(3) In certain cases, peptides may influence muscle maintenance and recovery by: Stimulating natural GH and IGF-1 production to promote protein synthesis and muscle repair Enhancing recovery after intense training by supporting tissue regeneration Improving sleep quality, during which the body releases significant amounts of natural growth hormone Contributing to better workout endurance and shorter recovery periods While these effects can be promising, not every peptide has been thoroughly tested in humans, and much of the research is preliminary
The finding shifted understanding of how mitochondria communicate beyond energy production, signaling through circulating peptides that reach distant tissues
The lead author of the 2025 narrative review titled "Regeneration or Risk?" emphasized the urgent need for randomized controlled trials
Tendontendon continuities were reported to have re-established well, with no ossicles forming in other tissues [94,95,96,97,98] (note, with bone morphogenetic proteins (BMPs) [126,127,128], the initial tendon healing process is misleading, due to its similarity to the process of fracture healing [126] and the formation of ossicles in other tissues [126,127,128])
