What Is Ipamorelin?

Ipamorelin is a selective growth hormone-releasing peptide (GHRP) that stimulates the pituitary gland to release growth hormone in a pulsatile, physiologic pattern. It binds to the ghrelin receptor (GHS-R1a) and is notable for its clean side-effect profile, as it does not significantly elevate cortisol, prolactin, or appetite hormones at standard doses .

Because dosing directly affects both efficacy and tolerability, understanding ipamorelin dosing principles is essential for anyone considering this peptide. This guide is intended to provide educational context. Your physician will determine the appropriate dose for your specific situation.

Ipamorelin is not FDA-approved for any medical condition. All dosing information below reflects published research, clinical protocols, and established practice patterns rather than FDA-approved prescribing information.

Standard Ipamorelin Dosing Protocols

Typical Dose Range

In clinical studies and practice, ipamorelin is typically dosed between 100 mcg and 300 mcg per injection. The most common protocol uses 200 to 300 mcg per injection .

In the published human research, doses ranging from 1 mcg/kg to 30 mcg/kg have been studied. A dose of approximately 1 mcg/kg was identified as the threshold for significant GH release, with higher doses producing proportionally greater GH output up to a ceiling effect .

Injection Frequency

Ipamorelin is most commonly administered one to three times per day:

• Once daily (most common): A single injection before bedtime is the most widely used protocol. This timing takes advantage of the body's natural nocturnal GH pulse and can enhance deep sleep quality.
• Twice daily: Some protocols add a morning injection (upon waking, before eating) to the evening dose. This approach aims to more closely replicate the body's natural pattern of multiple daily GH pulses.
• Three times daily: Less common, this protocol adds a third injection around mid-afternoon. It is sometimes used in protocols focused on recovery from injury or surgery, or for more aggressive body composition goals.

Starting Dose Recommendations

Most physicians recommend starting at the lower end of the dosing range and titrating upward based on response and tolerability:

• Conservative start: 100 mcg once daily before bed for the first 1 to 2 weeks
• Standard escalation: Increase to 200 mcg once daily, then consider adding a second injection if warranted
• Full protocol: 200 to 300 mcg, one to two times daily, based on goals and physician guidance

Starting low helps minimize initial side effects like headache and water retention while allowing the body to adapt to increased GH activity.

Timing Considerations

Relation to Meals

Timing relative to food intake matters significantly with ipamorelin. Elevated blood sugar and insulin levels blunt the GH response to ipamorelin. For this reason, injections should be given on a relatively empty stomach .

General guidelines:

• Wait at least 30 minutes after injection before eating
• Wait at least 90 minutes after eating before injecting (ideally 2 hours)
• Avoid high-carbohydrate or high-fat meals immediately before injection

Best Time of Day

The most common injection times and their rationale:

• Before bed (most popular): Amplifies the body's largest natural GH pulse, which occurs during the first 90 minutes of deep sleep. This timing can also improve sleep quality.
• Morning (fasted): GH has lipolytic (fat-burning) effects, and morning dosing during the fasted state may enhance this benefit. Wait 30 minutes before eating breakfast.
• Post-workout: Some protocols include a post-training injection to support recovery. Ensure at least 30 minutes have passed since any intra-workout nutrition.

Timing with CJC-1295

Ipamorelin is frequently combined with CJC-1295 (a GHRH analog) for synergistic GH release. When used together, both peptides are typically drawn into the same syringe and injected simultaneously. The combined dose does not require adjusting the individual peptide doses in most protocols .

Cycling Protocols

Whether to cycle ipamorelin is a topic of ongoing discussion among clinicians. There are two main approaches:

Continuous Use

Some physicians prescribe ipamorelin for continuous daily use, reasoning that because it works with the body's own feedback mechanisms (rather than introducing exogenous GH), it does not suppress natural GH production or cause receptor desensitization in the same way that exogenous HGH might.

Cyclical Use

Other clinicians prefer a cycling approach, typically:

• 5 days on, 2 days off (weekdays on, weekends off)
• 12 weeks on, 4 weeks off
• 6 months on, 1 month off

The rationale for cycling includes maintaining receptor sensitivity and allowing the pituitary to demonstrate independent function. There is limited published data definitively proving one approach superior to the other for ipamorelin specifically.

Your physician will recommend a cycling strategy based on your goals, lab work, and individual response.

Reconstitution and Preparation

Ipamorelin is typically supplied as a lyophilized (freeze-dried) powder in a sterile vial. It must be reconstituted with bacteriostatic water before injection.

Standard Reconstitution Steps

1. Remove the flip-off cap from the ipamorelin vial and wipe the rubber stopper with an alcohol swab
2. Draw the desired amount of bacteriostatic water into a syringe (common amounts: 2 mL or 2.5 mL)
3. Insert the needle into the vial at an angle and allow the water to flow gently down the inside wall of the vial. Do not squirt directly onto the powder, as this can damage the peptide
4. Gently swirl the vial until the powder is fully dissolved. Do not shake vigorously
5. The reconstituted solution should be clear. If it is cloudy or contains particles, do not use it

Calculating Your Dose

The concentration of your reconstituted solution depends on the amount of peptide in the vial and the amount of water added. For example:

• 5 mg vial + 2 mL bacteriostatic water = 2.5 mg/mL (250 mcg per 0.1 mL or 10 units on an insulin syringe)
• 5 mg vial + 2.5 mL bacteriostatic water = 2 mg/mL (200 mcg per 0.1 mL or 10 units on an insulin syringe)

Your physician or pharmacy will provide specific reconstitution and dosing instructions. When in doubt, ask before injecting.

Storage

• Before reconstitution: Store in a cool, dry place. Refrigeration is recommended but not always required for short-term storage. Avoid heat and direct sunlight.
• After reconstitution: Refrigerate at 36 to 46 degrees Fahrenheit (2 to 8 degrees Celsius). Use within 4 to 6 weeks. Do not freeze reconstituted peptide.

Dosing by Goal

While individual dosing should be determined by your physician, here are general protocol patterns based on common goals:

Anti-Aging and General Wellness

100 to 200 mcg once daily before bed. This conservative approach aims to restore more youthful GH pulsatility without aggressive dosing. Learn more in our Ipamorelin for anti-aging guide.

Body Composition (Fat Loss and Lean Mass)

200 to 300 mcg, one to two times daily (morning and evening). The morning fasted dose targets lipolysis, while the evening dose supports recovery and sleep.

Recovery from Injury or Surgery

200 to 300 mcg, two to three times daily for a defined period. Higher frequency dosing may be used temporarily to maximize GH-mediated tissue repair. See our Ipamorelin for muscle recovery guide.

Sleep Optimization

200 to 300 mcg once daily, 30 to 60 minutes before bed. Single evening dosing is typically sufficient for sleep-focused protocols.

Safety and Side Effects

Ipamorelin is considered one of the best-tolerated GHRPs. Side effects are generally mild and dose-dependent. Common reports include mild headache (especially initially), transient flushing, water retention, and injection site irritation.

Starting at a lower dose and titrating gradually is the most effective way to minimize side effects. If you experience persistent or concerning symptoms, contact your physician promptly.
