CJC-1295 No DAC (Mod GRF 1-29)
CJC-1295 No DAC (Mod GRF 1-29) scored 4.5 / 10 (⚖️ Neutral) on the BioHarmony scale as a Substance → Peptide → Growth / Repair Peptide.
CJC-1295 No DAC (Mod GRF 1-29) is a short-acting GHRH peptide, almost always stacked with ipamorelin, that prompts a pulse of your own growth hormone. Human data exists only for the long-acting DAC version, per Teichman 2006; the no-DAC form has no dedicated human trial, and neither form has a human outcome study.
What is CJC-1295 No DAC (Mod GRF 1-29)?
CJC-1295 No DAC, better known as Mod GRF 1-29, is a lab-made peptide that nudges your own pituitary to release a short pulse of growth hormone, and the "No DAC" part is the whole point. It activates the growth-hormone-releasing-hormone receptor, then clears in about 30 minutes, so it mimics the brief, natural rise and fall your body produces on its own. That is the version people stack with ipamorelin. Its long-acting sibling, CJC-1295 with DAC, binds to albumin and keeps growth hormone elevated for 6 to 8 days, a sustained "bleed" most experienced users avoid as non-physiological.
Here's the catch, and it's a big one. Almost all the human data belongs to the DAC form, which raised growth hormone and IGF-1 in healthy adults, per Teichman 2006 and Ionescu and Frohman 2006. The no-DAC form you inject has never been tested in a published human trial, and neither form has a study showing the fat loss, recovery, or sleep benefits people buy it for. So the score reflects an honest gap: a real growth-hormone mechanism, paired with ipamorelin by almost everyone, resting on borrowed and surrogate evidence.
Terminology
A few terms decide how you read this report, because the gap between "the hormone rises" and "the outcome is proven" is exactly where CJC-1295 lives, and because the two forms get confused constantly.
- GHRH: Growth-hormone-releasing hormone. The natural signal CJC-1295 imitates to trigger a growth-hormone pulse.
- No-DAC / Mod GRF 1-29: The short-acting form, cleared in about 30 minutes, that preserves a natural pulse. The subject of this report.
- DAC: Drug Affinity Complex. A modification that binds the peptide to albumin, stretching its life to 6 to 8 days for a sustained release. A different risk profile.
- IGF-1: Insulin-like growth factor 1. The downstream signal growth hormone produces, the marker users track, and the pathway behind the cancer concern.
- Pulsatile vs sustained: Your body releases growth hormone in bursts. No-DAC copies the burst; DAC floods the system continuously.
- Ipamorelin: The ghrelin-receptor peptide almost always stacked with CJC-1295 no-DAC, hitting a second pathway to growth hormone. It has its own BioHarmony scorecard.
- Tesamorelin: An FDA-approved GHRH analogue with the same short kinetics and real human trials, per Falutz 2007; the better-evidenced cousin.

What are the benefits of CJC-1295 No DAC (Mod GRF 1-29)?
Upside contribution: 1.38
| Dimension | Weight | Score | Visual | Weighted |
|---|---|---|---|---|
| Efficacy | 25% | 2.4 | 0.600 | |
| Breadth | 15% | 3.0 | 0.450 | |

| Bioindividuality | 15% | 3.0 | 0.450 | |
| Total | 2.375 |
Upside Rationale
The upside is concentrated in mechanism, not in proven results, and even the mechanism evidence belongs to a different form. CJC-1295's genuine asset is a clean, physiological growth-hormone pulse that pairs well with ipamorelin; its weakness is that no human trial shows this produces the body-composition, recovery, or sleep outcomes people want, and the no-DAC version has never been tested in people at all. Breadth and bioindividuality score moderately because the growth-hormone axis plausibly touches many systems and response clearly varies by age. Evidence is the dimension that drags the total down hardest.
Efficacy (2.4/5.0): Efficacy is low because the growth-hormone rise is real but its payoff is undemonstrated in humans, and the human rise was measured on the DAC form, not this one. CJC-1295 DAC reliably raised growth hormone and IGF-1 in healthy adults, per Teichman 2006, confirmed by Ionescu and Frohman 2006. What is missing is any human trial showing fat loss, muscle gain, or faster recovery for either form, and the no-DAC version has no dedicated human pharmacology study. A confirmed hormone rise without a confirmed human outcome cannot score as effective for the uses people care about.
Breadth of Benefits (3.0/5.0): Breadth is moderate because growth hormone plausibly influences many systems even though few are proven for CJC-1295. The growth-hormone axis touches body composition, sleep, recovery, skin, and bone in theory, and the small human work confirms the upstream hormone signal moves, per Sackmann-Sala 2009. The boundary is that breadth of mechanism is not breadth of proof: in humans, none of these systems has a controlled CJC-1295 endpoint, and the strongest body-composition data belongs to a different analogue, tesamorelin, per Falutz 2007.
Evidence Quality (1.5/5.0): Evidence quality is the weakest dimension and the reason the score sits in caution. There are no human outcome trials for either form, and the form people run, no-DAC, has no dedicated human study at all. The real human pharmacology, a sustained growth-hormone and IGF-1 rise, was measured on the DAC version, per Teichman 2006, and cannot be transferred to the pulsatile no-DAC form. This lands below ipamorelin, where at least one human trial was run, because a single tested compound is more informative than an untested one. Everything else is class-level data and anecdote.
Speed of Onset (3.0/5.0): Speed is a relative bright spot. The growth-hormone pulse peaks within about 30 minutes of a subcutaneous dose, so the acute pharmacology is fast. Subjectively, the most consistent community report is deeper sleep within the first 1 to 2 weeks, consistent with growth-hormone-releasing-hormone effects on non-REM sleep seen at the class level, per Schussler 2006. The fast hormonal action is well-supported; the fast subjective effect is anecdotal, comes from the ipamorelin stack rather than CJC-1295 alone, and appears to vary by sex and age.
Durability (2.0/5.0): Durability is low because benefits depend on continued dosing. The no-DAC pulse is transient by design, and the axis returns to baseline between doses, so any effect fades when you stop. There is no published evidence of lasting change after a cycle ends, and the community cycles 8 to 12 weeks specifically out of concern that continuous stimulation blunts response over time. This is a maintain-to-keep-it tool, not a reset.
Bioindividuality Upside (3.0/5.0): Response varies enough that some users notice clearly more than others. Older adults and those with lower baseline growth-hormone output tend to show larger relative responses, while younger users with a healthy axis often report little. The class-level sleep effect appears sex-dependent, per Kluge 2008, which adds another axis of variation. Predictable modifiers exist, which lifts this above average, but they also mean a meaningful share of users will feel nothing.

Downside Rationale
The downside is dominated by uncertainty and a bothersome side-effect profile rather than acute danger, at least for the no-DAC form. At standard pulsatile doses CJC-1295 has no documented intrinsic catastrophic effect, and it clears in half an hour, so side effects are correctable fast. The heavier weights come from the flushing-and-fluid side-effect cluster, the daily-injection burden, and a real opportunity cost: tesamorelin does the same job with actual human trials behind it. Dependency is low and reversibility is excellent. The DAC form carries materially more risk and is scored separately in spirit.
Safety Risk (2.6/5.0): Safety risk is moderate, driven by unknowns rather than a confirmed catastrophic signal for the no-DAC form. At standard pulsatile doses there is no established intrinsic life-threatening effect, and the short half-life means anything that goes wrong clears quickly. The theoretical concerns are growth-hormone biology: raised IGF-1, the same marker the DAC form elevated per Ionescu and Frohman 2006, feeds proliferation pathways, so active cancer is an absolute contraindication, and reduced insulin sensitivity is possible. The long-acting DAC version is a different story, carrying an unresolved trial death in a patient with pre-existing heart disease and a sustained-release profile that cannot be reversed for days. That history loads onto the DAC form, not this one.
Side Effect Profile (2.8/5.0): Side effects are the heaviest practical downside for no-DAC. The signature complaint is a flushing reaction, warmth and facial redness within 30 minutes of injection, reported by roughly 30 to 40 percent of users and prominent enough that some experts switched away from CJC-1295. Water retention, headache, and tingling or numbness from fluid shifts are common and dose-dependent. Most fade with continued use or a dose reduction, and the short half-life means they pass within hours rather than lingering.
Financial Cost (2.6/5.0): Cost is moderate and ongoing. Research-grade no-DAC commonly runs 30 to 60 dollars per vial, but daily dosing plus the near-mandatory ipamorelin, plus IGF-1 testing, pushes a real cycle toward a few hundred dollars a month. It is not expensive per dose; the recurring spend on an unproven stack is the relevant framing.
Time/Effort Burden (3.2/5.0): Effort is meaningful. CJC-1295 no-DAC requires reconstitution with bacteriostatic water, subcutaneous injection one to three times daily in a fasted state, careful timing around food and sleep, cold-chain storage, and site rotation. That is a real daily logistics load compared with an oral supplement, and the fasted-timing rules add friction most people underestimate.
Opportunity Cost (3.0/5.0): Opportunity cost is genuine and higher than for most peptides in this class, because a better-evidenced option exists. Tesamorelin shares the same pulsatile kinetics, is FDA-approved, and has human visceral-fat-loss data, per Falutz 2007. An oral secretagogue like MK-677 removes the injections entirely. Money and effort spent on the unproven CJC-1295 stack could go to those, or to the training, protein, and sleep basics that move the same goals with far more certainty.
Dependency/Withdrawal (2.5/5.0): Dependency risk is low. CJC-1295 is non-suppressive: it does not shut down a hormonal axis the way exogenous growth hormone can, so benefits simply fade when dosing stops, which is functional reliance rather than withdrawal. The open question is receptor desensitization with long continuous use, which is why the community cycles, but there is no documented addiction or withdrawal syndrome.
Reversibility (1.8/5.0): Reversibility is excellent for the no-DAC form, one of its genuine strengths. The roughly 30-minute half-life means a bad reaction or unwanted side effect clears within hours, and stopping returns the growth-hormone axis to baseline without a taper or lasting change. This is a sharp contrast with the DAC form, where a side effect triggered on Monday persists until the following week.
Is CJC-1295 No DAC (Mod GRF 1-29) worth it?
CJC-1295 No DAC sits in caution because it pairs a clean, physiological mechanism with an almost empty human outcomes file and a form that has never been tested in people. If you want a short-acting growth-hormone pulse to stack with ipamorelin, accept that the benefits are unproven, can source verified no-DAC material, and will monitor IGF-1 and glucose, it is a reasonable low-drama experiment. If you expect evidence-backed fat loss or recovery, the data is not there, and the better-supported path is tesamorelin plus ipamorelin, per Falutz 2007. The two biggest real-world frictions are the flushing reaction and unregulated sourcing.
✅ Best for: Experienced users who value a physiological, pulsatile growth-hormone pattern and will run it with ipamorelin. Older adults with lower baseline growth-hormone output, who tend to respond more. People chasing the most consistently reported effect, deeper sleep, who will judge it on their own response over a few weeks. Anyone who can verify they have the no-DAC form by certificate-of-analysis molecular weight and obtain pharmaceutical-grade material. Users who already have training, protein, and sleep dialed in and want a low-suppression add-on.
❌ Avoid if: You have active or hormone-sensitive cancer, since growth-hormone and IGF-1 signaling can promote proliferation. You are pregnant or breastfeeding, with no safety data. You have uncontrolled diabetes or insulin resistance, because growth hormone opposes insulin. You have significant cardiovascular disease, especially if considering the DAC form given its unresolved trial-death history. You compete in tested sport, since growth-hormone-releasing factors are banned at all times under WADA S2. You cannot verify source quality or form, because no-DAC is frequently mislabeled and research-chemical contamination may exceed the intrinsic pharmacological risk.
What is CJC-1295 No DAC (Mod GRF 1-29) best for?
The overall BioHarmony score reflects the intervention's primary evidence profile. These subratings are independent assessments per use case.
| Use Case | Score | Summary |
|---|---|---|
| ○ Sleep Quality Primary | 3.0 | Sleep is the most consistently reported benefit and the main reason people stay on the stack, but it is not proven for CJC-1295 alone. The signal comes from the CJC plus ipamorelin combination, and the growth-hormone-releasing-hormone class can promote non-REM sleep in some human paradigms, per Schussler 2006 and Kluge 2008. The effect appears sex- and age-dependent, and no no-DAC sleep trial exists. |
Frequently Asked Questions
What does CJC-1295 no-DAC do, and how is it different from the DAC version?
CJC-1295 no-DAC, also called Mod GRF 1-29, tells your pituitary to release a short pulse of growth hormone by activating the growth-hormone-releasing-hormone receptor. It clears in about 30 minutes, so it mimics the body's natural pulse. The DAC version binds to albumin and keeps growth hormone elevated for 6 to 8 days, a sustained bleed most users avoid as non-physiological. The no-DAC form is the one stacked with ipamorelin.
How much CJC-1295 no-DAC do people take, and when?
Community protocols run 100 to 200 mcg subcutaneously, 1 to 3 times daily, fasted, with a pre-sleep dose the most common. These are not approved doses. The growth-hormone receptor saturates near 100 to 200 mcg per pulse, so larger single doses are wasted. The dominant pairing adds ipamorelin at roughly 1:1, often in one syringe. Avoid food for 2 to 3 hours before and 20 to 30 minutes after, since insulin blunts the pulse.
What does the human evidence on CJC-1295 show?
Human evidence exists only for the long-acting DAC form, which raised growth hormone 2 to 10 times and IGF-1 1.5 to 3 times, per Teichman 2006 and Ionescu 2006. Those are surrogate hormone markers, not outcomes. No human trial shows fat loss, muscle gain, recovery, or sleep benefit for either form, and the no-DAC version has no dedicated human study at all.
Is CJC-1295 safe?
The short-acting no-DAC form has no documented catastrophic signal at standard doses, and effects clear within hours. Common side effects are a flushing reaction, water retention, headache, and tingling. The long-acting DAC form is riskier: its development was halted after a trial death in an HIV patient with pre-existing heart disease, a cause never independently confirmed. Theoretical long-term concerns, raised IGF-1 and reduced insulin sensitivity, apply to both forms and lack long-term human data.
Who should avoid CJC-1295?
Anyone with active or hormone-sensitive cancer, pregnancy, uncontrolled diabetes, or significant cardiovascular disease should avoid CJC-1295, because growth-hormone-axis stimulation can worsen those conditions. Competitive athletes must avoid it too: the World Anti-Doping Agency prohibits growth-hormone-releasing factors at all times under category S2, naming CJC-1295 specifically.
How fast does CJC-1295 work?
The growth-hormone pulse itself is fast, peaking within about 30 minutes. The most consistent subjective signal, deeper sleep, is reported within 1 to 2 weeks on the ipamorelin stack. Recovery and skin changes are described over 4 to 12 weeks, and body-composition changes, if any, over 3 to 6 months. None of these timelines come from controlled trials, so treat them as community expectations.
CJC-1295 plus ipamorelin vs tesamorelin: which is better?
Tesamorelin has the stronger evidence. It is an FDA-approved growth-hormone-releasing-hormone analogue with human trials showing about a 15 percent reduction in visceral fat, per Falutz 2007, and it shares the same short, pulsatile kinetics as CJC-1295 no-DAC. CJC-1295 plus ipamorelin is cheaper and widely used, but the stack has never been tested in a human outcome trial. If access and budget allow, tesamorelin plus ipamorelin is the better-supported choice.
Is CJC-1295 legal, and how do you get quality material?
CJC-1295 is not FDA-approved and sits in a regulatory grey area: an FDA advisory committee reviewed it for compounding and it remains outside approved use. In practice it comes from research-chemical vendors, where mislabeling no-DAC as DAC is common. Verify the form by the certificate-of-analysis molecular weight, about 3,368 for no-DAC versus about 3,649 for DAC, and require third-party HPLC purity with mass-spec identity.
What could change CJC-1295 No DAC (Mod GRF 1-29)'s score?
BioHarmony scores are living assessments. New research, regulatory changes, or personal context can shift the score up or down. These are the most likely scenarios that would change this intervention's rating.
The fastest path up is human outcome data for the no-DAC form, and the fastest path down is a documented safety signal or confirmation that the stack adds nothing. A single positive human trial in body composition or sleep would lift Efficacy and Evidence together and move CJC-1295 toward worth-trying. A head-to-head showing the ipamorelin stack beats either peptide alone would do the same. Because the current score rests on an empty human file for this form, even modest real evidence in either direction would move it more than usual.

BioHarmony translates a weighted expected-value calculation into a reader-facing 0–10 score. Tier bands: Skip 0–3.6, Caution 3.7–4.7, Neutral 4.8–5.7, Worth Trying 5.8–6.9, Strong Recommend 7.0–7.9, Top-tier 8.0+.
Harm-type downsides (safety risk, side effects, reversibility, dependency) carry a 1.4× precautionary multiplier. Harm weighs more than benefit. Opportunity-type downsides (financial cost, time/effort, opportunity cost) are subtracted at face value.
Use case subratings are independent assessments of how well the intervention addresses specific health goals. They are not components of the overall score. Each subrating reflects the scorer's judgment based on use-case-specific evidence, safety, and effect sizes.
Every dimension is evaluated on a 1–5 scale, and the baseline (1) is subtracted before weighting. A perfect intervention with zero downsides contributes zero penalty rather than a residual floor, so top-tier scores are actually reachable.
EV = Upside − Downside
EV = 1.375 − 1.935 = -0.560
Formula v0.5 maps EV = 0 to score 5.0. Above neutral, 1 EV point equals 1 score point. Below neutral, 1 EV point equals about 0.71 score points, so EV = −7 reaches 0.0 while EV = +5 reaches 10.0. Both sides use the full 5-point half-scale.
Score = 5 + (-0.560 / 7) × 5 = 4.6 / 10
