CJC-1295 is a synthetic peptide that has gained significant attention for its ability to increase growth hormone (GH) levels. But to understand its potential, you first need to master the specifics of CJC 1295 dosage and timing. Getting this right is the difference between an effective protocol and a waste of time and money. This guide breaks down the science, the community-tested protocols, and what you need to discuss with your provider in 2026.

We'll cover the two main forms of CJC-1295, how they are stacked with Ipamorelin, and the protocols used for goals ranging from anti-aging to bodybuilding.

An Introduction to CJC-1295

CJC-1295 is a synthetic analogue of growth hormone-releasing hormone (GHRH). In simple terms, it signals your pituitary gland to produce and release more of your own natural growth hormone. You can learn more about the basics in our complete guide to what peptides are.

The most important thing to understand about CJC-1295 is that it comes in two distinct versions:

1. CJC-1295 without DAC (also known as Mod GRF 1-29): This is a short-acting version. It causes a sharp, quick pulse of growth hormone that mimics the body's natural patterns.
2. CJC-1295 with DAC (Drug Affinity Complex): This is a long-acting version. The DAC modification allows the peptide to bind to a protein in the blood called albumin, dramatically extending its life in your system.

This single difference—the presence or absence of the DAC—completely changes the approach to dosage and timing. Most modern protocols, especially those focused on wellness and anti-aging, favor the short-acting version (without DAC) and stack it with another peptide called Ipamorelin to create a powerful, synergistic effect.

Dosing CJC-1295 Without DAC (Mod GRF 1-29)

CJC-1295 without DAC, often called Mod GRF 1-29, is the more popular choice for those seeking to replicate the body's natural GH secretion rhythm. Its primary characteristic is a very short half-life, estimated to be around 30 minutes (ThePeptideGuides).

Because it clears from the body so quickly, it requires more frequent injections to be effective. A single injection creates one "pulse" of growth hormone release. This pulsatile action is considered more physiological, closely resembling how the body naturally releases GH throughout the day and in a large surge during sleep.

A typical CJC 1295 no dac dosage bodybuilding protocol or an anti-aging protocol often involves:

• Dose: 100 mcg per injection.
• Frequency: One to three times per day.

The injections are best administered on an empty stomach to ensure nothing interferes with the GH pulse. Optimal times include:

• In the morning, at least 30-60 minutes before your first meal.
• Post-workout, to aid in recovery.
• Before bed, which is considered the most crucial injection. This dose amplifies the large, natural GH pulse that occurs during the first few hours of deep sleep (ThePeptideGuides).

This version is almost always used in combination with a GHRP (Growth Hormone Releasing Peptide) like Ipamorelin. The combination provides a synergistic effect that we will explore in a later section.

Understanding CJC 1295 Dosage and Timing with DAC

CJC-1295 with DAC is a different chemical entirely in terms of its action in the body. The Drug Affinity Complex allows it to bind to albumin, a protein in your blood, which protects it from rapid degradation. This gives it an extended half-life of about 6-8 days (PeptideDosingProtocols).

This long half-life means the CJC 1295 dosage and timing is much simpler:

• Dose: 1,000 to 2,000 mcg (1 to 2 mg) per week.
• Frequency: Injected once or twice weekly.

While this is far more convenient, it produces a very different effect. Instead of creating short, naturalistic pulses of growth hormone, CJC-1295 with DAC creates a sustained elevation of GH and IGF-1 levels around the clock. This is often referred to as a "GH bleed."

Clinical studies confirmed this effect. One pilot study showed that a single injection of CJC-1295 with DAC increased average GH levels by 2- to 10-fold for at least six days and IGF-1 levels by 1.5- to 3-fold for 9 to 11 days (PeptideDosingProtocols, PeptideMark).

However, some practitioners believe this constant elevation is less physiological than the pulsatile release of Mod GRF 1-29 (ThePeptideGuides). Furthermore, research into CJC-1295 with DAC was discontinued. A Phase 2 clinical trial was halted in 2006 (PeptideDosingProtocols). It's important to know that during one 12-week trial, a participant passed away from a myocardial infarction. The attending physician believed it was unrelated to the study drug and likely due to pre-existing conditions, but it's a critical detail to be aware of when discussing options with your provider (FDA-2024-N-4777-0002).

Because of these factors, CJC-1295 with DAC is used less commonly in clinical settings today compared to the Mod GRF 1-29 and Ipamorelin combination.

The Perfect Pair: A Guide to CJC 1295 Dosage and Timing with Ipamorelin

The most common and arguably most effective way to use CJC-1295 (without DAC) is by stacking it with Ipamorelin. This combination is a cornerstone of modern peptide therapy for anti-aging.

CJC-1295 is a GHRH, and Ipamorelin is a GHRP (Growth Hormone Releasing Peptide) and a ghrelin mimetic. They work together synergistically:

• CJC-1295 (GHRH): Tells the pituitary gland how much growth hormone to release.
• Ipamorelin (GHRP): Tells the pituitary gland to release the growth hormone.

This dual-receptor action results in a stronger, more effective GH pulse than either peptide could achieve on its own. It's also highly specific, meaning it releases GH without significantly affecting other hormones like cortisol or prolactin, which is a major benefit over older peptides.

Standard Dosing Protocols for the Stack

The cjc-1295 ipamorelin stack dosage is typically a 1:1 ratio, administered via subcutaneous injection.

• Dose: 100 mcg of CJC-1295 (no DAC) combined with 100 mcg of Ipamorelin per injection.
• Frequency: One to three times per day.
• Timing: Always on an empty stomach (at least one hour after eating, but preferably two hours). The most critical dose is 30-60 minutes before bed to work with the body's largest natural GH release (CalcMyPeptide).

For an individual weighing around 220 lbs (100 kg), this 100 mcg dose of Ipamorelin aligns with its saturation dose of 1 mcg per kg of body weight. Dosing beyond this point is unlikely to produce a greater GH release (CalcMyPeptide).

Cycling the CJC-1295 and Ipamorelin Stack

To prevent receptor desensitization, providers typically recommend cycling this peptide stack. A common protocol is:

• Weekly Cycle: Injecting 5 days on, followed by 2 days off.
• Long-Term Cycle: Following a therapy cycle of 1 to 3 months, followed by an "off" period of at least one month (Perfect B).

This gives your pituitary receptors a break and helps maintain sensitivity to the peptides over the long term.

Reconstitution, Cost, and Finding a Provider

Before you can think about injections, you need to understand three practical aspects: reconstitution, cost, and where to get these peptides safely.

CJC-1295 Ipamorelin Reconstitution and Dosage

CJC-1295 and Ipamorelin usually come in a lyophilized (freeze-dried) powder in a vial. This powder must be reconstituted with bacteriostatic water before it can be injected. This process involves carefully adding a specific amount of water to the vial to create a solution of a known concentration.

For example, if you add 3 mL of bacteriostatic water to a 5mg vial of peptide, you get a concentration of roughly 166.6 mcg per 0.1 mL (or "10 units" on an insulin syringe). Correctly calculating this is key to accurate dosing.

To simplify this, you can use our free peptide reconstitution calculator. You can also learn more about general injection techniques in our guide on where to inject peptides.

What is the CJC-1295 Ipamorelin Cost?

The cjc-1295/ipamorelin cost can vary significantly. It depends on the dosage, the duration of therapy, and the source. When prescribed by a licensed provider from a reputable compounding pharmacy, you can expect the cost to be anywhere from $250 to over $600 per month.

While you might see these peptides advertised for much less on "research chemical" websites, purchasing from these sources for personal use is extremely risky. There is no guarantee of purity, sterility, or even that the vial contains the correct substance. The only safe way to obtain these compounds for therapeutic purposes is through a licensed medical provider. For a deeper look at expenses, see our article on peptide therapy costs.

Where to Buy CJC-1295 and Ipamorelin

This brings us to the most important question: cjc-1295 ipamorelin where to buy? Because CJC-1295 is not an FDA-approved drug, you cannot get it from a normal pharmacy. It's currently classified as an investigational compound (PeptideClinicLocator).

The cjc-1295 ipamorelin best place to buy is through a specialized hormone optimization or peptide therapy clinic. These clinics can legally prescribe these peptides, which are then made for you by a licensed compounding pharmacy. This ensures you are receiving a pure, accurately dosed product under medical supervision.

Telehealth has made this process simple. You no longer need to search for "cjc-1295/ipamorelin near me." You can connect with online peptide clinics that serve your state.

What to Consider Before Starting

Deciding to explore peptide therapy is a significant step. The key takeaway regarding CJC 1295 dosage and timing is that there is no single right answer. The best protocol for you depends on your goals, your biology, and your lifestyle.

The choice between CJC-1295 with DAC and without DAC is a clear example. Do you prefer the convenience of one injection per week with a constant GH elevation, or do you prefer the more natural, pulsatile approach that requires daily injections? This is a critical conversation to have with your provider.

Self-dosing based on internet forums is not a sound strategy. Working with a qualified provider ensures your protocol is based on lab work, tailored to you, and uses high-quality peptides from a trusted source.
