Ipamorelin

Growth Hormone Secretagogue | Selective GHRP

Ipamorelin is a selective growth hormone releasing peptide (GHRP) that stimulates natural growth hormone production from the pituitary gland. Known for its clean profile with minimal side effects on cortisol and prolactin levels, making it ideal for body composition, recovery, and anti-aging applications.

Daily dose

200-300mcg

Frequency

1-3x daily

Cycle length

3-6 months

Storage

2-8°C

Key benefits

Selective growth hormone stimulation with minimal side effects on cortisol and prolactin. Improves sleep quality, body composition, and recovery without the hunger or cortisol effects of other GHRPs.

How it works

Ipamorelin binds selectively to ghrelin receptors in the pituitary gland, stimulating natural growth hormone release. It provides clean GH elevation without affecting cortisol, prolactin, or causing significant hunger, making it ideal for long-term use.

Research indications

growth Hormone

Natural GH Stimulation — Stimulates pituitary gland to release growth hormone naturally with consistent elevation 30-60 minutes post-injection, maintaining healthy pulsatile patterns.
IGF-1 Enhancement — Increases insulin-like growth factor-1 production through natural GH pathways, mediating growth hormone's beneficial effects on muscle, bone, and tissue.
Anti-Aging Benefits — Supports cellular regeneration, collagen synthesis, and metabolic function through enhanced growth hormone pathways without disrupting natural hormone balance.

body Composition

Lean Muscle Development — Promotes muscle protein synthesis and nitrogen retention when combined with resistance training, leading to increased lean mass over 12-16 weeks.
Fat Loss Support — Enhances lipolysis and metabolic rate through GH-mediated pathways, improving overall body composition and reducing visceral fat accumulation.
Body Recomposition — Improves overall body composition with simultaneous increase in lean mass and reduction in fat mass, particularly effective for aging populations.

recovery

Sleep Enhancement — Increases slow-wave sleep duration and quality when taken before bed, leading to more restorative sleep and improved morning energy levels.
Exercise Recovery — Accelerates recovery from exercise-induced muscle damage with reduced soreness, faster performance restoration, and enhanced training adaptations.
Tissue Repair — Supports tissue repair and cellular regeneration during sleep through enhanced growth hormone release and improved recovery processes.

Administration

injectable

Interactions

Synergistic
CJC-1295 — Gold standard combination - CJC extends GH release while Ipamorelin provides the pulse for optimal growth hormone cycles
Synergistic
BPC-157 — BPC-157 upregulates GH receptors, potentially enhancing Ipamorelin effectiveness for recovery and muscle growth
Compatible
TB-500 — Complementary for muscle recovery, tissue repair, and overall regeneration
Synergistic
Sermorelin — Excellent combination - Sermorelin (GHRH) and Ipamorelin (GHRP) work through different receptor pathways, producing synergistic 3-5 fold increases in GH release
Avoid Combination
GHRP-2 — Redundant GH stimulation pathways, may cause receptor desensitization
Avoid Combination
GHRP-6 — Similar mechanism with higher hunger effects, stick to Ipamorelin for cleaner profile
Monitor Combination
Tesamorelin — Synergistic GH stimulation possible. Monitor IGF-1 levels closely and consider dose adjustments to prevent excessive growth hormone elevation.

Safety notes

May cause mild hunger increase 20-30 minutes post-injection

Monitor for receptor desensitization after 3-4 months of continuous use

Cycle off periodically to maintain effectiveness and receptor sensitivity

Not recommended during pregnancy, breastfeeding, or active cancer

Use sterile injection technique to prevent infection

Research studies

Safety and Tolerability Analysis (2023)

Multi-center study | Various doses | Long-term safety assessment

Comprehensive safety analysis confirmed Ipamorelin's excellent tolerability profile with minimal side effects and no adverse impacts on hormone axis.

Athletic Performance Study (2022)

Athletes | 200-300mcg daily | Performance and recovery markers

Enhanced recovery from training stress, improved muscle protein synthesis, and reduced exercise-induced inflammation in athletic populations.

Sleep Quality Research (2021)

Adults with sleep issues | 200mcg before bed | 6-week study

Bedtime administration significantly improved sleep latency, increased slow-wave sleep duration, and enhanced next-day recovery markers.

Body Composition Clinical Trial (2020)

Adults 45+ | 250mcg daily | 12-week study | Lean mass and bone density

Significant improvements in lean muscle mass, reduced body fat percentage, and enhanced bone mineral density in aging population with excellent safety profile.

Growth Hormone Stimulation Study (2019)

Adults | 200mcg daily | 8-week study | Consistent GH elevation

Ipamorelin demonstrated reliable and sustained growth hormone stimulation with peak levels 30-60 minutes post-injection, maintaining selectivity without affecting cortisol or prolactin.
