Ipamorelin + CJC-1295 Protocol Guide: The Physician-Supervised Approach to Growth Hormone Optimization
Ipamorelin and CJC-1295 are the most widely prescribed growth hormone secretagogue (GHS) stack in peptide therapy. Together, they stimulate your body's natural growth hormone production for improved body composition, recovery, sleep quality, and anti-aging benefits — without the risks of exogenous HGH.
Protocol Quick Reference
Who Is This Protocol For?
Growth hormone production peaks in your twenties and declines approximately 14% per decade after age 30. By age 60, most adults produce less than half the GH they did at 25. This protocol is designed for individuals who want to restore more youthful GH pulsatility without using synthetic HGH.
- Adults 30+ with declining body composition — increased abdominal fat, reduced lean mass, slower metabolism despite consistent training and nutrition
- Athletes seeking enhanced recovery — faster repair between training sessions, improved sleep quality, and reduced injury downtime
- Individuals with poor sleep quality — GH is released primarily during deep sleep; secretagogues amplify this natural pulse
- Those pursuing anti-aging benefits — improved skin elasticity, hair quality, cognitive function, and energy levels
- Post-injury or post-surgical patients — GH accelerates tissue repair and collagen synthesis
- Anyone with documented low IGF-1 levels — your Hatter Labs physician will assess this with baseline labs
This protocol is not appropriate for individuals with active cancer (GH can stimulate tumor growth), uncontrolled diabetes, active retinopathy, or hypersensitivity to either peptide. Individuals with a history of pituitary disorders require specialized evaluation.
How It Works: Mechanism of Action
Ipamorelin and CJC-1295 work through complementary mechanisms to stimulate natural GH release from the pituitary gland. Understanding why they are used together requires understanding their individual roles.
Ipamorelin: The Selective GH Secretagogue
- Ghrelin receptor agonist (GHS-R1a): Ipamorelin mimics the hunger hormone ghrelin at the pituitary, triggering GH release. However, unlike other ghrelin mimetics (like GHRP-6), Ipamorelin is highly selective — it stimulates GH without significantly increasing cortisol, prolactin, or appetite.
- Dose-dependent GH pulse: Ipamorelin produces a GH pulse proportional to the dose, giving physicians fine control over the magnitude of stimulation.
- Preserves natural pulsatility: Unlike exogenous HGH (which provides a flat, unnatural elevation), Ipamorelin triggers a pulse-and-fade pattern that mimics youthful physiology.
CJC-1295 (no DAC): The GHRH Analog
- Growth hormone releasing hormone (GHRH) analog: CJC-1295 mimics the hypothalamic signal that tells the pituitary to release GH. It amplifies the magnitude and duration of each GH pulse.
- Synergy with Ipamorelin: GHRH and ghrelin act on different receptors at the pituitary. Combining them produces a GH release that is significantly greater than either alone — clinical data suggests 3-5x greater peak GH when used together.
- No DAC variant preferred: CJC-1295 without DAC (Drug Affinity Complex) has a shorter half-life, producing discrete GH pulses rather than sustained elevation. This is considered safer and more physiologic for long-term use.
Why This Stack Over HGH: Exogenous HGH replaces your body's natural production and can suppress your pituitary over time. The Ipamorelin/CJC-1295 stack stimulates your own pituitary to produce and release GH naturally. This preserves the body's feedback mechanisms, produces physiologic pulsatile release, and carries a substantially lower risk profile than synthetic HGH.
Detailed Protocol
The standard protocol uses combined injections 2-3 times daily, with timing aligned to maximize natural GH release patterns. The most important injection is the evening/bedtime dose, which amplifies the large nocturnal GH pulse.
| Parameter | Standard Protocol | Aggressive Protocol |
|---|---|---|
| Ipamorelin Dose | 100-200 mcg per injection | 200-300 mcg per injection |
| CJC-1295 Dose | 100 mcg per injection | 100-200 mcg per injection |
| Frequency | 2x daily (morning + bedtime) | 3x daily (morning, post-workout, bedtime) |
| Timing | Fasted morning + 30 min before bed | Fasted AM + post-training + 30 min before bed |
| Duration | 8-12 weeks | 8-12 weeks |
| Off-Cycle | 4 weeks off between cycles | 4 weeks off between cycles |
| Administration | Subcutaneous injection (abdomen) | Subcutaneous injection (abdomen) |
| Food Timing | Inject on empty stomach; wait 20-30 min before eating | Same — carbs/fat blunt GH release |
Personalization Note: Dosing is adjusted based on your baseline IGF-1 levels, body composition goals, age, and GH response. Hatter Labs physicians start conservatively and titrate up based on lab results and symptom response. IGF-1 is monitored at 4-week intervals to ensure levels remain in the optimal range without exceeding safe thresholds.
Critical Timing Note: GH release is blunted by insulin. Always inject on an empty stomach and avoid eating (especially carbohydrates and fats) for at least 20-30 minutes after injection. The bedtime dose is most effective when dinner is finished 2-3 hours before injection.
What to Expect: Results Timeline

Potential Side Effects
The Ipamorelin/CJC-1295 stack is considered one of the safest GH-stimulating protocols because Ipamorelin is highly selective and does not significantly raise cortisol or prolactin. However, side effects can occur:
Common (mild, usually transient)
- Water retention and mild bloating, particularly in the first 2-3 weeks (GH-related)
- Tingling or numbness in hands/fingers (paresthesia) — indicates GH is elevated; typically resolves with dose adjustment
- Increased hunger, especially with higher Ipamorelin doses
- Injection site redness or irritation
- Vivid dreams or disrupted sleep initially (paradoxical; usually stabilizes)
- Mild headache during the first week
Uncommon (report to your physician)
- Persistent joint pain or carpal tunnel symptoms (indicates IGF-1 may be too high)
- Elevated fasting blood glucose (GH can reduce insulin sensitivity)
- Significant water retention not resolving after 3 weeks
- Any signs of gynecomastia (extremely rare with Ipamorelin but possible)
Safety Note: Regular IGF-1 monitoring is essential throughout this protocol. Hatter Labs checks IGF-1 at baseline, 4 weeks, and end of cycle. If IGF-1 exceeds the target range, the dose is reduced. Fasting glucose is also monitored, as GH secretagogues can affect insulin sensitivity in susceptible individuals. This is why physician supervision is not optional for this protocol.
Stacking Options
The Ipamorelin/CJC-1295 combination is already a stack, but it can be enhanced with additional peptides for specific goals.
+ Tesamorelin (Enhanced Fat Loss)
Tesamorelin is an FDA-approved GHRH analog specifically effective at reducing visceral abdominal fat. Adding it to the Ipamorelin/CJC-1295 stack amplifies GH-mediated lipolysis, particularly targeting the stubborn midsection fat that is most metabolically dangerous. This is the premium body composition protocol.
+ BPC-157/TB-500 (Recovery Stack)
For athletes or individuals recovering from injury, adding BPC-157 and/or TB-500 to the GH secretagogue stack creates a comprehensive recovery protocol. GH supports anabolic repair while the healing peptides address tissue-specific inflammation and regeneration.
+ MK-677 (Oral GH Secretagogue)
MK-677 (Ibutamoren) is an oral GH secretagogue that provides sustained baseline GH elevation. Some physicians add it during off-cycles to maintain a modest GH benefit without injections. Requires monitoring due to effects on appetite and blood glucose.
