CJC 1295 No DAC Ipamorelin CJC-1295 without DAC (also called Mod GRF 1-29) and Ipamorelin are synthetic peptides commonly stacked together in research and bodybuilding communities for their synergistic effects on growth hormone (GH) release. They mimic natural growth hormone-releasing hormone (GHRH) and growth hormone-releasing peptide (GHRP) pathways, leading to pulsatile GH secretion without the prolonged half-life of DAC versions. This stack is popular for fat loss, muscle growth, recovery, and anti-aging, but it’s not FDA-approved for human use—primarily researched in animals and used off-label. Key Mechanisms CJC-1295 No DAC (Mod GRF 1-29): A 29-amino-acid analog of GHRH. It binds to pituitary GHRH receptors, amplifying GH pulses. Half-life: ~30 minutes (short-acting, requires frequent dosing). Ipamorelin: A selective GHRP that stimulates ghrelin receptors, promoting GH release with minimal cortisol/prolactin spikes (unlike GHRP-6). Half-life: ~2 hours. Synergy: CJC amplifies the GH pulse initiated by Ipamorelin, mimicking natural physiology for 5-10x baseline GH levels per dose. Evidence: Studies (e.g., Teichman et al., 2006 in Endocrine Reviews) show GHRH analogs like CJC increase GH/IGF-1 by 2-10x. Ipamorelin trials (Gobbur et al., 2019) confirm clean GH elevation. Combo data from user logs and rodent studies (e.g., J Clin Endocrinol Metab, 2006) report elevated IGF-1 for weeks. Common Protocols (Research/Community Use) Aspect Details Dosage CJC: 100-200 mcg/dose<br>Ipamorelin: 100-300 mcg/dose<br>Ratio: 1:1 to 1:1.5 (e.g., 100 mcg each) Frequency 2-3x/day (e.g., morning, post-workout, bedtime) on empty stomach; 5-7 days/week Cycle 8-12 weeks on, 4 weeks off to avoid desensitization Administration Subcutaneous injection (abdomen/thigh). Reconstitute with bacteriostatic water (2-3ml per 2-5mg vial). Stacking Often with BPC-157/Tesamorelin for recovery; avoid with high-carb meals (blunts GH). Benefits (Supported by Research/User Reports) Muscle/Strength: ↑ IGF-1 promotes hypertrophy (e.g., 5-10% lean mass in 12-week studies). Fat Loss: GH enhances lipolysis (visceral fat ↓10-20%). Recovery/Sleep: Faster healing, deeper REM (anecdotal GH studies). Anti-Aging: Skin elasticity, bone density via IGF-1. Low Sides: Ipamorelin’s selectivity reduces hunger/cortisol vs. other GHRPs. Potential Side Effects & Risks Mild/Common Serious/Rare Water retention, numbness in hands, injection site redness Pituitary desensitization (long-term high-dose), insulin resistance, carpal tunnel Head rush/flushing (first doses) Theoretical cancer risk (GH/IGF-1 promotes cell growth—avoid if history) Mitigation: Start low (50 mcg), cycle off, monitor bloodwork (IGF-1, glucose). Not for under 21, pregnant, or cancer-prone. Sourcing & Legality Legal: Research peptides only (not for human consumption). Gray market from labs like Peptide Sciences—test for purity (HPLC/MS). Cost: 200-400. Purity Check: Third-party COAs essential; avoid underdosed fakes. Bloodwork Recommendations Baseline: IGF-1, GH, glucose, A1C. Mid-cycle: Check for ↑IGF-1 (200-400 ng/mL target).

GH peptides can interact with meds (e.g., insulin).
