CJC-1295
researchGrowth hormone secretagogue for anti-aging, body composition, and recovery
Overview
CJC-1295 is a synthetic analog of growth hormone-releasing hormone (GHRH) that stimulates the pituitary gland to increase natural growth hormone (GH) and IGF-1 production. Rather than introducing external growth hormone, it works with the body's own production pathways — making it one of the most widely used peptides for anti-aging, body composition improvement, enhanced recovery, and better sleep quality.
In Thailand, CJC-1295 is popular among bodybuilders, anti-aging enthusiasts, and biohackers. It is commonly combined with Ipamorelin, a complementary growth hormone-releasing peptide that acts through a separate receptor pathway. Several Thai clinics offer CJC-1295 as part of their peptide therapy and anti-aging programs, and it is readily available through local peptide vendors in both standalone and pre-blended CJC-1295/Ipamorelin formulations.
How It Works
GHRH receptor stimulation
CJC-1295 binds to GHRH receptors on pituitary cells, stimulating growth hormone synthesis and release. Four amino acid substitutions in the original GHRH sequence make it resistant to the enzyme DPP-4 that rapidly destroys natural GHRH, dramatically extending its active life.
Sustained GH and IGF-1 elevation
Human studies demonstrated that a single injection increases GH levels 2 to 10 times above baseline for 6+ days and IGF-1 levels 1.5 to 3 times for 9-11 days. With multiple doses, IGF-1 remains elevated for up to 28 days, indicating a cumulative effect.
Pituitary priming
CJC-1295 doesn't just trigger GH release — it increases GH mRNA and pituitary GH stores, essentially priming the gland to produce more growth hormone over time. Animal studies showed that daily CJC-1295 completely normalised growth, body composition, and lean mass in growth hormone-deficient models.
Synergy with Ipamorelin
CJC-1295 works through GHRH receptors while Ipamorelin works through ghrelin receptors — a completely separate pathway. Together, they produce synergistic GH release significantly greater than either compound alone. CJC-1295 primes the pituitary; Ipamorelin triggers the pulse.
Benefits & Uses
- Increased natural growth hormone: Sustained, dose-dependent elevation of GH and IGF-1 through the body's own production pathways
- Improved body composition: Enhanced lean muscle growth and reduced body fat, particularly visceral fat
- Better sleep quality: GHRH activity is directly linked to deeper slow-wave sleep — typically the first benefit users notice, often within 1-2 weeks
- Enhanced recovery: Faster healing from workouts, injuries, and surgical procedures through elevated GH-mediated tissue repair
- Anti-aging effects: GH and IGF-1 support skin elasticity, collagen production, and cellular repair processes that decline with age
- Fat metabolism: Growth hormone promotes lipolysis and fat oxidation, supporting body recomposition
Protocol Quick Reference
Side Effects
Common
- Water retention or bloating — temporary, usually resolves within 1-2 weeks
- Tingling or numbness in extremities
- Flushing or warmth after injection
- Increased appetite
- Vivid dreams — related to deeper sleep cycles
Less Common
- Headache
- Fatigue or lethargy during initial adaptation
- Mild joint stiffness from water retention
Serious
- Not recommended for individuals with active cancer — GH and IGF-1 can promote tumour growth
- Not recommended for those with uncontrolled diabetes or severe cardiovascular disease
- Potential immunogenicity — the body may develop antibodies against the peptide in some individuals
- Cardiovascular caution — potential for increased heart rate and transient vasodilatory reactions (flushing, warmth, temporary low blood pressure) particularly with the DAC version
Legal Status in Thailand
Available as a research peptide in Thailand. Not an approved pharmaceutical in any country.
Prescription: Not required from vendors. Clinics include it as part of supervised anti-aging and peptide therapy protocols.
Available from multiple Thai peptide vendors and offered at several clinics in Bangkok and Pattaya. Often sold as a pre-blended CJC-1295/Ipamorelin combination for convenience.

FAQ
What is the difference between CJC-1295 with DAC and without DAC?▼
The DAC (Drug Affinity Complex) version bonds to blood albumin, extending the half-life to 6-8 days and creating continuous GH elevation. Dosed once or twice weekly. The no-DAC version (also called Modified GRF 1-29) has a ~30-minute half-life and produces short, pulsatile GH release that better mimics natural patterns. Dosed daily. Most practitioners prefer no-DAC with Ipamorelin for a more physiological approach.
Why is CJC-1295 combined with Ipamorelin?▼
They work through completely different receptor systems — CJC-1295 mimics GHRH (priming the pituitary) while Ipamorelin mimics ghrelin (triggering the GH pulse). Together, the synergistic effect produces GH release significantly greater than either compound alone. Ipamorelin's selectivity also means no unwanted cortisol or prolactin elevation.
How long before I notice results?▼
Improved sleep quality is typically the first benefit noticed, often within 1-2 weeks. Enhanced recovery and energy follow within 2-4 weeks. Body composition changes (increased lean mass, reduced body fat) become measurable after 8-12 weeks of consistent use.
Can CJC-1295 replace HGH injections?▼
CJC-1295 stimulates natural GH production rather than introducing external growth hormone. The absolute GH levels achieved are lower than pharmaceutical HGH, but the approach is considered more physiological. For mild age-related GH decline, CJC-1295/Ipamorelin may be sufficient. For severe deficiency, prescription HGH may be necessary.
How much does CJC-1295 cost in Thailand?▼
CJC-1295 pricing in Thailand varies by form — standalone vials vs pre-blended CJC-1295/Ipamorelin combinations — and by source. Clinic-administered programs cost more but include medical supervision. Check vendor and clinic websites directly for current rates.
Should I take CJC-1295 on an empty stomach?▼
Yes. Food — particularly carbohydrates and fats — significantly blunts the GH response. Most protocols recommend injecting at least 2 hours after eating. Bedtime on an empty stomach is the most common approach, aligning with the natural GH peak during deep sleep.
