GHRP-6 (Growth Hormone Releasing Peptide-6) Primary uses: Muscle growth Growth hormone release Appetite stimulation Injury healing Typical dosing: 100-300mcg, 2-3 times daily Best on empty stomach Duration: 3-6 months Administration: Subcutaneous injection Special notes: Strong appetite increase (pro or con depending on goals) Powerful GH release Can increase prolactin (monitor for gynecomastia) Older peptide, still effective GHRP-2 Primary uses: Growth hormone release Muscle growth Fat loss Typical dosing: 100-300mcg, 2-3 times daily Duration: 3-6 months Administration: Subcutaneous injection Special notes: Similar to GHRP-6 but less hunger Still some prolactin increase Good middle-ground between GHRP-6 and Ipamorelin IGF-1 LR3 (Insulin-like Growth Factor) Primary uses: Muscle growth (most anabolic peptide) Muscle recovery Body recomposition Nutrient partitioning Typical dosing: 40-80mcg daily 4-6 week cycles Duration: Cycles with breaks (not continuous) Administration: Subcutaneous or intramuscular injection Special notes: Very powerful for muscle growth Requires cycling (not for long-term use) Risk of hypoglycemia (carry fast carbs) Advanced peptide (not for beginners) Hexarelin Primary uses: Powerful GH release Muscle growth Appetite stimulation Typical dosing: 100-200mcg, 2-3 times daily Duration: 4-8 weeks, then break (desensitization occurs) Administration: Subcutaneous injection Special notes: Most powerful GHRP Significant hunger increase Desensitization with continuous use (need breaks) Increases prolactin and cortisol more than other GHRPs Learn complete muscle protocols in our best peptides for muscle growth guide
