CJC-1295 is the most searched growth hormone peptide on the internet — over 33,000 people look it up every month. That volume reflects both genuine clinical interest and a market flooded with misinformation. Here is what the data actually supports.
CJC-1295 is a synthetic analog of growth hormone releasing hormone (GHRH). It stimulates the pituitary gland to produce and release growth hormone (GH) in a pulsatile pattern that mimics natural physiology. Unlike direct GH injection, CJC-1295 works through the body's own feedback mechanisms, which means fewer side effects and a more physiological GH profile.
As of early 2026, CJC-1295 is Category 1 — meaning it can be legally compounded and prescribed by licensed physicians through telehealth clinics. This is a significant shift from the grey-market-only era.
CJC-1295 With DAC vs Without DAC (Mod GRF 1-29)
This is the single most important distinction that most guides gloss over. There are two forms of CJC-1295, and they behave very differently.
CJC-1295 with DAC (Drug Affinity Complex)
The DAC modification binds CJC-1295 to albumin in the bloodstream, extending its half-life to 6-8 days. This means sustained, elevated GH levels rather than sharp pulses.
- •Half-life: 6-8 days
- •Dosing frequency: Typically 1-2x per week
- •GH pattern: Sustained elevation (less pulsatile)
- •Convenience: Fewer injections
- •Tradeoff: The sustained GH elevation does not perfectly mimic natural GH secretion, which occurs in pulses
CJC-1295 without DAC (Mod GRF 1-29)
Without the DAC modification, the peptide has a much shorter half-life of approximately 30 minutes. This produces sharp GH pulses that more closely resemble the body's natural secretion pattern.
- •Half-life: ~30 minutes
- •Dosing frequency: 1-3x daily (often before bed)
- •GH pattern: Sharp pulses (more physiological)
- •Tradeoff: Requires more frequent administration
- •Preferred by: Most clinics and researchers who want to preserve natural GH pulsatility
| Feature | CJC-1295 with DAC | CJC-1295 without DAC (Mod GRF 1-29) |
|---|---|---|
| Half-life | 6-8 days | ~30 minutes |
| Injection frequency | 1-2x/week | 1-3x/day |
| GH pattern | Sustained elevation | Sharp pulses |
| Mimics natural GH? | Less closely | More closely |
| Most common use | Convenience-focused protocols | Clinical and research protocols |
Clinic preference: Most prescribing clinics use the no-DAC version (Mod GRF 1-29), almost always paired with Ipamorelin.
The CJC-1295 + Ipamorelin Combo — Why Clinics Pair Them
If you have looked into CJC-1295 at all, you have probably seen it mentioned alongside [Ipamorelin](/compounds/ipamorelin). There is a reason this combination is the most widely prescribed GH peptide protocol in clinical practice.
The mechanism is synergistic. CJC-1295 is a GHRH analog — it tells the pituitary *how much* GH to release. [Ipamorelin](/compounds/ipamorelin) is a ghrelin mimetic (GHSR agonist) — it tells the pituitary *when* to release it. When combined, they amplify each other's signal without increasing side effects proportionally.
Key advantages of the combo:
- •Greater GH output than either peptide alone at the same dose
- •Selective GH release — Ipamorelin does not significantly raise cortisol or prolactin (unlike older secretagogues like <a href="/compounds/ghrp-6">GHRP-6</a>)
- •Preserved pulsatility — the combination still triggers discrete GH pulses rather than a constant drip
- •Well-studied safety profile — this is the most prescribed GH peptide stack in the US clinic space
Reported benefits in clinical contexts include improved sleep quality, enhanced recovery from exercise, improved body composition (reduced fat, preserved lean mass), and improved skin quality. Individual results vary, and these outcomes depend on dose, protocol duration, and baseline health.
Legal Status: Category 1, Prescription Available
CJC-1295 is classified as Category 1 under the current FDA compounding framework. This means:
- •Licensed physicians can prescribe it
- •FDA-registered compounding pharmacies can produce it
- •Telehealth clinics can legally offer it nationwide
- •No customs risk, no grey market ambiguity

Clinics Offering CJC-1295/Ipamorelin
We have evaluated six clinics that currently prescribe the CJC-1295/Ipamorelin combination. Scores are based on our four-category rubric covering transparency, physician quality, pricing, and patient reviews.
| Clinic | Score | Monthly Cost | Reviews | Notes |
|---|---|---|---|---|
| [Defy Medical](/clinics/defy-medical) | 8.8/10 | $200-500 | 4.9★ (3,779) | Most experienced clinic, extensive lab work included |
| [Peter MD](/clinics/peter-md) | 8.2/10 | $150-400 | 4.8★ (13,947) | Largest review volume, competitive pricing |
| [Relive Health](/clinics/relive-health) | 7.2/10 | $200-500 | — | In-person + telehealth hybrid model |
| [Maximus](/clinics/maximus) | 7.0/10 | $100-300 | — | Budget-friendly entry point |
| Viking Alternative | 6.8/10 | $100-350 | — | Lower cost, less established |
| The Protocole | 6.5/10 | $150-400 | — | Newer entrant, limited track record |
Our take: [Defy Medical](/clinics/defy-medical) is the strongest option if you want thorough physician oversight and comprehensive bloodwork. [Peter MD](/clinics/peter-md) offers the best combination of price and patient satisfaction at scale. For budget-conscious patients, Maximus provides a lower entry point.

CJC-1295 vs Sermorelin vs MK-677
CJC-1295 is not the only option for boosting growth hormone. Here is how it compares to two common alternatives.
| Compound | Mechanism | Half-life | Route | Prescription? | Key Tradeoff |
|---|---|---|---|---|---|
| [CJC-1295](/compounds/cjc-1295) (no DAC) | GHRH analog | ~30 min | Injection | Yes (Category 1) | Gold standard combo with Ipamorelin |
| [Sermorelin](/compounds/sermorelin) | GHRH analog | ~10 min | Injection | Yes (Category 1) | Older compound, shorter duration, well-studied |
| [MK-677](/compounds/mk-677) (Ibutamoren) | Ghrelin mimetic | ~24 hrs | Oral | No (Category 2) | Oral convenience, but raises appetite and blood sugar |
- •[Sermorelin](/compounds/sermorelin) was the first-generation GHRH analog. It works similarly to CJC-1295 but has a much shorter half-life (~10 minutes vs ~30 minutes). CJC-1295 largely replaced it in clinical protocols due to better pharmacokinetics. Sermorelin is still prescribed and remains a solid option, especially for patients who prefer a well-established compound.
- •[MK-677](/compounds/mk-677) is appealing because it is oral — no injections required. However, it is a ghrelin mimetic that raises appetite significantly and can increase blood glucose and insulin levels. It is also still Category 2, meaning it is not available through legal clinic channels. For researchers only.

The Bottom Line
CJC-1295 is the backbone of modern growth hormone peptide therapy. The combination with [Ipamorelin](/compounds/ipamorelin) is the most widely prescribed GH peptide protocol for good reason — the synergistic mechanism produces meaningful GH elevation with a favorable side effect profile.
If you want legal, medically supervised access: Go through a [clinic](/clinics). CJC-1295 is Category 1 and available by prescription. [Defy Medical](/clinics/defy-medical) and [Peter MD](/clinics/peter-md) are the strongest options based on our scoring.
If you are a researcher: The [vendor market](/vendors) offers CJC-1295 at $3.75-10.00/mg. Prioritize Finnrick-verified vendors for purity assurance.
If you are choosing between CJC-1295, Sermorelin, and MK-677: CJC-1295 + Ipamorelin is the current clinical standard. Sermorelin is a reasonable alternative with a longer track record. MK-677 offers oral convenience but comes with metabolic tradeoffs and remains in a legal grey area.
