How to Use Ipamorelin: Complete Dosing and Protocol Guide
Step-by-step guide to using ipamorelin — optimal dosing (100–300mcg), injection timing, cycle length, and how to stack with CJC-1295.
Overview
Ipamorelin is a selective growth hormone secretagogue that stimulates GH release with minimal effect on cortisol or prolactin. It is one of the most popular peptides for body composition, recovery, and sleep quality. This guide covers reconstitution, dosing, timing, and cycling.
What You Need
- Ipamorelin vial (2–5mg)
- Bacteriostatic water (2mL)
- Insulin syringes (U-100)
- Alcohol swabs
- Sharps container
Step-by-Step Instructions
Reconstitute the vial
Add 2mL of bacteriostatic water to a 5mg ipamorelin vial. This gives a concentration of 2.5mg/mL (2500mcg/mL). Swirl gently — do not shake.
Calculate your dose volume
Standard dose: 100–300mcg per injection. At 2500mcg/mL: 200mcg = 0.08mL = 8 units on a U-100 syringe. At 1000mcg/mL: 200mcg = 0.2mL = 20 units.
Choose your injection timing
Ipamorelin works best when GH release is already elevated: fasted state (morning), pre-sleep (30–60 min before bed), or post-workout. Avoid injecting within 2 hours of a carbohydrate-heavy meal.
Inject subcutaneously
Inject into the abdomen, outer thigh, or upper arm. Rotate sites. Use a 29–31 gauge insulin syringe at a 45° angle.
Follow a cycle protocol
Typical cycle: 8–12 weeks on, 4 weeks off. Some users run continuous low-dose protocols (100mcg/day) for 6+ months. Monitor for water retention, tingling, or lethargy — these indicate the dose may be too high.
Common Mistakes to Avoid
Injecting after a carb-heavy meal
Fix: High insulin suppresses GH release. Inject in a fasted state or at least 2 hours after a meal for maximum effect.
Starting at maximum dose
Fix: Begin at 100mcg to assess individual response. Many users find 100–150mcg is sufficient.
Not rotating injection sites
Fix: Rotate between abdomen, thigh, and arm to prevent lipodystrophy and maintain consistent absorption.
Frequently Asked Questions
How long does it take for ipamorelin to work?
Most users notice improved sleep quality within 1–2 weeks. Body composition changes (fat loss, lean mass) typically become noticeable after 6–8 weeks of consistent use.
Should I stack ipamorelin with CJC-1295?
The ipamorelin + CJC-1295 (no DAC) stack is one of the most popular combinations. CJC-1295 extends the GH pulse while ipamorelin triggers it, resulting in a larger, more sustained release.
What are the side effects of ipamorelin?
Common side effects at higher doses include water retention, mild tingling in the hands/feet, and transient headache. These typically resolve with dose reduction. Ipamorelin does not significantly raise cortisol or prolactin.
