CJC-1295 / Ipamorelin Dosage Guide: How Much Should You Take? (2026)

Key Takeaways

• Standard Dosage Range: Typically, CJC-1295 / Ipamorelin is administered subcutaneously, with common doses ranging from 300 mcg to 500 mcg per injection.
• Administration Method: The most frequent method is subcutaneous injection, known for its effective absorption and convenience.
• Typical Cycle Length: Treatment cycles usually last between 8 to 12 weeks, with breaks in between cycles to prevent desensitization.
• Regulatory Status: CJC-1295 / Ipamorelin is classified as a Category 1 compoundable peptide, meaning it can be legally compounded by licensed pharmacies.
• Medical Supervision: Due to potential side effects and dosage variability, administration should always be under medical supervision.

How CJC-1295 / Ipamorelin Works in the Body

CJC-1295 and Ipamorelin are both growth hormone secretagogues, which means they stimulate the pituitary gland to release more growth hormone. This dual action can lead to enhanced muscle growth, improved recovery, and potential anti-aging effects. The mechanism of action involves binding to specific receptors on the pituitary gland, which increases the secretion of growth hormone and subsequently insulin-like growth factor 1 (IGF-1).

CJC-1295 has a long half-life due to its ability to bind to albumin, extending its duration of action compared to other peptides. This characteristic allows for less frequent dosing. Ipamorelin, on the other hand, is known for its selectivity and minimal side effects, as it does not significantly increase cortisol or prolactin levels. Clinical studies such as PMID 41476424 highlight the efficacy and safety profile of these peptides when used responsibly.

"Therapeutic peptides like CJC-1295 and Ipamorelin have shown promising results in enhancing recovery and muscle growth by modulating key signaling pathways." — PMID 41490200

Standard CJC-1295 / Ipamorelin Dosage Ranges (By Form)

Subcutaneous Injection

• Dosage Range: 300 mcg to 500 mcg per injection.
• Frequency: Typically administered once daily.
• Bioavailability: Subcutaneous injections provide a high level of bioavailability, making this the most common form of administration.

Intramuscular Injection

• Dosage Range: Similar to subcutaneous, 300 mcg to 500 mcg.
• Frequency: Once daily, though some protocols suggest alternate days.
• Bioavailability: Comparable to subcutaneous, but may be less preferred due to injection discomfort.

Subcutaneous administration is favored due to its ease and patient comfort. The bioavailability of peptides in this form ensures effective absorption and utilization by the body.

CJC-1295 / Ipamorelin Dosage by Use Case

Anti-Aging

• Dosage Range: 300 mcg daily.
• Administration Method: Subcutaneous injection.
• Cycle Length: 12 weeks, with a 4-week break.
• Clinical Reference: Many clinics follow protocols that align with studies showing improvements in skin elasticity and vitality (PMID 41490200).

Muscle Growth

• Dosage Range: 500 mcg daily.
• Administration Method: Subcutaneous injection.
• Cycle Length: 8-10 weeks, followed by a break.
• Clinical Reference: Enhanced IGF-1 levels have been documented in protocols aimed at muscle hypertrophy.

Recovery Enhancement

• Dosage Range: 300-500 mcg depending on severity.
• Administration Method: Subcutaneous injection.
• Cycle Length: 8 weeks, with possible extension based on response.
• Clinical Reference: Protocols often cite improvements in recovery times post-surgery or injury (PMID 41476424).

How Long Should You Take CJC-1295 / Ipamorelin?

Typical cycles range from 8 to 12 weeks. During the initial weeks (1-4), patients often report increased energy and improved sleep. By weeks 6-8, muscle growth and recovery benefits may become more pronounced. After 12 weeks, a break is recommended to prevent receptor desensitization. Tapering off is generally not required, but clinical discretion is advised.

Administration Protocol: How to Take CJC-1295 / Ipamorelin

Injection Technique

• Needle Gauge: Use a 29-31 gauge insulin syringe.
• Injection Sites: Rotate sites to prevent tissue damage; common sites include the abdomen, thigh, or buttocks.
• Rotation Schedule: Change injection sites daily.

Storage and Reconstitution

• Storage: Keep vials refrigerated at 2-8°C; protect from light.
• Reconstitution: Use bacteriostatic water; inject slowly into the vial and swirl gently to mix. Reconstitution guide

Step-by-Step Process

1. Wash hands and prepare the injection site with an alcohol swab.
2. Draw the prescribed dose into the syringe.
3. Pinch the skin and insert the needle at a 45-degree angle.
4. Inject slowly and withdraw the needle.
5. Apply slight pressure with a clean swab.

• Poor Storage/Handling: Compromises peptide stability and effectiveness.

What the Evidence Does Not Show

While CJC-1295 / Ipamorelin has shown promise in various applications, long-term safety data is limited. Most studies focus on short-term outcomes, and there is a lack of large-scale human trials assessing prolonged use. Additionally, dose-response relationships are not fully understood, necessitating cautious application.
