What Is Ipamorelin/CJC-1295?
Ipamorelin and CJC-1295 is a compounded peptide combination that stimulates your pituitary gland to release more growth hormone (GH). Ipamorelin triggers fast GH pulses that mimic your body's natural rhythm, while CJC-1295 with DAC keeps those levels elevated for days.1
This isn't an FDA-approved product. It's only available through compounding pharmacies, typically prescribed at TRT and longevity clinics for men dealing with fatigue, muscle loss, poor recovery, and other age-related decline symptoms.2
You inject it subcutaneously at home, usually before bed. Most protocols run 5-7 nights per week.
The combination addresses symptoms that testosterone replacement alone may not fully resolve — particularly recovery time, body composition, and sleep quality. Many clinics position it as an add-on to TRT rather than a standalone therapy.
Ipamorelin/CJC-1295 at a Glance
A compounded peptide combination that stimulates natural growth hormone production through complementary pituitary pathways.
Best for men seeking recovery, body composition, and sleep improvements alongside TRT, willing to self-inject nightly.
- Mechanism: Dual GH stimulation — pulsatile (Ipamorelin) plus sustained (CJC-1295)
- Dosing: 200-400mcg total subcutaneous injection, nightly before bed
- Safety: Monitor IGF-1 quarterly; contraindicated with active cancer or pituitary tumors
- Cost: $200-400/month cash pay; not covered by insurance
How This Peptide Combination Works
Your pituitary gland produces growth hormone in pulses throughout the day, with the biggest surge happening during deep sleep. This peptide combo hijacks that system at two different points.
Ipamorelin acts like ghrelin — the hunger hormone that also triggers GH release. It binds to growth hormone secretagogue receptors (GHS-R1a) on your pituitary cells and blocks somatostatin, the hormone that normally shuts down GH production.3 The result is a sharp GH pulse within minutes of injection, lasting about 2 hours.
CJC-1295 takes a different route. It mimics growth hormone-releasing hormone (GHRH), the signal your hypothalamus uses to tell the pituitary to make GH. The DAC modification — Drug Affinity Complex — makes it bind to albumin in your blood, extending its half-life to 6-8 days.1
That extended action creates a sustained baseline GH elevation. One dose raises GH levels 2-10x for at least 6 days and keeps IGF-1 elevated for 9-11 days.1
The combination gives you both: Ipamorelin's immediate pulses that feel natural, plus CJC-1295's steady background stimulation. You're not injecting GH directly — you're nudging your body to make more of its own.
Unlike older GH secretagogues like GHRP-6, Ipamorelin doesn't spike cortisol or prolactin — it's selective for GH.2 And unlike direct GH injections, you're working within your body's regulatory feedback loops, which theoretically reduces the risk of supraphysiologic side effects.
Most users report noticing better sleep quality within days, with body composition changes becoming visible after 4-8 weeks of consistent use.4
Somatostatin is an inhibitory hormone that suppresses growth hormone production in the pituitary gland. Peptides like Ipamorelin work by blocking somatostatin's effects, allowing GH release to occur.
IGF-1 (Insulin-Like Growth Factor-1) is a hormone produced primarily by the liver in response to growth hormone stimulation. It mediates many of GH's anabolic effects on muscle, bone, and metabolic health.
Supraphysiologic refers to hormone levels that exceed the body's normal physiological range. Direct GH injections can cause supraphysiologic levels, whereas peptide secretagogues work within natural feedback mechanisms to minimize this risk.
Dosing & Administration Protocol
You'll inject this subcutaneously — into the fat layer under your skin, usually in your abdomen or thigh. Most clinics prescribe it as a single nightly dose, typically 30-60 minutes before bed to align with your natural GH surge during deep sleep.5
Standard starting dose is 100 mcg CJC-1295 plus 200-300 mcg Ipamorelin per injection. Some protocols titrate up to 300-500 mcg total based on IGF-1 response and symptom improvement.4
| Parameter | Standard Protocol | Clinical Notes |
|---|---|---|
| Starting Dose | CJC-1295 100mcg + Ipamorelin 200-300mcg | Single nightly injection, 5-7 days/week |
| Titration | Increase by 100mcg increments every 4-8 weeks | Based on IGF-1 levels and symptom response |
| Timing | 30-60 minutes before bed | Aligns with natural nocturnal GH pulse |
| Baseline Labs | IGF-1, fasting glucose, lipids, PSA, CBC | Establishes safety profile before initiating |
| Follow-Up Monitoring | IGF-1 every 4-8 weeks initially, then q3-6 months | Target upper-normal range (age-adjusted) |
| Maximum Duration | Cycle 3-6 months, assess need for continuation | Long-term safety data beyond 6 months is limited |
Reconstitute the lyophilized powder with bacteriostatic water immediately before use. Store mixed vials refrigerated and use within 30 days. Rotate injection sites to minimize local reactions.
Side Effects & Safety Profile
Most side effects are mild and transient. The biggest concern with any GH-stimulating therapy is potential long-term cancer risk, though no definitive human data links peptide secretagogues to oncogenesis.
| Frequency | Side Effect | Management Strategy |
|---|---|---|
| Common (>10%) | Injection site reactions (redness, itching) | Rotate sites, apply ice, use proper technique |
| Common (>10%) | Transient water retention | Reduce sodium intake, lower dose if persistent |
| Occasional (1-10%) | Headache, mild nausea | Usually resolves within first 2 weeks |
| Occasional (1-10%) | Carpal tunnel symptoms (numbness, tingling) | Dose reduction typically resolves symptoms |
| Rare (<1%) | Hypersensitivity reactions | Discontinue immediately if allergic response |
| Rare (<1%) | Elevated fasting glucose | Monitor HbA1c, adjust if prediabetic patterns emerge |
Drug interactions are minimal since these peptides don't interact with cytochrome P450 enzymes. Insulin sensitivity may change — diabetics should monitor glucose closely.6
Pregnancy and breastfeeding safety is unknown — avoid use. No human reproduction studies exist for either peptide.
Cost & Where to Get It
Expect to pay $200-400 per month for a compounded Ipamorelin/CJC-1295 blend. Price varies by pharmacy, dose strength, and whether your clinic marks it up.
Insurance won't cover this. No FDA approval means it's classified as investigational, so you're paying cash.
Compounding pharmacies are your only source — brands like Empower, Hallandale, and Tailor Made ship directly to patients with a prescription. Some TRT telehealth clinics (Maximus, Marek Health) include peptides in their protocols and handle fulfillment.
You'll also need syringes, alcohol wipes, and bacteriostatic water for reconstitution if your pharmacy doesn't provide pre-mixed vials. Budget an extra $20-30/month for supplies.
Most clinics require baseline labs before prescribing, adding $150-300 upfront. Follow-up IGF-1 tests cost $50-80 each.
Beware of research chemical vendors and international peptide suppliers. Quality control is nonexistent, contamination is common, and you have no legal recourse if something goes wrong. Stick with U.S. compounding pharmacies operating under state pharmacy board oversight.
