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)

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

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).
