CJC-1295 + Ipamorelin is the most popular and effective peptide duo in natural growth hormone (GH) stimulation therapy. It is not synthetic HGH (human growth hormone), but a combination of two peptides that stimulate the pituitary gland to release GH in a physiological pulse rhythm, safely and sustainably elevating GH and IGF-1 levels according to age.
CJC-1295 is an analog of Growth Hormone-Releasing Hormone (GHRH), while Ipamorelin is a highly selective Growth Hormone Secretagogue (GHS).

STRUCTURE AND DETAILED MECHANISM OF ACTION
- CJC-1295 (commonly used in DAC or non-DAC form): A 30-amino acid peptide that mimics GHRH from the hypothalamus. It binds to the GHRH-R receptor on somatotroph cells in the pituitary gland, activating the Gs/cAMP signaling pathway → increasing GH synthesis and secretion.
- Ipamorelin: A 5-amino acid peptide that acts as a ghrelin mimetic. It binds to the ghrelin receptor (GHS-R1a), strongly and rapidly stimulating GH release without significantly increasing cortisol, prolactin, or ACTH (much more selective than GHRP-2 or GHRP-6).
When combined: Ipamorelin creates a strong and fast GH pulse (peak within 1 hour), while CJC-1295 prolongs and sustains the GH release. The synergistic effect increases GH levels by 3–10 times, sustainably raises IGF-1, and maintains the natural pulsatile rhythm of GH without shutting down the pituitary gland like exogenous HGH.
DIFFERENCE BETWEEN CJC-1295 WITH DAC AND NO DAC
- CJC-1295 with DAC (Drug Affinity Complex): Long half-life (5–8 days), provides prolonged and steady GH release. Ideal for those who prefer fewer injections (1–2 times per week). Strong cumulative effect and more sustained IGF-1 elevation. However, it may cause more water retention and is less “pulsatile” compared to natural patterns.
- CJC-1295 without DAC (also known as Mod GRF 1-29): Short half-life (about 30 minutes), requires multiple daily injections (2–3 times/day) to create a GH pulse pattern closest to natural physiology. Causes less water retention and is more flexible, but less convenient due to injection frequency.
Most users prefer the CJC with DAC + Ipamorelin blend for convenience, while the non-DAC version is better suited for those wanting to closely mimic the body’s natural GH rhythm.

MAIN BENEFITS OF CJC-1295 + IPAMORELIN
Based on research and real-world application:
- Muscle growth & recovery: Increases protein synthesis, supports lean muscle development, and accelerates post-workout recovery.
- Fat loss & body recomposition: Strongly promotes lipolysis, especially visceral and abdominal fat.
- Deeper sleep: Enhances slow-wave sleep, improving physical and mental recovery.
- Anti-aging & overall health: Boosts collagen production (skin, hair, nails), improves bone density, joint health, energy, and mood.
- Joint & injury support: Increases collagen synthesis and reduces inflammation.
- Enhanced vitality: Improves libido and endurance when stacked with other hormone peptides such as Kisspeptin.
CLINICAL EVIDENCE AND KEY STUDIES
- CJC-1295: Randomized, double-blind clinical trials (2006) showed that doses of 30–60 mcg/kg increased GH levels for many days, with IGF-1 rising 1.5–3 times and remaining elevated for 9–28 days. Safe in healthy individuals.
- Ipamorelin: Studies from 1999–2000 confirmed strong GH increase with rapid peaks and no significant effect on cortisol or prolactin.
- CJC + Ipamorelin combination: Mechanism data and widespread use in anti-aging medicine demonstrate powerful synergistic effects on elevating GH/IGF-1, improving body composition, sleep quality, and recovery.
DOSAGE GUIDELINES (Based on Research and Compounding Use)
- CJC-1295 with DAC: 1–2 mg subcutaneously 1–2 times per week.
- CJC-1295 without DAC: 100–200 mcg per injection, 2–3 times per day.
- Ipamorelin: 100–300 mcg per injection (commonly 200 mcg).
- Popular Blend: 100–200 mcg CJC + 100–300 mcg Ipamorelin injected subcutaneously before bedtime (5–7 nights per week). Start with low doses for the first 2–4 weeks, then adjust according to IGF-1 blood tests. Inject in the abdominal area. Typical cycle: 8–12 weeks on, 4–8 weeks off.
SPECIFIC STACKING DOSAGES
- With Kisspeptin (reproductive hormone balance + GH): Kisspeptin-10: 100–150 mcg in the morning, 2–3 times/week. CJC + Ipamorelin: 100–200 mcg blend before bed.
- With AOD9604 (strong fat loss + body recomposition): CJC + Ipamorelin: standard dose before bed. AOD9604: 300–500 mcg in the morning on an empty stomach.
- With BPC-157 (injury recovery, joints, gut): CJC + Ipamorelin: standard dose. BPC-157: 250–500 mcg/day (split 1–2 times).
- With TB-500 (soft tissue recovery): CJC + Ipamorelin: standard dose. TB-500: 2–5 mg/week (split into 2 doses).
General stacking advice:
- Do not mix in the same syringe.
- Administer GH peptides at night and Kisspeptin in the morning.
- Start with low doses and monitor IGF-1, glucose, and insulin after 4–6 weeks.
SIDE EFFECTS
CJC-1295 + Ipamorelin is considered safe at therapeutic doses:
- Common mild effects: redness/pain at injection site, facial flushing, transient headache, mild water retention, increased appetite (less than other GHRPs).
- Rare: initial fatigue, dizziness.
- Does not significantly increase cortisol or prolactin. No serious adverse events reported in short-term studies.
