Best Peptides for Muscle Wasting
Loss of muscle mass due to disease, injury, or prolonged inactivity (cachexia/atrophy).
Muscle wasting, or cachexia, refers to involuntary loss of muscle mass occurring in response to disease, injury, prolonged immobility, or aging. Research peptides such as GHRP-6 and GHRP-2 are being investigated for their ability to stimulate growth hormone release and influence metabolic signaling pathways that may support muscle preservation. These ghrelin-mimetic peptides work through the GHS-R receptor to potentially counteract the catabolic state characteristic of muscle wasting, though human clinical evidence remains limited.
Research protocols for muscle wasting typically employ subcutaneous or intramuscular administration, often administered multiple times daily to optimize GH stimulation timing. Protocol design varies significantly based on individual research goals, baseline metabolic status, and the specific peptide selected, making consultation with research guidelines essential before any protocol initiation.
Peptides Studied for Muscle Wasting
| Peptide | Evidence | Notes | Actions |
|---|---|---|---|
| GHRP-2 Growth Hormone Releasing Peptide 2 (GHRP-2) is considered one of the most potent GHRPs available. It provides strong GH release with moderate hunger increase compared to GHRP-6. | medium | — | |
