Best peptides for Muscle Growth
Growth hormone secretagogues (Ipamorelin, CJC-1295, MK-677, Hexarelin, GHRP-2, GHRP-6), IGF-1 analogs (IGF-1 LR3, IGF-1 DES, MGF), and myostatin inhibitors (ACE-031, Follistatin-344) dominate the muscle-growth peptide literature. Each entry below links to the full research profile with study counts and trial-phase data.
Examorelin | Synthetic Growth Hormone Secretagogue
Hexarelin is a synthetic hexapeptide that belongs to the growth hormone secretagogue (GHS) class, known for its ability to stimulate growth hormone release from the pituitary gland. It has been investigated for its potential therapeutic applications in various conditions, including muscle wasting and age-related decline in growth hormone levels.
Growth Hormone Releasing Peptide-2 | Pralmorelin
GHRP-2 (pralmorelin) is a synthetic hexapeptide and ghrelin-receptor agonist studied as a growth hormone secretagogue, used clinically as a diagnostic agent and investigationally for GH-related research.
Growth Hormone Secretagogue | Selective GHRP
Ipamorelin is a synthetic peptide that acts as a selective agonist of the growth hormone secretagogue receptor, primarily stimulating growth hormone release. Its potential therapeutic applications are being explored in various contexts, including weight management and pain modulation.
GHRH/GHRP Combination | Growth Hormone Optimization
CJC-1295/Ipamorelin is a research peptide stack pairing a GHRH analog with a selective ghrelin receptor agonist to amplify endogenous growth hormone release.
