Ipamorelin Protocol: Complete Cycling & Dosing Guide
Overview
Ipamorelin is a synthetic pentapeptide that functions as a selective growth hormone secretagogue (GHS), triggering pulsatile endogenous GH release through ghrelin receptor activation. Unlike exogenous growth hormone, ipamorelin stimulates your body's own GH production, making it favorable for maintaining natural feedback mechanisms and avoiding receptor downregulation at standard doses.
The compound binds to GHS-R1a receptors in the pituitary and hypothalamus, activating intracellular signaling cascades that result in dose-dependent GH secretion. This endogenous GH stimulates IGF-1 production in the liver, which mediates the majority of downstream anabolic, lipolytic, and regenerative effects. Critically, ipamorelin exhibits high selectivity for GH release with minimal impact on cortisol, prolactin, or ACTH at therapeutic doses—a significant advantage over older GH secretagogues.
Administration Route: Subcutaneous injection only
Typical Dosing Window: 200–300 mcg per injection
Frequency Range: 1–3 times daily
Cost Range: $40–$120 monthly
Half-Life: Approximately 2 hours
Time to Peak GH: ~40 minutes post-injection
Standard Protocol
The baseline protocol for ipamorelin follows a simple structure: inject once or twice daily subcutaneously, typically in the abdominal region, and cycle strategically to prevent tachyphylaxis and maintain pituitary responsiveness.
Dosing Structure
Beginner Dose (First 2 Weeks)
- 100 mcg once daily, preferably in the morning
- This allows assessment of tolerance and individual sensitivity
- Observe for flushing, mild headache, or lightheadedness
Standard Dose (Weeks 3+)
- 200 mcg once or twice daily
- Morning injection is conventional; if using twice daily, separate doses by 6–8 hours
- Evening dosing (6–8 PM) is acceptable but may trigger hunger before bed
Higher Dose Option
- 300 mcg once or twice daily
- Reserve for advanced users with demonstrated tolerance
- Monitor for increased water retention and appetite stimulation
Cycle Timing
The most practical cycling approach alternates between "on" and "off" periods to maintain receptor sensitivity:
5 Days On / 2 Days Off Cycling
- Inject Monday through Friday at your target dose
- Rest Saturday and Sunday
- This prevents down-regulation while maintaining consistent GH stimulus
- Repeat indefinitely for sustained use
Alternatively: 6 Weeks On / 1–2 Weeks Off
- Run full dose for 6 consecutive weeks
- Take 1–2 weeks completely off ipamorelin
- Resume at standard dose
- This pattern allows deeper pituitary recovery and prevents tolerance creep
Aggressive 24/7 Protocol (Not Recommended)
- Continuous daily dosing without off days
- Risk of tachyphylaxis increases significantly after 8–12 weeks
- Typically results in diminished GH response by week 10–12
- Only use if cycling is absolutely impractical, and plan a 2–3 week break every 8 weeks
Goal-Specific Protocols
Protocol for Muscle Preservation & Recovery
Duration: 8–12 weeks
Dosing: 200 mcg twice daily (morning and evening)
Cycle: 5 days on / 2 days off, or continuous with 2-week break after 6 weeks
Rationale: Twice-daily dosing maintains more consistent GH stimulus for anabolic signaling. The IGF-1 elevation supports nitrogen retention and satellite cell activation.
Monitoring: Track body composition via scale, circumference measurements, or DEXA scan. Expect preservation of lean mass during caloric restriction more so than frank muscle gain.
Protocol for Fat Loss & Body Composition
Duration: 12–16 weeks
Dosing: 200 mcg once daily (morning preferred)
Cycle: 5 days on / 2 days off
Rationale: Single daily dosing is sufficient to stimulate GH for lipolytic signaling. Morning injection aligns with natural GH pulses and morning cortisol rhythm. Longer cycle duration allows more consistent fat loss signaling.
Caution: Ipamorelin may increase appetite through ghrelin activity; manage caloric intake accordingly. Some research suggests potential for increased fat deposition in specific contexts—diet quality and training intensity remain paramount.
Protocol for Injury Recovery & Joint Health
Duration: 10–14 weeks minimum
Dosing: 300 mcg once or twice daily
Cycle: Continuous (6 weeks on / 2 weeks off) to maximize IGF-1 signaling for tissue repair
Rationale: Higher dosing and continuous administration theoretically optimize IGF-1 levels for collagen synthesis and chondrocyte activity. No human data confirms efficacy, but mechanistic evidence supports this approach.
Expected Timeline: 4–6 weeks before subjective improvement in joint symptoms; 8–12 weeks for measurable structural changes if they occur.
Protocol for Anti-Aging & General Health Optimization
Duration: Indefinite (with cycling breaks)
Dosing: 200 mcg once daily
Cycle: 5 days on / 2 days off, rotating every 6 weeks with 10–14 day breaks
Rationale: Moderate single-daily dosing maintains IGF-1 elevation without excess water retention. Cycling prevents receptor desensitization and allows physiological recovery periods.
Monitoring: Track skin elasticity, recovery speed, energy levels, and general wellness markers subjectively. Objective markers include IGF-1 serum levels (measure every 8–12 weeks) and body composition.
How to Administer Step-by-Step
Preparation
-
Reconstitution (if using lyophilized powder):
- Use sterile bacteriostatic water (0.9% sodium chloride or similar)
- Calculate volume needed: 1 mg vial + 1 mL water = 1 mg/mL concentration
- Draw appropriate volume into syringe and slowly inject into vial
- Do NOT shake; gently roll vial between palms for 30–60 seconds until fully dissolved
- Solution should be clear; discard if cloudy or discolored
-
Storage:
- Keep lyophilized (unreconstituted) powder in cool, dry place; refrigeration not required
- Reconstituted solution must be refrigerated (2–8°C) after mixing
- Use reconstituted ipamorelin within 3–4 weeks for optimal stability
- Mark vial with reconstitution date using permanent marker
Injection Technique
-
Site Selection:
- Preferred sites: abdominal subcutaneous tissue (2 inches from navel), upper thigh, back of upper arm
- Rotate injection sites daily to prevent lipohypertrophy
- Mark a mental map: Monday = right abdomen, Tuesday = left abdomen, Wednesday = right thigh, etc.
-
Preparation:
- Wash hands thoroughly with soap and water
- Wipe injection site with alcohol swab; allow to dry (don't blow dry)
- Remove insulin syringe from package and ensure needle is intact
- Draw back plunger to desired volume (typically 0.2 mL for 200 mcg at 1 mg/mL concentration)
-
Injection:
- Pinch skin at injection site between thumb and forefinger
- Insert needle at 45-degree angle quickly and smoothly
- Release pinched skin; inject slowly over 2–3 seconds
- Withdraw needle and apply light pressure with gauze for 5 seconds if any bleeding occurs
-
Post-Injection:
- Expect mild transient flushing or warmth within 2–5 minutes (normal)
- Mild headache may appear within 10–20 minutes; typically resolves within 30–60 minutes
- Remain seated or lie down if lightheadedness occurs on first dose
