Ipamorelin & CJC-1295
The most-asked-about growth hormone peptide pair, run together as a medically supervised stack. Two complementary mechanisms, naturalistic GH pulses, and an honest read on what the research supports. Serving Naperville, Oak Brook, Downers Grove, and Chicago’s western suburbs.
Book a ConsultationWhat are Ipamorelin and CJC-1295?
Two peptides that ask your body to release its own growth hormone, in tandem.
Ipamorelin and CJC-1295 are two peptides that work on different parts of the same axis. CJC-1295 mimics growth hormone-releasing hormone (GHRH), the upstream signal your hypothalamus sends to your pituitary gland. Ipamorelin is a growth hormone secretagogue (a GHRP) that acts on a separate ghrelin receptor at the pituitary to trigger a selective GH pulse.
Run together, they generate naturalistic GH pulses without supplying growth hormone directly. Both are delivered as small subcutaneous injections, typically nightly before bed, to align with the body’s overnight growth hormone cycle. This is one of the most-requested peptide pairs in our clinic, especially among patients focused on sleep, recovery, and lean body composition.
- + Two complementary mechanisms in one stack
- + Ipamorelin is more selective than older GHRPs in published reports
- + Pulses preserve the body’s own feedback loops
- + Research suggests support for deep sleep and recovery
- + Often the next step after a sermorelin cycle
What the GH peptide stack may support.
Sleep & Recovery
Most of the body’s growth hormone is released during deep, slow-wave sleep. Research suggests GHRH and GHRP peptides like ipamorelin and CJC-1295 may support that overnight pulse, which is why many clients notice sleep quality changes first. Recovery from training and physical stress often tracks with the same shift.
- May support slow-wave (deep) sleep
- Studied for post-training recovery
- Dosed at bedtime to match the natural cycle
Lean Body Composition
Over longer cycles, research suggests GH peptides may support a shift toward more lean mass and less fat mass in adults with age-related growth hormone decline. Changes tend to build slowly across months, alongside training and nutrition, not overnight. Outcomes vary; we don’t promise specific results.
- May support lean mass over a cycle
- Best paired with training and protein intake
- Evidence still building
Energy & Well-Being
Adults experiencing somatopause, the age-related decline in growth hormone, sometimes report flatter energy and lower well-being. Research suggests GHRH and GHRP peptides may support energy and overall sense of well-being in this group. Human evidence is still emerging, so we treat it as a supportive tool, not a cure.
- Active research area in age-related GH decline
- Often reported alongside sleep gains
- Outcomes vary client to client
A note on honesty: the ipamorelin / CJC-1295 stack is an active area of clinical practice, not a miracle. We’ll tell you what the evidence supports and what it doesn’t. Curious about other GH peptides? Compare with Sermorelin and Tesamorelin.
Two peptides, two pathways, one stronger signal.
CJC-1295
Mimics growth hormone-releasing hormone (GHRH), the upstream signal from the hypothalamus. Asks the pituitary to release GH in pulses. Longer-acting than sermorelin, which is why it’s often the GHRH chosen for stacking.
- · Acts on GHRH receptors at the pituitary
- · Extends the GHRH signal duration
- · DAC variant runs even longer half-life
- · Feedback loops remain intact
Ipamorelin
Triggers a selective GH pulse through the ghrelin receptor, a separate pathway from GHRH. More selective than older GHRPs in published reports, with minimal effect on cortisol or prolactin. Often the GHRP of choice in clinical protocols.
- · Acts on ghrelin receptor at the pituitary
- · Selective GH pulse without significant cortisol/prolactin shifts
- · Shorter half-life, dosed near bedtime
- · Complementary to a GHRH analog like CJC-1295
Why the pair is run together: CJC-1295 turns up the GHRH signal while ipamorelin opens a second GH-release pathway through the ghrelin receptor. Research and clinical practice suggest the combination produces a stronger, more naturalistic GH pulse than either peptide alone. Both peptides are compounded and not FDA approved as finished products. Curious about the broader peptide landscape? Read the peptide therapy overview or compare with sermorelin.
What the GH Peptide Stack Costs at Defiant
Pricing varies because the protocol is built around your goals, labs, and the length of cycle that fits your plan. We don’t sell ipamorelin or CJC-1295 off-the-shelf, and we don’t bundle you into a fixed package that may not match how your body responds.
What you can expect from a Defiant ipamorelin / CJC-1295 program:
- Compounded ipamorelin and CJC-1295 from a licensed compounding pharmacy, dosed for your protocol (often as a blended formulation for convenience)
- Provider consult and prescription, with a full review of medical history, medications, and goals
- Bloodwork-informed dosing (orders written by Defiant; draws done through your PCP or Rythm Health)
- Ongoing nurse and provider access through the program
- Optional cycle extension based on how you respond, not a fixed end-date
Most patients run a 3-to-6 month initial cycle, with monthly medication and follow-up. Stacking ipamorelin and CJC-1295 together is more cost-effective than running them as two separate programs. Exact pricing depends on dose, cycle length, and whether you bundle with other peptides or a membership tier.
The honest version: we quote pricing at the free consultation so you can see exactly what the cycle costs before you commit. We’d rather give you a real number against your protocol than a list price that doesn’t match your dose.
Membership savings: Elite-tier members receive 20% off compounded peptide protocols, which generally covers the difference in the first cycle.
