Comprehensive guide to growth hormone secretagogues. Learn about Ipamorelin, CJC-1295, GHRP-6 and other muscle growth peptides for research and performance.
Mechanism: Ghrelin receptor agonist that stimulates growth hormone release from the pituitary gland. Selective action with minimal side effects.
Research Use: Growth hormone stimulation, muscle growth support, fat loss, improved body composition, joint and bone health.
Typical Dosing: 200-300mcg daily, usually given as subcutaneous injection in evening or pre-workout.
Widely available from all major vendors. Good COA support. Expect $80-200 for 10mg vial.
Mechanism: Growth hormone releasing hormone (GHRH) analog. Stimulates growth hormone release and may increase baseline GH levels over time with repeated dosing.
Research Use: Growth hormone stimulation, muscle building, anti-aging effects, improved recovery, body composition.
Typical Dosing: 100-300mcg, typically 2-3 times per week. Can be used daily or as part of stack with other GH secretagogues.
Available from major vendors. Good availability. Expect $100-250 for 2mg vial.
Mechanism: Growth hormone releasing peptide. More potent ghrelin receptor agonist than Ipamorelin. Increases appetite as side effect.
Research Use: Potent growth hormone stimulation, muscle growth, joint health, improved recovery from training.
Typical Dosing: 100-300mcg daily, typically 1-3 times per day depending on protocol.
Good availability from most vendors. Cost $100-200 for 5mg vial. May need more frequent dosing.
Include: GHRP-2, GHRP-3, Sermorelin, and other growth hormone secretagogues with various mechanisms.
Research Use: Growth hormone stimulation, muscle building, anti-aging, recovery support with varying potencies and effects.
Typical Dosing: Varies by specific peptide. Generally 100-300mcg depending on compound.
Availability depends on specific peptide. Research thoroughly before selecting.
| Peptide | Potency | Side Effects | Dosing Frequency | Best For | Cost |
|---|---|---|---|---|---|
| Ipamorelin | Moderate | Minimal | Daily | Long-term use, low side effects | $$ |
| CJC-1295 | High | Minimal | 2-3x weekly | Potent GH stimulation | $$ |
| GHRP-6 | Very High | Appetite increase | 1-3x daily | Bulking, maximum GH | $$ |
| CJC + Ipamorelin Stack | Synergistic | Minimal | Daily/2-3x weekly | Best results, balanced | $$$ |
| GHRP-6 + CJC-1295 Stack | Maximum | Appetite increase | Frequent dosing | Aggressive muscle building | $$$ |
Growth peptides work best with pulsatile (intermittent) dosing to mimic natural growth hormone secretion patterns. Continuous exposure can lead to desensitization.
This is why multiple daily doses at intervals work better than one large daily dose.
Evening dosing (7-10pm) aligns with natural growth hormone peaks during sleep. Pre-workout dosing captures training stimulus synergy.
Avoid dosing immediately after meals (food can blunt GH response).
Ipamorelin: Minimal. CJC-1295: Minimal. GHRP-6: Appetite increase, potential bloating.
All are well-tolerated by most researchers. Start conservative and assess tolerance.
Run 8-12 weeks on, take 4-8 weeks off to prevent desensitization. Some protocols use 5 days on, 2 days off approach.
Extended cycling helps maintain effectiveness long-term.
