Authoritative source:PubChem
What is CJC–1295, DAC or no DAC?
CJC-1295, also known as DAC:GRF(DAC stands for drug affinity complex), which was originally developed by ConjuChem Biotechnologies, as a treatment for growth hormone deficiency. It’s a synthetic peptide that can stimulate growth hormone secretion (GH). Generally, peptides degrade over time whatever it as a natural peptide created in your body or a synthetic variation. However, DAC can prevent this to happen and keep same biological activity in the peptides. Nowadays, the market appear 2 form of CJC-1295 peptide sale online, CJC-1295 with DAC, CJC-1295 without DAC(also known as Modified GRF 1-29), they’re both synthetic peptides that are a modified version of endogenous GHRG (1-29). However, since its inception, fitness enthusiasts and bodybuilders alike have found CJC-1295 particularly useful in gaining muscle, it works by increasing protein synthesis and insulin-like growth factor levels, can promote muscle tissue to grow, increase muscle mass and function.[1][2]
CJC 1295 with DAC is a growth hormone peptide, also it’s called CJC 1295 + DAC, which is synthetic GHRH (growth hormone releasing hormone) analogue made up of 30 amino acids, ussually it’s a white crystalline powder and needs to be reconstituted. With similar function to growth hormone releasing hormone.This means that your body can increase lean muscle, improve bone density and higher IGF-1 levels, when taking CJC-1295 with DAC. Recent research studies have shown that CJC – 1295 + DAC stimulates GH and IGF-1 Secretion, and will keep a steady increase of HGH and IGF-1 with no increase in prolactin, leading to fat loss and increases protein synthesis. So, CJC 1295 with DAC is known for being the finest of the hGH secretogues.
CJC 1295 without DAC(also called Modified GRF 1-29, CJC 1295 no DAC), is a synthetic peptide that stimulates growth hormone production, which be further modified from its GRF 1-29 variation, can stimulates growth hormone production. It is able to assist with rapid body fat reduction and faster recovery from strenuous activity, to promote substantial muscle gain and lean body composition, then help you improve your gains as well as overall health.
When you plan to buy finished peptide of CJC 1295 with/no DAC online, usually it comes as a 2mg/vial, 5mg/vial, 10vial/vial in lyophilized form appeared, better to choose top quality peptide manufacturer or seller with trusted comments, can ensure quality issue, help you to get an amazing effect and achieve your goal.
CJC-1295 with or without DAC, How to work?
CJC-1295 without/+ DAC is a peptide supplement that can stimulate the anterior pituitary to release more growth hormone, both peptide works by stimulating growth hormone secretion by binding to GHRH receptors and should stimulate the secretion of the whole family of growth hormone peptides normally secreted by the pituitary gland. These hormones will stimulate increases in bone density and collagen production, as well as boosting the immune system, leading to stimulate the production of lean muscle mass.[3][4]
CJC-1295 with DAC can be combined with growth hormone releasing peptides for enhanced peptide cycling results. CJC-1295 DAC is commonly paired with growth hormone replacement peptide (GHRP) 6 or GHRP-2. Combined use of CJC-1295 DAC with GHRP’s will accelerate fat loss and weight loss and stimulate anabolic effects via growth hormone induced fat breakdown. Overall, CJC-1295 with DAC will stimulate protein synthesis and fuel the growth of lean muscle tissue. The peptide also promotes faster injury recovery, a reduction in body fat and increased muscle mass. The growth stimulatory properties of CJC-1295 DAC will also stimulate cell growth and division to improve skin health, healing and immune system function.[15]
CJC 1295 without DAC is a peptide hormone made of amino acid, can increases lean muscle mass, boost muscle strength and losesbody fat, the only difference to other growth hormones on the market, CJC-1295 no DAC have an extended lifespan, can last longer in your body to increase the growth hormones dispersal rate.
CJC-1295 with or without DAC, what’s the benefit?
CJC-1295 with or without DAC have the same benefits, following include but are not limited to:
Increasing Bone Density: CJC-1295 w/no DAC can increase bone density, to reduce the risk of fractures and promote overall bone health.[13][14]

How To Use CJC-1295 with or without DAC?
CJC-1295 + DAC and CJC-1295 without DAC (also known as Modified GRF 1-29) are both Growth Hormone Releasing Hormones (GHRH), they work same function in the human body. Both via subcutaneous injection (above the muscle, below the skin) in the stomach or abdominal regio. CJC-1295 without DAC usually be taken once daily, it also have a recommend plan“5 days a week”, either with skipping days every 2 or 3 days, or weekdays on, weekends off for injections. But in both cases, the effects of CJC-1295 – higher circulating levels of human growth hormone – tend to last for upwards of a week following administration and continue at that level so long as the administration continues a few times a week.[5][6]
What are the side effects of CJC-1295 with or without DAC?
Generally, the use of CJC 1295 with or without DAC is safe under correct dosage and properly administered, and if any side effects, that are usually mild.
The most common side effects include:
Sensitivity at the injection site
mild soreness or pain
Headache
Dizziness
nausea
fatigue
drowsiness
flushing, hives, or other skin reactions
Hyperactivity
hard to swallow
However, if any symptoms persist then you may want to consult your doctor.
CJC-1295 with DAC vs CJC-1295 without DAC, What’s the Difference?
Half-life For CJC-1295 vs CJC-1295 DAC
CJC-1295 without DAC is closer to the body’s own peptide, it can use to work same way in the body. Like GHRH, the half-life of CJC-1295 without DAC is very short, about 30 minutes.
While, CJC-1295 + DAC has a half-life that can last up to approximately 6~8 days. It allows the peptide to better bind to the protein albumin in the blood, leading to have an effect for a long time.[8][10]
Dosage For CJC-1295 vs CJC-1295 DAC
Another big change between CJC 1295 with and without DAC is the dose difference. When it has the DAC added in, you’re looking at between 1000mcg and 2000mcg per dose. However, when looking at CJC 1295 without DAC, these doses are much smaller at 100mcg per dose and can be taken up to three times in a day, making your daily dose 300mcg.
Effect For CJC-1295 vs CJC-1295 DAC
CJC-1295 with and without DAC almost have same effect. However, CJC-1295 DAC is sometimes used for burns or for significant soft-tissue, it helps the body repair these types of tissues after some surgeries. It may be one additional application of CJC-1295 DAC beyond the uses that the two have in common (which are building muscle, burning fat, anti-aging effects, and better sleep).[7][9]
CJC-1295 DAC & Ipamorelin
CJC-1295 DAC and ipamorelin are often combined therapy because they are known to work well together. CJC-1295 takes 1-4 hours to reach peak serum levels in the blood, whereas ipamorelin acts much faster. Ipamorelin has a half-life of about 2 hours, so it is cleared from the body more quickly. The combination of the two peptides ensures the rapid onset of action of ipamorelin and the long-lasting effect of CJC-1295 DAC. These two peptides are incredibly specific in increasing growth hormone levels compared to other peptides. Other peptides can increase cortisol levels (as seen with stress, which can increase hunger), but neither ipamorelin nor CJC-1295 had an effect on the other hormones, which is a big plus.

The reason why CJC1295 possesses the ability to lengthen the half-life within the active agent has to do with the scientific process known as bioconjugation. This technology, which is relatively new in nature, is defined by its ability to take a reactive group and bond it to a peptide (Aslam and Dent). This attachment causes a reaction with a nucleophilic unit; a typically partially molecule that is found within the bloodstream of an animal test subject. This reaction in turn causes a more stable bond to occur. This specific peptide has an especially high attraction to albumin, a globular protein that is soluble in water. This affinity prohibits natural degradation, which in turn increases the peptide’s half-life (Hermanson). Additionally, clinical research performed on animal test subjects has thus far shown that there have been no signs of DPP-IV degradation present when CJC-1295 was introduced (Gonzalez, US Peptide Articles).

CJC-1295 Overview
Growth hormone-releasing hormone (GHRH) has undergone several modifications to create analogs that retain certain effects while eliminating others. Among these modifications is CJC-1295, which encompasses the first 29 amino acids of GHRH. CJC-1295, technically a maleimido derivative of hGRF(1-29), was developed to enhance solubility as a growth hormone secretagogue and facilitate large-scale production while maintaining the physiological actions of GHRH.[1][2][3]
CJC-1295 Versus CJC-1295 DAC
CJC-1295 is a derivative of the initial 29 amino acids of growth hormone-releasing hormone (GHRH), making it structurally akin to other GHRH analogs such as Sermorelin. Although it bears the greatest resemblance to modified GRF (1-29), the two peptides are not identical. Much confusion arises due to the peptide’s similarities with others and the inclusion of a supplementary chemical compound known as the drug affinity complex (DAC) in the original formulation of CJC-1295.

Half-life of CJC-1295-DAC compared to standard growth hormone releasing factor (GRF)
Authoritative source:Oxford Academic
Initially, ConjuChem Biotechnologies, the creator of DAC, labeled the peptide with DAC as CJC-1295. However, this caused confusion as the peptide was also available without DAC. To alleviate this confusion, the version of CJC-1295 that includes DAC is now referred to as CJC-1295-DAC, while the version without DAC is simply called CJC-1295 or CJC-1295-no DAC.

CJC-1295 Research
CJC-1295 and Growth Hormone Release
Being a derivative of GHRH, it is expected that CJC-1295 stimulates the secretion of GH. Research indicates that a single dose of CJC-1295 can increase GH levels in mice by 2-10 times.[5][6][7] The highest GH levels are typically observed around 2 hours after administration, and the effects can last for approximately six days. Unlike other GH secretagogues, CJC-1295 maintains the natural physiological pattern of GH release. This means that the regular circadian peaks and troughs in GH secretion are preserved, making CJC-1295 a physiologically relevant growth hormone-releasing factor.
Preserving physiologic release of GH even while influencing the maximum concentration of the hormone in the bloodstream is critical to ensuring enhanced effects without increased side effects. In particular, CJC-1295 has been demonstrated to preserve growth hormone’s physiologic effects on hyperplasia, hypertrophy, bone density, blood sugar, fat metabolism, protein synthesis, and myocardial (heart cell) function.
CJC-1295 and Growth
Studies conducted on mice lacking normal GHRH physiology have demonstrated that CJC-1295 maintains the regular release of GH. This characteristic of the peptide holds potential for therapeutic applications in addressing abnormal growth in various mammalian species, including humans. Preserving the natural pulsatile release of GH is crucial in ensuring the appropriate secretion of downstream hormones, such as insulin-like growth factor-2 (IGF-1).

Research conducted in the early 1990s suggests that CJC-1295 and other GRF analogues could potentially be beneficial in promoting ovulation in infertile female patients. It has been well-established that ovulation is dependent on IGF-1 and likely influenced by GH release and cycling. Animal studies focusing on superovulation have further supported these theories by demonstrating significant increases in both GH and IGF-1 levels during the ovulation period. Moreover, these studies indicate that the administration of exogenous GH secretagogues, such as CJC-1295, is sufficient to induce proper ovulation.[5][6] There is also speculation that CJC-1295 and similar analogues might have potential applications in male infertility by aiding in the regulation of sperm production, although this hypothesis has yet to be tested.
CJC-1295 Summary
CJC-1295 is a growth hormone secretagogue specifically designed to have a prolonged plasma half-life and to preserve the natural patterns of the GH axis. It has proven successful in achieving these goals. While the molecule initially generated limited interest in research settings due to the emergence of similar compounds and its proprietary nature, the ability to manufacture CJC-1295 more freely is likely to reignite curiosity in its properties, especially regarding its potential applications in addressing the challenging issue of human infertility.
In studies conducted on mice, CJC-1295 has demonstrated moderate side effects, low oral bioavailability, and excellent subcutaneous bioavailability. However, it is important to note that the dosage per kilogram used in mice is not directly applicable to humans. Consequently, the sale of CJC-1295 by Peptide Sciences is strictly limited to educational and scientific research purposes and is not intended for human consumption. Therefore, purchasing CJC-1295 is only appropriate for licensed researchers. [6][7]
