Dosage & Cycling30-60 mcg per kg of body weight, injected once a week, 12-week cycles with a one-month break
Side EffectsRare, potential for vertigo, increased body temperature, mood swings, anxiety, nausea, flu-like symptoms, hives
Common StacksCJC-1295 / Ipamorelin, CJC-1295 / GHRP-2

CJC-1295 constitutes 30 amino acids in its structure and is one of the potent analogs of growth hormone-releasing hormone (GHRH) and an effective growth hormone (GH) secretagogue (1).

The peptide was initially synthesized by ConjuChem Technologies after several modifications of its predecessor, Sermorelin Acetate. 

CJC-1295 occurs in two primary forms, with or without Drug Affinity Complex (DAC). CJC-1295 with DAC is considered to have a greater bioavailability and half-life than regular CJC-1295 due to its binding capability to a blood protein.

With its potent binding to endogenous albumin, CJC-1295 takes more than 6-10 days to clear from the body; therefore gets more time to exert its effects (2)

Several studies have been conducted to evaluate the efficacy and potency of CJC-1295. 

Now I am sure you all must have had confusion about CJC-1295 and Ipamorelin because they are almost always used together.

Let me make it clear for you guys. Both of them are DIFFERENT peptides. While the mechanism of action is slightly different, the effects produced are pretty similar, and only for that reason, the majority of people stack both peptides. 

How Does CJC-1295 Work?

I strongly believe that you should know the working mechanism of the peptide before really using it. With CJC-1295, it’s an easy one to grasp. 

CJC-1295, an analog of GHRH, binds to the receptors on the anterior pituitary gland. From there, they stimulate the release of Growth Hormone (GH) and Insulin-like growth factor-1 (IGF-1) (3). 

Fig 1. Effects of CJC-1295 in GH knockout mouse

Research suggests a very similar mechanism of action associated with Sermorelin. However, unlike Sermorelin, which causes a more pulsatile release of Growth Hormone, CJC-1295 triggers a more drastic release. 

Experiments have revealed that CJC-1295 can cause a 200-1000% increase in the body’s GH levels. Importantly, the levels remain up for more than 6 days, thus inducing pronounced effects overall.  

Benefits of CJC-1295 

CJC-1295 supplementation is associated with a wide array of benefits. Since the peptide works via the release of Growth Hormone and IGF-1, you can already expect a long list of effects! 

Increase in Lean Muscle Mass:

One of the BIGGEST advantages you can gain through CJC-1295 is an increase in lean muscle mass (4). The peptide does this via an increase in muscle protein synthesis and mass growth.

The CJC-1295 and Ipamorelin stack offers a more significant increase in muscle growth and strength.

Triggers Fat Loss:

Other than that, CJC-1295 is widely known for its fat-loss attributes (5). Prolactin, another hormone secreted by the anterior pituitary, is associated with slowing the body’s metabolism.

This is soon followed by a more significant visceral fat accumulation, one of the major risk factors for cardiovascular diseases.

However, with CJC-1295, you’re in safe hands! The peptide slows the release of prolactin and contributes to the rapid loss of unwanted fat. 

May Improve Sleep Cycle

Although limited studies are available, some scientists do claim CJC-1295 is involved in sleep improvement. Since GHRH is seen to promote deep and quality sleep, it makes sense that, being a GHRH analog, CJC-1295 does the same.

With better sleep, your body gets a chance to repair tissue, make more neural connections, and cause an increase in muscle and bone density. 

This is always a tricky one to answer when it comes to peptides. 

As for now, the FDA is yet to approve the peptide for human consumption. However, one can purchase it via online vendors for research purposes. 

Nonetheless, as for other countries, the laws differ widely. 

Dosage & Cycling

It is suggested that 30 to 60 mcg per kg of body weight should be more than enough. Since CJC-1295 has a longer half-life, injecting it once a week is generally recommended.

Moreover, It would be best if you intake the peptide before going to bed. 

After cycling it for twelve weeks, one should follow a regimen of a month-long break from all kinds of peptides. 

You can view our comprehensive chart available to learn more about specific dosage and cycling guidelines. 

Side Effects of CJC-1295 

CJC-1295, a synthetic analog of growth hormone-releasing hormone (GHRH), is generally well-tolerated by most users, but like any compound, it can be associated with specific side effects. 

It’s crucial to be aware of these potential adverse reactions to ensure a safe and effective experience with this peptide.


Vertigo, a condition characterized by a spinning or dizziness sensation, is a rare side effect associated with CJC-1295 use. 

While not everyone will experience vertigo, those who do may find it disorienting and uncomfortable. The occurrence of vertigo is more likely when users take higher doses or are new to using the peptide.

To minimize the risk of vertigo, it’s advisable to start with lower doses of CJC-1295 and gradually increase the dosage as needed. 

Following recommended dosing guidelines and cycle durations can significantly reduce the likelihood of experiencing this side effect. 

Additionally, maintaining proper hydration and ensuring a balanced diet may help alleviate vertigo symptoms.

Increased Body Temperature

An increase in body temperature is another potential side effect that some individuals may encounter with CJC-1295 supplementation. 

This side effect is more commonly observed in beginners or those who take higher initial doses. The elevated body temperature can lead to sensations of warmth and sweating.

To manage the risk of increased body temperature, individuals are encouraged to start with conservative doses and carefully monitor their body’s response. 

It’s essential to pay attention to any signs of discomfort and make adjustments accordingly. Adequate hydration and maintaining a comfortable room temperature can also contribute to managing this side effect.

Mood Swings

Mood swings, which may manifest as changes in emotional stability, are another potential side effect of using CJC-1295. 

Some individuals may experience feelings of irritability, emotional sensitivity, or even depressive episodes. These mood-related side effects are relatively rare but can be disruptive when they occur.

To address mood swings, open communication with a healthcare provider is crucial. Adjusting the peptide’s dosage and cycle duration, and addressing any underlying emotional concerns, may help manage these mood-related side effects. 

Leading a positive and balanced lifestyle, which includes regular exercise and stress management techniques, can also contribute to emotional stability.


Heightened anxiety is a possible side effect associated with CJC-1295 usage. Anxiety can manifest as feelings of restlessness, nervousness, or unease. 

While not everyone will experience anxiety, it’s essential to monitor your emotional state during CJC-1295 use.

To manage anxiety, individuals may consider consulting a mental health professional or psychiatrist. 

They can provide strategies and, if necessary, medications to address anxiety symptoms. Adjusting the dosage or cycling pattern of CJC-1295 may also help alleviate anxiety in some cases.

Nausea and Flu-Like Symptoms

Nausea and flu-like symptoms are potential side effects that can occur with CJC-1295 supplementation. 

Nausea presents as a queasy feeling or a tendency to vomit, while flu-like symptoms may include fatigue, muscle aches, and a general sense of malaise. These side effects are generally mild but can be discomforting.

To reduce the likelihood of nausea and flu-like symptoms, it’s advisable to start with low doses of CJC-1295 and gradually increase the dosage as needed. Administering the peptide in a clean and sterile manner can help prevent these side effects. 


Hives, also known as urticaria, can occasionally occur as a side effect of CJC-1295 use. Hives manifest as itchy, raised, and red welts on the skin. While hives are generally not severe, they can be uncomfortable and bothersome.

If hives occur, it’s essential to discontinue the use of CJC-1295 and consult with a healthcare provider. They can recommend antihistamines or other treatments to alleviate hives and prevent their recurrence. 

Identifying any potential allergic reactions to the peptide is crucial for ensuring a safe and positive experience.

Who should use CJC-1295?  

After the age of 30, the body’s ability to synthesize and release Growth hormone declines naturally. This is accompanied by slow healing, weakness, and fatigue-like symptoms. 

Since CJC-1295 increases the body’s natural production of GH, it’s best to supplement after age 30 to raise and fasten metabolism. 

Forms of CJC-1295 

CJC-1295 comes in the form of powder. Therefore, it must be reconstituted with bacteriostatic water before ingesting. After doing so, it can be administered through subcutaneous injection.

To know the detailed procedure on how to reconstitute peptides, you may read the reconstitution guide on the website. 

User Reviews and Experiences 

Customer/User reviews are a real deal since they tell you so much about a peptide you would not otherwise know! 

Let’s dive into some of the Reddit reviews and see what we can make of them. 

β€œI’ve been using it for 2 weeks already. Besides a slight burn sensation in the administered area for a while. I’m not losing muscle mass, and my joints feel stronger.”

One of the users said this about CJC-1295

β€œ I’ve been on CJC-1295 since April. I’ve lost roughly 40lbs and maintained most of my muscle. I do jitsu 2-3 times a week, kettlebell circuits 2x a week and a heavy squat session 1x per week. I eat chicken, tuna, and steak with salad or small fruit. I sleep better now. I also have been on TRT for about 10 years. I did notice my free test and bound both values shot up to the higher thresholds even with reducing my weekly test protocol to 50mg x2 a week sub q.

Another one shares his experience by saying

β€œI found it amazing. I’m very lean to begin with but my strength went through the roof, pumps at the gym were amazing and overall got much more lean. Maybe gained 3-5lbs of muscle but the most noticeable difference was how much my veins just popped out of my arms and shoulders. Again, lean and vascular to begin with but In my opinion I had amazing results. Running it back for a second time in about two weeks. Took about 3 weeks to kick in”.

CJC-1295 Stacks 

One of the best ways to get enhanced benefits with lower doses is to stack peptides together. Generally, SARMs are seen to be stacked together for maximum benefits. However, research now suggests the same for peptides too. 

If you have been in the peptide industry for some time, you would have surely heard about CJC-1295 and Ipamorelin together, and perhaps this is one of the most popular stacks. 

Both peptides together trigger a significant release of growth hormone (GH)  in the human body. This allows the body to speed up the process of repair and healing.

Research also indicates improved outcomes like increased lean muscle mass and fat loss. 

Although, both of these peptides differ significantly when it comes to their mechanism of action. CJC-1295 works by acting as an analog of GRHR and GH secretagogue.

At the same time, Ipamorelin works by acting as an agonist for Ghrelin receptors. 

When cycling with these peptides, you must ensure the intake of 150 mcg of Ipamorelin and 150 mcg of CJC-1295. 

Where to Buy CJC-1295?

With so much market and competition in the peptide industry, it is extremely important to pick the right vendor that specializes in selling authentic peptides at nominal costs. Perhaps BioTech peptides is one of the top options I would recommend! 

CJC 1295 Overview

CJC 1295

CJC 1295 is considered one of the potent growth hormone secretagogues (GHS). 

The peptide was first developed to stimulate the natural production of growth hormone and IGF-1 from the anterior pituitary gland. CJC 1295 also provides an inhibitory effect on the release of somatostatin, an inhibitor of growth hormone. 

These hormones aid in increasing lean body mass, endurance, and strength. Researchers also believe that CJC 1295 is capable enough to regulate sleep cycles. Evidence suggests that growth hormone secretagogues such as CJC 1295 play an important role in maintaining and improving cardiovascular function, wound healing and repair, increased protein synthesis, and much more. 

For bodybuilders, it is recommended to stack CJC 1295 with Ipamorelin to gain maximized benefits. Nonetheless, if you’re a beginner, you might experience unpleasant side effects such as vertigo, increased body temperature, and mood swings.

CJC-1295 vs. Sermorelin

Both CJC-1295 and Sermorelin are more and less similar. Sermorelin was first synthesized by ConjuChem Technologies and is considered the predecessor of CJC-1295. 

Both of these peptides work by stimulating GHRH receptors on the anterior pituitary, thereby increasing the release of growth hormones in the human body. 

Nonetheless, there’s always a catch. Of the two peptides, Sermorelin provides a somewhat more natural ebb and flow of Growth hormone since it is cleared faster than CJC-1295.

That means, during the given period, it is more likely for CJC-1295 to be present and stimulate the release of GH than Sermorelin. 

CJC-1295 vs. Mod Grf-129

These are essentially the same peptides, differing slightly in composition, thus making all the difference in efficacy. CJC-1295 differs from Modified Grf-129 due to the presence of a Drug Affinity Complex (DAC). 

Sermorelin and Mod Grf-129 have a very short half-life of approximately 30 minutes compared to CJC-1295, having a half-life of 8 days. Due to the fact of DAC, CJC-1295 can bind with endogenous albumin. 

Does CJC-1295 Really Work?

For sure! 

CJC-1295 is user-friendly and has to offer a lot if used rightly! 

It has tremendous beneficial effects, such as increased muscle mass and fat loss, promotes deep sleep, and provides a better life. 

Perhaps what separates it from other peptides is that this peptide doesn’t have any adverse side effects and is comparatively much safer for human consumption than others.

Hi, I’m a little confused: in the beginning of the article you say 30-60 mcg of CJC-1295 per Kg of bodyweight once a week. Later on you say Typical dosage: 250-300mcg- but for a 175lb man that’s 2,370 mcg (30mcg X 79kg= 2370mcg). Can you explain?
Also, with the CJC-1295 needing reconstitution, what is the proper dilution for 5mg of CJC-1295 and Bacteriostatic water?
Thank you,

Reply to  Bill Grinley

The standard testing dosage administered in the subjects is usually per kg of body weight whenever a peptide or any drug of intake is studied in the clinical trials to determine the actual efficacy and potency. Because peptides never make it to the last stage of clinical trials due to lack of FDA approval, no fixed dosage is decided. Therefore, most people use the trial and error method and decide on a standard dosage of peptides that works optimally for most users; in this case, that’s 250-300mcg.

CJC/IPA a 5/5 blend we are researching and started off with 250- husband felt fine I felt terrible. Do I need a different dose than him? He weighs 250 I weigh 150- however I cant seem to find any info on weight for this blend.
3ml of water 250 pulled to 15 on 1ml syringe. I tried that the first night and second night I did 200 and still felt tight chest. Where can you get proper info on the blend and what to dose at

I had a question about dosing. In the article (and question asked above) it recommended to take CJC once a week, but in the dosage chart on your site, it says to take CJC 150mcg / day, and also the Ipamoreline 150mcg / day. So do I do them daily or weekly? Thanks in advvance.

It is suggested that 30 to 60 mcg per kg of body weight should be more than enough. Since CJC-1295 has a longer half-life, injecting it once a week is generally recommended.
So for 73 kilograms should the dose be 73 x 30 mcg?
