Ipamorelin Dosage Schedule

A comfortable, well tolerated starting point for growth hormone support before working up toward the full ceiling dose. A good place to begin if you're new to Ipamorelin.

Ipamorelin Standard Protocol

5 days per week

Taken Monday through Friday at night, on an empty stomach.

200 mcg per injection

200 mcg per injection, given just under the skin in the abdomen or thigh.

Ipamorelin encourages your body to release its own growth hormone and tends to cause fewer side effects than similar peptides. It's usually injected at night on an empty stomach, since that's when the body's own growth hormone surge happens.

What is Ipamorelin?

Ipamorelin is a lab-made peptide that mimics the 'hunger hormone' ghrelin to trigger a clean, natural pulse of growth hormone from the pituitary gland, without raising stress hormones like cortisol the way older peptides do. It was originally developed by a major pharmaceutical company and later tested in human trials for digestive recovery after surgery. It's widely used today in research and wellness settings for body composition, recovery, and healthy aging.

What Does Ipamorelin Do?

It mimics the 'hunger hormone' ghrelin at its receptor in the pituitary gland, triggering a clean pulse of growth hormone release. It also reduces the effect of a hormone that would normally suppress that pulse, all while avoiding activation of the body's stress-hormone pathways.

Frequently Asked Questions About Ipamorelin

Straight answers on reconstitution, dosing, and safety, everything you need to research with confidence. For research reference only.

Most published and vendor research protocols cite doses in the range of roughly 100-300 mcg per subcutaneous administration, given one to three times per day. Ipamorelin has a short half-life (about two hours), so each dose is generally described as producing one discrete GH pulse. These figures come from research-use literature and community-reported protocols, not an approved clinical dosing standard, since Ipamorelin is not an FDA-approved drug for human use.

CJC-1295 is a growth-hormone-releasing hormone (GHRH) analog that signals the pituitary to synthesize and release GH via a different receptor pathway than Ipamorelin, which acts on the ghrelin receptor. Because they act on separate pathways, combining the two is commonly described as producing a larger, more sustained GH pulse than either compound alone, which is why 'CJC-1295/Ipamorelin' is one of the most frequently discussed peptide stacks in research and enthusiast communities.

Sources and user reports describe Ipamorelin's side-effect profile as comparatively mild versus older GH secretagogues like GHRP-2 or GHRP-6. Commonly mentioned effects include mild headache, water retention or bloating, increased appetite, temporary tingling in the hands or feet, mild joint stiffness, transient fatigue, and localized injection-site redness or irritation. A frequently cited distinguishing feature is that Ipamorelin, unlike some other GH-releasing peptides, is reported not to meaningfully raise cortisol, ACTH, or prolactin levels. These are self-reported and research-context observations, not a clinically established safety profile.

Lyophilized (unreconstituted) Ipamorelin powder is generally recommended to be stored frozen or refrigerated and protected from light until use. Once reconstituted, typically with bacteriostatic or sterile water, it is generally recommended to be refrigerated at about 2-8°C (36-46°F) and used within roughly 2-4 weeks; reconstituted peptide should not be frozen. Bacteriostatic water (containing benzyl alcohol as a preservative) is often preferred over plain sterile water when a vial will be used over multiple sessions, since it helps inhibit microbial growth during that window.

Ipamorelin is widely sold by online vendors labeled 'for research use only, not for human consumption,' and it has not been approved by the FDA (or equivalent regulators in most countries) as a drug for human therapeutic use. Its legal status for personal use varies by jurisdiction and is a frequently asked and somewhat unsettled question in peptide communities; buyers should not treat research-labeled sale as equivalent to regulatory approval or medical endorsement.

Across vendor content, clinic marketing, and community discussion, the most frequently cited reported effects include improved sleep quality, increased appetite, changes in body composition (reported fat loss and lean mass gains) over extended use, and enhanced recovery. These are commonly reported outcomes rather than outcomes established through robust human clinical trials, and individual results are widely described as varying.

A commonly repeated protocol in both vendor guides and user discussions is dosing before bed, on the reasoning that it may align with the body's natural nighttime GH release pattern; some protocols also add a dose post-workout or in a fasted state (e.g., morning before eating) on the idea that food, especially carbohydrates, can blunt the GH pulse. These are conventional practices reported in research/enthusiast sources rather than settled pharmacological requirements.

Ipamorelin Reconstitution Guide

Ipamorelin is supplied as a freeze-dried powder that must be mixed into a injectable solution before use. Available in 5mg, 10mg sizes.

10 mg lyophilized vial

Ipamorelin is supplied as a freeze-dried powder that must be mixed into a injectable solution before use. Available in 5mg, 10mg sizes.

3 mL bacteriostatic water

Adding 3 mL of bac water to a 10 mg vial gives a workable concentration for syringe dosing. More water makes microdosing easier; less concentrates each draw.

Storage after mixing

Keep the dry powder well below freezing for up to two years; it can handle room temperature for a few weeks if sealed. Once mixed with bacteriostatic water, refrigerate and use within about a month, and don't refreeze it. After reconstitution, keep the vial refrigerated and use within 30 days.

What Are the Benefits of Ipamorelin?

What research says it may help with, and how it works in the body.

growth hormone

: Raises IGF-1, a hormone tied to growth and repair, by working through the body's normal growth hormone system.
: Helps cells regenerate, supports collagen production, and aids tissue repair.
: Reliably raises growth hormone levels 30 to 60 minutes after injection, while still following the body's natural pattern of releasing it in bursts rather than a constant stream.

body composition

: Supports building and maintaining muscle by boosting the body's natural growth hormone activity.
: Helps the body break down fat and burn calories a bit faster by naturally raising growth hormone.

recovery

: Helps people fall asleep faster and spend more time in deep, restorative sleep.
: May improve recovery after workouts and reduce muscle soreness.

What Are the Side Effects of Ipamorelin?

Who should avoid it, warning signs to watch for, and what to know before combining it with other compounds.

: Unusual joint pain or swelling
: Persistent numbness or tingling

Milder Signs to Watch For

Ipamorelin Cycle Length: How Long Should It Last?

This breaks down how long a typical Ipamorelin cycle runs and what research suggests happens at each stage. Research shows that staying on a peptide continuously, without a break, may make it less effective over time.

That's why most research protocols build in a break between cycles, often called a washout period, to let the body reset before starting again.

Week 1-2: Improved sleep quality and morning energy
Week 2-4: Enhanced exercise recovery and reduced soreness
Week 4-8: Body composition improvements with increased lean mass
Week 8-12: Continued muscle tone, skin quality, and energy improvements

Ipamorelin vs Sermorelin: Key differences comparison

Ipamorelin is a selective ghrelin-receptor agonist that produces a sharp, short GH pulse with little effect on cortisol, prolactin, or appetite hormones. Sermorelin is a GHRH analogue that signals the pituitary directly through a separate receptor, closer to the body's own nighttime GH rhythm. Here's how Ipamorelin and Sermorelin compare.
