CJC-1295 with DAC 2026: Cost, Samples & Access for the Long-Acting GHRH Peptide
CJC-1295 with DAC (Drug Affinity Complex) is a modified GHRH analog with a half-life extended to roughly 7-10 days via covalent binding to plasma albumin. The 'DAC' modification is what differentiates this variant from CJC-1295 no-DAC (Modified GRF 1-29), which has a much shorter half-life and requires multiple weekly injections.
The clinical appeal of CJC-1295 with DAC is convenience: once-weekly dosing produces a sustained background elevation in GH and IGF-1 rather than the pulse-pattern produced by sermorelin or short-acting GHRH analogs. Whether sustained elevation or pulse-pattern dosing is preferable is an active clinical debate; the answer is patient- and protocol-specific.
CJC-1295 was removed from the FDA Cat-2 list in September 2024 along with several other peptides and remains in regulatory limbo pending PCAC review. 503A compounding continues; clinical prescription remains routine.

What's actually available: CJC-1295 with DAC samples in 2026
Three paths for people typing “cjc-1295 with dacsamples” — what they actually mean, typical cost, and who each path fits.
| Path | What it actually is | Typical cost | Best for |
|---|---|---|---|
| Telehealth peptide subscription | Specialty telehealth (Marek, Defy, some Hone protocols) — bundle of consult + CJC-1295 with DAC + ipamorelin. | $129-279 / month all-in | Patients prioritizing once-weekly GHRH dosing for adherence |
| Peptide clinic (Marek / Defy / LIVV) | Specialty clinic with full lab panels and protocol customization including CJC-1295 vs sermorelin tradeoff. | $250-500 / month | Patients integrating CJC-1295 into broader optimization protocols |
| 503A pharmacy via clinician | Direct 503A fill via established clinician relationship. | $70-200 / vial (multi-week supply) | Patients with established prescription managing ongoing cost |
How CJC-1295 with DAC samples actually work
What 'with DAC' actually means
CJC-1295 was developed in two variants. The 'no DAC' version (also called Modified GRF 1-29) has the four-amino-acid modifications that resist enzymatic degradation but no albumin-binding tail — half-life is ~30 minutes. The 'with DAC' version adds a Drug Affinity Complex (a maleimidopropionic acid linker) that covalently binds to plasma albumin, extending half-life to 7-10 days. That's the structural difference; everything else flows from it.
Sustained elevation vs pulse-pattern
Sermorelin and CJC-1295 no-DAC produce discrete GH pulses that mimic natural physiology. CJC-1295 with DAC produces a sustained background elevation in GH and IGF-1. Proponents of pulse-pattern argue it respects natural feedback loops; proponents of sustained elevation argue clinical convenience and stable IGF-1 are worth the trade. Both views have clinical advocates; the choice is patient- and protocol-specific.
Why the GHRP pairing still matters
Even with CJC-1295's sustained elevation, pairing with ipamorelin (a GHRP) amplifies the pituitary response. Most CJC-1295 with DAC protocols pair the weekly CJC injection with daily evening ipamorelin. The CJC sets the baseline; the daily ipamorelin pulses on top of it.
The DAC modification trades pulse fidelity for dosing convenience. Whether sustained GH elevation or natural pulse-pattern is preferable depends on the protocol, the patient, and the goal — not on which molecule is 'better'.
CJC-1295 with DAC cost in 2026: every legitimate price path
What you'll actually pay depends on insurance, the path you take, and whether you stay on the brand-name drug. Here's the real money:
| Path | First month | Ongoing | Notes |
|---|---|---|---|
| Telehealth combo bundle | $149-199 | $129-279 / mo | CJC-1295 with DAC + ipamorelin combo pricing. |
| Specialty peptide clinic | $350-700 | $250-500 / mo | Full labs + protocol customization. |
| 503A pharmacy via clinician | $200-450 | $70-200 / vial | Multi-week supply per vial; lowest ongoing cost. |
What to expect on CJC-1295 with DAC: your first weeks
Baseline labs (IGF-1, fasting metabolic, prolactin) before initiating.
IGF-1 typically rises measurably in the first 2-4 weeks with weekly dosing.
Sustained elevation pattern (rather than pulse pattern) shows up clearly in 8-12 week labs.
Clinical evidence behind CJC-1295 with DAC
CJC-1295's pharmacokinetics — extended half-life via DAC, sustained IGF-1 elevation — are well-characterized in published literature. Long-term outcome data on body-composition and longevity endpoints is more limited; clinical use proceeds based on near-term lab response and patient feedback. Regulatory status pending PCAC review.
CJC-1295 with DACside effects & who shouldn't take it
This is not medical advice. Discuss every medication decision with a licensed clinician who knows your full medical history.
Common side effects
- •Injection-site soreness, redness
- •Headache during first 1-2 weeks

Who shouldn't take CJC-1295 with DAC
- •Patients with active malignancy
- •Pregnancy or breastfeeding
- •Untreated diabetic retinopathy
- •Patients with significant insulin resistance
- •Patients who specifically prefer pulse-pattern physiology (sermorelin or CJC-1295 no-DAC may be a better fit)
Eligibility for CJC-1295 with DAC
- •Adult age 21+
- •Baseline IGF-1 and fasting metabolic panel in hand

CJC-1295 with DAC samples: frequently asked
Why would I choose CJC-1295 with DAC over sermorelin?
Two reasons: (1) once-weekly dosing convenience vs. daily sermorelin, (2) sustained IGF-1 elevation if your clinical goal favors that pattern. Sermorelin's daily pulse-pattern is closer to natural physiology; CJC-1295 with DAC's sustained elevation is more convenient and produces a flatter IGF-1 curve. Both are valid; the choice is protocol-specific.
Can I use CJC-1295 with DAC without ipamorelin?
You can, but most clinical protocols pair them because the GHRH + GHRP synergy applies regardless of which GHRH variant is used. Solo CJC-1295 with DAC produces a smaller GH response than the combo.
Is CJC-1295 with DAC the same as 'CJC-1295' without specification?
Not necessarily. Without specification, 'CJC-1295' often defaults to the no-DAC version (Modified GRF 1-29). The 'with DAC' designation is meaningful — it changes half-life from ~30 minutes to 7-10 days. Always confirm which version your prescription specifies.
Does CJC-1295 with DAC suppress endogenous GH production?
There is theoretical concern that sustained background elevation could blunt natural pulsatile GH release over time. The clinical literature is mixed; protocols frequently include cycling (5 days on, 2 days off; or quarterly breaks) to mitigate. Discuss cycling protocol with your prescribing clinician.
What's the difference between DAC and no-DAC pricing?
DAC variants are typically priced 30-60% higher per dose than no-DAC, but the weekly dosing convention means fewer doses per month. Per-month cost works out roughly comparable; the choice is convenience and pharmacokinetic preference.
