a potential means of stimulating the GH/IGF-1 axis. Research has examined its effects on growth hormone secretion and IGF-1 exposure, with potential relevance to conditions associated with inadequate GH activity.

However, CJC-1295 itself does not have an established approved therapeutic indication. Its clinical development has remained investigational, and the evidence available for medical treatment is substantially more limited than that for approved recombinant growth hormone products.

Safety Considerations

The use of anabolic-androgenic steroids may require consideration of cardiovascular, hematological, hepatic, endocrine, metabolic, and reproductive health.

Important safety considerations include:

• Cardiovascular health
• Blood pressure
• Hematological parameters
• Lipid profile
• Liver function
• Endocrine function
• Reproductive function
• Prostate health

The overall safety profile depends on the specific compound, formulation, concentration, duration of exposure, individual response, and patient characteristics. Appropriate medical evaluation and regular monitoring should be considered when clinically indicated.

Drug Interactions

A comprehensive interaction profile may not be established for every anabolic-androgenic steroid or formulation.

• Potential interactions or clinical considerations may exist with:
• Anticoagulants
• Antidiabetic medications
• Hepatotoxic medications
• Other anabolic-androgenic steroids
• Other hormonal therapies
• Drugs affecting lipid metabolism

The clinical significance of potential interactions depends on the specific compound, formulation, dosage, duration of exposure, concomitant medications, and individual patient characteristics. Appropriate medical evaluation should be considered when multiple medications or hormonal therapies are used concurrently.

Frequently Asked Questions

What is CJC-1295? CJC-1295 is a synthetic analog of growth hormone–releasing hormone (GHRH) that stimulates endogenous GH secretion.

Is CJC-1295 a steroid? No. It is a synthetic peptide.

Is CJC-1295 a SARM? No. Its primary target is the GHRH receptor, not the androgen receptor.

Is CJC-1295 oral or injectable? CJC-1295 is encountered as an injectable peptide, generally administered subcutaneously in research and clinical-study settings.

What is the difference between CJC-1295-DAC and non-DAC CJC-1295? The DAC form contains a Drug Affinity Complex designed to extend systemic exposure and prolong the pharmacological effect. The non-DAC form has a substantially shorter duration.

Does CJC-1295 directly contain growth hormone? No. CJC-1295 does not supply recombinant GH directly. It stimulates the body's own GH secretion through the GHRH receptor.
