- Ipamorelin is a selective growth hormone releasing peptide (GHRP) that stimulates GH release without affecting cortisol or prolactin.
- CJC-1295 is a long-acting growth hormone releasing hormone analogue that prolongs the GH surge induced by GHRPs.
- Together they produce a synergistic, sustained increase in circulating growth hormone and IGF-1, enhancing muscle anabolism, fat loss, recovery, and overall tissue repair.
What is Ipamorelin?
Ipamorelin (Phe–Trp–Leu–Gly–Ala–Gln–Pro–Glu–Nle) is a pentapeptide that mimics ghrelin’s action on the growth hormone secretagogue receptor (GHS-R1a). It triggers GH release in a pulsatile fashion, preserving the natural circadian rhythm of hormone secretion.
Ipamorelin
Its primary advantage lies in its selectivity: unlike older GHRPs such as GHRP-2 or GHRP-6, ipamorelin does not elevate prolactin or cortisol levels, reducing unwanted side effects while maintaining robust GH stimulation.
Ipamorelin Overview
- Duration of action: 1–2 hours per injection.
- Typical dosage: 200–400 µg subcutaneously, 3–4 times daily.
- Onset: 30–45 minutes after injection.
What is CJC 1295?
CJC-1295 (also known as REMINYL) is a synthetic peptide that acts as a growth hormone releasing hormone analogue. It binds to the GHRH receptor, initiating GH secretion and simultaneously inhibiting somatostatin’s negative feedback.
CJC-1295 For Sale
While commercial availability varies by region, CJC-1295 can be sourced from licensed compounding pharmacies or specialized peptide distributors that comply with regulatory standards.
CJC-1295 Overview
- Half-life: 8–10 hours (due to a carboxyl-terminal fatty acid chain).
- Typical dosage: 100–300 µg once daily, usually at bedtime to align with natural GH peaks.
- Onset: 30–60 minutes post-injection.
How Does Ipamorelin + CJC 1295 Stack work together?
Ipamorelin primes the pituitary by activating GHS-R1a receptors, creating a surge of GH. CJC-1295 sustains this surge by prolonging receptor stimulation and blocking somatostatin inhibition. The result is a higher peak and extended duration of GH release compared to either peptide alone, leading to greater IGF-1 production in the liver and peripheral tissues.
Ipamorelin and CJC 1295 Stack for Fat Loss
Elevated GH levels promote lipolysis, increase fatty acid oxidation, and inhibit adipogenesis. The combined stack accelerates fat mobilization from visceral and subcutaneous depots while preserving lean mass during caloric restriction or intense training regimens.
Ipamorelin and CJC 1295 Stack for Muscle Mass
GH stimulates protein synthesis, satellite cell activation, and myofibrillar hypertrophy. IGF-1 enhances anabolic signaling pathways (e.g., PI3K/Akt/mTOR). Users often report improved muscle density, faster recovery, and greater endurance when the stack is paired with a structured resistance program.
Ipamorelin and CJC 1295 Dosage
A common protocol:
- Ipamorelin 200 µg SC pre-workout (30 min before training).
Adjustments may be made based on individual response, tolerance, and therapeutic goals.
Ipamorelin and CJC 1295 Benefits
- Enhanced muscle anabolism and lean tissue accrual.
- Accelerated fat loss with preservation of muscle mass.
- Improved sleep quality and recovery due to GH’s restorative effects.
- Reduced inflammation and joint pain through increased cartilage turnover.
- Potential neuroprotective benefits from elevated IGF-1 levels.
Ipamorelin and CJC 1295 Side Effects
- Mild injection site reactions (redness, swelling).
- Transient water retention or edema in some users.
- Rare headaches or dizziness when doses are high.
- Long-term safety data are limited; monitoring of IGF-1 levels is recommended to avoid excessive stimulation.
Is Ipamorelin and CJC 1295 Legal?
In many jurisdictions, these peptides are classified as research chemicals and not approved for human consumption. They may be legal for research purposes but using them for bodybuilding or therapeutic enhancement can violate local regulations. Users should verify the status in their country before procurement.
Who Should Use Ipamorelin and CJC 1295?
Ideal candidates include:
- Advanced athletes seeking incremental gains in muscle mass and recovery.
- Older adults experiencing age-related GH decline who require a safe anabolic stimulus.
- Individuals with clinical conditions such as growth hormone deficiency (under medical supervision).
Ipamorelin/CJC 1295 vs Other Compounds
Compared to older GHRPs, the stack offers reduced cortisol/prolactin spikes and a longer duration of action. When contrasted with HGH injections, it provides a more physiological GH release pattern and potentially lower risk of insulin resistance or edema.
Ipamorelin/CJC 1295 vs Sermorelin
Sermorelin is an endogenous GHRH analogue that stimulates GH but has a shorter half-life (~1 hour). The CJC-1295 component extends the effect, giving the ipamorelin stack superior duration and potency.
Ipamorelin/CJC 1295 vs Tesamorelin
Tesamorelin is approved for reducing abdominal fat in HIV patients; it has a fixed dosing schedule and stronger regulatory oversight. Ipamorelin + CJC-1295 offers broader anabolic benefits but lacks formal approval and clinical guidelines outside research settings.
Ipamorelin/CJC 1295 vs HGH
Direct HGH injections bypass the pituitary, leading to constant hormone levels that can disrupt circadian rhythms. The peptide stack mimics natural GH secretion cycles, potentially reducing adverse metabolic effects while delivering comparable anabolic outcomes.
Conclusion: Are Ipamorelin and CJC-1295 Worth It?
For those who prioritize a physiological approach to growth hormone stimulation—maximizing muscle gains, fat loss, and recovery with minimal hormonal disruption—the ipamorelin + CJC-1295 stack presents a compelling option. However, legal status, lack of long-term safety data, and the need for precise dosing underscore that this combination should be approached cautiously and ideally under professional guidance.
