Type
Ipamorelin is a synthetic pentapeptide and selective growth hormone secretagogue that mimics ghrelin to stimulate pulsatile GH release from the pituitary without significantly elevating cortisol, prolactin, or ACTH. Originally developed by Novo Nordisk and later investigated by Helsinn Therapeutics in Phase 2 trials for postoperative ileus, it is widely used in research and clinical wellness settings for body composition, recovery, and longevity. Its high receptor selectivity distinguishes it from older GHRPs, making it a preferred tool for GH axis modulation.
Top researched benefits
Growth Hormone Stimulation Study
200mcg daily for 8 weeks showed consistent GH elevation 30-60 min post-injection in adults.
Body Composition Clinical Trial
250mcg daily for 12 weeks demonstrated lean mass gains and bone density improvements in adults 45+.
Overview of Ipamorelin
Ipamorelin selectively binds and activates the ghrelin/growth hormone secretagogue receptor (GHS-R1a) on pituitary somatotroph cells, triggering pulsatile GH secretion. It also attenuates somatostatin-mediated inhibition in the hypothalamus, amplifying the natural GH pulse without engaging ACTH or cortisol pathways.
growth hormone
- Consistent GH elevation 30-60 minutes post-injection, maintaining natural pulsatile patterns.
- Increases insulin-like growth factor-1 through natural GH pathways.
- Supports cellular regeneration, collagen synthesis, and tissue repair.
body composition
- Promotes muscle growth and maintenance through GH-mediated pathways.
- Enhances lipolysis and metabolic rate through natural GH elevation.
recovery
- Improved sleep latency and increased slow-wave sleep duration.
- Enhanced recovery markers and reduced soreness after training.
Typical Dose
200–300mcg per injection
Frequency
2–3 times daily
Cycle Duration
8–12 weeks on, 2–4 weeks off
Storage
Lyophilized: store below -18°C, stable up to 24 months; stable at room temp for up to 3 weeks if sealed. Reconstituted in bacteriostatic water: refrigerate at 2–8°C, use within 28 days; do not refreeze.

PeptideIpamorelin Protocols
Subcutaneous injection is the primary and most effective delivery route for Ipamorelin, a selective pentapeptide GH secretagogue. Injections are timed 30 minutes before sleep to align with the natural nocturnal GH pulse, or in a fasted morning state for fat loss protocols.

Ipamorelin Reconstitution Guide
Learn how to reconstitute Ipamorelin
Materials needed
Ipamorelin lyophilized powder vial (2 mg, 5 mg, or 10 mg)
Bacteriostatic water (BAC water), 3.0 mL per 10 mg vial
Insulin syringes (0.5–1 mL, 29–31 gauge)
Alcohol swabs
Sharps disposal container
Allow the sealed lyophilized Ipamorelin vial to reach room temperature (18–22°C) for 15–20 minutes before reconstitution
Draw 3.0 mL of bacteriostatic water into a sterile syringe (this yields approximately 3.33 mg/mL for a 10 mg vial)
Insert the needle into the Ipamorelin vial and inject the BAC water slowly down the inside wall — never aim the stream directly onto the powder
Remove the syringe and gently roll the vial between your palms until the powder is fully dissolved — do not shake or vortex
Label the vial with the reconstitution date and store at 2–8°C away from light; use within 28 days
To draw a dose, wipe the vial stopper with an alcohol swab and allow it to dry completely
Wipe the injection site (abdomen, thigh, or upper arm) with an alcohol swab and allow to dry
Pinch a fold of skin and insert the insulin syringe at a 45–90° angle into the subcutaneous tissue
Inject slowly over 3–5 seconds without aspirating, then withdraw the needle and apply gentle pressure — do not rub
Rotate injection sites with every administration and dispose of used syringes in an approved sharps container
Ipamorelin Cycle
The Ipamorelin Cycle section explains how long a typical cycle lasts and what to expect during each phase. Over time, your body can become less responsive with continuous use.
Taking breaks between cycles may help maintain effectiveness and support better overall results.
- 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

Frequently asked questions
What is a peptide dosage calculator?
A peptide dosage calculator is a free tool that converts your vial size, bacteriostatic water volume, and target dose into an exact syringe draw volume. Instead of doing the reconstitution math by hand, you enter three inputs and instantly get the concentration of your solution and how many milliliters or syringeunits to draw. This calculator works for single peptide compounds and multi-peptide blends.
How do I calculate peptide dosage from a vial?
To calculate your peptide dose, divide the total peptide content of your vial in micrograms by the volume of bacteriostatic water you added in milliliters. This gives you your solution concentration in mcg/mL. Then divide your target dose by that concentration to get your draw volume. For example, a 5mg (5,000 mcg) vial reconstituted with 2mL of BAC water gives a concentration of 2,500 mcg/mL. A 250 mcg dose would require drawing 0.1mL. This calculator automates all of those steps instantly.
How much Bacteriostatic water should I add to a peptide vial?
Most people add 2mL to 3mL of bacteriostatic water per vial, but the right amount depends on the dose you want to draw and the syringe size you are using. Adding 1mL to a 5mg vial gives you a concentration of 5,000 mcg/mL, making each dose very small in volume. Adding 2mL gives you 2,500 mcg/mL, which is easier to measure on a standard insulin syringe. A general guideline is to choose a volume that puts your typical dose somewhere between 10 and 30 units on a U-100 syringe. Use the calculator above to test different water volumes and find what works for your dose.
How are peptides different from proteins?
Both are made of amino acids, but peptides are much smaller than proteins. Because of their tiny size, peptides can act like tiny messengers in the body, sending specific signals to your cells to tell them exactly what to do.
