10 peptides researched for muscle growth.
Muscle growth peptides primarily work by stimulating your body's natural production of growth hormone (GH). Rather than injecting synthetic GH directly, these compounds trigger the pituitary gland to release more GH through natural pathways. This approach preserves the body's feedback mechanisms and pulsatile release pattern, which may offer a better safety profile than exogenous GH.
CJC-1295 and ipamorelin work through different receptors. CJC-1295 mimics GHRH (the "release" signal) while ipamorelin mimics ghrelin (the "hunger" signal that also triggers GH). They're often combined for synergistic effects. MK-677 (ibutamoren) is technically not a peptide but a non-peptide oral GH secretagogue. convenient since it's taken by mouth, but it also stimulates appetite and may affect blood sugar. Sermorelin is another GHRH analog with a shorter duration of action.
